Resumo: | The genus Enterococcus belongs to the group of Gram-positive cocci, morphologically arranged in pairs or chains. It colonizes the human microbiota, mainly the gastrointestinal system. This genus has emerged as an important opportunistic pathogen causing community and nosocomial infections. The survive in the hospital environment is related to the presence of intrinsic resistance to many antibiotics, in addition to capabilities of resistance acquisition by mutation or mobile genetic elements. The aim of the study is to characterize phenotypic and genetically strains of vancomycin-resistant Enterococcus. Five strains from different hospitals were analyzed, it was collected from peripheral blood, anal swab, cerebrospinal fluid and purulent secretion. The isolates were identified at the species level by automated system VITEK 2. The resistance profile to antimicrobials was assessed by disk-difusion test, E-test and dilution in agar as recommended by the Clinical and Laboratory Stardards Institute, 2016. The genetic relationship between the strains were evaluated by the technique of Pulsed Field Gel Electrophoresis (PFGE). All strains were identified as Enterococcus faecalis and showed resistance to vancomycin, tetracycline, ciprofloxacin, as well as high levels of gentamicin and streptomycin. One sample had resistance to linezolida and all of them were sensitive to ampicillin and fosfomycin. The isolates had two distinct types, A and B, in which pulse A predominated in four strains. The emergence of resistance to vancomycin observed in this study may point to a possible change in the epidemiology of enterococcal infections in the city of Natal. |

Eles colonizam naturalmente o ser humano, principalmente o sistema gastrointestinal. Contudo, esse gênero vem emergindo como um importante agente patogênico oportunista causador de infecções, tanto comunitárias quanto hospitalares. A sua sobrevivência no ambiente hospitalar está relacionada com a presença da resistência intrínseca a diversos antimicrobianos, além da sua capacidade de aquisição de resistência por mutação ou por elementos genéticos móveis. O objetivo desse estudo é caracterizar fenotípica e geneticamente cepas de Enterococcus resistentes à vancomicina. Foram analisados cinco isolados provenientes de hospitais diferentes coletados de sangue periférico, swab anal, líquido cefalorraquidiano e secreção purulenta. Os isolados foram identificados no nível de espécie através do sistema automatizado VITEK 2. O perfil de resistência aos antimicrobianos comumente utilizados na clínica médica para o tratamento de infecções por Enterococcus foi avaliado por meio da técnica de disco-difusão, do E-test e da diluição em meio sólido, segundo recomendação do Clinical and Laboratory Stardards Institute, 2016. As relações genéticas foram avaliadas pela técnica da eletroforese em campo pulsado (PFGE). Todas as cepas foram identificadas como Enterococcus faecalis e apresentaram resistência à vancomicina, tetraciclina, ciprofloxacina, assim como a altos níveis à gentamicina e à estreptomicina. Uma amostra apresentou resistência à linezolida e todas foram sensíveis à ampicilina e à fosfomicina. Os isolados apresentaram dois pulsotipos distintos, A e B, no qual o pulsotipo A predominou em quatro cepas. A emergência da resistência à vancomicina observada nesse estudo pode apontar para uma possível mudança na epidemiologia das infecções enterocócicas na cidade do Natal.Universidade Federal do Rio Grande do NorteUFRNBrasilBiomedicinaEnterococcus faecalis;Enterococcus faecalisVREVREResistência à vancomicinaVancomycin-resistantCNPQ::CIENCIAS BIOLOGICAS::MICROBIOLOGIA::MICROBIOLOGIA MEDICAEmergência de Enterococcus resistente à vancomicina na cidade do Natal/RNinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccessporreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNTEXTEmergenciaEnterococcus_Oliveira_2016.pdf.txtExtracted texttext/plain57131https://repositorio.ufrn.br/bitstream/123456789/43263/1/EmergenciaEnterococcus_Oliveira_2016.pdf.txt942c1b7cbde2193dd0f096336f93faceMD51EmergênciaEnterococcusResistente_Oliveira_2016.pdf.txtExtracted texttext/plain57131https://repositorio.ufrn.br/bitstream/123456789/43263/2/Emerg%c3%aanciaEnterococcusResistente_Oliveira_2016.pdf.txt942c1b7cbde2193dd0f096336f93faceMD52LICENSElicense.txttext/plain756https://repositorio.ufrn.br/bitstream/123456789/43263/3/license.txta80a9cda2756d355b388cc443c3d8a43MD53ORIGINALEmergênciaEnterococcusResistente_Oliveira_2016.pdfMonografiaapplication/pdf4754438https://repositorio.ufrn.br/bitstream/123456789/43263/4/Emerg%c3%aanciaEnterococcusResistente_Oliveira_2016.pdf960784b197b7b45b9db8fc0edd04e475MD54123456789/432632021-10-06 08:18:17.084oai:https://repositorio.ufrn.br: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ório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2021-10-06T11:18:17Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false |
