in order to investigate the microbiological safety of sanitary tissues made of recycled scrap papers in iran, random samples were taken for one year with the cooperation of the iranian standard and industrial research institute (karaj unit), of 44 types of sanitary tissues, two samples of each type including tissues, toilet papers and dippers as well as a control sample and their probable conta...

BACKGROUND Microbiological contamination of water in dental unit waterlines (DUWL) creates a risk of cross-infections, and is a source of biological risk factors in the work environment of a dentist. The aim of the study was to evaluate dentists' knowledge on DUWL microbiological contamination and the scope of activities/procedures they undertake to monitor it. MATERIALS AND METHOD The questi...

The microbiological quality of 75 private drinking water supply boreholes in Co. Cork, Ireland was assessed in order to determine the incidence of contamination and the potential pathways of such contamination. Microbiological analysis was carried out using the membrane filtration technique for the recovery of thermotolerant (faecal) coliforms. The sanitary protection of the supplies was evalua...

Microbiol. 10:567-571. 1962.-Over 10,000 airborne microorganisms, isolated from various areas of two hospitals, were characterized according to colonial and microscopic morphology and certain physiological reactions, inc...

local food production can be seen worldwide, and there are several local wisdoms on food production. there are many problems on local food production, including the problem of microbiological contamination, which is considered a great concern. the safety consideration is required. in the tropical world, the problem of local tropical food production should be specially discussed. there are many ...

Urban groundwater development was traditionally constrained by concerns about its quality. This study was conducted in the regions of La Ribera Alta and Ribera Baja and La Plana de Requena-Utiel of the Valencian Community (Valencia, Spain) where population density, demand for drinking water and agricultural activities are high. Groundwater bodies (GWBs) are regarded as management areas within e...

OBJECTIVE To determine the frequency of microbiological contamination of water in different water filtration plants in Islamabad. STUDY DESIGN Descriptive cross-sectional study. PLACE AND DURATION OF STUDY Water Filtration Plants (WFP) in different sectors of Islamabad, from April to September 2012. METHODOLOGY Water samples were collected in sterilized bottles according to the standard w...

To survey the microbiological contamination of laboratory mice and rats in Korea during a 5-year period, we monitored animals housed in mouse and rat facilities with either barrier or conventional systems. At barrier and conventional mouse facilities, the most important pathogen identified was mouse hepatitis virus (MHV), while Mycoplasma pulmonis was the most important pathogen at conventional...

Microbiological contamination is an important water-quality problem worldwide. Human impact on this category of contamination is significant and several human-related activities, and also the population explosion, have affected and are still affecting dramatically the aquatic environment. Extensive industrialization and agriculture have led to increased pollution and hydromorphological changes ...
