Zygomycosis is an emerging infection worldwide. A study was conducted to understand its spectrum in the Indian scenario. All patients diagnosed for invasive zygomycosis at a tertiary care center in north India from 2000-2004, were retrospectively analyzed. A total of 178 cases (mean average of 35.6 cases/year) of zygomycosis were diagnosed.(More)
BACKGROUND As fungal endophthalmitis is an emerging challenge, the study was carried out to determine the prevalence and the spectrum of fungal agents causing endophthalmitis from a single center, to identify the risk factors, and to correlate clinical course of illness with the agents involved. METHODS The microbiological and clinical records of all(More)
A Candida infection of the pancreas, which previously was considered extremely unusual, has been increasingly reported in recent years. The present study was conducted with the aim of performing a cohort analysis of our patients with acute pancreatitis to find out the incidence, sites, and species of Candida involvement; and to evaluate the risk factors,(More)
Objectives To identify the risk factors associated with Candida auris candidaemia, as this fungus now poses a global threat. Methods We performed a subgroup analysis of a previously reported study of 27 Indian ICUs. The clinical data of candidaemia cases due to C. auris and other Candida species were compared to determine significant risk factors(More)
BACKGROUND AND OBJECTIVES Fungal endophthalmitis is a devastating form of ocular infection and postoperative endophthalmitis following cataract surgery is the commonest form of such infection. Early diagnosis is very important for effective management of these patients. As conventional techniques take longer time and lacks sensitivity, polymerase chain(More)
We screened 194 Mycobacterium tuberculosis strains isolated from tuberculosis (TB) patients in Delhi and neighboring regions in India to identify the prevalence of extensive drug resistance (XDR) in clinical isolates. Among these, 104 isolates were found to be multidrug resistant (MDR), and 6 were identified as XDR isolates, which was later confirmed by(More)
Gram-positive pathogens mainly, Staphylococcus aureus, Enterococcus and coagulase-negative Staphylococcus, are developing increasing resistance to glycopeptides that pose a problem in treating infections caused by these pathogens. Vancomycin is the treatment of choice in treating methicillin-resistant S. aureus (MRSA). Community-acquired MRSA is associated(More)
All cases of cholera that have occurred at our center in north India have been due to Vibrio cholerae O1 serotype Ogawa, including the outbreaks in 2002 and 2004. Here we report the emergence of V. cholerae O1 biotype El Tor serotype Inaba for the first time in this region since July 2004. Fifteen Inaba isolates were obtained from 32 patients suffering from(More)
PURPOSE Paired blood culture (PBC) is uncommon practice in hospitals in India, leading to delayed and inadequate diagnosis. Also contamination remains a critical determinant in hampering the definitive diagnosis. OBJECTIVES To establish the need of PBC over single blood culture (SBC) along with the degree of contamination, this comparative retrospective(More)
Many countries have observed an increase in the incidence of invasive fungal infections (IFIs) over the past two decades with emergence of new risk factors and isolation of new fungal pathogens. Early diagnosis and appropriate antifungal treatment remain the cornerstones of successful outcomes. However, due to non-specific clinical presentations and limited(More)
