Trypanocidal activity of human plasma on Trypanosoma evansi in mice.

This study aimed to test an alternative protocol with human plasma to control Trypanosoma evansi infection in mice. Plasma from an apparently 27-year-old healthy male, blood type A+, was used in the study. A concentration of 100 mg.

Susceptibility of mice to Trypanosoma evansi treated with human plasma containing different concentrations of apolipoprotein L-1.

The aim of this study was to test the susceptibility of mice to Trypanosoma evansi treated with human plasma containing different concentrations of apolipoprotein L-1 (APOL1). For this experiment, a strain of T. evansi and human plasma (plasmas 1, 2, and 3) from 3 adult males clinically healthy were used.

Diminazene aceturate associated with sodium selenite and vitamin E in the treatment of Trypanosoma evansi infection in rats.

The aim of this study was to evaluate the utilization of a standard treatment with diminazene aceturate against the infection caused by Trypanosoma evansi, associated to sodium selenite and vitamin E. In vitro tests showed trypanocidal effect related to the treatment with diminazene aceturate and sodium selenite, but vitamin E had no harmful effect on the trypanosomes. In vivo experiments utilized a total of 72 adult outbreed females rats, separated into 9 groups (A, B, C, D, E, F, G, H and I), 8 animals each.

Biochemical changes in cats infected with Trypanosoma evansi.

This study aimed at evaluating biochemical changes of cats (Felis catus) experimentally infected with Trypanosoma evansi. Seven animals were infected with 10(8) blood trypomastigotes per animal and six were used as controls. Blood smears were performed daily for 56 days and the hepatic, renal and muscular parameters in blood serum were evaluated at days 0, 7, 21, 35 and 49.

Susceptibility of Trypanosoma evansi to human blood and plasma in infected mice.

Around 1900 Laveran and Mesnil discovered that African trypanosomes do not survive in the blood of some primates and humans. The nature of the trypanolytic factor present in these sera has been the focus of a long-standing debate between different groups. The aim of this study was to investigate the susceptibility of T.

Duddingtonia flagrans: centrifugal flotation technique with magnesium sulphate for the quantification and qualification of chlamydospores in sheep faeces.

Duddingtonia flagrans is a nematode-trapping fungus responsible for attacking larval stages of helminths in pasture, which has potential as a biological control method. The aim of this study was to test the magnesium sulphate centrifugal flotation technique for the quantification of D. flagrans chlamydospores in sheep faeces and to verify their morphological viability.

[Infestation by Ornithocoris sp. at dwellings in the Municipality of Santa Maria, Rio Grande do Sul State, Brazil].

Ornithocoris is a Hemiptera of the family Cimicidae that parasitizes wild and domestic birds. We considered opportune to report two isolate cases of parasitism by Ornithocoris sp. at dwellings in the municipality of Santa Maria, RS.

[Accidental myiasis by Ornidia obesa in humans].

Dipterous of the genus Ornidia are pollinator bugs, but immature stages can be found in organic matter in decomposition. This article refers to a found of larvae of Ornidia obesa in humans feces. An eight years old child was treated in a medical clinic due to the presence of two larvae and one pupae in the feces, hyperthermia, intestinal obstruction and strong abdominal pain.
