The aim of this study was to investigate the behavioral assessment and activities of important enzymes involved in the phosphoryl transfer network in rat brains that were experimentally infected with Trypanosoma evansi. Behavioral assessment (cognitive performance), pro-inflammatory cytokines in serum and activities of adenylate kinase (AK), pyruvate kinase(More)
The efficacy of immersion anaesthesia with tricaine methanesulphonate (MS222) or propofol on albino and grey silver catfish Rhamdia quelen was assessed through induction and recovery times and observation of mortality. Besides reporting a novel, efficient and practical use of propofol as an immersion anaesthetic, the study shows that it is essential to(More)
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,(More)
The aim of this study was to evaluate the relationship between testicular lesions and hormone levels in rats experimentally infected with Trypanosoma evansi. For that, the measurement of reproductive hormones, histopathology and biomarkers of cellular injury were carried out in twenty-four animals, which were divided into two groups with 12 animals each.(More)
This study aimed at evaluating hemogram and erythropoietic changes in cats experimentally infected with Trypanosoma evansi. Thirteen adult female non-breeding Felix catus were separated into two groups: seven animals were infected with 10(8) trypomastigotes each, and six animals were used as negative controls. Animals were kept in air-conditioned rooms and(More)
The aim of this study was to evaluate the purine levels of lambs experimentally infected with Haemonchus contortus. A total of 12 healthy lambs were divided into two groups, composed of 6 animals each: Group A represented the healthy animals (uninfected), while in Group B the animals were infected with 15 000 larvae of H. contortus. Blood was drawn on days(More)
The purpose of this study is to report the occurrence of new serovars of Leptospira interrogans in cavy in Brazil. Blood without anticoagulant was collected from five Cavia aperea to obtain serum for further testing with serum agglutination using eight serovars of L. interrogans. It was observed that four animals had titers for L. butembo, L. bratislava,(More)
This study aimed to evaluate the susceptibility of Brazilian isolates of Trypanosoma evansi to suramin sodium. For this purpose, three isolates of T. evansi (LPV-2005, LPV-2009 and LPV-2010) and seventy mice were used, with the animals divided in 10 groups (A, B, C, D, E, F, G, H, I and J) with seven animals each group. Mice of groups A, B, and C were(More)
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. evansi isolates to therapy using(More)
The aim of this study was to compare the efficacy of the therapy with human plasma of different blood types and Rh factors in rats infected with Trypanosma evansi. Sixty rats were divided into ten groups of six animals (A-J). Animals from group A (negative control) were not infected and animals from group B (positive control) were inoculated with T. evansi(More)
