Male mice (NMRI strain) of 3 and 5 g were inoculated i. p. with 8 x 10 and 9 x 10 metatrypomastigotes/g harvested from a 12-day-old LIT culture of Try­ panosoma rangeli of the "Dog-82" strain. At regular intervals after inoculation, the animals were sacrificed and portions of heart, liver, spleen, lung, thigh, kidney, stomach, intestine, brain, sternum, and vertebral column were embedded in par...

A study was conducted to determine the prevalence of natural infections by trypanosome species in squirrel monkeys: Saimiri sciureus (Linnaeus) and Saimiri ustus (Geoffroy) caught respectively near 2 hydroelectric plants: Balbina, in the State of Amazonas, and Samuel, in the State of Rondônia, Brazil. A total of 165 squirrel monkeys were examined by thick and thin blood smears (BS), haemocultur...

Trypanosoma comprises flagellates able to infect several mammalian species and is transmitted by several groups of invertebrates. The order Chiroptera can be infected by the subgenera Herpetosoma, Schizotrypanum, Megatrypanum and Trypanozoon. In this study, we described the diversity of bat trypanosomes and inferred phylogenetic relationships among the trypanosomes from bats caught in Tapajós-A...

Wild rabbits (Oryctolagus cuniculus) in Australia are the descendents of 24 animals from England released in 1859. We surveyed rabbits and rabbit fleas (Spilopsyllus cuniculi) in Australia for the presence of trypanosomes using parasitological and PCR-based methods. Trypanosomes were detected in blood from the European rabbits by microscopy, and PCR using trypanosome-specific small subunit ribo...

TARGETT, G. A. T., AND VIENS, P. 1975. Ablastin: Control of Trypanosoma musculi infections in mice. Experimental Parasitology 38, 309316. Trypanosoma musculi infections in CBA mice consist of a phase of increasing parasitemia during which dividing forms of the parasite are present in the blood, followed by a period when only nondividing trypomastigotes are seen. A second crisis terminates the b...
