<P> Trypanosoma cruzi is a species of parasitic euglenoids . Amongst the protozoa , the trypanosomes characteristically bore tissue in another organism and feed on blood ( primarily ) and also lymph . This behaviour causes disease or the likelihood of disease that varies with the organism : for example , trypanosomiasis in humans ( Chagas disease in South America ) , dourine and surra in horses , and a brucellosis - like disease in cattle . Parasites need a host body and the haematophagous insect triatomine ( descriptions `` assassin bug '' , `` cone - nose bug '' , and `` kissing bug '' ) is the major vector in accord with a mechanism of infection . The triatomine likes the nests of vertebrate animals for shelter , where it bites and sucks blood for food . Individual triatomines infected with protozoa from other contact with animals transmit trypanosomes when the triatomine deposits its faeces on the host 's skin surface and then bites . Penetration of the infected faeces is further facilitated by the scratching of the bite area by the human or animal host . </P>
