Cellulitis has emerged as an economically important disease of broiler chickens. The impact of environmental risk factors on the incidence of cellulitis has not been evaluated in the United States. Escherichia coli (E. coli), the causative agent, is introduced through skin scratches during the grow out. Our previous work suggested that the litter was an important reservoir for cellulitis-associ...

Campylobacter infection is the leading foodborne bacterial gastroenteritis worldwide and the bacteria are frequently isolated from the intestines of chickens. The broiler meat contamination with C. jejuni or C. coli may occur during slaughter processing. The aim of the study was to investigate the prevalence of Campylobacter in poultry flocks and the corresponding broiler carcasses in 15 distri...

  Avian Leukosis Virus Subgroup-J (ALV-J). Mycoplasma gallisepticum (MG) and MycopJasma synviae (MS) are important pathogens in chickens that cause severe economical losses in poultry industry throughout the world. Seven broiler grandparent flocks of Iran (six broiler strains) were sampled randomly at the ages of 8-63 wk (100 samples from each flock) for antibody detection to ALV-J, MG, and MS ...

Since 1998, an epidemic of avian influenza occurred in the Iranian poultry industry. The identified agent was a low-pathogenicity H9N2 avian influenza virus that caused frequent episodes of high mortality in broiler chicken farms in Iran and some other Asian countries. This study was designed to investigate the prevalence of AIV H9N2 subtype in commercial chicken flocks in Dezful, southern Iran...

A prospective cohort study was performed to evaluate the prevalences and loads of Salmonella and Campylobacter spp. in farm and processing plant samples collected from 55 commercial broiler chicken flocks. Environmental samples were collected from broiler houses within 48 h before slaughter, and carcass rinses were performed on birds from the same flocks at 4 different stages of processing. Sal...

The purpose of the present cross-sectional study was to evaluate the health status of organic broiler chickens and the contamination rate with Salmonella and Campylobacter in organic broiler production in Belgium. The broilers were screened for antibodies against routinely monitored poultry diseases at 1 day old and at slaughter. Fecal examination for the presence of worm eggs was done at slaug...

Commercial chickens in Jordan suffer from respiratory disease of undetermined etiology. This study was designed to document the involvement of Mycoplasma gallisepticum (MG) in this respiratory disease. Seventy six different chicken flocks with respiratory symptoms (48 broiler flocks, 21 layer flocks and 7 broiler-breeder flocks) were examined serologically by commercial MG ELISA kit and bacteri...

Infectious bronchitis virus (IBV) causes respiratory disease in chickens all over the world. Infectious bronchitis virus has many serotypes that do not confer cross protection against each other. The current study was designed to know which IBV types were circulating in Jordanian broiler chickens. Tracheal swabs from 175 broiler flocks at the acute phase of respiratory disease were collected. T...

Campylobacter successfully colonizes broiler chickens, but little is known about the longer term natural history of colonization, since most flocks are slaughtered at an immature age. In this study, the prevalence and genetic diversity of Campylobacter colonizing a single free-range broiler breeder flock was investigated over the course of a year. The age of the flock was the most important fac...

avian leukosis virus subgroup-j (alv-j). mycoplasma gallisepticum (mg) and mycopjasma synviae (ms) are important pathogens in chickens that cause severe economical losses in poultry industry throughout the world. seven broiler grandparent flocks of iran (six broiler strains) were sampled randomly at the ages of 8-63 wk (100 samples from each flock) for antibody detection to alv-j, mg, and ms by...
