Heat stress and exhaustion is one of the top causes of chicken death. For those new to backyard chicken farming, it is important you learn to recognize the signs of this serious condition and how to keep your chickens cool and hydrated. Chicks, especially, need extra attention to help them remain healthy. For a flock of laying hens, knowing how to prevent heat exhaustion and treat a chicken suf...

Avian pathogenic Escherichia coli (APEC) strains cause systemic and localized infections in poultry, jointly termed colibacillosis. Avian colibacillosis is responsible for significant economic losses to the poultry industry due to disease treatment, decrease in growth rate and egg production, and mortality. APEC are also considered a potential zoonotic risk for humans. Fully elucidating the vir...

Colibacillosis accounts for annual multimillion dollar losses in the poultry industry, and control of this disease is hampered by limited understanding of the virulence mechanisms used by avian pathogenic Escherichia coli (APEC). Previous work in our laboratory has found that the presence of the increased serum survival gene (iss) is strongly associated with APEC but not commensal E. coli, maki...

Understanding the distributions of poultry diseases will help planning for disease control and prevention more effectively. Studies on poultry diseases in Iran are scarce. We investigated the incidence of mortality in broiler chicken flocks in Iran as part of a national project. Specifically, documents from September 2004 to November 2005 related to the mortality of broilers that were covered b...

Salmonellosis and colibacillosis in poultry are two major zoonotic bacterial diseases often transmitted through eggs to the offspring. To detect prevalence of Salmonella and Escherichia coli bacteria in table purpose poultry eggs 85 eggs were sampled from Bareilly and Dehradun retail markets and an organized farm in Izatnagar. Salmonella could be isolated from four eggs and E. coli from 24 eggs...

The goal of this study was to isolate and characterize a more complete set of phages that are active against Escherichia coli serogroups O1, O2, and O78, the main causative agents of avian colibacillosis. A mixture of E. coli (O1:K1), (O2:K1), and (O78:K80) was used as a host to isolate phages from wastewater and fecal samples from poultry processing plants. Seven phages were isolated; only 2 o...

In this study, 90 internal organ samples of poultry with symptoms of colibacillosis were obtained from Maragheh poultry farms in East Azerbaijan, Iran. In total, 70 bacterial isolates were confirmed as Escherichia coli (E. coli) strains using standard biochemical tests, and antibiotic sensitivity was determined by the disk diffusion method. Antibiotics used in this study included ampicillin, pe...

Colibacillosis is a disease caused by Escherichia coli and remains major concern in poultry production, as it leads to significant economic losses due carcass condemnation clinical symptoms. The development of antimicrobial resistance growing problem worldwide concern. Lysogenic bacteriophages are effective vectors for acquiring disseminating antibiotic genes (ARGs). aim this study was investig...
