Diversity of environmental and patients bacteria in the Hospital Geral de Palmas-TO / Diversidade de bactérias ambientais e de pacientes no Hospital Geral de Palmas-TO.

Abstract

Resistant pathogens are an important challenge to hospitals, especially to stablish the correct treatment and prophylactic measures. Once in the environmental Gram-negative strains can acquire resistance genes from the soil, water and hospital effluent and so transmit it to other genus. The objective of this study was to quantify and to qualify the bacterial strains present in patients with suspected of nosocomial infection and the environment in which they are admitted in the Palmas General Hospital. 14 different bacterial species from 141 samples, being 123 from patients and 18 from hospital environment. In patient samples highlights were Klebsiella pneumoniae (21.9%), Acinetobacter baumannii (13.82%), Pseudomonas aeruginosa (12.2%), Escherichia coli (11.4%), Serratia marcescens (10.6 %) and Staphylococcus aureus (9.0%), From this total, 80 strains were multiresistant to antibiotics, whichever Klebsiella pneumoniae (26.3%) and A. baumannii (20.0%). The tracheal aspirate samples showed a greater number of multidrug-resistant strains. The environment prevailed Serratia marcescens, Staphylococcus aureus and Staphylococcus sp. both with 22.2%, collected from different locations and ICU materials such as tracheal tube, Ambu, mattress and monitors. Administrative and educational strategies are necessary to reduce the spread of multi-resistant germs.
