“…That's what happened to S. agalactiae, whose adaptive behavior makes S. agalactiae virulent and deadly. Zhao et al [71] demonstrated that high temperatures can change the gene expression of S. agalactiae and that tilapia become more susceptible to S. agalactiae infection in terms of the host.…”

Due to their poikilothermic nature, fish are very sensitive to changes in temperature. Due to climate change, the average global temperature has increased by 1.5°C in the last century, which may have caused an increase in farmed fish mortality recently. Predictions using the model estimate that a 1°C increase in temperature could cause 3%-4% and 4%-6% mortality due to infectious diseases in organisms living in warm and temperate waters, respectively. There is a need to determine whether there is a relationship between increasing environmental temperature and disease virulence. This review examines the influence and impact of increasing temperatures due to climate change on the physiology and pathogenicity of Streptococcus agalactiae, which causes streptococcosis in tilapia and causes significant economic losses. Changes in the pathogenicity of S. agalactiae, especially its virulence properties due to increasing temperature, require changes in the composition design of the fish vaccine formula to provide better protection through the production of protective antibodies. Keywords: adaptation, microbes, pathogen, temperature, virulence.
