INTRODUCTION AND OBJECTIVES Nosocomial infections, also known as hospital-acquired infections, has become one of the most important health problems in health care units worldwide. The presented study aims to determine the average amount of microorganism loads and to show that the atmospheres of the two hospitals can be a potential source regarding nosocomial infections. The effect of surface an...

Biofouling is one of the major issues in the power industry using seawater for cooling and other purposes. Presence of biological organisms such as bacteria and algae that could foul pipes and expensive equipments need to be managed from economical and safety point of view. Generally, the biofouling problem is aggravated in hot climate regions. Various means of disinfection processes are availa...

A large proportion of hospital-related infections are acquired and spread due to the direct contacts between patients and healthcare workers. Accordingly, proper infection prevention measures, and especially hand hygiene, are key to limit the spread of infections in nosocomial settings. However, healthcare workers frequently experience difficulties in complying strictly to hand disinfection pro...

Endoscopy-related infections are important contributors to nosocomial infections. Endoscope reprocessing according to standard guidelines ensures high-level disinfection and prevents endoscopy-related infections. Microbiological surveillance may help in monitoring the effectiveness of gastrointestinal endoscope disinfection. The process involves microbial cultures and non-culture methods such a...

Cryptosporidium parvum and Giardia lamblia are two of the most chlorine resistant microorganisms with notable adverse effects on humans. Our study shows that waters containing these two protozoa at low concentrations can be efficiently disinfected in continuous flow by using a commercial fibrous ceramic TiO(2) photocatalyst. The efficiency of the photocatalytic disinfection is largely enhanced ...

The paucity of proper sanitation facilities has contributed to the spread of waterborne diseases in many developing countries. The primary goal of this study was to demonstrate the feasibility of using a wastewater electrolysis cell (WEC) for toilet wastewater disinfection. The treated wastewater was designed to reuse for toilet flushing and agricultural irrigation. Laboratory-scale electrochem...

This random survey was to determine the flexible nasopharyngoscope disinfection practice employed by South African otolaryngologists and to establish whether a breach in the disinfection process exists. The study also aimed to identify organisms most likely to be transmitted via endoscopy and to propose a protocol for the disinfection of the flexible nasopharyngoscope. A questionnaire regarding...

Background The process of cleaning and disinfection of animal transport vehicles after unloading animals at the abattoir is a critical control point regarding proper hygiene. It is an important step regarding the biosecurity. In the present study, a status quo analysis of the currently performed cleaning and disinfection measures of animal transport vehicles was carried out at the vehicle washi...

A cheap method by which hospital blankets may be effectively disinfected (approximately 3d. per blanket) is described. A recommendation is made that blankets from the patients' beds be divided into: ;socially dirty' blankets to be laundered, possibly at infrequent intervals; and ;socially clean' blankets to be disinfected frequently. The wide range of a synthetic phenolic compound is described....
