Recall for E. coli contamination: about 100,00 pounds of frozen hamburger patties which were produced between April and May 2006 by Richwood Meat. The recalled beef is found in hamburger patties and ground beef sold under the brands Fireriver, Chef's Pride, Ritz Food, Blackwood Farms, California Pacific Associates, C&C Distributing, Golbon and Richwood. The strain has not yet been identified. Besides sickening and sometimes killing humans, E. coli can kill ferrets (including BFFs), especially the nastier strains of the bacterium, and at least some strains can cause permanent kidney damage in a large portion of surviving ferrets. Examples of some of the existing studies: BEGIN QUOTES Woods, J.B., C.K. Schmitt, S.C. Darnell, K.C. Meysick, and A. O'Brien (2002). Ferrets as a model system for renal disease secondary to intestinal infection with Escherichia coli O157:H7 and other Shiga toxin-producing E. coli. Journal of Infectious Diseases 185(4): 550-554. ISSN: 0022-1899. NAL Call Number: 448.8 J821 Abstract: Ferrets were evaluated as a possible small animal model for the development of colitis and/or signs of the hemolytic uremic syndrome after oral infection with Escherichia coli O157:H7 or other Shiga toxin--producing E. coli (STEC). Ferrets treated with streptomycin (Stm) had higher counts of E. coli O157:H7 strain 86-24 Stm-resistant (Stm(r)) or O91:H21 strain B2F1 Stm(r) in their stools than non--Stm-treated animals. None of the animals displayed evidence of colitis, but Stm- treated animals fed strain 86-24 Stm(r) exhibited weight loss significantly greater than that exhibited by ferrets fed an isogenic mutant negative for the adhesin intimin. Moreover, 11 (23%) of the 47 Stm-treated ferrets inoculated with 86-24 Stm(r) or B2F1 Stm(r) developed hematuria and/or histological damage to glomeruli or thrombocytopenia, compared with 0 of 14 uninfected control animals receiving Stm in water. Thus, the ferret may serve as a model for renal disease secondary to intestinal infection with STEC.

Characterization of hemolytic Escherichia coli strains in ferrets: recognition of candidate virulence factor CNF1. Marini RP, Taylor NS, Liang AY, Knox KA, Pena JA, Schauer DB, Fox JG. Division of Comparative Medicine, Massachusetts Institute of Technology, Cambridge, MA 02139, USA. Diseases associated with Escherichia coli infection are the subject of renewed interest due to emerging conditions such as hemolytic uremia syndrome. A collection of 15 strains of beta-hemolytic E. coli was isolated from diarrheic feces and diseased tissues of ferrets. All 15 strains were positive in specific PCR assays for the presence of hlyA, pap1, and cnf1. Seven of the cnf1-positive isolates were tested and shown to have a cytopathic effect on HeLa cell monolayers. The pathogenesis of these strains warrants future study.

Department of Veterinary Science and Microbiology, The University of Arizona, Tucson 85705, USA. [log in to unmask] Enterotoxigenic Escherichia coli with genes for heat stabile toxins Sta and STb was isolated from the gastrointestinal tract and multiple visceral organs of three adult and three juvenile black-footed ferrets (Mustela nigripes) that died in a captive breeding colony between 24 May 1998 and 2 July 1998. Similar isolates were obtained from rectal swabs of one adult and one juvenile that were clinically ill. All were fed a diet composed of mink chow, raw rabbit meat, beef liver powder, blood meal and lard. Escherichia coli of the same toxin genotype was isolated from the mixed ration. Clinical signs included sudden death, dehydration, anorexia and diarrhea. Necropsy lesions included acute enteritis with large numbers of rod shaped bacteria microscopically visible on intestinal villi.
