Genomic analysis of Theileria sergenti stocks in Japan with DNA probes.
Restriction fragment length polymorphisms of Theileria sergenti DNA from 18 different infections of cattle in 14 locations in Japan were analyzed by Southern blotting using T. sergenti genomic DNA fragments as probes. Probe pTs 2 hybridized with four fragments in BamHI digested piroplasm DNA, at 8.0, 7.3, 6.0 and 3.4 kb. Probe pTs 11-D1 hybridized with multiple fragments. With each probe, polymorphisms were observed among stocks from different locations. However, there was no correlation between the patterns of hybridization bands and the locations where parasites were collected. Analysis of the hybridization patterns of stocks obtained from individual cattle in the same grazing areas showed an almost identical pattern.
