Abstract


This research was aimed at determining the antibiotic resistance pattern of enterobacteriaceae and molecular characterization of Escherichia coli isolates from Abattoir waste water in Jos metropolis. A total of 30 samples from slaughter slab and drainage were examined, findings of this work show that the bacterial load of slaughter slab and drainage was 4.5 x 1010 cfu/ml and 1.6x1010 cfu/ml respectively; while the coliform count of slaughter slab waste water and drainage wastewater was 131/100ml and 114/100ml respectively. Nine species of enterobacteriaceae were isolated; Escherichia coli 30 (22%) Klebsiella sp 16(12%). Salmonella sp 24(18%), Enterobacter sp 18(13%), Citrobacter sp 6(4%) Shigella sp 9(7%), Yersinia sp 9(7%), Proteus sp 17(12%) and Serrettia sp 3(2%). The isolates were resistant to more than three (3) antibiotic, hence exhibited muti-drug resistance patterns. Ten of the Escherichia coli isolates were confirmed by molecular methods and one possessed the shiga toxin stx-1 gene. The
results obtained from these findings imply that waste water from Jos abattoir harbours many pathogenic bacteria, which are highly resistant to commonly used antibiotics.
