Avian pathogenic E. coli and human extraintestinal pathogenic E. coli serotypes O1, O2 and O18 strains isolated from different hosts are generally located in phylogroup B2 and ST complex 95, and they share similar genetic characteristics and pathogenicity, with no or minimal host specificity. They are popular objects for the study of ExPEC genetic(More)
BACKGROUND Swine extraintestinal pathogenic Escherichia coli (ExPEC) is an important pathogen that leads to economic and welfare costs in the swine industry worldwide, and is occurring with increasing frequency in China. By far, various virulence factors have been recognized in ExPEC. Here, we investigated the virulence genotypes and clonal structure of(More)
Staphylococcus aureus is a primary pathogen that causes bovine mastitis resulting in serious economic losses and herd management problems in dairy cows. A novel bacteriophage, JS01, specifically infecting bovine S. aureus, was isolated from milk of mastitis-affected cattle. TEM observation showed that it belonged to the family Siphovirus. The JS01 strain(More)
