Molecular characterization of avian adenoviruses in Iranian broiler flocks
This study was conducted to molecularly detect avian adenoviruses in broiler flocks showing liver lesions and respiratory syndrome in northeast Iran. In total, 60 tissue samples were collected from broiler farms with liver lesions, respiratory syndrome and also from clinically healthy flocks. Six samples were positive; however, three samples were selected for molecular studies. PCR products wer...
متن کاملSerological Survey of Infectious Laryngotracheitis in Broiler Flocks, Iran, 2018
Infectious Laryngotrachitis (ILT) is an acute respiratory disease with high morbidity and low mortality in poultry. ILT is caused by Gallid herpesvirus 1 (GaHV-1), a member of the Iltovirus genus and family Herpesviridae. It resulted in notable economic losses due to decreasing the growth rates, egg production, and increasing the mortality in commercial poultry, especially layer flocks, and usu...
متن کاملFlies and Campylobacter Infection of Broiler Flocks
A total of 8.2% of flies caught outside a broiler house in Denmark had the potential to transmit Campylobacter jejuni to chickens, and hundreds of flies per day passed through the ventilation system into the broiler house. Our study suggests that flies may be an important source of Campylobacter infection of broiler flocks in summer.
متن کاملRisk Factors and Likelihood of Campylobacter Colonization in Broiler Flocks
Campylobacter was investigated in cecal droppings, feces, and cloacal swabs of 22 flocks of 3 to 5 week-old broilers. Risk factors and the likelihood of the presence of this agent in these flocks were determined. Management practices, such as cleaning and disinfection, feeding, drinkers, and litter treatments, were assessed. Results were evaluated using Odds Ratio (OR) test, and their significa...
متن کاملModelling transmission dynamics of Campylobacter in Dutch broiler flocks
Within the multi-disciplinary CARMA (Campylobacter Risk Management and Assessment) project it was decided to focus on evaluation of interventions in the chicken meat chain. To assess the effect of control measures on the farm we developed a model on Campylobacter transmission in Dutch broilers and broiler flocks, resulting in an estimate of the Campylobacter prevalence in broilers for slaughter...
