The aim of the study was to determine co-occurrence of Marek's disease virus (MDV) and chicken parvovirus (ChPV) co-occurrence in field chicken flocks. The materials for the study derived from 115 broiler chickens or layer hens originated from 23 farms with suspicion of Marek's disease (MD). Dual infection with MDV and ChPV was found in 23 (20%) examined chickens. The results obtained suggest a...

In mammals, the type II melanoma antigen (Mage) protein family is constituted by at least 10 closely related members that are expressed in different tissues, including the nervous system. These proteins are believed to regulate cell cycle withdrawal, neuronal differentiation, and apoptosis. However, the analysis of their specific function has been complicated by functional redundancy. In accord...

Objective: Rice Bran Oil (RBO) is extracted from the outer layer of rice. Little information is available regarding its safety. The present study was conducted to assess its safety in chicken embryo model. Materials and Methods: RBO was injected on day 4 of incubation of chickens. The tissues and serum samples were collected. Oxidative stress parameters in the liver, kidney and brain and bioche...

  Egg drop syndrome (EDS) is caused by a hemagglutinating adenovirus which has become a major cause of lost egg production and sever economic losses in breeder and layer chicken flocks throughout the world. A PCR assay was optimized for detection of EDS virus in inoculated allantoic fluids (AFs) of duck and chicken emberyonated eggs. Two strains of EDS viruses were propagated in allantoic cavit...

The mucus layer plays an important role as an intermediate for the protection of the gut against acidic chyme, digestive enzymes, and pathogens; in addition, it acts as a lubricant and facilitator of nutrient transportation. Phytogenic compounds seem to promote intestinal mucus production. OBJECTIVES: The current study was conducted to investigate the effects of low and high levels of energy an...

avian influenza is a contagious viral disease affecting the respiratory, digestive and nervous system of birds belong to orthomyxovirus family. in the chicken mx gene, type of amino acid at position 631 determines the antiviral activity against influenza and vesicular stomatitis virus. a single nucleotide polymorphism (snp) at position 2032, responsible for the variation of amino acid at positi...
