Nosocomial infection is the one of the most important problems which remain to be solved especially for the immunocompromised hosts. Environmental factors are first of all to be considered in hospital acquired infection.
Microbiological monitoring has been conducted in hospital environment such as air, floor, and in foods for the patients, in medical personels and relatives who intimately care for the patients.
1) In air cultured bacterial counts are 21 of Coagulase-negative Staphylococci, in floor 7 of alpha-hemolytic streptococci, in sink faucet 400 of Micrococci, in sink drain 49 of P. aeruginosa, in tap water 3 of Coagulase-negative Staphylococci, in door knob 11 of Micrococci.
2) 103/g of A. calcoaceticus are cultured in young radish soup, 105~106/mL of Bacillus in Mul-Kimchi(watery kimchi), 106~107/mL of Lactobacillus in Chop suey, but in potato-soup, roasted mushroom no microorganisms are identified.
3) Coagulase negative Staphylococci are cultured from fingertips of medical personnels, gamma hemolytic Streptococci and Corynebacteria are from nostrils. Enterococci and Coagulase negative Staphylococci are cultured from fingertips of the relatives, nonhemolytic Streptococci are from nostrils, alpha hemolytic Streptococci and N. pharyngitidis are from the throats.
