Abstract

Twenty-five laying flocks suffered from drop in egg production ranging from 3-10% were examined bacteriologically and the following bacteria were isolated: E.coli (21.9%), Staphylococcus aureus (17.2%) Pseudomonas aeruginosa(11.3%), Proteus vulgaris (6.74%), Enterococci (5.61%), klebsiellaoxytoca (5.41%), proteus mirabilis (5.41%),klebsiella pneumoniae (5%); klebsiellaozaenae (5%), Yersiniaenterocolitica (4.18%), Salmonella (4.08%), Streptococcus (3.77%), Actinomycesbiogenes(3.06%), and Citrobacterfreundii (1.22%). Two hundred and fifteen (215) E.coli isolates were obtained and serotyped as 0166 (45 isolate), 018 (31 isolate), 078 (29 isolate), 01 (28 isolate), 086(17 isolate), o20 (14 isolate) and untypedE.coli strains (13 isolate). The pathogenicity of these serotypes were determined in 9 days old chicks, the E.coli 0166-infected chicks exhibited the higher morbidity and mortality (42.9% - 42.9%) followed by E.coli 078, E.coli 0146,E.coli 020, E.coli 01 and E.coli 086 respectively. Experimental infection of laying hens with E.coli 0166 resulted in a significant decrease in egg production from the first week post infection up to the fifth week (13.5 – 35%) followed by 018 and 078. vaccinated hens showed higher egg production, significant reduction in faecal shedding and egg contamination.
