2. OBJECTIVEHorizontal transmissibility of the foot-and-mouth disease virus (FMDV) O/JPN/2010, which was isolated in the 2010 epidemic in Japan, has been analysed among the same species of animals such as cows, goats and pigs in our previous studies.The O/JPN/2010 transmitted horizontally to the same species of all contact animals.In this study, horizontal transmissibility of the O/JPN/2010 among the different species of animals was analyzed in order to elucidate difference of transmission situations of FMDV among the same and different species of animals.
3. RESULTS
4. DISCUSSIONHorizontal transmission of the O/JPN/2010 occurred completely among the same species of animals; however, the transmission did not occur completely among the different species of animals in this study, especially from the goats to the cows and pigs.Appearance of vesicular lesions may be involved in horizontal transmissibility of the O/JPN/2010 in animals because the lesions in the inoculated cows and pigs were more apparent than those in the inoculated goats.However, goat-to-goat transmission occurred completely in our previous study; therefore, any other factors may influence horizontal transmissibility of FMDV among the different species of animals.
