    (egg, larva, nymph and adult). The females had 2 nymphal stages, but the males had only one. Their morphologies were different. K. mutans could survive in vitro for 4-9 days at 4-25°C. The maximum survival times of K. mutans in vitro were 120 h at pH 4,132 h at pH 5, 96 h at pH 7 and 96 h at pH 8, respectively. Histopathological changes showed that K. mutans parasitized the corneous layer. In acute infectionsinfectionsSubject Category: Diseases, Disorders, and Symptoms
