Abstract Hesperidin (HE), chrysin (CH) and naringenin (NA) are flavonoids, being the most important group of polyphenols, show anti-inflammatory properties which have been demonstrated on various models. Polyphenols a lot biological properties, such as antioxidative, antiviral, immunomodulatory anticancer activities. However, effect mastitis has not yet described. This research aimed to analyse...

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...

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...

Anaerobic digestion is one of the major biological waste treatment processes in use today. Waste milk from mastitic cows treated with cefazolin is considered a good candidate as a co-substrate in anaerobic digestion. The objective of this study was to determine the effect of cefazolin (10 mg L) and waste milk on reduction of multi-drug resistant bacteria (MDRB) resistant to three groups of anti...
