Resumo: | Introduction: The toxigenic Vibrio cholerae, which causes Cholera, have a defined environmental tolerance regarding pH, temperature and salinity which does not prevent it from entering viable-but-nonculturable (VBNC) state, when the ranges of these parameters are not favorable. Port areas are vulnerable places for pathogen introduction, due to the contribution of urban effluents and the disposal of ballast water. Objective: The work evaluated whether the port of Rio de Janeiro present pH, salinity and temperature conditions that allow the microorganism establishment. Method: Twenty-two monitoring campaigns were carried out in 9 points, from March 2017 to February 2018, always searching for different climatic and tidal conditions. Results: The tide had a slight influence on the salinity, while the climate interacted with all the factors. The temperature and pH remained within the optimal range for the pathogen establishment, while the salinity was outside the ideal range most of the times. Conclusions: Analyzing only these factors, we can suggest that, if these standards are maintained, the region could present a risk of the microorganism survival. |

As zonas portuárias são áreas vulneráveis de introdução do patógeno, devido ao aporte de efluentes urbanos e descarte de água de lastro. Objetivo: O trabalho avaliou se as águas portuárias da cidade do Rio de Janeiro apresentam condições de pH, salinidade e temperatura que possibilitam o estabelecimento do microrganismo. Método: Foram realizadas 22 campanhas de monitoramento em nove pontos, no período de março de 2017 a fevereiro de 2018, buscando sempre diferentes condições climáticas e de maré. Resultados: A maré apresentou ligeira influência na salinidade, enquanto o clima interagiu com todos os fatores. A temperatura e o pH se mantiveram dentro da faixa considerada ótima para o estabelecimento do patógeno, enquanto a salinidade se apresentou, na maioria das vezes, fora da variação ideal. Conclusões: Analisando somente estes fatores, podemos sugerir que, caso estes padrões se mantenham, a região apresenta um risco de sobrevida do microrganismo.Instituto Nacional de Controle de Qualidade em Saúde2019-02-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion"Peer-reviewed article""Artículo revisado por pares""Artigo avaliado pelos pares"application/pdfapplication/pdfhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/115410.22239/2317-269X.01154Health Surveillance under Debate: Society, Science & Technology ; Vol. 7 No. 1 (2019): February; 14-22Vigilancia en Salud en Debate: Sociedad, Ciencia y Tecnología; Vol. 7 Núm. 1 (2019): Febrero; 14-22Vigil Sanit Debate, Rio de Janeiro; v. 7 n. 1 (2019): Fevereiro; 14-222317-269Xreponame:Vigilância Sanitária em Debateinstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZporenghttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/1154/985https://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/article/view/1154/1068Copyright (c) 2019 Vigilância Sanitária em Debate: Sociedade, Ciência & Tecnologia (Health Surveillance under Debate: Society, Science & Technology) – Visa em Debatehttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSilva, Everaldo de SantanaFernandez, Marcos Antonio dos SantosLopes, Amanda PontesCosta, Bárbara SilvaPereira, Sidharta SoaresPereira, Matheus Ventura2023-06-27T16:49:42Zoai:ojs.visaemdebate.incqs.fiocruz.br:article/1154Revistahttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebatePUBhttps://visaemdebate.incqs.fiocruz.br/index.php/visaemdebate/oaiincqs.visaemdebate@fiocruz.br || gisele.neves@fiocruz.br2317-269X2317-269Xopendoar:2023-06-27T16:49:42Vigilância Sanitária em Debate - Fundação Oswaldo Cruz (FIOCRUZ)false |
