OBJECTIVES Aerosols generated during dental procedures have been reported to contain endotoxin as a result of bacterial contamination of dental unit water lines. This study investigated the determinants of airborne endotoxin exposure in dental healthcare settings. METHODS The study population included dental personnel (n = 454) from five academic dental(More)
Legionella released into the air during treatment are a potential source of infection. Water stagnation in dental unit waterlines (DUWLs) creates biofilms and promotes the proliferation of these micro-organisms. This study investigated the presence of amoeba infected with legionella, L. pneumophila and other pathogenic Legionella species in a dental(More)
INTRODUCTION Fine aerosolised droplets and splatter generated during dental procedures influences the composition of the indoor air quality of dental care facilities and poses a potential threat to the workers' health. Therefore there is a need to assess the risks from exposure to bioaerosols and splatter and identify measures of reducing possible hazards.(More)
BACKGROUND Paragonimus has emerged as an important parasitic zoonosis in recent years in Manipur, India. However, no scientific data on the systematic and phylogenetic classification of lung fluke in India is available. Therefore, a study was conducted to determine the species of lung fluke prevalent in Manipur by infecting an experimental animal with(More)
BACKGROUND Contamination of water, food, and environment with antibiotic-resistant bacteria poses a serious public health issue. OBJECTIVE The objective was to study the bacterial pollution of the natural sources of water in east Sikkim and to determine the antimicrobial profile of the bacterial isolates. MATERIALS AND METHODS A total of 225 samples, 75(More)
The application of occupational health and safety (OHS) legislation in the dairy industry varies throughout the world. Generally there is no specific OHS legislation that applies to the dairy industry and mostly in countries the current OHS legislation applies to all workplaces with specific guidelines that apply to agricultural industries. The main(More)
This review outlines and compares techniques that are currently available for the sterilization of nanoparticles and addresses the topic of endotoxin contamination. Several techniques are available for the removal of microbial contamination from nanoparticles developed for use in nanomedicine applications. These techniques include filtration, autoclaving(More)
PURPOSE To determine the prevalence of paragonimiasis among the patients who were attending the tuberculosis (TB) clinics at the Community Health Centre, Pfutsero, Phek District, Nagaland. To determine the species of Paragonimus that cause infection in humans and the crustacean host that acts as the infectious source for humans. MATERIALS AND METHODS(More)
BACKGROUND Airborne transmission of Mycobacterium tuberculosis remains an occupational health hazard, particularly in crowded and resource-limited healthcare settings. AIM To quantify airborne M. tuberculosis in a busy outpatient clinic in Gauteng, South Africa. METHODS Stationary air samples and samples from healthcare workers (HCWs) were collected in(More)
The aim of this study was to analyze the phylogenetic relationship between Explanatum explanatum populations in India and other countries of the Indian subcontinent. Seventy liver amphistomes collected from four localities in India were identified as E. explanatum based on the nucleotide sequences of ribosomal ITS2. The flukes were then analyzed(More)
