Abstract:
An outbreak of salmonellosis was recorded in captive pygmy hogs (Sus salvanius), a critically endangered species of mammal. Of 42 captive animals maintained for conservation breeding by the Pygmy Hog Conservation Programme, Guwahati, Assam, India, 7 (16.67%) died within 3 days. The organism associated with this outbreak was identified as Salmonella enteritidis. The organisms were highly susceptible to chloramphenicol, gentamicin, norfloxacin and cefotaxim but were resistant to ampicillin, oxytetracycline, mezlocillin and sulfamerazin. The strain belonged to phage type 13a/7 and harboured two plasmids (38 and 44 megadaltons). The organisms were enterotoxigenic in CHO cell assay and were found to carry stn, sef and pef genes.
