The data suggest that the glucose is catabolized by a fully aerobic route. Rather than repressing hydrolytic enzymes which might be associated with pathogenic properties, glucose enhanced the specific activity of aminopeptidase, trypsin-like protease, acid and alkaline phosphatase and α-glucosidase in comparison with a control culture grown in a tryptone/thiamin medium. Thus, the supply of glucose could be of importance in maximizing the pathogenic potential of this organism. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/13500872-142-8-2161
