Background: Much attention has been paid to poultry feed processing and the contamination In Iran in order to improve the production and reduce the waste.  No information is available on the fungal contamination and the strains found in processed (pellet) and non-processed (mash) poultry feeds. This study was designed to determine the hygienic condition and the risk of fungal contamination...

Colibacillosis results from infection with avian pathogenic Escherichia coli bacteria. Healthy broilers are resistant to inhaled E. coli, but previous infection with vaccine or virulent strains of Infectious Bronchitis Virus (IBV) predisposes birds for severe colibacillosis. We investigated whether IBV affects recruitment and function of phagocytic cells and examined NO production, phagocytic a...

BACKGROUND The frequency of avian influenza A virus infections among poultry workers is not well understood. METHODS A seroprevalence study of market poultry workers and persons without occupational poultry exposure was conducted during 2001 in Hanoi, Vietnam. Sera were tested for avian influenza H5 and H9 antibodies by microneutralization and Western blot assays. RESULTS Seroprevalence of ...

Infections with avian pathogenic Escherichia coli (APEC) cause colibacillosis, an acute and largely systemic disease resulting in significant economic losses in poultry industry worldwide. Although various virulence-associated genes have been identified in APEC, their actual role in pathogenesis is still not fully understood, and, furthermore, certain steps of the infection process have not bee...

Avian pathogenic Escherichia coli is an important etiological agent of avian colibacillosis, which manifests as respiratory, hematogenous, meningitic, and enteric infections in poultry. It is also a potential zoonotic threat to human health. The diverse genomes of APEC strains largely hinder disease prevention and control measures. In the current study, pyrosequencing was used to analyze and ch...

Colibacillosis is known as a fatal bacterial disease resulting in a high level of commercial loss worldwide. This study amid to elucidate the sequence, genetic characteristics, and phylogeny of the bor gene in Escherichia coli (E. coli) strain c1378 (O78:K80) isolated from avian colibacillosis in Iran and develop a rapid and optimal polymerase chain reaction (PCR) mol...

Colibacillosis, caused by avian pathogenic Escherichia coli (APEC) is a major problem for the poultry industry resulting in significant losses annually. Previous work in our lab and by others has shown that the increased serum survival gene (iss) is a common trait associated with the virulence of APEC. This gene was first described for its contributions to E. coli serum resistance. However, rec...

Systemic infections by avian pathogenic Escherichia coli (APEC) are economically devastating to poultry industries worldwide. E. coli strains belonging to serotypes O1, O2, O18 and O78 are preferentially associated with avian colibacillosis. The rfb gene cluster controlling O antigen synthesis is usually various among different E. coli serotypes. In present study, the rfb gene clusters of E. co...
