A total of 184 tracheas, 147 livers, 150 spleens and 148 hearts from apparently healthy and dead chickens were sampled and the bacterial flora was determined. The bacteria most commonly cultured from these four organs of healthy birds were Staphylococcus spp., Streptococcus spp., and Escherichia coli. Escherichia coli, Aeromonas spp., Staphylococcus spp., Proteus spp., and Citrobacter spp., were the common isolates from dead chickens. Pasteurella haemolytica was present in small numbers in the trachea, liver and spleen of healthy chickens and liver, spleen and heart of dead chickens.
