| | | Telok Forest virus is related to Bakau and Ketapang viruses of the Bakau group and all three are related to Nola virus [3] . Hyperimmune mouse sera for the following viruses failed to reduce Telok Forest plaques in Vero cells: BAK, BAT, BC, BEB, BHA, BWA, CI, CHP, CGL, CHIK, DEN-1, DEN-2, DEN-3, DEN-4, EEE, EMC, GAN, GET, herpesvirus, ILH, JUG, JE, KET, KTR, LGT, LJN, MAY, MIN, MVE, NTA, ONN, RR, SFN, SFS, SAT, SEL, SF, SIN, TR, TMU, UMB, WEE, WN, WSL, YF, AND ZIKA. | | The Yale Arbovirus Research Unit reported that Telok Forest was negative by CF with 14 grouping fluids and did not react with 216 individual antigens, including LCM, NDV, rabies, reovirus, and vaccinia, except for its homologous [1] . | | Subsequently, we found Telok Forest to be indistinguishable by CF from the ungrouped Tanjong Rabok virus (P8-1542 strain), which was isolated from the blood of a monkey captured in a nearby forest in Malaysia. The two viruses were distinguished by both HI and PRNT, showing no cross reaction. | | | | | Antigen |
