The reservoir of most of these fungi is the soil, however, making infection unlikely in a research facility. 110 Measles virus. Jills develop immunity to rotavirus infection, and subsequent litters are protected. Gross findings include a segmented, thickened lower bowel, usually the terminal colon but occasionally including the ileum and rectum (Fox et al., 1982; Fox, 1998a). Available commercial diets are certainly capable of supporting growth, reproduction, and maintenance in conventional settings. Ctenocephalides species can infest ferrets. Coburn D.R., Morris J.A. Death occurs in 1216 days from ferret strains of CDV and up to 35 days with canine strains.

The employee could opt for a cash buy out if it makes sense for the agency to do so once advanced sick leave has been determined to qualify for liquidation. The ferret was not recognized as having potential as an animal model for biomedical research until the 1900s. In: Fox J.G., editor.

Ferrets infected with ADV as adults develop persistent infection but rarely disease, although chronic progressive weight loss, cachexia, malaise, and melena have been described (Porter et al., 1982). In a study to determine the minimum oral dose of ivermectin needed for monthly heartworm prophylaxis in ferrets, the use of an antigen test (Uni-Tec Canine Heartworm test, Pitman-Moore Co., Mundelein, Illinois) detected infection in more untreated control animals than did the modified Knott test for detection of circulating microfilaria in the same ferrets (Supakorndej et al., 1992).

First, FERS provides annuity benefits, similar to private sector pension bene-fits, that are based on an employee's years of postal/federal service. The ease with which estrus is detected in the ferret, as well as the size of the ferret and ease of its maintenance in captivity have made the ferret a model for study of neuroendocrine events and their gonadal correlates. The diet should contain approximately 30% fat and 40% protein. Congenital defects identified in ferrets include a variety of neural tube defects, gastroschisis, cleft palate, amelia, corneal dermoids, cataracts, and supernumerary incisors (Willis and Barrow, 1971; Ryland and Gorham, 1978; McLain et al., 1985; Besch-Williford, 1987). 146, 296 A serious health condition involving incapacitation that requires prenatal care qualifies as a reason for receiving sick leave.

Most reports of tuberculosis in ferrets are in animals that were used for research in England and the rest of Europe between the years of 1929 to 1953 and were likely related to the feeding of raw poultry, raw meat, and unpasteurized milk to ferrets during this time (Fox, 1998a). One major supplier of ferrets uses sunken tubs filled with bedding to promote a sense of security and isolation of the jill. ). Three species of the genera Isospora and Eimeria have been reported to infect the ferret: Isospora laidlawi, Eimeria furonis, and E. ictidea (Blankenship-Paris et al., 1993). 452 1432 | 702 Isolation of C. perfringens type A from gastric and small-intestinal contents is required.
