Microbiota fúngica do ambiente da UTI neonatal e de amostras clínicas dos recém-nascidos internados no Hospital Universitário de Maceió, AL

Abstract

The fungi are being opportunistic, with wide distribution in nature, including the hospital environment, where it is frequent the presence of microorganisms that cause hospital infection, especially in immunocompromised patients. To identify and quantify the fungal microbiota in air, the filters of air-conditioners and samples of newborns from the neonatal ICU at University Hospital / HUPA, Maceió, Alagoas. Were held 20 exhibitions of collections totaling 400 disposable Petri dishes containing Sabouraud agar medium plus antibiotic. The plates were placed randomly inside and open the two neonatal ICUs (A and B) for 20 minutes. Also, there were 20 samples of the filters of air-conditioners of neonatal ICUs and conducted the direct examination and culture of clinical samples from newborns. CFU were isolated in 1209, these 675 (55.8%) were isolated CFU before cleaning to be done in the neonatal ICU and 534 (44.2%) CFU obtained after cleaning. Of 697 CFU of the environment of the NICU, 372 were isolated before and 325 after cleaning. Environment B, were obtained of 512 CFU and 303 CFU were obtained before cleaning and 209 after UFC. During the study species of Cladosporium was the most representative in the air and in the filters of air-conditioners. The clinical sample was more representative urine with 79.5%. Among the identified yeast Candida parapsilosis was present in 38.9% of environmental isolates of yeast and Candida albicans was isolated in 20% of clinical samples of newborns. The presence of pathogenic fungi in the two environments of the neonatal ICU and clinical samples of infants, demonstrating the need for constant monitoring to take control of microorganisms in hospital environments, especially in intensive care units where there is the presence of immunocompromised patients prone to develop fungal infections.
