Molecular Epidemiology of Fowl Aviadenoviruses in Broiler Chickens from Vaccinated and Nonvaccinated Breeders.

Fowl aviadenoviruses (FAdVs) are widely distributed among poultry populations, leading to various diseases, immunosuppression, and economic losses. Molecular characterization and phylogenetic analysis of circulating FAdV isolates play a critical role in epidemiologic studies, contributing to the control, monitoring, and prevention of related outbreaks. This study aimed to determine the serotypes of FAdV and reveal the molecular epidemiology in broiler chicken flocks.

Antibiotic Resistance Profile of Rarely Isolated Salmonella Serotypes from Poultry in Turkey.

This study investigated five strains of each serotype of Salmonella Agona, Salmonella Heidelberg, Salmonella Hindmarsh, Salmonella Kouka, Salmonella Muenchen, Salmonella Ottmarchen, Salmonella Saintpaul and Salmonella II, isolated during the 2014-2017 period. Disc diffusion was used to identify the phenotypic profiles of antibiotic resistance to 12 antimicrobials while the presence of antibiotic resistance genes (ARGs) was detected by PCR. The most sensitive serotype was S.

Distribution of antimicrobial resistance and virulence markers in chicken originated Proteus mirabilis isolates.

Proteus mirabilis is a common enteric bacterium in livestock and humans. The increase and spread of the antimicrobial resistant P. mirabilis is considered alarming worldwide.

The effects of using UV light instead of formaldehyde in disinfection of hatching eggs on shell microbial load, embryo development, hatchability, and chick characteristics.

In this study, it was aimed to determine the effects of using UV light instead of formaldehyde in disinfection of hatching eggs on the microbial load, shell and yolk compositions, embryo development, hatching results and chick characteristics. 552 hatching eggs were divided into formaldehyde fumigation and disinfection with UV groups. After disinfection, bacteriological growth was not observed in groups.

Genotyping and antimicrobial resistance profiles of chicken originated Salmonella Enteritidis isolates.

Salmonellosis is a common foodborne zoonosis worldwide. The most common Salmonella serovar in humans is Salmonella enterica subsp. enterica serovar Enteritidis (50.
