An Analysis of the Contaminants on Otoscopes of Otolaryngology Residents: An Observational Study.

Unlabelled: The study was conducted to learn if the otoscope, a noncritical medical device, used by ENT residents harbor pathogenic organism. This study was conducted in a medical teaching hospital in India. Total of 38 otoscopes of ENT residents were examined after taking samples using sterile cotton swabs from otoscope speculum and otoscope head and both bacterial and fungal culture were studied.

A Cross-Sectional Study on Molecular Detection of cytotoxin-associated gene A and 16SrRNA Gene from Gastric Biopsy Specimens.

Introduction: The aim of the study is relative proportion of cytotoxin-associated gene A () virulence marker in isolates and gastric biopsy samples by polymerase chain reaction (PCR).

Methods: This cross-sectional study was conducted at a tertiary care hospital setting. Gastric biopsy tissues from 200 patients, suffering from upper gastrointestinal tract disorders, were examined for infection using methods, such as hematoxylin and eosin (H and E) staining, (), and gene PCR.

Clinical significance of various diagnostic techniques and emerging antimicrobial resistance pattern of Helicobacter Pylori from Gastric Biopsy Samples.

Background: There is no single technique that can meet the criteria in identification of Helicobacter pylori. The diagnosis is important asantimicrobial resistance is frequently observed and associated with treatment failure. The present study was conducted to evaluate diagnostic tests for identification of H pylori and to assess their antimicrobial resistance pattern.

Haemagglutination and siderophore production as the urovirulence markers of uropathogenic Escherichia coli.

A total of 160 strains of Escherichia coli isolated from urine of patients with clinically diagnosed urinary tract infection were included in the study and 50 faecal isolates of E. coli were studied. They were studied for virulence factors, namely mannose-resistant and mannose-sensitive haemagglutination (MRHA, MSHA) and siderophore production.
