Bacteria Associated With Avian Cellulitis In Broiler Chickens

Abstract

This study was carried out on 100 broiler chickens, which showed gross lesions of cellulites. The birds were collected from different farms in Khartoum and Khartoum North. Samples from the birds were cultured on blood agar and Mac Conkey’s agar media and incubated for 24 hours at 37 °C. The main isolated were Escherichia coli (ninety six percent) of the samples showed growth of E.coli, mixed with other bacterial isolates mainly Strepto cocci, Proteus vulgaris, Streptococcus spp. Bacillus spp. and different species of Staphylococcus. About 4% of the samples showed no growth when cultured, this an indication that the cellulitis might not be caused only by bacteria. Most of lesions in samples that have been observed were in inner aspect of the thigh muscles and other lesions were in wings , breast near keel bone, some in back and flank region. The coagulase (+ve) Staph. spp. , which were isolated were Staph. delpheni, Staph.aureus, Staph. intermeduis.
