Pulsed-field gel electrophoresis (PFGE) was performed on 122 neonatal bloodstream isolates of group B streptococci (GBS) to further examine the relationship between macrolide resistance and serotype V GBS (GBS-V). Over one-third (35%) of macrolide-resistant GBS belonged to a single PFGE subtype of GBS-V, which was also the most common GBS-V subtype noted in previous Centers for Disease Control ...
During 2011, 160 nasal samples were taken from pigs on 8 different farms in Lithuania. Four methicillin-resistant Staphylococcus aureus (MRSA) isolates were obtained. The isolates were ST398, spa type t011 and SCCmec V and none carried the lukF/lukS genes. Strains were resistant to tetracycline, attributed to tetK and tetM genes, and to erythromycin owing to the ermB gene. One MRSA strain was r...
هدف: استفاده طولانیمدت از ماکرولید، لینکوزامید و استرپتوگرامین B (MLSB) برای درمان عفونتهای ایجاد شده توسط استافیلوکوکوس اورئوس تولیدکننده توکسین1 سندروم شوک توکسیک(TSST-1) میتواند زمینه ظهور سویههای مقاوم را فراهم کند. هدف از این مطالعه، تعیین الگوی مقاومت آنتیبیوتیکی به ماکرولیدها و تتراسایکلینها و ژنهای دخیل در بروز این مقاومتها در سویههای استافیلوکوکوس اورئوس تولیدTSST-1 میباشد....
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...
مقدمه: استافیلوکوکوس اورئوس به واسطه کلونیزاسیون مناسب در انسان، آلوده کننده محیط های بیمارستانی است. این باکتری دارای تنوع ژنتیکی جهت به دست آوردن مقاومت به عوامل ضد میکروبی متعدد می باشد. مطالعه حاضر به منظور تعیین میزان شیوع و اساس ژنتیکی مقاومت به اریترومایسین و کلیندامایسین در استافیلوکوکوس های جدا شده از بیمارانی در شهر سنندج انجام شده است مواد و روش ها: صد و پنجاه سویه بالینی استافیلوک...
BACKGROUND Group B Streptococcus (GBS) remains a major cause of neonatal sepsis and is also associated with invasive and noninvasive infections in pregnant women and non-pregnant adults, elderly and patients with underlying medical conditions. Ten capsular serotypes have been recognized, and determination of their distribution within a specific population or geographical region is important as ...
Urban waterways represent a natural reservoir of antibiotic resistance which may provide a source of transferable genetic elements to human commensal bacteria and pathogens. The objective of this study was to evaluate antibiotic resistance of Escherichia coli isolated from the urban waterways of Milwaukee, WI compared to those from Milwaukee sewage and a clinical setting in Milwaukee. Antibioti...
The antibiotic resistances of 45 lactic acid bacteria strains belonging to the genera Lactobacillus, Streptococcus, Lactococcus, Pediococcus, and Leuconostoc were investigated. The objective was to determine antibiotic resistances and to verify these at the genetic level, as is currently suggested by the European "qualified presumption of safety" safety evaluation system for industrial starter ...
To better understand the emergence and transmission of antibiotic-resistant Streptococcus agalactiae, we compared phenotypic and genotypic characteristics of 52 human and 83 bovine S. agalactiae isolates. Serotypes found among isolates from human hosts included V (48.1%), III (19.2%), Ia and Ib (13.5% each), and II (5.8%). Among isolates from bovine hosts, molecular serotypes III and II were pr...
One hundred and seven clinical isolates of Streptococcus pyogenes, 80 susceptible to macrolides and 27 resistant to erythromycin A (MIC >0.5 microgram/ml), were examined. The erythromycin A-lincomycin double-disk test assigned 7 resistant strains to the M-phenotype, 8 to the inducible macrolide, lincosamide, and streptogramin B resistance (iMLS(B)) phenotype, and 12 to the constitutive MLS(B) r...
