Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine that plays an important role in host defense against a variety of microorganisms including protozoan parasites. Interestingly, some microbial pathogens also express a MIF-like protein, although its role in disease pathogenesis is not well understood. The aim of this study was to compare an Eimeria-encoded MIF (E.MIF) pro...

Multiplication-stimulating activity (MSA) is the name given to a family of polypeptides with a molecular weight of approximately 10,000 that have been isolated from the culture medium of a rat liver cell line. MSA stimulates growth and DNA synthesis in chick embryo fibroblasts and has weak insulin-like metabolic activity. We have purified MSA and characterized the binding of ‘““I-labeled MSA to...

The purpose of this study was to determine the effect watermelon seed flour supplementation in feed on interior quality native chicken eggs. This research is a biological using Completely Randomized Design (CRD) with 4 treatments and 5 replications. Each treatment used chickens. results statistical analysis showed that had very significant (p<0.01) egg yolk index white height an insignifican...

A total of 22 Salmonella enterica serotype Enteritidis (S. Enteritidis) strains isolated from human and chicken were subjected to DNA fingerprinting by repetitive sequence PCR using ERIC and BOX primers, antibiotic resistance and plasmid patterns. Both ERIC and BOX PCR amplification data revealed a highly genetic homogeneity between isolates from human and chicken except one isolate, which orig...

BACKGROUND Despite of the advances in infectious diseases prevention and food technology, food-borne diseases are considered major problems in developed and developing countries. Meat plays a key role in transferring zoonotic diseases to human. OBJECTIVES This study was conducted in south of Tehran, Iran, to investigate the prevalence rate of Salmonella spp. in packed and unpacked red meat an...

Two intestinal spirochete isolates obtained from chickens with diarrhea were examined by electron microscopy, biochemical tests, rRNA gene restriction pattern analysis, and multilocus enzyme electrophoresis. One isolate (strain 91-1207/C1) was pathogenicity tested in vivo in chickens. The chicken spirochetes were morphologically indistinguishable from Serpulina innocens and Serpulina hyodysente...

Background Broiler chickens have properties as meat-producing poultry and produce meat with soft fiber quality. Broiler’s embryo needs to be given attention, especially against disease. The purpose of the study was observe trend research topic external factors which could affect embryo’s growth broiler. Method<ns4:b...

Coronavirus host and cell specificities are determined by specific interactions between the viral spike (S) protein and host cell receptor(s). Avian coronavirus infectious bronchitis (IBV) has been adapted to embryonated chicken eggs, primary chicken kidney (CK) cells, monkey kidney cell line Vero, and other human and animal cells. Here we report that acquisition of the cell-cell fusion activit...
