Abstract
Background: The study was planned to show the status of indoor microorganisms and the status of the reduction device in the military dog clinic.
Methods: Airborne microbes were analyzed according to the number of daily patient canines. For identification of bacteria, sampled bacteria was identified using VITEK¢ç2 and molecular method. The status of indoor microorganisms according to the operation of the ventilation system was analyzed.
Results: Airborne bacteria and fungi concentrations were 1000.6 ¡¾ 800.7 CFU/m3 and 324.7 ¡¾ 245.8 CFU/m3. In the analysis using automated identification system, based on fluorescence biochemical test, VITEK¢ç2, mainly human pathogenic bacteria were identified. The three most frequently isolated genera were Kocuria (26.6%), Staphylococcus (24.48%), and Granulicatella (12.7%). The results analyzed by molecular method were detected in the order of Kocuria (22.6%), followed by Macrococcus (18.1%), Glutamicibacter (11.1%), and so on. When the ventilation system was operated appropriately, the airborne bacteria and fungi level were significantly decreased.
Conclusion: Airborne bacteria in the clinic tend to increase with the number of canines. Human pathogenic bacteria were mainly detected in VITEK¢ç2, and relatively various bacteria were detected in molecular analysis. A decrease in the level of bacteria and fungi was observed with proper operation of the ventilation system.
