“…was studied comprehensively by several researchers. It was reported that probiotics maintained or increased the normal intestinal flora which are normally found in the intestinal tract of hatched birds and these flora can exclude Salmonellae colonization (Goren et al, 1988;Starvic 1992;Barbour et al, 1993;Nisbet et al, 1996;Mead 2000;Seo et al, 2000). Seuna et al, (1980) who found that supplementation of the birds with normal avian gut microflora didn't prevent or only partially prevent Salmonella colonization.…”

This study was carried out to investigate the efficacy of the locally prepared autogenous Salmonella Enteritidis (S. Enteritidis) bacterin as well as a probiotic preparation in the prevention of broiler chickens from S. Enteritidis infection. A total of three hundred and ten, one day-old Hubbard broiler chicks were used. At day old, ten chicks were sacrificed and examined bacteriologically to prove their freedom from S. Enteritidis infection. Three hundred birds were divided into four equal groups. Chickens in group (1) were kept as blank control negative non infected-non treated birds, while those of group (2) were challenged non treated birds. Group (3) was vaccinated intramuscularly by the autogenous bacterin at the first day of age in a dose of 0.2 ml/bird and boostered as a second dose at 10 days of age in a dose 0.5 ml/bird, however, group (4) was given a commercial probiotic preparation as 1gm/ 4 liter of the drinking water from the first day of age and continued for 5 successive days. All birds in groups 2, 3, and 4 were challenged orally by 0.5 ml containing 10 9 CFU/ml S. Enteritidis at 20 days of age. All the groups were kept under complete observation for three weeks for recording signs, moralities, gross lesions, shedding rate of S. Enteritidis, re-isolation of the organism, the performance as well as detection of the titer of antibodies serologically using microagglutination test and enzyme linked immunosorbant assay (ELISA) test. The results showed that the both the bacterin and the probiotic are equally effective in reducing signs, mortalities, gross lesions, the shedding rate and the re-isolation of S. Enteritidis and also increasing in the performance of chickens. The effect of the bacterin and the probiotic was significant (P≤0.05) when compared with the infected non treated chickens. Moreover, the serological investigation revealed an improvement in the titer of antibodies after vaccination and probiotic treatment. In conclusion, double doses of locally prepared autogenous S. Enteritidis bacterin and the probiotic preparation were effective and safe methods for prevention of S. Enteritidis infection in broiler chickens.

“…Subsequently, Goren et al (1984bGoren et al ( , 1988 developed a method of spray application to treat newly hatched chicks in the hatchery, either in the hatchers themselves or in delivery boxes. Spraying in the hatcher followed by drinking water administration on the farm was used by Blankenship et al (1993) and shown to be effective in controlling Salmonella infection, but there is no evidence that a double treatment of this kind is necessary to obtain maximum protection.…”

“…For example, island birds might face an immunobiome that is quantitatively or qualitatively different from the one faced by continental birds (Matson 2006;Horrocks et al 2011). However, for this to drive the observed pattern, the difference would have to exert comparable genetic effects (e.g., selection pressures) on both immunological indexes or impose systematic effects on pre-or neonatal phenotypes (e.g., via mothers [Grindstaff 2008] or directly [Goren et al 1988]). Because the typically stable index of agglutination is also substantially elevated, it is more challenging to envision a scenario in which the population differences in both immunological indexes are solely the consequence of an infection with a disease-causing organism (i.e., a result of an acute-phase response).…”

Island organisms face a range of extrinsic threats to their characteristically small populations. Certain biological differences between island and continental organisms have the potential to exacerbate these threats. Understanding how island birds differ from their continental relatives may provide insight into population viability and serve as a predictive tool for conservation efforts. We compared an eastern bluebird population in Ohio with a threatened population in Bermuda in terms of the birds' development, morphology, immunology, and reproduction. These comparisons revealed that island nestlings had shorter wings and island adults had longer wings than their continental analogs. Island nestlings also had shorter tarsi than continental nestlings at day 8 posthatch, but this difference was absent at day 15 and in adults. Adults weighed less in Bermuda than in Ohio, and both nestlings and adults in Bermuda exhibited higher levels of two immunological indexes (concentrations of an acute-phase protein and titers of nonspecific antibodies). Clutch sizes and hatch rates did not differ between the island and continental populations; however, as the breeding season progressed, brood sizes declined in Bermuda, whereas no such decline occurred in Ohio. Despite these differences and differences in nestling development, island and continental parents fed their nestlings at equal rates. Overall, our results suggest that the Bermuda phenotype may be adjusted to certain aspects of the island environment but not to others. Efforts to conserve the bluebirds of Bermuda may be improved by focusing on the intraseasonal patterns in nestling mortality and, more generally, the survival probabilities of different age classes.
