Bacteriol. 91:1986-1991. 1966.-The infectious synthetic cycle of Yaba poxvirus by BSC-1 cells at 35 C is described and discussed together with related observations obtained by immunofluorescence and electron microscopy. After adsorption of virus at 25 C, at least 6 hr of incubation at 35 C was required before viral eclipse was demonstrable. Infectious progeny appeared after an additional 48 hr of incubation at 35 C. Newly synthesized virus particles were seen at 68 hr but not at 44 hr by electron microscopy. Maximal maturation occurred between 100 and 120 hr. Maximal yields were obtained from the 5th through the 8th day. The differences in kinetics between Yaba and vaccinia poxviruses, as described for the latter in the literature, are discussed. Possible factors accounting for these differences are enumerated.
