“…132 Moreover, Bacillus subtilis PP2 isolated from the estuarine fish gut of Chelon parsia exhibited potent antimicrobial activity against various bacterial and fungal pathogens. 133 Furthermore, antagonism against fish pathogens by commensal bacteria and its probiotic activity were evaluated. Notably, cellular components of Bacillus methylotrophicus, Bacillus subtilis subsp.…”

“…Specifically, the bacteria Lactococcus lactis TW34 isolated from Odontesthes platensis (Berg), is demonstrated to be a bacteriocin‐producing bacteria through the nisin Z antimicrobial peptide synthesis with an additional bactericidal mode action that inhibits the fish pathogen Lactococcus garvieae at 5 AU/ml (minimum inhibitory concentration) 132 . Moreover, Bacillus subtilis PP2 isolated from the estuarine fish gut of Chelon parsia exhibited potent antimicrobial activity against various bacterial and fungal pathogens 133 …”

The gut microbiota is currently one of the most studied 'organs' in animals, and fish are no exception. A complex diversity of microbes, including bacteria, archaea, yeast and fungus, constitute the gut microbiota, creating a complex interaction with their host and accomplishing multiple beneficial functions, such as food digestion, nutrient absorption, immune system, endocrine and stress response. The microbiotapathogen interaction protects the host by mounting colonization resistance, competing for nutrients and space. Changes in the balance of the microbiota community could affect their structure and homeostasis, inducing dysbiosis. In addition, invading pathogens can induce dysbiosis by evading the host's defence barriers, acquiring nutrients from the fish host, using metabolites produced by the microbiota and producing toxins. In this regard, understanding the interactions within the fish gut microbiota is essential to prevent pathogen establishment in the host. Hence, this review describes the close and indivisible relationships and interactions between gut microbiota and pathogens that could lead to dysbiosis and disease.
