The count is proportional to the bacterial concentration in the suspension and also to the average speed of the bacteria. A slight increase in the viscosity of the suspending medium above that of a buffer solution has the effect of increasing motility; further increase in viscosity decreases it., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-22-2-528
