laboratory rabbit strains

53 W. Jackson Blvd., Suite 1552 However, about 200 inbred strains of rats have been described, with about a dozen strains being commercially available in the USA, Europe and Japan. Viral hemorrhagic disease is found in almost every country that raises rabbits except the USA. Where there is a choice, the use of isogenic strains is strongly recommended. A few outbreaks have been reported in the USA since 1930. At that time P. B. Sawin took a chinchilla stock of unknown origin with him to the Bussey Institute. Large, eosinophilic, cytoplasmic inclusion bodies in the conjunctival epithelial cells are also helpful in diagnosis. Rabbit breeds vary greatly in size and For example, it is 18.5 days in C57BL/6J (000664) mice, 20 days in BALB/cJ (000651) mice, and 21 days in A/J Inbred strains are also available, but are not as commonly used as inbred mice. The causative virus is closely related to vaccinia virus, and some outbreaks may have been caused by a virulent strain of vaccinia. Rabbit Council but the New Zealand White (NZW), bred in the 1920s has become the one most commonly used in … The trusted provider of veterinary information since 1955, Bacterial and Mycotic Diseases of Rabbits, Which of the following best indicates respiratory distress in a blue-headed parrot (, Last full review/revision Sep 2015 | Content last modified Oct 2015, © 2020 Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., Kenilworth, NJ, USA), © 2021 Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., Kenilworth, NJ, USA, Associate Professor of Zoological and Exotic Animal Medicine, Department of Small Animal Medicine &and Surgery, College of Veterinary Medicine. Zoonoses Associated with Rabbits. Myxoma virus–infected Sylvilagus develop fibroma-like lesions similar to those caused by rabbit fibroma virus. The first report of the virus in the Western hemisphere was in Mexico City in 1988. The legacy of this great resource continues in the online and mobile app versions today. There is no treatment, but the infection appears to be self-limiting if susceptible rabbits are not continually introduced into the population. This site complies with the HONcode standard for trustworthy health information: verify here. A killed vaccine effectively reduced the incidence of rabbit calicivirus in Europe in the late 1980s. Common laboratory rabbit strains Rabbitpox is an acute, generalized disease of laboratory rabbits (Oryctolagus) that apparently has not been recognized in wild rabbits (Sylvilagus). Other common strains are the Sprague Dawley, Fischer 344, Holtzman albino strains, Long–Evans, and Lister black hooded rats. In the USA, myxomatosis is restricted largely to the coastal area of California and Oregon, where epidemics occur infrequently but sporadic cases are common. Lab. Fibromas may be found in domestic rabbits in areas where they are endemic in wild rabbits and where husbandry practices allow contact with arthropod vectors. Neither type of papillomatosis is treated, and the condition usually resolves spontaneously over time. Rabbit calicivirus disease is highly infectious in European rabbits (Oryctolagus), but cottontail rabbits and jackrabbits are not susceptible. This full life-cycle diet comes in a pelleted form and is a complete feed that requires no extra supplementation. Choice of Species and Strain Shope fibromas are found under natural conditions only in cottontails, although domestic rabbits can be infected by inoculation of virus-containing material. In rabbits that survive longer, subcutaneous edema and nodular skin tumors are seen. Because Shope fibromas are of little significance in domestic rabbits, no control measures have been developed. Sci. • Crossing several Wistar females with wild gray male. Myxomatosis has a worldwide distribution. Many congenital malformations have been observed in instances where inbreeding of rabbits has been practiced. Pox lesions may be present on the skin. Myxomatosis is a fatal disease of all breeds of domesticated rabbits caused by myxoma virus, a member of the poxvirus group. Rabbit, any of 29 species of long-eared mammals belonging to the family Leporidae, excluding hares (genus Lepus). People and other mammals are not affected. An attenuated vaccine prepared from a myxomatosis virus has protected rabbits infected under both field and laboratory conditions. The Veterinary Manual was first published in 1955 as a service to the community. Therefore, cessation of breeding for 4–6 wk seems to allow the disease to run its course, because seropositive does do not infect their offspring. These areas correspond to the geographic distribution of the California brush rabbit (S bachmani), the reservoir of the infection. The rabbit is the breed of choice for polyclonal antibody production, tools commonly used in a variety of research methodologies. Rabbits are commonly used for toxicity and safety testing of substances such as drugs, chemicals and medical devices. However, the collection of inbred strains of rabbits now held at The Jackson Laboratory, which is easily the largest collection of such material in the world, was not initiated until 1929. The eyelids, nose, lips, and ears become edematous, which gives a swollen appearance to the head. , 48, 52-6. A few outbreaks have been reported in the USA since 1930. The gestation period for laboratory mice is generally consistent within a strain but varies among strains from 18-21 days. We do not control or have responsibility for the content of any third-party site. laboratory rabbits. Two types of infectious papillomas occur infrequently in domestic rabbits. • Head and extremities - black or brown • Rest of the body - white with pigmented eyes … Once in the laboratory, rabbits used in research in spaces depending on their weight, according to recommendations made by The Guide for the Care and Use of Laboratory Animals. The Russian or Himalayan rabbit is white with black extremities. Rabbits differ from hares in size, life history, and preferred habitat. The causative virus is closely related to vaccinia virus, and some outbreaks may have been caused by a virulent strain of vaccinia. Environmental conditions such as housing and husbandry have a major impact on the laboratory animal throughout its life and will thereby influence the outcome of animal experiments ( Baumans 2004 ; Van de Weerd et al. They are used in skin and eye irritation studies, such as the archaic and painful Draize tests for cosmetics, personal care, household products and other chemicals. Transmission is through direct contact and there are carrier animals. Enteropathogenic strains of E coli (serotype O103) commonly express the eae gene, which codes for intimin, an outer membrane protein associated with the attaching and effacing lesions. Rabbits used in research who are suffering from pain and distress may display a number of signs including lack of appetite, weight loss, self-mutilation, aggression, tremoring and/or vocalization.
