Resistência Bacteriana Transportada Pelo Ar: Uma Abordagem Clínica

Abstract

The proliferation of bacterial resistance is a problem in health services. We analyzed the spread of airborne plasmid bacterial resistance in a Clinical School of Physiotherapy in the state of Piauí, Brazil. We evaluated the bacteriological quality of the air by sedimentation and profiled bacterial resistance by plasmid cure. In the analyzed points: reception (R), corridor (C), orthopedics gym (M) and neurology gym (N), bacterial concentrations were within the quality parameters. Points R and C showed the highest average amount of CFU/m3, possibly due to the people in circulation and ventilation. Of the isolates: 96.6% are Gram positive; 63.3% are cocci, 33.3% are rods and 3.3% are coccobacilli. Gram positive bacteria better withstand environmental stress. Cocci are part of the human microbiota. In all environments we identified strains resistant to at least one antibiotic. Point M presented 43% resistance and N, 44%; the two biggest. Ampicillin (45%) and sulfazotrim (42%) showed a high level of resistance. Seven different multiresistance profiles (MAR) were found. Strains N3, N7 and R9 have a MAR greater than 0.5. Plasmid resistance was identified in: N3, N4, N7, R1, R5 and R9. R and N had the highest number of multidrug-resistant strains (42.85%). Six isolates showed plasmid resistance and one with resistances potentially of complete chromosomal origin. Studies of this type should be encouraged so that we have knowledge about the scenario of the dissemination of resistance genes in this matrix. As well as contributing to the incorporation of the bacterial group in the national legislation.
