Mechanical Transmission in Trypanosomiasis

Urban Transmission of Human African Trypanosomiasis, Gabon

at symptom onset, but results for patient serum samples cultured under the same conditions as the homogenized parasites remained negative. Signifi cant titers of IgG against B. quintana and B. henselae or IgG seroconversion in paired serum samples were observed for all patients except the grandfather (Table). Oral clarithromycin and doxycycline were administered to the children and adults, resp...

Modeling household transmission of American trypanosomiasis.

American trypanosomiasis, or Chagas disease, caused by the protozoan parasite Trypanosoma cruzi and transmitted by blood-feeding triatomine bugs, is a chronic, frequently fatal infection that is common in Latin America. Neither adequate drugs nor a vaccine is available. A mathematical model calibrated to detailed household data from three villages in northwest Argentina shows that householders ...

Human African Trypanosomiasis Transmission, Kinshasa, Democratic Republic of Congo

To investigate the epidemiology of human African trypanosomiasis (sleeping sickness) in Kinshasa, Democratic Republic of Congo, 2 entomologic surveys were conducted in 2005. Trypanosoma brucei gambiense and human-blood meals were found in tsetse fly midguts, which suggested active disease transmission. Vector control should be used to improve human African trypanosomiasis control efforts.

Trypanosomiasis

The blood-films which I have shown1 were taken from a case of Dr. Skerritt's which was under my care for a period of two months during the past summer. The clinical history of the case will be found in the British Medical Journal, May 30th, 1903. The patient died on November 26th, and details of the postmortem examination will be published shortly. Trypanosomes belong to the order of Protozoa. ...
