Geographic distribution of isolates of the two taxa of C. immitis, identified using restriction enzyme analysis of two polymorphisms in serine proteinase distinguishing the two taxa: Kern (14 isolates; 1993–94), Santa Barbara (3), San Diego (15, including 4 isolates from soil; 1975–94 and 1969, respectively), and Ventura (4) Counties, CA; Tucson, Arizona (25; 1979–90); San Antonio, TX (17; 1992–93); and Monterrey, Mexico (6). Solid circles, Californian genotype; open circles: non-Californian genotype. Six isolates from Argentina and one isolate from Washington State are not shown.
