staphylococcus aureus is generally regarded as a leading cause of mastitis in dairy cattle. the aim of this study was to investigate the pattern of agr groups and any possible relationship between agr groups and antibiotic resistance among s. aureus strains isolated from bovine mastitis in northeast of iran. for this purpose, a total of 300 bovine mastitic milk samples were taken from dairy ind...
Recent reports raised concerns about the role that farm stock may play in the dissemination of extended-spectrum β-lactamase (ESBL)-producing bacteria. This study characterized the ESBLs in two Escherichia coli and three Klebsiella pneumoniae subsp. pneumoniae isolates from cases of clinical bovine mastitis in the United Kingdom. Bacterial culture and sensitivity testing of bovine mastitic milk...
Associations between known or putative virulence factors of Shiga toxin-producing Escherichia coli and disease in humans were investigated. Univariate analysis and multivariate logistic regression analysis of a set of 237 isolates from 118 serotypes showed significant associations between the presence of genes for intimin (eae) and Shiga toxin 2 (stx2) and isolates from serotypes reported in hu...
During a limited epidemiological study, the serotype specificities of several isolates of bovine rotavirus, exhibiting identical electropherotypes, from a single cattle farm near Bangalore, India, could not be determined using a panel of serotyping monoclonal antibodies (MAbs) specific for G serotypes 1-6 and 10. To determine the genotypes of these isolates, the nucleotide sequences of the gene...
Streptococcus agalactiae is a major contagious pathogen causing bovine sub-clinical mastitis. The present investigation was carried out to determine some phenotypic characteristics of the S. agalactiae strains isolated from bovine mastitis cases in dairy cows of Shahrekord in the west-center of Iran. One hundred eighty California mastitis test (CMT) positive milk samples were ...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
ii abstract the legend of human being’s refulgence was distorted completely in the age of modernity. this new age, had some drastic negative effects, besides its positive qualities. one significant negative effect of it was the emergence of neurosis in human beings. aldous huxley’s brave new world was one of the novels of the 02 th century that contained the prophecy of criticizing ...
Background and aim: Regarding to the importance of Staphylococcus aureuscolonization in bovine mastitis and the role of biofilm in its pathogenesis, the aim of the present study were to assessment of biofilm production and identification of biofilm related genes among S. aureus isolated from bovine with subclinical mastitis. Materials and Methods: In this cross-sectional study, a total of 502 m...
A total of 90 Escherichia coli O157 isolates recovered from humans, ca�le, and pigs, were examined for the presence of the H7 antigen, ability to produce Shiga toxins and enterohemolysin as well as for antimicrobial resistance and biochemical properties. Fourteen of the human strains (n = 23) and 21 of the bovine isolates (n = 29) were of the O157:H7 serotype as determined by agglutination and ...
