Abstract

The effectiveness of commercially available disinfectants was evaluated against Salmonellae isolated from different internal organs of 52 numbers of dead layer chickens in the district of Dinajpur during the period from July 2009 to June 2010. Bacterio-biochemical methods were used to isolate and identify the Salmonella organisms from 154 samples of liver, spleen, heart and lungs of birds, of which 36 (23.38%) samples had Salmonella infection. Organ-wise prevalence of Salmonella infection showed highest prevalence in liver ( 34.62%), followed by spleen (23.087%) , heart (20.00%) and lowest in lungs (4.00%). Effectiveness of disinfectants was tested at different concentration on Salmonella culture on SS agar media and measured by zone of inhibition incubated for 24 hours. Highest average zone of inhibition was recorded with Desinkap® (12.50 ± 2.08), followed by GPC (8) TM ® (11.33 ± 1.53) , and more or less similar patterns with TH 4 ® ( 10.50 ± 0.71), Virocid ® ( 10.50 ± 0.71) and Lysol ® ( 10.00 ± 0.00). It may be concluded from these results that Desinkap® is the most effective disinfectant against Salmonellae as it contains multiple ingredients.
