Fluoroquinolone resistance in Streptococcus pyogenes.
Streptococcus pyogenes isolated from blood and urine samples obtained from a 78-year-old woman was tested for susceptibility, and fluoroquinolone resistance (minimum inhibitory concentration of levofloxacin, 16 microg/mL) was found. DNA amplification and sequencing revealed a serine81-->tyrosine substitution in gyrA and 2 substitutions in parC: serine79-->phenylalanine and alanine121-->valine. ...
متن کاملChloramphenicol Resistance in Micrococcus Pyogenes
In an earlier report from this laboratory (Wilson and Ramsey, 1955) an antagonism between chloramphenicol and complex materials (yeast extract, proteose peptone #3) was noted. It was suggested that the antagonism observed was possibly due to stimulation of growth, rather than to direct antagonism of the antibiotic. In order to examine more critically the respective roles of stimulation and dire...

عفونت و تهاجم ارگانیسم های انگلی به بدن، عامل اصلی بیماری و مرگ انسانها از آغاز بشریت بوده است . در حقیقت بسیاری از اشکال حیات بدون غلبه بر ارگانیسم های زنده دیگر، قادر به ادامه زندگی نخواهند بود. انسانها معمولا مستعد تهاجم ارگانیسم های کوچکتری مانند کرمها، آمیب ها، قارچها، باکتریها و ویروسها هستند. این عوامل مکان خاصی را در بدن انتخاب کرده، مواد ضروری لازم برای حیات و تکثیر خود را دریافت نموده...
متن کاملErythromycin resistance in Streptococcus pyogenes in Italy.
In a prospective study of acute pharyngitis in Italian children, 69 (38.3%) of 180 isolates of Streptococcus pyogenes were resistant to macrolides. S. pyogenes was eradicated in 12 (63.1%) of 19 patients with erythromycin-resistant S. pyogenes treated with clarithromycin and in 22 (88%) of 25 patients with erythromycin-susceptible strains. The constitutive-resistant phenotype was correlated wit...
متن کاملStreptococcus pyogenes erythromycin resistance in Italy.
Letters importance of this symptomatic shedding in transmission among preschool children is well established (3); however, that of symptom-free shedding in adults is unknown. We report here that the rate of symptom-free STEC O157:H7 shedding is higher in adults 30 to 49 years of age than in others. STEC infections have been notifiable in Japan since August 1996. When STEC is found in the feces ...
