Background: The emergence and propagation of different phylogenetic groups of antimicrobial-resistant E. coli have become a worldwide health concern in human and veterinary medicine. Therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant E. coli is important for therapeutic and economic purposes. The aims of this study were to determine phylogenetic groups and patter...
We successfully cultivated the rickettsia Cowdria ruminantium, in bovine endothelial cell lines (Bovine Umbilical Endothelial Cells/BUEC and Bovine microvasculature Cells/BMC) and also in primary endothelial cells of bovine origin (Bovine Aorta Endothelial cells/BAEC) and more surprisingly in cells of human origin--Human Umbilical Vein Endothelial Cells/HUVEC--and Human Endothelial Cells from t...
staphylococci isolated from 98 mastitic cow’s milk samples were analyzed for the production of alpha,beta and delta-hemolysin on sheep, bovine and horse red blood cells and in vitro susceptibility to several antimicrobial agents. out of a total of 18 isolated strains, 100% demonstrated hemolytic activity either alone or in combined forms. among 8 isolates of s. aureus 3 isolates produced α/β an...
Characterization of transmission routes of Salmonella among various food-animal reservoirs and their antibiogram is crucial for appropriate intervention and medical treatment. Here, we analyzed 3728 Salmonella enterica serovar Newport (S. Newport) isolates collected from various food-animals, retail meats and humans in the United States between 1996 and 2015, based on their minimum inhibitory c...
Milk is considered a nutritious food because it contains several important nutrients including proteins and vitamins. Conversely, it can be a vehicle for several pathogenic bacteria such as Staphylococcus aureus. This study aimed to analyze the frequency of genes encoding the nine Staphylococcal enterotoxins (SEs) and enterotoxin gene profiles in S. aureus isolates derived from raw bovine milk....
abstract translation has become a cultural act which plays a significant role in human life. with the emergence of functional translation theories, and skopos theory in particular, translation has been considered as a purposeful, interpersonal and intercultural activity which is produced for particular recipients and directed by a specific purpose. this purpose determines the translatio...
cryptosporidium is an apicomplexan parasite of humans and a wild range of domestic as well as wild animals. an 833-bp fragment of the 18s-rrna gene was used to identify cryptosporidium spp. recovered from children and adult patients, in human immunodeficiency virus (hiv) positive and negative patients in iran. initial identification of cryptosporidiosis was carried out by ziehl-neelsen acid-fas...
Staphylococcus aureus is a main cause of bovine mastitis and a major pathogen affecting human health. The emergence and spread of methicillin-resistant Staphylococcus aureus (MRSA) has become a significant concern for both animal health and public health. This study investigated the incidence of MRSA in milk samples collected from dairy cows with clinical mastitis and characterized the MRSA iso...
background and objectives: shiga toxin-producing escherichia coli (stec) have emerged as human pathogens and con- tamination via animal origin has been a major public health concern. we compared the distribution of phylogenetic groups and prevalence of stx gene variants among the pathogenic strains of escherichia coli isolated from feces of diarrheatic calves in tehran suburb farms. materials a...
Staphylococcus aureus is an important cause of bovine mastitis worldwide, and effective preventive or therapeutic modalities are lacking. Although most human S. aureus isolates produce capsular polysaccharides (CPs), few reports have described the prevalence of capsules on bovine isolates. This information is important for the rational design of a vaccine for the prevention of staphylococcal ma...
