Comparison of Different Sample Types for Salmonella Detection From Chicken Layer Breeder Flocks

Staphylococcus aureus in commercial breeder layer flocks

Four flocks of Layer breeders, consist of 28000 (7000 birds each) at 25 weeks of age, hatchery and one day old chicks were subjected to swab sampling in order to isolate Staphylococcus aureus during the period from May till June 2008. Results revealed that more than half of the overall swab samples were positive (52.04%). Different isolation rates were recorded between four flocks, ranging from...

Genetic diversity of Gallibacterium anatis isolates from different chicken flocks.

Amplified fragment length polymorphisms (AFLPs) were used to characterize the genotypic diversity of a total of 114 Gallibacterium anatis isolates originating from a reference collection representing 15 biovars from four countries and isolates obtained from tracheal and cloacal swab samples of chickens from an organic, egg-producing flock and a layer parent flock. A subset of strains was also c...

Detection and Molecular Characterization of Chicken Astrovirus from Broiler Flocks in Iran: The First Report

Background and Aims: Enteric diseases have had detrimental impacts on commercial poultry through depressing growth rates and caused considerable economic losses to poultry producers. Chicken astrovirus (CAstV) is one of the most common viruses related to enteric diseases in chickens, especially in young chicks. Materials and Methods: Chicken astroviruses were detected by reverse transcriptase ...

Detection of avian leukosis virus (ALV) in albumen of Shiraz commercial and local layer flocks using ELISA and RT-PCR

Avian leukosis viruses (ALVS) cause different types of tumours in poultry and can affect the health and egg production of the birds. To investigate the presence of the virus in chicken layer flocks in Shiraz, 222 egg albumen from local layer breeder (25 eggs), local layer grand parent (30 eggs), broiler breeder (60 eggs), commercial layer (46 eggs) and broiler grand parent (61 eggs) were tested...

Cultivation of samples of hatcher chick fluff, floor litter and feces for the detection of Salmonella infection in chicken flocks.
