Characterization of a sucrase gene from Staphylococcus xylosus.
The Staphylococcus xylosus gene scrB, encoding a sucrase, has been isolated from a genomic library of S. xylosus constructed in Escherichia coli. The gene was detected by its ability to confer utilization of the glucose and fructose residues of raffinose in an E. coli strain that is not able to metabolize galactose. It was found to reside within a 1.8-kb DNA fragment, the nucleotide sequence of...
متن کاملCharacterization of Salmonella spp. isolated from an integrated broiler chicken operation in Korea.
The purpose of this study was to investigate the biological and genetic characterization of persistent Salmonella isolates in an integrated broiler chicken operation, in an attempt to elucidate the source of contamination. From the breeder farm, the hatchery, the broiler farm and the chicken slaughter house of an integrated broiler chicken operation, a total of 6 serotypes were observed. Althou...
متن کاملCharacterization of the single superoxide dismutase of Staphylococcus xylosus.
Staphylococcus xylosus is a facultative anaerobic bacterium used as a starter culture for fermented meat products. In an attempt to analyze the antioxidant capacities of this organism, the superoxide dismutase (SOD) was characterized. S. xylosus contains a single cytoplasmic SOD, which was not inhibited by H2O2. The SOD activity in crude extracts was completely lost upon metal depletion, but it...
متن کاملDetection 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 ...
متن کاملGenotyping of Infectious bronchitis viruses isolated from broiler chicken farms in Iran during 2015-2016
BACKGROUND: Avian infectious bronchitis is considered as an important viral disease worldwide. Genotyping based on the S1 subunit of spike protein gene of the causative agent, avian infectious bronchitis virus, can be used to classify IBV isolates. Objective: This survey was carried out to characterize the infectious bronchitis virus (IBV) genotypes circulating in Iran and determine their preva...
