Detecção de Aeromonas spp. e do gene de virulência aerolisina em tilápias do Nilo (Oreochromis niloticus) com a técnica de mPCR

Abstract: RESUMO: As infecções causadas por bactérias do gênero Aeromonas estão entre as doenças mais comuns em peixes cultivados em todo o mundo, com ocorrência de aeromoniose em todos os países que possuem cultivo de tilápia do Nilo (Oreochromis niloticus). O presente trabalho descreve o desenvolvimento de uma nova multiplex PCR (mPCR) para diagnóstico de Aeromonas spp. e identificação do gene aerolisina (aerA). Para padronização da mPCR foram utilizadas cepas de referência de várias espécies do gênero Aeromonas e de … Show more

“…Molecular techniques such as polymerase chain reaction (PCR) have advantages over conventional microbiological identification methods, such as rapid diagnosis and specificity for the investigated agent (ABU-ELALA et al, 2015), as well as the use of this technique allows the study of virulence factors of the strains, allowing to determine the potential degree of pathogenicity of a strain of interest (kIM et al, 2018). Several virulence factors have been described as important in the pathogenesis of infections caused by Aeromonas spp., among the most studied are aerolysin (AerA), cytotoxic enterotoxin (Act), and cytotonic enterotoxin (Ast).…”

“…The impact of these bacteria must be considered since several researchers affirm that the exposure to the aquatic ecosystem and its habitats can be precursors of diseases caused by Aeromonas and Edwardsiella (KIM et al, 2018;WIEDENMAYER;GILBERT, 2006). These are facultative pathogens that target hosts weakened or affected by other etiological agents, identified as secondary invaders, and establish themselves in the same way as other bacterial, viral, or parasitic infections, as well as those caused by nutritional or stress-related factors (BOTREL et al, 2010;MACHADO, TAKEMOTO, 1997).…”
