| | | Silverwater virus diluted to contain 30 to 100 intracerebral newborn mouse LD50 was not neutralized by antisera to the following viruses: EEE, WEE, SLE, POW, CTF, BUN. | | No complement-fixation reactions with Silverwater antigen in the presence of antisera to the above-mentioned viruses, except CTF which was not tested. Antigens of POW, BUN, SLE, and EEE did not fix complement in the presence of SIL antiserum. | | The Yale Arbovirus Research Unit showed that Silverwater is related to Kaisodi and Lanjan by cross CF tests and thus is a member of the Kaisodi group [4] . | | |
