PREVALENCE AND DISTRIBUTION OF ARBOVIRUSES.
Abstract
The report presents results of studies on indigenous arboviruses, as follows: (1) Prevalence and distribution of antibody to West Nile (WN) and Sindbis viruses in four villages in the South of Israel. The results indicate that antibody to West Nile virus is quite prevalent in these rural areas, ranging between 33 and 50 percent as contrasted to its scarcity in the city of Beer Sheba. Antibody to Sindbis virus is significantly lower and there is a positive correlation between the presence and absence of antibody to these two viruses. (2) Tests of antibody to WN and Sindbis viruses in locally produced gamma globulin. The antibody titer to WN virus in four batches of locally produced gamma globulin was found to be in the range of 1:40 to 1:80; no, or a very low, antibody titer to Sindbis virus was found in these batches. (3) The isolation of a small-plaque variant of WN virus with lowered mouse virulence. This variant was isolated from a chronic infection of WN virus in LLC-MK2 cells (LLCWN carrier cultures).
