Abstract
Background: Zoonotic Yersinia infection has been previously reported in humans and animal hosts in Nigeria, occasionally with fulminant disease. Despite earlier evidence of Yersinia pathogen circulating in human and animal populations in Nigeria, studies and suspicion index to Yersinia is below an acceptable average amongst clinicians, diagnosticians, academics and health policy officers. Methods: The Deoxycholate Citrate Agar (DCA) was used as selective media to culture Yersinia preceded by inoculation in MacConkay agar. Plates with evident growth in the differential media consistent with reported accounts for Yersinia were picked and inoculated in selective medium and left for 48 hours until growth was seen, other samples left until five days before being discarded as negative. Pure cultures were subjected to comprehensive biochemical tests standard and previously applied for diagnosis and discrimination of Yersinia species. Result: This research recorded an overall microbial prevalence of 30%. Prevalence of Yersinia enterocolitica was 18.3% and Y. pseudotuberculosis 11.7%. Male dogs presented a relative prevalence of Y.
