Prevalence of virulence and resistance to antibiotics in pathogenic enterococci isolated from mastitic cows
The prevalence of enterococci was examined in 280 milk samples collected from dairy cattle diagnosed with mastitis in three provinces of western China. Sixty strains of enterococci were isolated, and the species were determined based on their biochemical characters and 16S rRNA sequences. Resistance to seven antibiotic agents, frequency of seven virulence genes and pathogenicity in Kunming mice...
متن کاملAntimicrobial Resistance in Enterococci
Enterococci show intrinsic low resistance to a large number of antibiotics (β-lactams, lincosamines, aminoglycosides and trimetoprim-sulfametoxazol). In addition, Enterococci can acquire new resistance to antimicrobial agents. This can happen by mutation or acquisition of extrachromosomal DNA, as plasmids or transposons. Resistance to erythromycin, aminoglycosides and tetracycline are common. R...
متن کاملMastitis Pathogens Isolated from Samples of Milk in Dairy Cows and Their Resistance against Antimicrobial Agents
The objective of this study was to evaluate the effectiveness of different antibiotics against mastitis causing microorganisms during first phase of lactation in herd of 320 Holstein cows in east of Slovakia. Milk samples from quarters were cultured and identified bacteria were subjected to antimicrobial susceptibility test by disc diffusion method to a large number of antibiotics. The results ...
متن کاملResistance of Yeasts and Algae Isolated from Cow Mastitic Milk to Antimicrobial Agents
The objective of this study was to determine the antimicrobial resistance of 319 yeast strains and 168 algae strains isolated from cows` mastitic milk. The in vitro susceptibility to 10 antifungals and 10 antibiotics was examined by disc diffusion method. Above 75% of yeast strains were resistant to amphotericin B, 66% to fluconazole, and 40% to pimaricin and itrakonazole. Algae strains were re...
متن کاملA comparison of milk protein status of healthy and mastitic cows under denaturing conditions
Mastitis is one of the most important diseases of dairy cattle in the world. The identification and characterization of the constituent proteins in milk can be useful for studying the biochemistry and pathogenesis of mastitis. In this study, the electrophoretic patterns of milk from 10 healthy and 30 mastitic cows were studied. All of the latter milk samples were California Mastitis Test (CMT) ...
