Enterobacteriaceae ISOLATES FROM THE ORAL CAVITY OF WORKERS IN A BRAZILIAN ONCOLOGY HOSPITAL

“…A similar study performed with 278 members of a healthcare team at a university hospital found a 69.6% colonization rate by gram-negative bacteria (GNB) (enterobacteria and/or non-fermenters) 20 . In studies with immunocompromised individuals, the presence of Enterobacteriaceae in the oral cavity varied from 32.5% to 60.7% 10 , 21 .…”

“…Another concerning factor is that 9.1% of the carriers were colonized by different species of enterobacteria. In one study performed with the healthcare team of a teaching hospital, 49.2% of the workers were multicolonized by GNB 20 . The large microbial diversity of the oral cavity reflects, among other factors, the presence of the dental biofilm, which enables special conditions for survival and growth 14 .…”

“…In regard to the phenotypic characterization of the isolated microorganisms, the most common bacteria were Enterobacter , Klebsiella and Citrobacter , and the most prevalent species was Enterobacter gergoviae (17.2%). In one study with health workers, the genera Enterobacter and Klebsiella were also described as the most frequent in the oral cavity 20 . Similar data were reported in another study, in which Enterobacter cloacae (31.0%) was the most isolated enterobacteria among individuals in dental treatment, followed by Klebsiella pneumoniae (18.3%) 24 .…”

Pseudomonas spp. ISOLATED FROM THE ORAL CAVITY OF HEALTHCARE WORKERS FROM AN ONCOLOGY HOSPITAL IN MIDWESTERN BRAZIL

“…However, studies of the oropharyngeal colonization of healthcare professionals by Pseudomonas spp. are scant and the relevance of these carriers should be enlightened 3 , 4 , 11 , 12 . This research aimed to determine the prevalence of oral colonization and the antimicrobial susceptibility of Pseudomonas spp.…”

Trabajadores del área de salud de un hospital oncológico colonizados por microorganismos multidroga resistentes

“…De acuerdo con la cadena epidemiológica de infección, gotículas de saliva cargadas de microorganismos virulentos pueden constituir una fuente de contaminación cruzada y, consecuentemente, provocar la colonización de pacientes y trabajadores. Dicho mecanismo condiciona la diseminación de tales agentes, tanto en el ambiente hospitalario como en la propia comunidad 12 . De este modo, identificar profesionales del área de salud colonizados por microorganismos se configura como un riesgo para la seguridad de los pacientes 13 .…”
