Background and Objectives: Staphylococcus aureus is an important cause of nosocomial and community-acquired infections in every region of the world. Clindamycin is one of the alternative agents used to treat S. aureus infections and accurate identification of clindamycin resistance is important to prevent therapeutic failure. Unfortunately, inducible clindamycin resistance is ...
We developed multiplex polymerase chain reaction (PCR) to detect aac(6 ')/aph(2 "), aph(3 ')-IIIa, and ant(4 ')-Ia, the genes encoding the most clinically relevant amino-glycoside modifying enzymes (AME), and simultaneously, the methicillin resistant gene, mecA, in Staphylococcus species. Clinical isolates of 45 S. aureus and 47 coagulase negative staphylococci (CNS) from tertiary university ho...
The influence of culture medium, incubation temperature, and antibiotic content on the reliability of methicillin disc-sensitivity tests on strains of Staphylococcus aureus was evaluated. Tests were performed with an inoculum giving semiconfluent growth of colonies on four media, with 5-mug and 10-mug methicillin discs at incubation temperatures of 30, 35, and 37 degrees C. With Sensitest agar ...
Background & Aims : Staphylococcus aureus is a gram-positivecoccal bacteriumthat that can cause a range of infections. Methicillin resistance in these bacteria is often in companion with resistance to multiple antibiotics. High prevalence of these isolates can cause treatment failure. Phosphomycin is a peptidoglycan biosynthesis inhibitor that is used in treating infections caused by multi-...
BACKGROUND In this study, we determined the susceptibility patterns of Staphylococcus aureus strains to various antimicrobials and prevalence of inducible clindamycin resistance (ICR) in these isolates. METHODS Two hundred and one S aureus strains, isolated from various clinical samples, were included in the study. Antibiotic susceptibilities were studied by disc diffusion method on the basis...
OBJECTIVES To analyse the possible relationship between consumption of old and new MRSA-active antibiotics and burden of MRSA in acute care hospitals in Catalonia during the period 2007-12. METHODS Fifty-four hospitals participating in the VINCat Programme were included. Proportion of MRSA (resistant isolates of Staphylococcus aureus per 100 isolates of S. aureus tested), incidence of new cas...
appear to have subsequently acquired methicillin resistance through horizontal transfer of SCCmec type IV. The spa type of the Italian isolate comprises 7 nucleotide repeats, indicated by XJ4AKAOM in the alphabetical code. This repeat sequence differs from that of the classical SWP clone, indicated by XKAKAOMQ (8), by only 1 bp in the second repeat and loss of the last Q repeat. In spite of the...
INTRODUCTION Clindamycin is an alternative antibiotic in the treatment of Staphylococcus aureus (S.aureus) infections, both in infections by methicillin susceptible and resistant (MSSA and MRSA) strains. The major problem of use of clindamycin for staphylococcal infections is the presence of inducible clindamycin resistance that can lead to treatment failure in such infections. AIM To determi...
The incidences of inducible clindamycin resistance at two hospitals (an inner-city hospital and a suburban community hospital) were 7 and 12% for methicillin-resistant Staphylococcus aureus, 20 and 19% for methicillin-susceptible S. aureus, and 14 and 35% for coagulase-negative staphylococci, respectively. Given the variability of inducible resistance to clindamycin found in our two hospitals, ...
