N2  - The  O1 serogroup is responsible for pandemic cholera and is divided into the classical and El Tor biotypes. Classical  produces acid when using glucose as a carbon source, whereas El Tor  produces the neutral product acetoin when using glucose as a carbon source. An earlier study demonstrated that  strains that metabolize glucose to acidic by-products drastically reduced the survival of  strains in vitro. In the present study, zebrafish were fed 1% glucose and inoculated with single  or  strains or co-infected with both  and  A significant decrease in classical biotype colonization was observed after glucose feeding due to acid production in the zebrafish intestine. El Tor colonization was unaffected by glucose alone. However, the El Tor strain exhibited significantly lower colonization of the zebrafish when either of the acid producing  was co-inoculated in the presence of glucose. An  sugar transport mutant had no effect on  colonization even in presence of glucose. Glucose and  produced a prophylactic effect on El Tor colonization in zebrafish when  was inoculated before  infection. Thus, the probiotic feeding of  inhibits  colonization in a natural host. This suggests that a similar inhibitory effect could be seen in cholera patients, especially if glucose-based oral rehydration solution (ORS) is administered in combination with probiotic  during cholera treatment.
