Efficacy of Sanacore® against Streptococcosis and Franciselosis in Tilapia

01/27/2020

Tilapia tolerate adverse conditions and stressors better than most commercial aquaculture species. However, current rearing conditions (i.e. high densities, water temperature and quality, etc.) induce a stress level that is detrimental to the animal´s immune system and that, in combination with the presence of pathogens, results in disease outbreak. Streptococcosis and franciselosis are two bacterial diseases associated to temperature fluctuations during the summer and winter periods and that cause high mortality in tilapia culture. In a recent article published in Aquafeed (vol 12, issue 1, 2020), the efficacy of Sanacore® GM against these two bacterial diseases was demonstrated.

In vitro results showed reduced number of bacterial cells and changes in their morphology. In vivo data proved a growth promoting effect just after 20 days of supplementation as well as significant reductions in mortality of 32% and 17% against infection by against Streptococcus agalactiae and Francisella noatunensis subsp orientalis, respectively.

This article further demonstrates the preventive efficacy of Sanacore® against bacterial infection and some of its modes of action underlying these improvements.
