Role 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 کاملStudies 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 کاملBerenil (diminazene aceturate)-resistant Trypanosoma congolense in cattle under natural tsetse challenge at Kibaha, Tanzania.
Twenty-nine cattle, naturally infected with Trypanosoma congolense Kibaha, were subjected to chemotherapy with diminazene aceturate (Berenil, Hoechst) at 3.5 to 14.0 mg/kg. Fourteen animals recovered while six were refractory to treatment at 7.0 to 14.0 mg/kg. Further treatment of the Berenil-resistant isolates with isometamidium chloride (Samorin, May and Baker) at 1.0 mg/kg, effected cure. Co...

متن کاملResistance of cattle to tsetse-transmitted challenge with Trypanosoma brucei or Trypanosoma congolense after spontaneous recovery from syringe-passaged infections.
Groups of cattle were inoculated intravenously with cloned populations of bloodstream forms of Trypanosoma brucei or Trypanosoma congolense. All five steers infected with T. brucei ILTat 2.1 and six of the eight steers infected with T. congolense IL 13-E14 became aparasitemic within 16 and 32 weeks postinfection, respectively. Examination of sera from animals infected with T. brucei by indirect...
