A high prevalence of tylosin resistance among Staphylococcus aureus strains isolated from bovine mastitis
The macrolides appear to have considerable effects for treatment of bovine mastitis because of excellent diffusion into the mammary gland, long half-life, low protein binding, high intracellular concentration and lipid solubility. Acquired resistance to macrolides in Staphylococcus aureus is primarily related to target-site modification through acquisition of an erm gene. In t...
متن کاملComparison of microRNA Profiles between Bovine Mammary Glands Infected with Staphylococcus aureus and Escherichia coli
MicroRNAs (miRNAs) play crucial roles in regulating innate and adaptive immunity in humans and animals. Infection with E. coli or S. aureus can cause inflammation of the mammary glands, which results in significant economic losses in dairy cattle. However, the regulatory mechanisms of miRNAs in response to E. coli or S. aureus infection in bovine mammary glands have not been thoroughly explored...
متن کاملTranscriptome MicroRNA Profiling of Bovine Mammary Glands Infected with Staphylococcus aureus
MicroRNAs are small non-coding RNA molecules that are important regulators of gene expression at the post-transcriptional level. miRNAs impact the processes of cell proliferation, differentiation and apoptosis. Thus, the regulation of miRNA expression profiles associated with mastitis will be conducive for its control. In this study, Staphylococcus aureus (S. aureus) was administered to the mam...
متن کاملRegeneration of mammary glands in vivo from isolated mammary ducts.
Rat mammary ducts, free of buds, can alone regenerate complete mammary trees when transplanted into the interscapular fat pads of syngeneic host rats. All the main mammary cell types are identified within such outgrowths. Epithelial cells, which show the presence of milk fat globule membrane antigens and microvilli on their luminal surfaces, line the ducts. Basal cells surrounding the ducts sho...
متن کاملAntibiotic Susceptibility and Plasmid Profiles of Staphylococcus aureus Strains Isolated from Bovine Subclinical Mastitis in Tabriz, Iran
ABSTRACT Background and Objectives: Mastitis caused by Staphylococcus aureus is a widely distributed disease in cattle, goats and sheep. The infection is often subclinical in cattle, leading to reduced milk production and quality, but acute catarrhal or even gangrenous inflammation may also occur. The aim of this study was to investigate resistance of S. au...
