Growth kinetics and CPE of LACV strains. A. Growth kinetics of LACV/human/1960, LACV/human/1978, and LACV/mosquito/1978 in Vero cells or C6/36 cells infected at an MOI of 0.01. B. Photographs of mock or LACV/human/1960 infected Vero cell monolayers from panel "A". Cell rounding and detachment from the flask can be seen on days 2–4 post-infection in infected monolayers.
