Antimicrobial resistance profile of Aeromonas spp. isolated from asymptomatic Colossoma macropomum cultured in the Amazonas State, Brazil.
Bacterial diseases are important factors that limit productivity in aquaculture. To reduce negative economic impacts, fish farmers use antimicrobials, often indiscriminately, and this action has led to bacterial resistance to drugs. The objectives of this study were to isolate and identify the main putative pathogenic bacterial species in tambaqui (Colossoma macropomum), establish the profile of resistance to antimicrobials by the methods of disc diffusion, and determine the minimum inhibitory concentration (MIC) values. Two hundred and ninety asymptomatic fish were collected between March and November 2015 from ten fish farms in the Amazonas state (Brazil). As doenças bacterianas são fatores importantes que limitam a produtividade na aquicultura. Para reduzir os impactos econômicos negativos, os piscicultores utilizam antimicrobianos, muitas vezes de forma indiscriminada, e essa ação tem levado à resistência bacteriana aos medicamentos. Os objetivos deste estudo foram isolar e identificar as principais bactérias com potencial putativo para o tambaqui (Colossoma macropomum), e estabelecer o perfil de resistência a antimicrobianos pelos métodos de difusão em disco e valores de concentração inibitória mínima (CIM).
