Heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) clinical strain Mu3 spontaneously generates VISA strains at an extremely high frequency (≥1×10(-6)). The generated VISA strains usually grow more slowly than does the parent hVISA strain, but they form colonies on vancomycin-containing agar plates before 48 h of incubation. However, we noticed a curious group of VISA strains, d...
Background and Objective: Vancomycin is frequently the antibiotic of choice for the treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA). For the last years, the incidence of vancomycin-intermediate S. aureus (VISA) and vancomycin-resistant S. aureus (VRSA) has been increased in various parts of the world. The present study ...
We evaluated several 3-day antimicrobial regimens in the treatment of experimental endocarditis caused by an oxacillin-resistant Staphylococcus aureus strain exhibiting intermediate susceptibility in vitro to vancomycin (VISA). Neither vancomycin alone nor trovafloxacin exhibited in vivo efficacy; addition of amikacin to vancomycin yielded a modest in vivo effect. In contrast, the combination o...
Vancomycin-intermediate Staphylococcus aureus (VISA) are an emerging problem. We observed a statistically significant inverse relationship in the MICs of vancomycin and oxacillin in S. aureus isolates from a patient undergoing hemodialysis who received 26 weeks of treatment with vancomycin during November 1999 through April 2000. All isolates were mecA positive and were indistinguishable by pul...
زمینه و اهداف: استافیلوکوکوس اورئوس یکی از عوامل مهم عفونت های بیمارستانی می باشد. اخیرا افزایش مقاومت های دارویی مختلف آن بر مشکلات درمانی افزوده است. بروز سویه هایVRSA( Vancomycin resistant staphylococcus aureus) ، نگرانی های زیادی را در زمینه درمان ایجاد نموده است. هدف از این مطالعه بررسی شیوع استافیلوکوکوس اورئوس با کاهش حساسیت نسبت به ونکومایسین در نمونه های بیماران مراجعه کننده به بیمارست...
Skill Based Immigrant Selection and Labor Market Outcomes by Visa Category Attracting skilled immigrants is emerging as an important policy goal for immigrant receiving countries. This article first discusses the economic rationale for immigrant selection. Selection mechanisms of receiving countries are reviewed in the context of deteriorating labor market outcomes for immigrants across destina...
