Description
Summary:	Bacterial bioaerosols agglomerate and transport into respirable microscopic particles more easily compared to other microorganisms. This is because air currents help their proliferation since they have a longer resistance time in the air, depending on the degree of penetration into the respiratory system and the species can generate greater harmful effects onhealth becoming harmless or deadly in people, depending on the type of bacterial bioaerosols transported. This research evaluated the composition and concentration of bacterial bioaerosols in a neonatal intensive care unit (NICU) in the city of Barranquilla, located in a highly complex medical care center. To this end, three sampling campaigns were carried out at two times (before and after the cleaning days) and five sampling points, according to the extension of the NICU. Samples were collected using a Six-stage Andersen Thermo Scientific waterfall impactor doing dualreplicas every five minutes. Next, the identification and antibiotic resistance of the families of bacteria present was performed with the automatedequipment BD Phoenix ™ 100. The highest concentrations of bacterial bioaerosols were presented in stages 5,6 and 4 of the impactor, associated with smaller particles that can reach deeper sections of the respiratory system. The bacteria found are summarized to eight large families Bacillus subtilis, Streptococcus gordonii, Staphylococcus aerous, Eikenella Corrodens, Pseudomonas aerugionsa, Shigella dysenteriae, Bacillus Cereus, Eikenella Corrodens. These families came out resistant to ampicillin, ceftarolin, gentamicin, among other antibiotics. The results obtained will serve as input to the health staff of the clinic, for the detection of pathologies associated with these microorganisms that could influence the development of nosocomial infections to the Labor staff of the NICU.
