AI Article Synopsis

  • Researchers studied mycobacterial infections in farmed yellowtail fish in western Japan, specifically in Kagoshima, finding Mycobacterium pseudoshottsii in six fishing ports between 2012 and 2013.
  • Phylogenetic analysis revealed that one strain shared similarities across multiple regions in Japan, indicating a possible nationwide distribution, while it remained distinct from strains in the Mediterranean and the U.S.
  • The study emphasizes the significance of bacterial genomic analysis for tracking the prevalence and transmission routes of M. pseudoshottsii, which can help in monitoring fish farms and preventing potential epidemics linked to global trade in fisheries.

Article Abstract

To investigate mycobacterial cases of farmed yellowtail fish in coastal areas of western Japan (Kagoshima, Kyushu), where aquaculture fisheries are active, Mycobacterium pseudoshottsii, the causative agent, was isolated from six neighboring fishing ports in 2012 and 2013. A phylogenetic ana-lysis revealed that the strains isolated from one fishing port were closely related to those isolated from other regions of Japan, suggesting the nationwide spread of a single strain. However, strains from Japan were phylogenetically distinct from those from the Mediterranean and the United States; therefore, worldwide transmission was not observed based on the limited data obtained on the strains exami-ned in this study. The present results demonstrate that a bacterial genomic ana-lysis of infected cases, a mole-cular epidemiology strategy for public health, provides useful data for estimating the prevalence and transmission pathways of M. pseudoshottsii in farmed fish. A bacterial genome ana-lysis of strains, such as that performed herein, may play an important role in monitoring the prevalence of this pathogen in fish farms and possible epidemics in the future as a result of international traffic, logistics, and trade in fisheries.
