Sensitivity of seven different types of cell cultures to three serotypes of foot-and-mouth disease virus

Abstract

The ability of bovine tongue origin foot-and-mouth disease virus serotypes A, O and C to replicate in seven different types of cell cultures was studied. Primary and secondary calf thyroid cells were equivalent in susceptibility to bovine kidney cell cultures passaged up to five times. Calf thyroid cells lost their susceptibility after two passages. Cryopreserved bovine kidney cell cultures passaged three and four times were equivalent in susceptibility to sensitive calf thyroid and bovine kidney cells. Susceptibility to foot-and-mouth disease virus serotype C was most variable among the cells tested. Lamb testicle and porcine kidney cells were susceptible to foot-and-mouth disease virus while goat and calf testicle and calf lung cells were refractory.
