متن کاملTrypanosoma (Herpetosoma) rangeli Tejera, 1920: an updated review.
Trypanosoma rangeli, a parasite generally considered non-pathogenic for man, is the second species of human trypanosome to be reported from the New World. The geographical distribution of T. rangeli often overlaps with that of T. cruzi, the same vertebrate and invertebrate hosts being infected. Their differentiation thus becomes of real, practical importance, particularly as they share approxim...
متن کاملTrypanosoma (Herpetosoma) rangeli Tejera, 1920: preliminary report on histopathology in experimentally infected mice.
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...
متن کاملTrypanosoma (Herpetosoma) rangeli Tejera, 1920: influence of host weight, size of inoculum, and route of infection upon experimental parasitemia.
To study the influence o f host age, inoculum size, and route o f infection on Trypanosoma (Herpetosoma) rangeli, 12 lots o f 6.0 g albino mice (NMRI strain) were infected up. with from 25x101 to 25xl(fi trypomastigotes/gram body weight harvested from LIT medium. The lower inocula produced low but persistent parasitemias, while the higher inocula produced high levels o f parasitemia that fell q...
متن کاملFirst report on the occurrence of Trypanosoma rangeli Tejera, 1920 in the state of Ceará, Brazil, in naturally infected triatomine Rhodnius nasutus Stål, 1859 (Hemiptera, Reduviidae, Triatominae).
The aim of this work was to identify and report the occurrence of Trypanosoma rangeli and Trypanosoma cruzi in naturally infected Rhodnius nasutus (Hemiptera, Reduviidae, Triatominae) in the state of Ceará, Brazil. Triatomines feces, salivary glands, and hemolymph were collected for fresh examination, and specific detection of T. rangeli and T. cruzi DNA by polymerase chain reaction was carried...
