ROMERO BOHORQUEZ, César Alberto; CASTANEDA ALVARADO, Diego Fernando  and  ACOSTA PENALOZA, Gloria Stella. Bacteriological air quality in a microbiology laboratory at the Distrital Francisco José de Caldas. University in Bogotá, Colombia. Nova [online]. 2016, vol.14, n.26, pp.103-111. ISSN 1794-2470.

Objective. Determine airborne bacteria in a teaching laboratory of microbiology at the Distrital University and establish the bacteriological quality of air which users are exposed. Methods. Air samples were taken by sedimentation technique. The recovered colonies were counted, macroscopic and microscopic characterized and culture in selective media. The isolates were identifies by BD BBL Crystal. Results. It was found greater counts of gram-positive bacteria compared with Gram negative. It was identified bacteria of genus Micrococcus, Staphylococcus, Leuconostoc, Bacillus, Corynebacterium, Pseudomonas, Yersinia, Serratia, Shigella, Klebsiella, Citrobacter and Acinetobacter. The results showed that the bacteria identified do not present high risk to healthy of users, but it is necessary to implement measures to reduce the bacterial presence. Additionally, in this way decrease possible impact in general health of its occupants.
