Pneumococcal bacteraemia during a recent decade. Infection results in fever and causes liver damage, inflammation of the intestines, and damage to lymph nodes, followed by a disorder of blood clotting and bleeding within multiple organs. Use OR to account for alternate terms Croisier-Bertin D., Piroth L., Charles P.E., Larribeau A., Biek D., Ge Y., Chavanet P. Ceftaroline versus Ceftriaxone in a Highly Penicillin-Resistant Pneumococcal Pneumonia Rabbit Model Using Simulated Human Dosing. CF-370: , , - This comprehensive narrative review attempted to describe the different characteristics of the most commonly used animal models in pneumococcal science. Veterinarians or laboratories that diagnose one of these diseases must report it to certain local, state, and national agencies. Inoculation can be both surgical and non-surgical [76]. Most domestic rabbits can easily live to be 8 years old, and many can live Individuals 75 years old or older accounted for 76.0% of aspiration pneumonia deaths and the age adjusted rate ratio was 161.0 (CI 160.5161.5). There is no effective treatment for infected rabbits. Use outbred rabbits with normal immune system (not neutropenic) percent survival. WebThe animals were euthanized on day 4, and survival and pulmonary histopathology were compared between groups. The bacteria also can infect people, and up to 90% of human cases are linked to wild rabbit exposure. Tularemia (infection with Francisella tularensis bacteria) is rare in domestic rabbits, but wild rabbits and rodents are highly susceptible and have been involved in most outbreaks. Other signs include discharge of pus from the nose, difficulty breathing, and coma. In pet rabbits, the infected reproductive organs are usually removed surgically and antibiotics given. Some affected rabbits have a head tilt. Papillomas and Shope fibromas are 2 types of benign skin tumors that occur in rabbits ( see Shope Fibromas Shope Fibromas Rabbits fed a suitable diet and kept in a healthy environment can live as long as 10 to 12 years. To collect BAL, a small volume (usually 1 mL) of sterile saline is instilled into the animals lungs and immediately removed. Fur mites are also common on rabbits. There are 2 forms of the disease: hepatic, which affects the liver, and intestinal, which affects the intestines. Moreover, penicillin-resistant pneumococcal strains and other resistant phenotypes have been established in the existing rat models in order to evaluate the efficacy of new antibiotics [78,83]. Of note, in 1996, Iizawa and colleagues [71] elaborated a model in which nasopharyngeal carriage was achieved through the aerosol route and pneumonia was subsequently induced by airway obstruction caused by IT instillation of 20 L of 2% formalin. Clostridium spiroforme bacteria are the usual cause of enterotoxemia. Winter C., Taut K., Lnger F., Mack M., Briles D.E., Paton J.C., Maus R., Srivastava M., Welte T., Maus U.A. Cardiac complications post-pneumococcal pneumonia have been reported in NHPs. NLRP3 inflammasome activation in aged macrophages is diminished during Streptococcus pneumoniae infection. Intestinal coccidiosis can occur regardless of the conditions in which rabbits are housed. If you notice that your rabbit has stopped eating or has other signs of a digestive problem, see your veterinarian promptly. The condition is extremely contagious and can be transmitted to humans. The fibromas usually occur on the legs, feet, and ears. These parasites irritate the lining of the ear and cause fluid and thick brown crusts to build up, creating an ear canker. Infested rabbits scratch and shake their head and ears. Efficacy of antimicrobial chemotherapy in experimental rat pneumonia: Effects of impaired phagocytosis. Escherichia coli bacteria can also cause diarrhea in rabbits; this disease is called colibacillosis. The position of the animal during instillation has shown little impact on delivery of the inoculum [64]. VIN Another group used nonsurgical transthoracic inoculation of pneumococci entrapped in cooled agar particles into the mid-right lungs [79]. Hutches should be kept dry and the feces removed often. Kits should not be fostered to another doe because they will spread the infection. Hot, humid weather, along with poorly ventilated hutches or transport in poorly ventilated vehicles, may cause death, particularly in pregnant does. Swine models can be a result of a naturally developed pneumonia due to a porcine pathogen (Streptococcus suis), which cause a pneumonia similar to that occurring in humans. pneumonia A model of pneumococcal pneumonia in chronically intoxicated rats. Shinohara M., Kibi M., Riley I.R., Chiang N., Dalli J., Kraft B.D., Piantadosi C.A., Choi A.M., Serhan C.N. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (, signs of a consolidation with asymmetric chest expansion. A study by Thevaranjan et al. Pathogenesis is one of the major goals of rabbit models, according to our research. In the IN model, the bacterial suspension is applied into the nostrils through a pipette tip. The economic costs are staggering, with estimates ranging from nearly 20 billion dollars to more than 80 billion dollars per year in the US (136, 189, 565). Signs are gelatinous or mucus-covered droppings, loss of appetite, loss of energy, low body temperature, dehydration, rough coat, and often a bloated abdomen due to excess water in the stomach. This narrative review will focus on the characteristics of the different animal pneumococcal pneumonia models. Good sanitation programs that can eliminate hepatic coccidiosis do not seem to eliminate intestinal coccidiosis. Ask your veterinarian for a treatment recommendation if your rabbit has fleas. Lower respiratory tract infections, as defined in the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016, include pneumonia and bronchiolitis [1]. Cottontail rabbits and jackrabbits are not susceptible. 1 2. We do not control or have responsibility for the content of any third-party site. It is shed in the droppings of infected rabbits and is probably transmitted by the droppings-mouth route. government site. Cytokine kinetics and other host factors in response to pneumococcal pulmonary infection in mice. Clement C.G., Evans S.E., Evans C.M., Hawke D., Kobayashi R., Reynolds P.R., Moghaddam S.J., Scott B.L., Melicoff E., Adachi R., et al. The rabbit thoracic cavity is small and the thymus, which is located in the cranial mediastinum, persists in the adult. The likelihood of developing this cancer is related to breed. Finally, we recommend swine models are also very useful for vaccine research, because vaccines can be administered by IM, subcutaneous, intradermal, oral, or IN routes. CXR: chest X-rays; CT: computerized tomography; US: ultrasounds. B Dev. WebUse survival as primary endpoint (not 2-log 10 reduction in CFU) in efficacy studies Our goals for the development of Acute Pneumonia and VAP rabbit models 1. Finally, rabbit models are also suitable to study and evaluate pneumococcal sepsis. Guckian J.C. Coagulopathy in experimental sepsis with Streptococcus pneumoniae in rabbits: Effect of drug therapy and splenectomy. These tumors may persist for several months before regressing, leaving the rabbit essentially normal. Invasive pneumococcal disease leads to activation and hyperreactivity of platelets. Tyzzer disease, caused by Clostridium piliforme bacteria, is characterized by large amounts of watery diarrhea. The etiologic agent is Pasteurella multocida, a gram-negative, nonmotile coccobacillus. Coln D., Horton J., Ogden M., Williams S. Clearance of pneumococcal organisms after repair of injured spleens. Several factors, including a buildup of urine-soaked droppings, nervousness, hind-end paralysis after a spinal cord injury, and the type of wire used, may influence development of this disease. Wang Y., Jiang B., Guo Y., Li W., Tian Y., Sonnenberg G.F., Weiser J.N., Ni X., Shen H. Cross-protective mucosal immunity mediated by memory Th17 cells against Streptococcus pneumoniae lung infection. Azoulay-Dupuis E., Vallee E., Veber B., Bedos J.P., Bauchet J., Pocidalo J.J. According to us, swine models are best suited to evaluate ventilator-associated pneumonia. Characterization of an animal model of ventilator-acquired pneumonia. Rabbit pinworms cannot be transmitted to humans. Accessibility Rabbits are prone to ulcers or trauma to the cornea because of their large eyes and because they do not blink as often as other species, so the cornea is not as moist. Your rabbits cage and other living areas should be thoroughly sanitized. Regular grooming will allow you to check your rabbits skin and identify potential problems early. Saladino R.A., Stack A.M., Fleisher G.R., Thompson C.M., Briles D.E., Kobzik l Siber G.R. Guckian J.C., Morrey B.F., Kirby H.B. As mentioned earlier in the Mouse and pneumococcal strains section above, Swiss mice have been largely used in literature to build the neutropenic model. Another important aspect related to pneumococcal infections is the persistent rate of penicillin and macrolide resistance. This makes them ideal for inducing infection with less virulent pneumococcal serotypes. WebBelow are the 10 highest and 10 lowest pneumonia/influenza death rates per state. 8600 Rockville Pike Horse versus Rabbit Antithymocyte Globulin in Acquired Aplastic Lethal pneumonia in a captive juvenile chimpanzee (Pan troglodytes) due to human-transmitted human respiratory syncytial virus (HRSV) and infection with Streptococcus pneumoniae. Possible contributing factors include obesity and lack of exercise. The advantages of an animal model of VAP are based on the accurate control of significant variables such as the precise timing of the infectious challenge, the effect of antimicrobial therapy on cultures, and the possibility to perform accurate pharmacokinetic and pharmacodynamic studies on drugs [119]. Antifungal drugs are usually effective in treating ringworm. Ear mites are common in rabbits. To our knowledge, limited information is available regarding swine models of pneumococcal infection. Affected rabbits may live for about 1 week. Results. All rights reserved. Leung L.S., Szal E.G.J., Drachman R.H. The most common diseases of rabbits include digestive system problems, respiratory infections read more ). In the USA, myxomatosis is restricted largely to coastal areas of California and Oregon. The Veterinary Manual was first published in 1955 as a service to the community. Streptococcus pneumoniae pneumonia in mice: Optimal amoxicillin dosing predicted from a pharmacokinetic-pharmacodynamic model. The major aims of studies on rat models of pneumococcal pneumonia consist in collecting data on pathogenesis, survival, bacterial counts in lung and blood, pathological and histological characteristics, drug efficacy, and vaccine evaluation both in adults and children (Table 3). To treat ketosis, your veterinarian may inject fluids that contain glucose. Stimulation of lung innate immunity protects against lethal pneumococcal pneumonia in mice. Chiavolini D., Pozzi G., Ricci S. Animal Models of Streptococcus pneumoniae Disease. Fever is often present. Overall, the death rate from pneumonia among people aged 65 and older is 93.2 per 100,000 people, but this is better broken down into further age categories. Surgical procedures on the ear may be necessary if medical treatment alone does not resolve the infection. FOIA The condition is generally suspected when blood is found in the urine. The chronic ethanol intoxication model was created by a continuous ethanol administration [87]. Other studies [74] assessed pneumococcal pneumonia pathogenesis in emphysematous patients by inducing emphysema through IT instillation of porcine pancreatic elastase. The animal is intubated orotracheally with a metal cannula that is advanced generally into the left main bronchus. Some of these diseases can also be passed from rabbits to people ( see Diseases that can be Spread from Rabbits to People Diseases that can be Spread from Rabbits to People ). Some authors expose the trachea in order to visualize the position of a needle inserted through the mouth, allowing accurate administration of the bacteria without the need to incise the airways [61]. Some authors utilize chambers with individual compartments to prevent the animals from huddling and assure uniform exposure to the aerosol and decontaminate the mice coats with UV light for 5 min [70]. Corneal ulcers are treated with antibiotic eye ointments and sometimes with surgery. Papillomas in the mouth, caused by rabbit oral papillomavirus, are small, gray-white lumps or warts on the bottom of the tongue or on the floor of the mouth. Another important aspect related to pneumococcal infections includes the persistent rates of penicillin and macrolide resistance that represent a challenge for patients with this condition [6,7,8]. Merck & Co., Inc., Rahway, NJ, USA(known as MSD outside of the US and Canada) is dedicated to using leading-edge science to save and improve lives around the world. There is little evidence that antibiotics are helpful. Insects and ticks transmit the virus; therefore, insect control could be used as means of disease prevention. Proctor M., Manning P.J. Pneumococcal colonization and invasive disease studied in a porcine model. Disease is usually mild, but growing rabbits may fail to gain weight. Splay leg is a condition in which 1 or more legs extend sideways from the body at an abnormal angle. All authors critically reviewed the final manuscript. The tongue is then displaced anteriorly with a retractor and the microorganism is instilled through the upper airways while the animal is inhaling [16,47,51,52,53]. As for mice, S. pneumoniae is not part of the nasopharyngeal microbial community under normal circumstances. Clinical symptoms and survival rate. A value of p < 0.05 was set as statistical significance. Factors that contribute to the disease include recent dietary changes, too much or too little fiber in the diet, antibiotic treatment, environmental stress, and infection with other bacteria. Smith G.M., Slocombe B., Abbott K.H., Mizen L.W. There is an important interest in assessing whether NHP including rhesus monkeys could be suitable to assess pneumococcal components (e.g., IgA protease, capsular polysaccharide) and the relationship with pathogenesis (i.e., production of antibodies) during pneumococcal infection [129,130,131]. A swine model of pneumococcal infection, used to assess pneumococcal invasive disease after S. pneumoniae serotype 8 IV administration, developed bacteremia with high pneumococcal bacterial burden within 48 h post inoculation [125]. Transmission is by direct contact. Fresh pineapple juice (which contains the digestive enzyme bromelain) and papaya (which contains the enzyme papain) may help break down the mucus holding the hairball together. This is a reportable disease, which means that any veterinarian who identifies it must notify the appropriate government authorities. However, studies on causes and rates of mortality on rabbit farms during pre- and postweaning stages are limited. Andisi V.F., Hinojosa C.A., De Jong A., Kuipers O.P., Orihuela C.J., Bijlsma J.J.

The main focus is on molecules against resistant strains of pneumococci, especially against strains of S. pneumoniae with different resistance patterns to penicillin [107,108]. Enter search terms to find related veterinary topics, multimedia and more. The roundworm Baylisascaris procyonis has been reported in rabbits. Streptococcus pneumoniae (known as pneumococcus) remains as the most common bacterial pathogen causing community-acquired lower respiratory tract infections and the leading cause of morbidity and mortality worldwide, contributing to more deaths than all other etiologies combined in 2016 (1.2 million deaths) [1,2,3,4]. Effective treatment has not been established. Reproductive disorders of rabbits include bacterial infections and metabolic disorders. McLaughlin R.F., Tyler W.S., Canada R.O.

As summarized by Hoover et al. Federal government websites often end in .gov or .mil. Careers, Unable to load your collection due to an error. Prevention is the same as for any other rabbit intestinal disease. For example, a rat model was used to detect infected pleural effusion by dosing complement activation product levels in pleural fluid of animals [83]. These animals were obtained from Sprague-Dawley rats in the 1950s and rederived to improve the health status of the animals. Among the studies focusing on pathogenesis, we observed that rat models are suitable to address lobar pneumococcal pneumonia, in particular on the role of impaired phagocytosis and on the detrimental effect of pneumolysin, which enhance pneumococcal virulence [78,79,80]. Therapies adjunctive to antibiotics such as systemic corticosteroids and gammaglobulins have also been tested in rat models, particularly in splenectomized rats with great success [93,94]. Roughage (hay or straw) should be fed during the treatment to help carry the hair fibers through the digestive tract and out with the feces. Later, they may become a bluish color, hence the common names blue bag and blue breasts. The doe will not eat but may crave water. Abgueguen P., Azoulay-Dupuis E., Noel V., Moine P., Rieux V., Fantin B., Bedos J.P. Amoxicillin is effective against penicillin-resistant Streptococcus pneumonia strains in a mouse pneumonia model simulating human, pharmacokinetics. Proliferative enteropathy caused by Lawsonia intracellularis bacteria may cause diarrhea in recently weaned rabbits. It occasionally affects adults and adolescent rabbits. Candiani G., Abbondi M., Borgonovi M., Williams R. Experimental lobar pneumonia due to penicillin-susceptible and penicillin-resistant Streptococcus pneumoniae in immunocompetent and neutropenic rats: Efficacy of penicillin and teicoplanin treatment. When infestation does occur, the rabbits are extremely itchy. No Impairment in hostdefense against Streptococcus pneumoniae in obese CPEfat/fat mice. The hair may fall out, and the area may become infected or infested with fly larvae (maggots). Streptococcus pneumoniae remains the most common bacterial pathogen causing lower respiratory tract infections and is a leading cause of morbidity and mortality worldwide, especially in children and the elderly. We found that IVIG improved survival of rabbits infected by each of the major epidemic clones of Hla- and PVL-producing community-associated MRSA, including the Rabbit models are also normally useful to assess different pneumococcal serotypes [18]. Because penicillin often causes diarrhea in rabbits, does treated with this antibiotic should be fed hay or some other high-fiber diet rather than a pelleted ration ( see Intestinal Diseases Intestinal Diseases Rabbits fed a suitable diet and kept in a healthy environment can live as long as 10 to 12 years. Activity of amoxicillin-clavulanate against penicillin-resistant Streptococcus pneumoniae in an experimental respiratory infection model in rats. Importance of CXC chemokine receptor 2 in alveolar neutrophil and exudate macrophage recruitment in response to pneumococcal lung infection. Investigation of Pre- and Post-Weaning Mortalities in Rabbits Chronic alcohol diets and IPe injections of 20% alcohol in saline were used to build a model of acute-on-chronic alcohol intoxication and study its effect on granulocyte response during pneumococcal pneumonia [75], showing reduced response due to impaired granulopoietic progenitor cell proliferation. Heavy breeds such as the Rex, Flemish Giant, and Checkered Giant are susceptible. Infection may cause signs of nervous system disease, such as loss of balance, tremors, and head tilt. Signs include hind end muscle weakness, paralysis, or inability to control urination or defecation. Strong association between capsular type and virulence for mice among human isolates of Streptococcus pneumoniae. Davis C.C., Mellencamp M.A., Preheim L.C. Ringworm is generally associated with poor sanitation, poor nutrition, and other environmental stressors. Bou Ghanem E.N., Clark S., Du X., Wu D., Camili A., Leong J.M., Meydani S.N. Rabbits that carry the fungus without showing any signs are very common. Siggins R.W., Melvan J.N., Welsh D.A., Bagby G.J., Nelson S., Zhang P. Alcohol suppresses the granulopoietic response to pulmonary Streptococcus pneumonia infection with enhancement of STAT3 signaling. However, the death rate among children younger than five years decreased by 57% since 2000, and the incidence of pneumonia decreased by 21% over the same time period [1]. Listeriosis, a bacterial infection of the blood that causes sudden death or abortion, is most common in does near the end of pregnancy. Serotype 19F generally carries low virulence [12] in immunocompetent mice; for this reason, to induce infection with this serotype, most of the studies have traditionally used immunodeficient animals [32]. Spence S. The Dutch-Belted rabbit: An alternative breed for developmental toxicity testing. Reducing stress (such as crowding) in young rabbits and feeding unlimited hay or straw help prevent the disease. Vaccination from 12 weeks of age is effective and Poor husbandry and stress may contribute to the disease. Your veterinarian can use laboratory tests to diagnose the disease. WebTyzzer disease , caused by Clostridium piliforme, is characterized by profuse watery diarrhea, anorexia, dehydration, lethargy, staining of the hindquarters, and death within This cancer is the primary reason for spaying (removing the ovaries and uterus) any nonbreeding female rabbits. NHPs models are, in our opinion, also suitable for studies on inoculation ad pathogenesis. The first sign of disease is conjunctivitis (inflammation of the eye) that rapidly becomes more severe and is accompanied by a milky discharge from the eye. Development of experimental respiratory infections in neutropenic rats with either penicillin-resistant Streptococcus pneumoniae or beta-lactamase-producing Haemophilus influenzae. Mracsko E., Stegemann-Koniszewski S., Na S.Y., Dalpke A., Bruder D., Lasitschka F., Veltkamp R. A Mouse Model of Post-Stroke Pneumonia Induced by Intra-Tracheal Inoculation with Streptococcus pneumoniae. To our knowledge, the potential application of PK profile or use of BAL in NHP models has not been evaluated. Cirrhosis is induced by administration of a hepatotoxin that causes cirrhosis and ascites [88]. Initially, the mammary glands become hot, reddened, and swollen. Because infected rabbits can spread the disease to humans and other animals, they should be isolated and treated. Generally, capsular serotypes 25 and 6B are highly virulent [12]. Rabbit calicivirus disease was confirmed in a group of 27 rabbits in Iowa in 2000. In addition, this review expanded the use of the different animal pneumococcal pneumonia models including relevant information about microbiological pneumococcal properties, mode of bacterial inoculation, pathogenesis, and the direct correlation with clinical disease as the one observed in humans. in 2017 [72], another method described to induce lung infection is direct intrabronchial instillation. The cause is typically Pasteurella bacteria, but other bacteria may be involved. Antibiotics seem to provide only temporary remission, and the next stress (such as giving birth to a litter) may cause relapse. In the IT challenge, the pathogen is directly delivered into the animals respiratory tree. Adults aren't the only ones at risk, Wanke-Jellinek L., Keegan J.W., Dolan J.W., Lederer J.A. Laboratory tests are required to distinguish between these diseases. To achieve infection, this procedure is carried out while the animal is under deep anesthesia, which suppresses gag and cough reflexes and allows inhalation. Tuvim M.J., Clement C.G., Huang E.S., Cote G.J., Evans S.E., Lei X., Deftos L.J., Gagel R.F., Dickey B.F. Deletion of the gene encoding calcitonin and calcitonin gene-related peptide does not affect the outcome of severe infection in mice. P <0.001. NHP studies on baboons (n = 15) confirmed that escalating doses of pneumococcal inoculation (serotype 19A-7) produce a host response ranging from spontaneous clearance of 106 CFU to severe pneumonia 109 CFU. Sohail I., Ghosh S., Mukundan S., Zelewski S., Khan M.N. Ershler W.B., Hebert J.C., Blow A.J., Granter S.R., Lynch J.

Sequestration and homing of bone marrow-derived lineage negative progenitor cells in the lung during pneumococcal pneumonia. Effect of bacterial pneumonia on lung simian immunodeficiency virus (SIV) replication in alcohol consuming SIV-infected rhesus macaques. Studies that specifically investigate the effect of aging on susceptibility to pneumococcal disease [31,40,41] compare aged mice (1926 months old) with young adults. Similar findings were seen in rhesus macaque models that develop similar respiratory symptoms, elevation of inflammatory biomarkes and pro-inflammatory cytokines in serum and BAL [133]. Luna C.M., Sibila O., Agusti C., Torres A. Wire cage bottoms should be brushed daily with a wire brush to help break the life cycle of the protozoa. In addition to therapeutic options, rat pneumococcal pneumonia models are also generally used to assess antipneumococcal vaccination efficacy and safety [95]. The outbred Swiss strains have also been widely utilized to build a neutropenic model and to allow evaluation of infection with less virulent pneumococcal serotypes and strains, such as 9, 14, 19F, and 23F. Infections can be caused by bacteria or viruses. The typical signs include inflammation of the reproductive tract and are usually seen in adults. Affected rabbits may have difficulty walking. The legacy of this great resource continues in the online and mobile app versions today. The trusted provider of veterinary information since 1955, Description and Physical Characteristics of Rabbits, Last review/revision Aug 2020 | Modified Oct 2022. Licensee MDPI, Basel, Switzerland. Thevaranjan N., Whelan F.J., Puchta A., Ashu E., Rossi L., Surette M.G., Bowdish D.M. The CO2 content in the aerosol promotes deep ventilation [30,68,69]. The seasonal incidence of the disease, signs (especially the swollen genitalia), and high death rate all help veterinarians make the diagnosis. This pneumococcal swine model is a valuable model for studies on colonization, transmission and development of vaccines and directed therapies against pneumococcus. Pneumonia in rabbits - Bunnyhugga In weaned rabbits 4 to 6 weeks old, diarrhea very similar to that described for enterotoxemia (see above) is seen. The site is secure. Rates and risk factors for recurrent pneumonia patients hospitalized with community-acquired pneumonia: Population-based prospective cohort study with 5 years of follow-up. Prevention Once treated, further It is caused by myxoma virus, a type of poxvirus. Community-acquired pneumonia. ASN100 improves survival in rabbit MRSA and MSSA pneumonia models. In addition, 50 mg/kg of linezolid could enhance rabbit survival to 80% (8/10) at 48 h and ultimately to 20% (2/10). Fur mites may cause mild skin irritation or inflammation in humans. Overall survival at 3 years also differed, with a survival rate of 96% (95% CI, 90 to 100) in the horse-ATG group as compared with 76% (95% CI, 61 to 95) in the rabbit The disease can progress to produce mental status changes, shock, and respiratory failure.
