Microbiological analysis of bioaerosols collected from Hospital Emergency Departments and ambulances

Abstract

Introduction and objective. The goal of the study was a microbiological, qualitative and quantitative analysis of bioaerosol at the workplace of medical personnel (Health Emergency Departments (HEDs), ambulances), and comparative administration offices with an expected neutral occupational exposure to biological agents measured with individual Button Sampler. Materials and method. Personal sampling was performed with Button Sampler instrument loaded with gelatine filters in 10 HEDs, in 9 ambulances and in 9 offices to assess the occupational biological agents' exposure in air. Sampling was conducted from March until April 2016. Samples were quantitatively assessed for viable and total number of bacteria and fungi. Routine procedures for microbiological diagnostics were implemented. Data were analysed using Kruskal-Wallis and Mann-Whitney statistical tests with α=0.05. P value less than 0.05 were considered significant. Results. At the workplaces assessed, the concentrations of viable microorganisms in HEDs were 1.3 × 10 2 -4.2 × 10

“…Surface contamination can also be caused by bioaerosols emitted by infected patients or contaminated equipment. However, airborne biological hazards are a concern for human health [16,17].…”

Exposure and Health Effects of Bacteria in Healthcare Units: An Overview

“…S. aureus was also prevalent in the studies by Matinyi et al [38] and Thomas et al [73], being detected on door handles, which could be considered a possible source of nosocomial infection [38]. Additionally, Staphylococcus epidermidis, as well as Micrococcus luteus and Bacillus subtilis, were common in the studies by Sivagnanasundaram et al [50], Bielawska-Drózd et al [74], and Bolookat et al [39]. The reason for these results could be related to the presence of these bacteria in the skin, mucous membranes, hair of human beings and animals [75][76][77][78].…”

Avaliação Dos Microrganismos Viáveis Potencialmente Patogênicos Em Bioaerossóis Em Uma Unidade De Terapia Intensiva

“…Os bioaerossóis são partículas transportadas pelo ar, constituídos por bactérias, vírus, fungos e parasitas, que invadem o corpo humano por via aérea, via oral e transcutânea (MIRHOSEINI et al, 2015;BIELAWSKA-DRÓZD et al, 2018;SIVAGNANASUNDARA et al, 2019). As partículas transportadas pelo ar têm alto significado em diferentes partes dos hospitais.…”

“…Existe uma gama de microrganismos potencialmente patogênicos associados a infecções hospitalares, muitos dos quais são patógenos oportunistas que frequentemente causam infecções respiratórias, particularmente em pacientes imunocomprometidos. Para determinar a extensão do problema, faz-se necessário realizar amostragens para verificar e quantificar a presença de bioaerossóis, dado que a microbiota pode variar entre diferentes UTIs e as assinaturas microbianas relacionadas às doenças infecciosas transmitidas pelo ar nessas unidades permanecerem pouco exploradas (BIELAWSKA-DRÓZD et al, 2018;RIBEIRO et al, 2019). Nesse contexto objetivou-se na presente pesquisa avaliar a presença de microrganismos viáveis potencialmente patogênicos em bioaerossóis de uma Unidade de Terapia Intensiva de um hospital do noroeste paulista.…”
