The accumulation and transfer of Pb, Zn, Cu, and Cd along a soil-plant-insect-chicken food chain at contaminated sites were investigated. The study site nearing the Pb/Zn mine had been contaminated by heavy metals severely. Cadmium and Pb concentrations steadily declined with increasing trophic level (p < 0.01), but concentrations of Zn and Cu slightly increased from plant to insect larva (p > ...

In a case-control study of Campylobacter spp. risk factors in England during 2005-2006, we identified recent consumption of commercially prepared chicken as an important risk factor. The risk for illness associated with recent chicken consumption was much lower for persons who regularly ate chicken than in those who did not, which suggests that partial immunologic protection may follow regular ...

The data herein is related to the research article entitled "Functional analyses of the interaction of chicken interleukin 23 subunit p19 with IL-12 subunit p40 to form the IL-23 complex" [1] where we demonstrated that the chicken interleukin (IL)-23α, IL-12p40, and IL-23 complex regulates Th1, Th17, and Treg cytokine production through heterodimer receptors as well as a homodimer receptor cons...

Chicken embryo fibroblasts secrete a 72 kDa progelatinase that displays all of the characteristics of a matrix metalloproteinase. Employing reverse-transcription PCR and degenerate oligonucleotide primers that are specific for two highly conserved sequences found in all matrix metalloproteinases, a DNA fragment specific for the chicken gelatinase was generated. Using this PCR product as a probe...

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...

data collected in 2012 on 400 chickens were subjected to two-way analyses of variance to estimatebody weight, morphometric traits as well as the correlationbetween body weight and morphometric traitsin isa brown and ilorin ecotypechickens. the studied morphometric traits were comb length, beak length,head length, neck length, body length, wing length, shank length, thigh length, toe length, bre...

objective: fungal agents cause disease in virtually any susceptible hosts. in the poultry production and medicine, pathogens were eliminated from a line of a breeder by injection of antifungals into hatching eggs. there is little information available describing the safety of the antifungal drugs on the birds embryonated eggs. the objective of this study was to investigate the efficiency of the...

background biosurfactants are surface-active compounds produced by some microorganisms. objectives in this study, we collected surface skin samples from breast of poultry (chicken, turkey, and, quail) and screened for biosurfactant-producing bacteria. we also determined the genera of cultured strains. materials and methods 33 hemolytic bacterial strains (15, 11, and 7 isolates from chicken, tur...
