Abstract

Fifty plaque samples were collected from teeth. Forty five samples were considered to be positive bacterial isolates about (104 bacteria/ml) using selective Ms-agar (Mitis-Salivarius agar) medium. Thirty isolates were considered to be related to the genus Streptococcus and specially to the mutans streptococci of various group; S. sobrinus (serotype D, G), S. mutans (serotype C, F), S. cricetus (serotype A) and S. rattus (serotype B) with percentages of (39.29%), (30.30%), (18.18%) and (3.03%), respectively depending on biochemical and Lancefield grouping identification systems.
