Abstract
A study was carried out to determine the bacterial flora in dead in shell embryos from commercial quail
hatcheries operating in Namakkal, Tamil Nadu. Among one hundred and twenty quail eggs failed to hatch
at termination of incubation were collected, 58 isolates of bacteria comprising of Escherichia coli (29),
Klebsiella spp (14 ), Staphylococcus spp (10), Salmonella spp (5) were cultured. The incubation period of
Japanese quail eggs to hatch is 18 days. The level of bacterial contamination in quail eggs failing to hatch
at 18th day of incubation was 70%. The antibiotic sensitivity pattern revealed that highest sensitivity were
seen to Chloramphenicol (82.7%), Amoxycillin (70.6), Ciprofloxacin (60.3) and Gentamicin (48.27%) but were
quite resistant to Oxytetracycline, Lincomycin and Co-trimaxazole.
