<i>Streptococcus agalactiae</i> Serotype VII, an Emerging Pathogen Affecting Snakeskin Gourami (<i>Trichogaster pectoralis</i>) in Intensive Farming.

ABSTRACT: Snakeskin gourami (Trichogaster pectoralis) is a freshwater fish species that is being increasingly cultivated in Southeast Asia. The expansion of farms and intensive farming practices has led to the unexplained mortality of snakeskin gourami and tremendous economic losses in many farms.
