Comparative susceptibility of some avian and mammalian lymphoblastoid cell lines to chicken anemia virus.

Although MSB1 is the most-commonly used lymphoblastoid cell line for isolation of chicken anemia virus (CAV), some researchers have reported a few biological drawbacks. None of them were supported by the results of the present study. Another four avian (HP1, HP2, BK3 and CU10) and two mammalian (BTL-26 and KO-1) cell lines were investigated for susceptibility to the TK-5803 and AH-9409 strains. Both strains caused CPE on BK3 like MSB1. The mean number of positive cells for each strain in MSB1 and BK3 were not significantly different. The majority of the HP2, CU10 and HP1 cells showed no CPE. The virus titers of both strains were higher in MSB1 and BK3 (10(6.5-7.5) TCID(50)/0.1 ml) than in HP2, CU10 and HP1 (10(3.5-4.5) TCID(50)/0.1 ml). BTL-26 and KO-1 were resistant to CAV. BK3 could be used for isolation of CAV.
