Microbact 24E detection and prevalence of faecal enterobacteriaceae isolates from lactating cattle in Jos-Plateau and environs, Nigeria

Abstract

Species of the family Enterobacteriaceae lead to illnesses affecting humans and animals globally and is a serious public health problem worldwide especially in developing countries. A cross-sectional study was conducted to assess the prevalence and distribution of faecal Enterobacteriaceae isolates from lactating cattle in Jos-Plateau and environs, Nigeria, between March 2017 and May 2018. Microbact
24E kit system biochemical test was used to detect faecal Enterobacteriaceae isolates from 452 lactating cattle across six Local Governments Areas (LGAs). Data analyses were done using Microsoft Excel 2013 and Minitab 17 statistical package. Eighteen faecal Enterobacteriaceae isolates were isolated out of 452 samples examined, and of the eighteen, only eleven samples were confirmed
with the following species, Salmonella subsp. II (Salmonella salamae) (1, 0.22%), Salmonella subsp. IV (Salmonella houtenae) (1, 0.22%), Proteus frontium (1, 0.22%), Proteus mirabilis (1, 0.22%), Citrobacter spp. II (2, 0.44%), Enterobacter agglomerans (2, 0.44%), Escherichia fergusonii (1, 0.22%) and Trabulsiella guamensis (2, 0.44%). The prevalence and relative frequency of distribution of Enterobacteriaceae isolates were highest in Jos North (5, 6.67%) followed by Jos South (2, 2.67%), and the lowest were in the four other local governments. The overall prevalence of faecal Enterobacteriaceae in Jos-Plateau and environs (11, 2.43 % at 95% CI). The study concludes that the
presence of faecal Enterobacteriaceae isolates in lactating cattle in the Jos-Plateau and environs may pose public health concerns, and therefore, calls for continuous surveillance to avoid the outbreak of bacterial zoonosis
