The Effect of Baytril against Salmonella london Infection in Chickens Z. A. Al-Chalabi , A. Abdul-Aziz and N. R. Mahdi

Abstract

The purpose of this study was to obtain additional information regarding
the effectiveness of Enrofloxacin (Baytril®) against artificially induced
infection of S. london in chickens.
One hundred and sixty one day old chicks of mixed sex were divided
equally into two groups A (treated group) and B (control, infected non-treated
group). Chicks were reared on separated rooms on wood shavings litter, and
given water and irradiated feed continuously for 55 days. All chickens were
infected at 3 days with 4×105 S. london/ml in drinking water. The administration
of salmonella was followed by intestinal colonization, detected by isolation of
salmonella from cloacal swabs, caecal contents and quantitative numeration per
grams of caecal contents, weekly for 8 weeks.
Group A was treated with Enrofloxacin (Baytril®) 0.5 ml/L drinking water
on day 45 for 5 days. Twelve days after the end of the therapy the presence of
salmonella could not be detected by cloacal swabs and in caecal contents.
This suggests that Baytril seems to have a good efficiency in total
elimination of salmonella from the intestine of infected chickens.
