Figure Lengend Snippet: Effect of VP4 of human and simian origin on rotavirus replication in vitro and shedding in vivo . ( a ) Titer of recombinant VP4 mono-reassortments on CDC-9 P11 background in MA104 cells. N = 6. One-way ANOVA was performed comparing mean titers of recombinant strains to rCDC-9 P11. ( b ) Infection of 5-day-old neonatal rats with 1 × 10 7 FFU of the indicated recombinant rotavirus strains. Bodyweight was monitored for 14 days post infection. N = 10 (days 0–5) and N = 5 (days 6–14). ( c ) Shedding in neonatal rats after infection with 1 × 10 7 FFU of the indicated recombinant rotavirus strains. Shedding was measured in rectal swabs by Premier Rotaclone EIA. Two-way ANOVA with multiple test comparison was performed to compare mean shedding after infection with recombinant strains to mean shedding after rCDC-9 P11 infection. ns, not significant ( P ≥ 0.05); * P < 0.05. Shown are mean and SEM for all experiments.
Article Snippet: African green monkey kidney epithelial cell line MA104 (ATCC CRL-2378.1) was passaged in 199 medium (Sigma Aldrich, St. Louis, MO, USA) supplemented with 10% fetal bovine serum (FBS, one shot, Gibco), 100 IU penicillin/mL, 100 μg/mL streptomycin, and 0.292 mg/mL L-glutamine as previously described ( ).
