The three C. fasciculata strains (Culex, Wallace isolate: Culex, Nöller isolate: Anopheles strain) and C. oncopelti are immunologically similar according to agglutination tests. Crithidia sp. from Euryophthalmus and C. luciliae are distinct from each other and from C. oncopelti. The two Leptomonas species are distinct from each other and are not closely related immunologically to Crithidia species. The trypanosomatids tested here are not separable into groups according to original host (hemiptera or diptera). %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-48-1-45
