Transmission of the SW/3/06 virus in guinea pigs. Three guinea pigs were inoculated i.n. with 106 EID50 of the SW/3/06 virus and, 24 h post-inoculation, three contact guinea pigs were placed in each cage. Nasal washes were collected every two days from all animals beginning 2 dpi for detection of virus shedding. Numbers of guinea pigs shedding virus are shown in each point and square. The lower virus limit detection was 100.75 EID50/mL.
