Hospital airborne microbial pollution in a desert country

Distribution Characteristics of Airborne Bacteria and Fungi in the General Hospitals of Korea

“…This finding is in agreement with previous report by Jaffal et al 13) that pathogenic microorganisms showed less than 1% of the total count of bacteria isolated in the air of general hospital. However, they addressed that largest quantities of isolated bacteria were unidentified unlike pattern of predominant bacteria demonstrated from the study.…”

“…and Alternaria spp. by Jaffal et al 13) ; Aspergillus, Penicillium and Fusarium by Wu et al 20) ; and Penicillium by Li and Hou 15) , therefore, implicating that there is little difference between this result and previous reports.…”

“…The finding that the level of airborne bacteria was higher than airborne fungi was consistent with the previous study by Li and Hou 15) . Possible explanation for that concentration of airborne bacteria and fungi was the highest in main lobby compared to other different types of hospital area would be frequent comings and goings of many people based on the report by Jaffal et al 13) that bioaerosol level in hospital is determined mainly by human activity. On the other hand, the reason that the ICU had the lowest level of airborne microorganisms might be because it is a clean room applied with high ventilation rate.…”

“…In foreign countries, several studies regarding distribution characteristics of airborne microorganisms in hospital were performed previously [13][14][15] . There is, however, relatively little information for airborne microorganisms in general hospitals of Korea although social concerns as regards the healthcare-associated infections (HAI) become increasingly widespread.…”

Microbiological assessment of indoor air of a teaching hospital in Nigeria

“…Some of these clinical isolates have been reported by earlier researchers [8,9,20,21] . Staphylococcus aureus as the most frequently isolated bacterium from this study has been incriminated in various diseases such as post operative infections, urinary tract infections, skin infections, respiratory infections and food poisoning [22,23] .…”
