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...

Pathogens of veterinary and medical importance were investigated in 240 feral pigeons (Columba livia) captured in warehouses in São Paulo State, Brazil for one year. Rapid serum agglutination test (RST) was performed for the detection of antibodies against Mycoplasma synoviae, Mycoplasma gallisepticum and Salmonella Pullorum/ Gallinarum. Positive samples were submitted to hemagglutination inhib...

The study was designed to investigate the prevalence and antibiotic resistance profile of Salmonella spp. in broiler chicken meat sold in the Karachi City-Pakistan. A total of 160 meat samples were randomly collected from different retail markets and examined for the presence of various species of salmonella. The prevalence rate recorded was 48.75%. Different species of salmonella detected were...

Salmonellosis is a major public health problem throughout the world. Thus, there is a huge need for diversified control strategies for Salmonella infections. In this work, we have assessed the potential use of Bacillus subtilis (B. subtilis) spores for the expression of a major protective antigen of Salmonella serovar Pullorum, OmpC. The expression of OmpC on the surface of spores was determine...

Introducción: La tifosis aviar y la pulorosis, enfermedades ocasionadas por Salmonella enterica subsp. serotipo Gallinarum biotipo Pullorum respectivamente, son responsables de una elevada mortalidad en aves corral generando grandes pérdidas económicas para los avicultores. Objetivo: Fortalecer detección agentes causales pulorosis mediante optimización técnicas moleculares, tales como PCR punto...

The pathology of pullorum disease has been frequently described, but little information exists concerning the mechanism by which Salmonella pullorum exerts a damaging effect on its host. While the organism becomes quite generally distributed throughout the chick during the course of disease, the fact that it tends to be prevalent in the liver suggests the possibility of. alterations in both pro...
