BACKGROUND & OBJECTIVES There has been a resurgence in the incidence of rheumatic heart disease all over the world and hence surveillance and strain characterization are important. The aim of this study was to screen children in a rural community in south India for throat carriage of group A streptococci and to clinically assess them for signs of rheumatic(More)
OBJECTIVE The present study was undertaken to detect the prevalence of the blaNDM-1 metallo beta lactamases (MBLs) in the isolates of Pseudomonas aeruginosa, which were recovered from various clinical samples from hospitalized patients in a tertiary care centre in Pune, India. METHODS A total of 200 isolates of P. aeruginosa which were obtained from(More)
The genus Raoultella is composed of Gram-negative, aerobic, oxidase-negative, catalase-positive, nonmotile, capsulated rods belonging to the Enterobacteriaceae family (1). Raoultella ornithinolytica is found in aquatic and hospital environments (2). Occurrence of Raoultella in human infections is rare, but it has been reported to cause bloodstream and soft(More)
Thirty-eight isolates of group A streptococci from patients with pharyngitis, 13 isolates from patients with pyoderma and 28 carrier strains were subjected to biotyping by carbohydrate fermentation tests and production of beta-glucuronidase. Biotype 10 was observed most frequently among clinical isolates and biotypes 3 and 4 were most common among carrier(More)
BACKGROUND & OBJECTIVES Beta haemolytic streptococci belonging to Lancefield group A, B, C and G cause a wide spectrum of clinical diseases. Hence there is a need for rapid and accurate typing of these strains. The present study was undertaken to evaluate the use of intact cell matrix assisted laser desorption/ionization time-of-flight mass spectrometry(More)
The M protein of group A Streptococcus (GAS) is the major virulence factor and is coded by the emm gene. The current serologic M typing methods are now being replaced by alternate means of M type deduction such as emm gene sequencing. This is the first report of emm types of GAS which are prevalent in south India. We found no marked preponderance of any(More)
Objective. To detect genes encoding carbapenem resistance among Enterobacter species in a tertiary care hospital in central India. Methods. Bacterial identification of Enterobacter spp. isolates from various clinical specimens in patients admitted to intensive care units was performed by routine conventional microbial culture and biochemical tests using(More)
OBJECTIVE To detect genes encoding carbapenem resistance in urinary isolates of Escherichia coli recovered from hospitalized patients in tertiary care centre in Pune, India. METHODS From Jan 2012 to Dec 2012, a total of 300 consecutive non-duplicate (one isolate per patient) clinical isolates of Escherichia coli were recovered from urine cultures of(More)
OBJECTIVE The objective of the following study is to detect genes encoding carbapenem resistance in Klebsiella pneumoniae sepsis outbreak in a neonatal intensive care unit (NICU). MATERIALS AND METHODS Antibiotic sensitivity test was performed by standard Kirby Bauer disc diffusion technique and minimum inhibitory concentrations of antibiotics was(More)
