AIM The aim was to evaluate the in vitro activity of fosfomycin against common uropathogens in a fosfomycin-naive population in India. METHODS The authors prospectively collected and tested all consecutive isolates of Escherichia coli and Enterococcus spp. from urine samples between December 2009 and April 2010. RESULTS A total of 3141 isolates were(More)
Call this idea, according to which a cause is a "differencemaker," the difference-making idea. The difference-making idea famously motivated Lewis's counterfactual theory, an attempt to analyze the concept of cause in terms of the relation of counterfactual dependence between events.2 However, as we will see, Lewis's counterfactual theory ends up(More)
BACKGROUND Streptococcus pneumoniae causes life-threatening infections such as meningitis, pneumonia, and febrile bacteremia, particularly in young children. The increasing number of drug-resistant isolates has highlighted the necessity for intervening and controlling disease. To achieve this, information is needed on serotype distribution and patterns of(More)
The widespread use of antimicrobials has increased the occurrence of multidrug resistant microbes. The commonest mechanism of antimicrobial resistance in Enterobacteriaceae is production of β-lactamases such as metallo-β-lactamases (MBL) and extended spectrum β-lactamases (ESBL). Few studies have used a molecular approach to characterize the prevalence of(More)
BACKGROUND Streptococcus pneumoniae infection is a serious problem worldwide and the case fatality rate remains high. The aim of this study was to analyze the distribution of pneumococcal serotypes causing invasive pneumococcal disease (IPD), to survey the potential coverage of present and future vaccines, and to investigate differences between serotypes(More)
Streptococcus pneumoniae causes life threatening infections and necessitate for impediment and controlling disease; to conquer this, information is needed about serotype distribution and patterns of antibiotic resistance. The present study was to determine the serotype distribution of S. pneumoniae isolated from the entire age group individual and to(More)
Venlafaxine (VEN), a well accepted anti-depressant, is metabolized through the cytochrome P 450 (CYP) 2D6 isozyme to form O-desmethyvenlafaxine (ODV). Due to the involvement of CYP2D6, the formation of ODV is influenced by genetic polymorphism. We used standard tools of assessment to explore the phenotypic distribution in a retrospective manner using the(More)
M ultidrug resistance (MDR) of Acinetobacter baumannii increasingly jeopardizes the health care setting leading to substantial mortality and morbidity globally. During the past decade, entirely resistant A. baumannii strains presented a real challenge to clinicians and posed difficulties in therapy (1, 2). MDR of A. baumannii associated infections, with(More)
BACKGROUND Co production of 16S rRNA methylases gene and β-Lactamase gene among Enterobacteriaceae isolates conferring resistance to both therapeutic options has serious implications for clinicians worldwide. METHODS To study co existence of 16S rRNA methylases (armA, rmtA, rmtB, rmtC, rmtD, and npmA) and β-Lactamase (blaTEM-1, blaSHV-12, blaCTX-M-14)(More)
