The growth of bovine respiratory syncytial virus (BRSV) was evaluated in six different cell lines. Chicken embryo related cells (CER), a chicken embryo fibroblast/baby hamster kidney hybrid and bovine CRIB cells (a bovine viral diarrhea virus-resistant clone of MDBK cells) showed to be the most appropriate for virus multiplication. Both cells provided infectious virus titres of up to 105.5 50% tissue culture infective doses per 100 _l (TCID50/100_l). One-step growth curves revealed no significant differences in the growth of BRSV in these two cell lines. Furthermore, they proved to be susceptible to infection with three different BRSV strains. It was concluded that both CER and CRIB cells may be used for laboratory multiplication of BRSV with optimal results.
