Trypanosoma vivax – out of Africa

Trends in Parasitology, 2001
Trypanosoma vivax is a blood parasite of ruminants that was introduced into Latin America in cattle imported from Africa, possibly in the late 19th century. The parasite has now spread to ten of the 13 countries of the South American continent, often resulting in a severe wasting disease and death.

The fatty acids of trypanosoma vivax

International Journal of Biochemistry, 1983
A study was carried out to determine the lipid composition of the blood-stream form of the African trypanosome. Trypanosoma vivax. Data from thin layer chromatography showed that the major polar lipids were lysophosphatidylcholine, sphingomyelin, phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine and diphosphatidylglycerol.

Morphological changes of Trypanosoma vivax in mice

Veterinary Parasitology, 1986
Morphological changes were observed in the blood forms of Trypanosoma vivax strain Y486 in mice on Days 12-13 of infection, following the peak parasitaemia. During this period elongate trypomastigotes, 25-40 micron long, were observed, most showing an anterior movement of the kinetoplast towards the nucleus and some having a blunt posterior end.

The phosphoglucose isomerases of the bloodstream forms of Trypanosoma brucei and Trypanosoma vivax

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1978
1. The phosphoglucose isomerases (PGI's) of the bloodstream forms of Trypanosoma brucei and T. vivax have been purified some 150-fold, using cellulose ion-exchange chromatography, gel filtration and isoelectric focussing. 2. The two trypanosome enzymes showed many similarities in kinetic properties, but differed from each other somewhat in thermal ...

Observations on the metabolism of Trypanosoma vivax

Experimental Parasitology, 1956
Abstract 1. 1. The metabolism of two strains of T. vivax was studied, one a strain adapted to rats and no longer capable of developing in the tsetse, the other a “natural” strain maintained in sheep by cyclical transmission through Glossina palpalis . 2. 2.

Infectivity and virulence in a serodeme of Trypanosoma vivax

Comparative Immunology, Microbiology and Infectious Diseases, 1988
The course of infection by a mouse-adapted Trypanosoma vivax was studied. Serological variants were isolated from sheep and their infectivity and virulence were studied in mice and sheep. Isolates obtained in the early stage of the infection were highly virulent while isolates obtained at the terminal stage of the infection were found to be extremely ...

The pathology and pathogenesis of Trypanosoma vivax infection in the goat

Research in Veterinary Science, 1976
Acute and chronic forms of disease can be distinguished in Trypanosoma vivax infection in the goat. The main difference between the acute and chronic form seems to be the presence of microthrombi in the acute stage of infection; these consist of platelets, trypanosomes, monocytoid cells and some fibrin. This thrombus formation seems directly related to

Trypanosoma vivax in Colombia: Interpretation of field results

Tropical Animal Health and Production, 1982
The use of the indirect fluorescent antibody test and complementary blood smear examinations in Colombia has shown that Trypanosoma vivax infections of cattle may be considered to be distributed throughout the tropical and subtropical areas of the country.

Trypanosoma vivax displays a clonal population structure

International Journal for Parasitology, 2009
African animal trypanosomiasis, or Nagana, is a debilitating and economically costly disease with a major impact on animal health in sub-Saharan Africa. Trypanosoma vivax, one of the principal trypanosome species responsible for the disease, infects a wide host range including cattle, goats, horses and donkeys and is transmitted both cyclically by ...
