Isolation of Chlamydia trachomatis in Untreated MMC-E mouse epithelial cells

The susceptibility of the epithelial mouse embryo cell line MMC-E to infection with Chlamydia trachomatis was studied by using chlamydiae from both laboratory strain L2 and clinical specimens. MMC-E cells were sensitive to infection with C. trachomatis without any pre- or posttreatments, and their susceptibility for isolation was comparable to that of the conventionally used irradiated McCoy cells.
