Xenodiagnosis

from Wikipedia, the free encyclopedia

The xenodiagnosis ( Greek ξενοδιάγνωση, xenodiágnosi , literally "the differentiation" in the sense of "differentiation through something foreign") is a detection method for suspected American trypanosomiasis ( Chagas disease ) (not: tropical sleeping sickness = African trypanosomiasis , Fly Glossina morsitans is transmitted).

In xenodiagnosis, healthy, uninfected predatory bugs are placed on to suck (small jars on the skin) and the trypanosomes are then detected in the faeces of the predatory bugs. This is a fast and, above all, inexpensive diagnostic detection method, but nowadays detection is mostly carried out via antibody determination in serum (IF, EIA, HA).
