Infectivity of wild-type rubella virus in fibrochondrocyte cells
This study describes the rapid growth of the rubella virus in samples of a primary fibrochondrocyte cell culture with the development of a cytopathic effect (CPE), in response to infection by the rubella virus. The cells were isolated from the meniscus joint of a rabbit after enzymatic extraction and incubated at 37°C with a Dulbecco's modified Eagle's medium (DMEM), supplemented with 10% fetal calf serum. A total of six clinical samples from urine, blood and cerebrospinal fluid were inoculated in the fibrochondrocyte and the cell lines of the African green monkey kidney - ATCC CCL-81 (Vero). The fibrochondrocyte cell showed CPE after 24 hours and virus growth was confirmed by immunohistochemistry and Nested PCR. The cells inoculated with samples were examined by phase contrast microscopy and showed characteristic rounding, along with bipolar and multipolar cells. The infection curve increased during the five days of observation, showing that the titers in fibrochondrocyte cells were then higher than those observed in Vero cell lines.
