Abstract

E. coli infection is a very common problem encountered among newly hatched chicken in Bangladesh. The aim of present study was to detect and characterize E. coli in the gut, liver and lungs of Day-Old Chicks (DOC). Total viable count (TVC) in gut, liver and lung was the highest among “C” grade chicks compared to those of “A” and “B” grade chicks. The isolated E. coli were sensitive to Enrofloxacin and Ciprofloxacin but resistant to Cloxacillin, Nalidixic acid and Erythromycin. The result indicated that load of E. coli was higher among the lower grade chicks.
