Abstract:
Objective To find out about the temperature ,relative humidity, concentration and species of air microbes in the warship , and to detect the possible pathogenic agents responsible for the high incidence of respiratory diseases among the crew.Methods A digital hygrometer was used to measure the indoor tempreture and relative humidity .Open agar set-tling plates were used to sample the air bacteria in the ship .Pure bacterial colonies were isolated from those on the original plates by repeated streak inoculation .The species of bacteria were determined by gram staining ,light microscope observation and 16S rDNA sequencing .Results Spots that met the standard requirement of temperature accounted for 20%but relative humidity was up to the stevrdard ineach place investigated .Although the concentration of airborne microbes was under the standard limit,bacteria were various.There were 18 different bacteria isolated from the air sample , including Chryseobacteri-um jejuense,Acinetobacter baumannii, Bacillus sporothermodurans, Staphylococcus aureus, Staphylococcus capitis, Staphylo-coccus hominis subsp.hominis strain and subsp.novobiosepticus, Staphylococcus cohnii subsp.cohnii and subsp.urealytic-us,Enhydrobacter aerosaccus,Corynebacterium casei,Macrococcus caseolyticus,Corynebacterium ammoniagenes,Brevibacillus panacihumi,Comamonas koreensis,Bacillus subtilis,Sphingobium yanoikuyae, Chryseobacterium hominis.Conclusion The high incidence of respiratory diseases among officers and soliders might be related to the lower tempreture and some airborne bacteria in the warship .
