Studies on Trypanosoma (nannomonas) congolense. I. On the morphological appearance of the parasite in the mouse.
The pleomorphism of bloodstream Trypanosoma (Nannomonas) congolense was studied during the course of the first parasitaemic wave in mice using cloned and uncloned derivatives of three recent field isolates. The different morphological types were identified using the criteria described by Godfrey (1960). It was found that at any point of parasitaemia there were several morphological types of the...
متن کاملAtypical hyperpachymorph Trypanosoma (Nannomonas) congolense forest-type in a dog returning from Senegal
Trypanosoma congolense forest-type was identified by PCR in France, in a dog returning from Senegal. This paper describes the morphological features of the parasite on Giemsa-stained smears. Slender forms and "latent bodies" represent 30.4% and 20.4%, respectively. Some rosettes have been observed (0.8%). The predominant form (48.4%) is stumpy, close to "montgomeryi-form", but it is unusually b...
متن کاملTrypanosoma (Nannomonas) congolense: properties of hexokinase and phosphofructokinase from cultured procyclic trypomastigotes and bloodstream forms.
The distribution and kinetics of two key glycolytic enzymes hexokinase (HK) and phosphofructokinase (PFK) were studied in animal-infective bloodstream forms (haematozoic trypomastigotes) and uninfective procyclic forms (insect trypomastigotes) of Trypanosoma congolense. The results show that in both forms of T. congolense HK and PFK are particulate and are probably localized in a membrane-delim...
متن کاملRole of the chancre in induction of immunity to tsetse-transmitted Trypanosoma (Nannomonas) congolense in goats.
Local skin reactions (chancres) developed in goats at the sites of deposition, by tsetse flies, of metacyclics of Trypanosoma congolense. The chancres developed much faster and were more pronounced when ten infected tsetse were allowed to feed on a spot as compared to only one fly per spot. The initial host cellular reaction in the chancre was predominantly polymorphonuclear, followed at the pe...
متن کاملDetection and identification of trypanosomes by polymerase chain reaction in wild tsetse flies in Cameroon.
The prevalence of various species and subgroups of trypanosomes in infected flies from three sleeping sickness foci in Cameroon was determined by the use of polymerase chain reaction (PCR). The predominant tsetse species found were Glossina palpalis palpalis. Microscopical examination of 943 non-teneral tsetse flies revealed an average infection rate of 10.4%. A total of 90 flies were analyzed ...
