Infection of young turkeys with Plasmodium durae produced a significant increase in the mean relative right ventricular mass from 0.172 in the controls to 0.208 in the infected group. Although turkeys react less strongly to hypoxia than broiler chickens, the similarity of this finding to that previously reported in broilers infected with Aegyptianella pullorum suggests that the hypoxic effect o...

Methods The PCR-based detection technique for five Salmonella species was tested under O.I.E. requirements, to determine specificity, sensitivity, and repeatability. Primers were calculated by OLIGO software and produced with HPLC purification. Amplification was conducted by a T3000 Biometra PCR-machine. Testing was performed on a panel of five basic agents: Salmonella enterica ser. Enteritidis...

Salmonella pullorum (SP) is well adapted to cause an acute systemic infection in hens with a high mortality rate. This study aimed assess the efficacy and safety of salmonella-immune lymphokine (SILK) produced by hyperimmunized pullets during layer hens' production stage boost their immune response against infection. In this study, two groups 25 were used produce lymphokines; first group receiv...

An asd-deleted (Deltaasd) mutant of Salmonella enterica serovar Pullorum (SP) was constructed using an improved method of gene knockout by combining the pi-suicide plasmid system with the Red Disruption system. The asd gene was efficiently knocked out by the recombinant suicide vector, which replaced the asd gene with the CmR gene. Based on the balanced lethal host-vector system, the phenotype ...
