Description:Under a very high magnification of 35,000X, this scanning electron microscopic (SEM) image revealed a cluster of Gram-positive, beta-hemolytic Group C Streptococcus sp. bacteria.
“The genus Streptococcus is comprised of microaerophilic cocci (round), which are not motile and occur in chains or pairs. The genus is defined by a combination of antigenic, hemolytic, and physiological characteristics into Groups A, B, C, D, F, and G. Groups A and D can be transmitted to humans via food.”
