background: this study aimed to investigate and compare the bacterial safety of handmade and commercial ready‑to‑use enteral feeding formulas used in an iranian teaching hospital. methods: in this experimental study, a total number of 70 samples (21 handmade formulas sampled at two sampling times, i.e. the time of preparation and 18 h after preparation, and 28 commercial ready‑to‑use formulas) ...

Rainwater itself is free from pathogens and contamination levels of stored rainwater are generally low if tanks are well protected with covers or lids but obvious sources of contamination of the rainwater runoff can originate from faecal matter deposited by birds, frogs, possums, rodents, and dead animals and insects, either on the roofs or in the gutters, or in the water tank itself. A number ...

BACKGROUND AND OBJECTIVES Microbiological follow-up is part of quality control of peripheral blood stem cell (PBSC) manipulation. DESIGN AND METHODS We prospectively studied microbiological cultures performed in 865 consecutive untreated autologous PBSC harvests from 348 patients. Our aim was to know the rate of microbiological contamination, the optimum moment to evaluate the sample and the ...

background: hemodialysis is a life-saving process used as a treatment for many patients sufferimg from renal failure. because of the large amount of water used in this process, contamination of hemodialysis water with microbial and harmful chemical pollutants is possible. therefore, considering standards of dialysis water is critical. the aim of this study was to investigate the microbiological...

The presence of bacteria and fungi in indoor air pose a serious problem from the point of view of health protection and environmental engineering. Precise determination of various groups of microorganisms indoors is necessary both to estimate the health hazard and to create standards for indoor air quality control. This is especially important in such densely populated facilities like education...

The aim of this study was to evaluate microbiological contamination levels of indoor air in some farm settings, including barns and dairy objects. The level of microorganism emissions from farm buildings into atmospheric air was also estimated. In the research a MAS-100 air sampler (MERCK) was used. It was revealed that the number of microorganisms in barns ranged between 1.7·10 8.8·10 for meso...

Since intensive poultry production is accompanied by as high as possible densities of birds within buildings, this exposes poultry house workers to elevated concentrations of bioaerosol that is mainly emitted by birds. Exposure to dust containing pathogenic microbial and parasitic agents may cause asthma, asthma-like syndrome, mucous membrane irritation, chronic bronchitis, and allergic alveoli...

The higher education sector represents a unique environment and it acts as work environment, learning for students, frequently, also home environment. aim of this study was to determine the microbial contamination (SARS-CoV-2, fungi, bacteria) in Higher Education Facilities (HEI) by using active passive sampling methods combining culture-based with molecular tools targeting Aspergillus section ...
