Abstract:
... Twenty-four strains of Salmonella enteritidis, isolated from several outbreaks of salmonellosis from different poultry farms in India, were checked for the plasmid profile and detection of virulence gene(s) by PCR. Most of the strains contained only a single plasmid of 55 kb. Additional plasmids of 23.2 kb and 8.7 kb were seen in one of the strains, and another strain carried only two plasmids of ...

Abstract:
... White Leghorn chickens from a nonselected closed population were typed for two RFLP located in the 3' end of the gene coding for cytosolic phosphoenolpyruvate carboxykinase (PEPCK-C), a major control gene of gluconeogenesis. The two RFLP gave rise to three alleles (or haplotype classes), thus defining six genotypes. Feed efficiency (FE) and residual feed consumption (RFC) varied significantly amon ...

Abstract:
... In 1998, novel strains of infectious bronchitis virus (IBV) were identified in chickens from the southeastern United States and classified as a new serotype designated Georgia 98 (GA98). Because of the widespread nature of the GA98 virus in the southeastern United States and the lack of adequate protection with the DE072 vaccine, we developed a specific vaccine for the GA98 serotype. The GA98/0470 ...

The 0.5-kb cDNA encodes a 106 amino acid protein with a cysteine spacing pattern suggesting that HEP21 is a new member of the uPAR/CD59/Ly-6/snake neurotoxin superfamily. The closest homology of HEP21 is to mouse Ly-6C. Unlike most members of ...
