In this study presence of virulence genes in multidrug resistant isolated from Mula-Mutha river, Pune, India was undertaken. The objective was to understand whether the isolates were of diarrhoeagenic or of environmental origin. This was essential since the river flows through urban and rural parts of Pune and its water is used not only for industrial and agricultural purposes but also for domestic usage.

The river Mula-Mutha in Pune District, India, is linked to a number of major drinking water sources in villages situated along its banks. This study assessed the seasonal variations in bacteriological water quality along the Mula-Mutha river using Thermotolerant Faecal Coliforms (TFC) as indicator bacteria for faecal contamination as per the WHO standard guidelines for drinking water. Eight points were chosen based on a survey carried out focusing on different sources of contamination which may influence water quality.

The DDR were further examined for antibiotic resistance to six additional antibiotics. The study also included detection of genes responsible for ceftazidime and ciprofloxacin resistance and vectors for horizontal gene transfer.

The WHO has assigned high priority to the development of non-sputum diagnostic tools. We therefore sought to identify transcriptional signatures in whole blood of Indian children, capable of discriminating intra-thoracic TB disease from other symptomatic illnesses.

This study aimed to determine the genes coding for ESBLs, plasmid mediated quinolone resistance and virulence markers in commensal E. coli isolated from healthy school children.

Reduced frequency of indeterminate results and an increased sensitivity for tuberculosis suggest a potential for fewer missed cases with a combined IFNγ/inducible protein 10 read-out in a 4th generation IFNγ release assays.

Our aim was to explore perceptions of staff of an Indian rural tertiary care teaching hospital on hospital waste management.
Method: A qualitative study was conducted using 10 focus group discussions (FGDs), with different professional groups, cleaning staff, nurses, medical students, doctors and administrators.
Background: Appropriate hand hygiene is a gold standard to combat healthcare associated infections (HAIs). The World Health Organization (WHO) has recommended alcohol based hand rub (ABHR) as the most effective tool to maintain hand hygiene. In resource poor settings commercially available ABHR is not "economically accessible".

Methods And Results: Wastewaters from a rural (H1) and an urban (H2) hospital were tested for E. coli resistant to cephalosporins, carbapenem and quinolones.
Background: Commensal Escherichia coli are a prominent reservoir of genes coding for antibiotic resistance and also responsible for endogenous infections in pregnant women. We studied the factors in pregnant women associated with carriage of multi-drug resistant (MDR) E. coli and genetic determinants of antibiotic resistance in them.

This study analysed a South-east Indian population as part of the debate about the relevance of dupA for the prediction of clinical outcomes. A total of 140 H.

Methods: We prospectively collected consecutive, clinically significant, and nonduplicate bacterial isolates from each patient from two hospitals in Ujjain, India.
Carbapenem resistance among clinical isolates of Enterobacteriaceae, especially Escherichia coli and Klebsiella pneumoniae, is largely conferred by metallo-β-lactamase (MBL). Fifty-one non repetitive isolates of carbapenem-resistant (Meropenem and Imipenem) E. coli and K.

Aim: To explore staff perceptions of hand hygiene using focus group discussions (FGDs) in a teaching hospital in India.
Methods: Qualitative study.
Objectives: To investigate the presence of antibiotic resistance genes (ARGs), related to commonly used β-lactams and quinolones, in Escherichia coli present in hospital wastewater in central India.
Methods: Cefotaxime- and ciprofloxacin-resistant E. coli isolates from hospital-associated wastewater samples were collected from two tertiary care hospitals in the Ujjain district of India during 2008-09.
Background: There is increasing evidence that community acquired S. aureus infections are spreading among healthy children. Nasal colonization with S.

Extended spectrum beta lactamase (ESBL) associated resistance among Acinetobacter species is now known. The aim of this study was to speciate clinical isolates of Acinetobacter, analyze their resistance patterns, identify the production ESBLs and compare the role of different cephalosporins in detecting ESBL production in the isolates.

Hepatitis E virus is recently recognised as an important cause of non-A, non-B hepatitis. A total of 569 serum samples were screened for HEV between April 1997 and March 2000, by a commercially available HEV IgM capture ELISA. The diagnosis was invariably acute viral hepatitis for differential diagnosis of jaundice.

Purpose: To study the occurrence of Uropathogenic Escherichia coli (UPEC) in cases with urinary tract infections.
Methods: A total of 220 cases from urinary tract infections and 50 stool samples from apparently healthy individuals were included. The colonies identified as Escherichia coli were screened for virulence factors namely haemolysin, Mannose Resistant and Mannose Sensitive Haemagglutination (MRHA, MSHA), Cell surface hydrophobicity and Serum resistance by recommended methods.
Malnutrition is thought to potentiate the polyclonal stimulation of IgE by parasites. This diminishes immunity due to the decrease in specific anti-parasitic IgE. Prevalence of intestinal parasitic infections in chronically undernourished, asymptomatic adult males from a slum and efficacy of anti-parasitic therapy and its effect on total serum IgE were evaluated.

After his return to Bangalore, India, the patient developed intermittent fever of moderate to high grade, cough, loss of weight and appetite, and abscesses in the left cubital fossa and thigh regions. Systemic examination at our hospital revealed that he had dullness to percussion over the chest region and decreased breath sounds.
