An assessment of the Sartorius MD8 microbiological air sampler
Journal of Applied Bacteriology, 1996Tests described in this paper show that gelatine membrane filters used in the MD8 microbiological air sampling system collected monodispersed aerosols between 0·7 and 1·0 μm containing viable Bacillus subtilis var. niger spores, with an efficiency of 99·

Comparison of the collecting efficiency of microbiological air samplers
Journal of Hospital Infection, 2004It is important to evaluate the prevention of nosocomial infections caused by airborne micro-organisms in healthcare facilities. For that purpose, the use of an air sampler is required. A comparison of the collecting efficiency of air samplers has not been studied so far using a single culture medium. Use of the same culture medium is necessary because

Auditing the microbiological quality of the air in operating theatres
The Bone & Joint JournalThe critical relationship between airborne microbiological contamination in an operating theatre and surgical site infection (SSI) is well known. The aim of this annotation is to explain the scientific basis of using settle plates to audit the quality of air, and to provide information about the practicalities of using them for the purposes of clinical

Microbiological indoor air quality in healthy buildings.
The new microbiologica, 2002There is a growing interest in indoor air quality for a better quality environment both at home and at work because many people spend at least 80% of their time indoors. The aim of our study was to evaluate the indoor concentration of airborne bacteria and fungi in a University auditorium, in an office of public buildings and in an apartment in the ...

Microbiological and chemical quality of indoor air in kindergartens in Slovenia
International Journal of Environmental Health Research, 2019The concentrations of microorganisms, aerosol black carbon and carbon dioxide (CO2) in indoor and outdoor air of two kindergartens were investigated during four seasons. The highest mean concentrations of aerobic mesophilic microorganisms in indoor air were detected in spring.

Microbiological studies of air in the operating room
Journal of Surgical Research, 1967Abstract Contamination of operating room air by bacterial organisms fluctuates in direct relationship to human activity in a given operating room. In a three-year study period, an overall clean wound infection rate of 3.14% occurred. Air contamination in operating rooms varied between 1.5 and 18.3 microorganisms per cubic foot, depending on the ...

Evaluation of microbiological air quality and of microclimate in university classrooms
Environmental Monitoring and Assessment, 2011The proliferation of air-diffused microorganisms inside public buildings such as schools, hospitals, and universities, is often indicated as a possible health risk. In this research, we have illustrated the results of an investigation realized to determine the health of the air in some university classrooms, both from a microbiological and a ...

MICROBIOLOGICAL CHARACTERISTICS OF THE AIR BLOWN BY WARM AIR HAND DRYERS
TAF Preventive Medicine Bulletin, 2005The aim of the study was to determine the microbiological characteristics of air blown from warm air hand dryers, and to compare findings with the microbiological characteristics of indoor air in which the dryer settled. Air samples was taken from different public places (shopping centers, restaurants and hospitals) and investigated for total viable ...

Microbiological Studies of a Laminar Air Flow Unit for Patients
Archives of Environmental Health: An International Journal, 1969A laminar air flow (LAF) unit consisting of two patient rooms has been installed for patients’ undergoing cancer chemotherapy. Air circulated through the room in a horizontal laminar flow pattern after passing a bank of high efficiency filters. All necessary patient facilities were provided in the room.

Sampling of Microbiological Contaminants in Indoor Air
1987Strategies for sampling airborne biogenic contaminants including fungi, bacteria, viruses, and protozoa should include specific considerations for each group and very often for different species within these groups. The determination of target pollutants and sampling strategy is based on preliminary investigation of the indoor environment by a walk ...
