Dimiconin, a novel coagulation inhibitor from the kissing bug, Triatoma dimidiata, a vector of Chagas disease.
Sequence analysis of a Triatoma dimidiata salivary gland cDNA library resulted in the identification of two transcripts (Td60 and Td101) homologous to triabin, an inhibitor of thrombin in Triatoma pallidipennis saliva. In the present study, a recombinant protein of Td60, designated dimiconin, was expressed in Escherichia coli and its activity was characterized. The resulting protein inhibited t...
متن کاملChagas disease parasite induces behavioural changes in the kissing bug Mepraia spinolai.
Parasites have been shown to manipulate the feeding behaviour of their invertebrate vectors, which results in an increased probability of transmission to definitive hosts. Most evidence for this hypothesis comes from protozoan species with salivary transmission but evidence for stercorarian parasite transmission is lacking. We present experimental evidence that infection of the kissing bug Mepr...
متن کاملCloning and Expression of Thermus Aquaticus DNA Polymerase Gene, Using a Thermo-Inducible Expression Vector
DNA polymerase gene from Thermus aquaticus strain YT1 was amplified using VENTTM DNA po-lymerase and cloned under the control of X.PR promoter and expression was induced by a shift in tern perature. The culture was then sonicated, and after centrifugation the lysate was treated with polyethyleneimine followed by a salting-out step. Finally the protein was precipitated with ammonium sulfate and...
متن کاملThe 1899 United States Kissing Bug Epidemic
Carlos Chagas is credited with the discovery of Chagas disease because of his 1909 published findings of the Trypanosoma cruzi parasite isolated in the blood of a Brazilian patient [1]. Following his discovery, reports of Chagas disease from across Latin America were published, classifying these countries as endemic with continual transmission occurring [2]. The United States has long been cons...
متن کاملA country bug in the city: urban infestation by the Chagas disease vector Triatoma infestans in Arequipa, Peru
BACKGROUND Interruption of vector-borne transmission of Trypanosoma cruzi remains an unrealized objective in many Latin American countries. The task of vector control is complicated by the emergence of vector insects in urban areas. METHODS Utilizing data from a large-scale vector control program in Arequipa, Peru, we explored the spatial patterns of infestation by Triatoma infestans in an ur...
