a) Viral neutralizing antibody (VNA) titers against rabies virus (RABV) were determined by fluorescent antibody virus neutralization (FAVN) test. The protective VNA titers more than 0.5 IU/ml were indicated as seropositive against RABV. b) The VNA titers (0.29 and 0.06 IU/ml) of 2 dogs were lower than protective level (0.5 IU/ml) among 4 military dogs born in 2014.
