Abstract
The present study was reflected on the prevalence of salmonella antibodies in
breeder chicken and salmonella isolates from eggs at different stage. Eggs are
collected from the selected Hatchery at different stages (at laying period, prior to
incubation at hatchery, and the stage of incubation at 7 days, 14 days, for the
isolation of Salmonella Spp. The prevalence of Salmonella antibodies were also
determined from selected flocks by Rapid Serum Plate Agglutination test
(RSPAT) using Salmonella Nobilis antigen. A total of 225 sera samples were
tested by Rapid Serum Plate Agglutination (RSAPT) test to determine the
prevalence of Salmonella antibodies in breeder chicken .The prevalence of
Salmonella antibodies was 20% in group A, 24% in group B, and 28% in group
C. The prevalence was highest recorded in group C (28%) followed by group B,
(24%) and group A, (20%). An investigation was conducted on hatchery samples
for the isolation of Salmonella spp. from eggs (Yolk interior, egg shell
membrane). Salmonella organism were recorded from 33 of 100 (33%), 3 of
100(3%), samples of yolk interior, egg shell membrane.
Description
The importance of salmonellosis in poultry sector has increased to be a growing
concern day by day through the world during the last decades. The etiologic agents
are responsible for various pathogenic process in man and animals including
poultry (Freeman, 1985). Since the direct or indirect losses due to this type of
infectious agent are estimated undoubtedly very high, therefore the research for
the epidemiology of infection, reservoir of salmonella infection and economic
losses .The importance continue to be of increasing interest to the bacteriologist
and epidemiologist all over the world
