Resumo: In recent years, the emergence of resistant pathogens has complicated the treatment of bacterial infections in livestock production as well as in the medical field, due to the development of resistance mechanisms by microorganisms. The objective of this study was to delineate the antimicrobial resistance profile of Salmonella spp. strains isolated from bivalve mollusks (oysters and mussels) and from estuarine environment water of two regions of Bahia, Brazil. Twenty-seven strains, 12 isolated from bivalve mollusks and 15 from estuarine water, were tested. Eight antimicrobial agents (phenicol, beta-lactams, tetracyclines, quinolones and fluoroquinolones classes) were used for a susceptibility test, Minimum Inhibitory Concentration (MIC) and extended-spectrum beta-lactamases (ESBLs) production. Isolates showed high susceptibility to the classes of antimicrobial agents tested, with resistance only to nalidixic acid (27%), ampicillin (25%) and tetracycline (25%). Bacterial resistance was of chromosomal origin and the multidrug resistance index (MAR) among isolates of shellfish (mussels in natura) was 0.25. The MIC was found to be 100 µg/mL, 500 µg/mL and 350 µg/mL to nalidixic acid, ampicillin and tetracycline, respectively. None of the isolates presented ESBLs production. The presence of multidrug-resistant and high MIC Salmonella spp. is being conveyed in extraction areas of bivalve mollusks in the State of Bahia, Brazil.

O objetivo deste estudo foi traçar o perfil de resistência antimicrobiana em cepas de Salmonella spp. isoladas de moluscos bivalves (ostras e sururu) e da agua de áreas estuarinas em duas regiões da Bahia, Brasil. Um total de 27 cepas previamente isoladas foram testadas, sendo 12 provenientes de moluscos bivalves e 15 de amostras de água. Para o teste de suscetibilidade foram utilizados oito agentes antimicrobianos (classes fenicóis, betalactâmicos, tetraciclina, quinolonas e fluoroquinolonas), Concentração Inibitória Mínima (CIM) e a produção de Betalactamases de Espectro Ampliado (ESBL). Os isolados apresentaram alta suscetibilidade as classes de antimicrobianos testadas, com resistência apenas ao ácido nalidíxico (27%), ampicilina (25%) e tetraciclina (25%). A resistência bacteriana era de origem cromossômica e o índice de multirresistência (MAR) entre os isolados de molusco (sururu in natura) foi de 0,25. A CIM encontrada foi de 100 µg/mL, 500 µg/mL e 350 µg/mL para o ácido nalidixíco, ampicilina e tetraciclina, respectivamente. Nenhum dos isolados apresentou produção de ESBL. A presença de Salmonella spp. multirresistente e com elevada CIM está sendo veiculada em áreas de extração de moluscos bivalves no Estado da Bahia, Brasil.Universidade Federal Rural do Semi-Árido2016-05-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/408810.1590/1983-21252016v29n222rcREVISTA CAATINGA; Vol. 29 No. 2 (2016); 450-457Revista Caatinga; v. 29 n. 2 (2016); 450-4571983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/4088/pdf_381Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessSilveira, Carla Silva daSousa, Oscarina Viana deEvangelista-Barreto, Norma Suely2023-07-19T14:03:16Zoai:ojs.periodicos.ufersa.edu.br:article/4088Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:12.795542Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
