Chickens are a major source of protein worldwide, yet infectious diseases continue to threaten the poultry industry. Avian pathogenic Escherichia coli (APEC), a subgroup of extraintestinal pathogenic E. coli (ExPEC), causes colibacillosis in chickens resulting in economic loss because of treatment, condemnation of products, and death. In this study, we evaluated a recombinant antigens (rAg) vac...

Few studies have been made of the blood proteins of tumor-bearing animals. Sanders, Huddleson and Schaible (8) studied the pooled serum of chickens infected with various types of fowl leukosis, and Sharp, Taylor, Beard and Beard (9) the serum of papillomatous rabbits. Changes in the serum proteins were found by both groups of investigators. In the present investigation the Tiselius method (11) ...

Poultry farms in Central Argentina are often infested by Mus musculus L., despite the regular application of the rodenticide bromadiolone. This failure may be explained by the consumption pattern of mice, which may prefer alternative foods available on the farms to bromadiolone baits. Here we examine the consumption pattern of bromadiolone in the presence of wheat by M. musculus infesting poult...

Aim. To determine the difference in immune responses of harderian gland clinically healthy chickens and ones with infectious bronchitis based on content, localization morphometric estimation surface markers ?- ?-lymphocytes to differentiation index as an indicator assessing body defenses. Methods. Histological, immunohistochemical, optical, statistical. Results. The histological study determine...

This study examined the adjuvant effects of dimethyl dioctadecyl ammonium bromide (DDA), CpG oligodeoxynucleotides (CpG-ODN), and chicken interferon-gamma (ChIFN-gamma) on a DNA vaccine (pcDNA-VP243) against the infectious bursal disease virus (IBDV). A plasmid encoding chicken IFN-ã was constructed. Twice at 2-week intervals, two-week-old chickens were injected intramuscularly and intraperiton...

BACKGROUND Glucocorticoid has an important effect on lipid metabolism in muscles, and the type of fatty acid likely affects mitochondrial utilization. Therefore, we hypothesize that the different fatty acid types treatment may affect the glucocorticoid induction of intramuscular lipid accumulation. METHODOLOGY/PRINCIPAL FINDINGS The effect of dexamethasone (DEX) on fatty acid metabolism and s...

Campylobacter jejuni/coli infections are the leading cause of bacterial diarrheal illnesses in humans. Many epidemiological studies indicate that improperly prepared meat from chickens that carry a high load of Campylobacter in their intestinal tracts is the key source of human infections. LAB, mainly members of the Lactococcus and Lactobacillus genera, increasingly have been tested as vehicles...
