Consulta: subjectFacets:"Trypanosomiasis" Registros recuperados: 9 Data/hora: 08/06/2017 20:48:21 Valores de transaminasas en cabras criollas infectadas con Trypanosoma vivax. Provedor de dados: 119 Autores: ESPINOZA, E.; PRIMERA, G. La presente comunicación reporta los valores de las enzimas transaminasas, Aspartatoaminotransferasa (AST) y Alaninaamino-transferasa (ALT) encontrados en sueros de cabras infectadas con la cepa de Trypanosoma vivax Stock (TvIIV) y sus controles. Las determinaciones se realizaron durante un lapso experimental de diez semanas, divididos en dos períodos iguales (pre y post-infección) por intermedio de un método colorimétrico, utilizando kits comerciales. Los datos fueron analizados mediante la prueba t Student's. En el caso de la AST, la comparación de las medias parciales de ambos grupos infectado y control, no indicó diferencias estadísticas. Con respecto a la ALT, la contrastación de las medias parciales de pre y post-infección del grupo de cabras...

Five adult donkeys were experimentally infected with Brazilian strain of Trypanosoma evansi originally isolated from a naturally infected dog to study the hematological biochemical and histopathological alterations during the evolution of the disease. The course of the experimental infection was followed up to 145 days. Hematological analyses of the infected donkeys revealed a marked decline in hemoglobin, packed-cell volume, and erythrocyte count. Anemia was observed after successive peaks of parasitemia. Biochemical analyses showed increased levels of icterus index, serum globulins and decreased serum albumin and glucose values. All infected donkeys revealed enlargement of spleen and its white pulp, enlargement of mediastinal lymph nodes and lungs...

Abstract During the course of evolution, multicellular organisms have been orchestrated with an efficient and versatile immune system to counteract diverse group of pathogenic organisms. Pathogen recognition is considered as the most critical step behind eliciting adequate immune response during an infection. Hitherto Toll-like receptors (TLRs), especially the surface ones viz. TLR2 and TLR4 have gained immense importance due to their extreme ability of identifying distinct molecular patterns from invading pathogens. These pattern recognition receptors (PRRs) not only act as innate sensor but also shape and bridge innate and adaptive immune responses. In addition, they also play a pivotal role in regulating the balance between Th1 and Th2 type of response...

Four cases of serious cardiac attacks by autochthonous Trypanosoma cruzi infection from the Brazilian Amazon are reported; three of them occurred in micro-epidemic episodes. The manifestations included sudden fever, myalgia, dyspnea and signs of heart failure. Diagnosis was confirmed by specific exams, especially QBC (Quantitative Buffy Coat) and natural xenodiagnosis. Despite treatment with benznidazol, three patients died with serious myocarditis, renal failure and cardiac tamponade. The authors call attention to the emergence of this disease and reveal a previously unknown pathogenicity of T. cruzi strains in this area, added to a non-usual transmission form.

ABSTRACT: Two outbreaks of trypanosomiasis by Trypanosoma evansi in horses in the municipality of Chaves, Marajó Island, Pará State, Brazil are reported. The first outbreak occurred in April 2011 in a farm with 147 horses; of these, 47 (31.97%) got sick, and 40 (27.21%) died. The second outbreak occurred in May 2012 and involved nine properties. Of a total of 679 horses, 209 (30.07%) got sick, and 183 (26.97%) died. The main clinical signs observed in these horses were weight loss, abdominal edema, toe dragging, and pelvic muscle atrophy. Necropsy was performed in two horses, one from each outbreak. Macroscopic alterations were not seen in the horse from the first outbreak; however, the horse from the second outbreak exhibited emaciation, pallor and...

Ano: 1999 URL: http://ir.obihiro.ac.jp/dspace/handle/10322/317 Effect of aflatoxin B1 on the therapeutic efficacy of suramin in Trypanosoma brucei rhodesiense-infected mice Provedor de dados: 19 Autores: Kibugu, J.K.; Mdachi, R.E.; Kagira, J.M.; Muchiri, M.W.; Makumi, J.N.; Ngeranwa, J.J.N.; Auma, J. E.; Ngae, G.N. Through immuno-suppression, aflatoxins could affect drug and vaccine efficacy. Such effects have not been evaluated in treatment of many diseases including trypanosomiasis. We assessed the effect of aflatoxin B1 on the efficacy of suramin, the drug used for treatment of early stage sleeping sickness, in a murine model. Mice were fed daily on a diet containing 0.50 mg aflatoxin/kg body weight or a placebo. They were infected with Trypanosoma brucei rhodesiense on day 7 post-aflatoxin exposure and then treated with one of 6 different doses of suramin (4.0, 4.5, 5.0, 5.5, 6.0 and 6.5 mg/kg body weight) at the onset of parasitemia. The mice were fed on aflatoxin diet for 30 days and the curative dose values (CD50, 75, and 90) computed and compared using a... Palavras-chave: Aflatoxin B1; Trypanosomiasis; Suramin efficacy; Mice. Ano: 2011 URL: http://ir.obihiro.ac.jp/dspace/handle/10322/3130 Effects of tea on survival rates and liver pathology of Trypanosoma brucei brucei infected mice Provedor de dados: 19 Autores: Mbuthia, S.K; Wachira, N.W; Ngure, R.M; Ouma, J; Kagira, J.M. The current study investigated the effects of different types of Kenyan tea extracts on the pathogenesis of Trypanosoma brucei brucei in a Swiss White mice model. Following infection with trypanosomes, the mice were monitored for survival and liver pathology. Tea significantly (P<0.05) enhanced the survival rate of tea treated mice. Additionally, in tea treated but infected mice, there was reduction in infiltration of inflammatory cells into the periportal and parenchymal regions as well as hepatocyte cell damage compared to the infected untreated animals. Green and white teas were superior in most of the above effects while black tea and oolong teas had the least effects. The tea extracts were more efficacious than dexamethasone in prolonging the life... Palavras-chave: Inflammation; Liver pathology; Survival rate; Tea; Trypanosomiasis. Ano: 2011 URL: http://ir.obihiro.ac.jp/dspace/handle/10322/3094 Aggravation of pathogenesis mediated by aflatoxin B1 in mice infected with Trypanosoma brucei rhodesiense Provedor de dados: 19 Autores: Kibugu, J.K; Makumi, J.N; Ngeranwa, J.J.N; Kagira, J.M; Gathumbi, J.K; Mwangi, J.N. Aflatoxins are known to alter the pathogenesis of many infectious diseases, but such effects have not been evaluated in trypanosome infections. The aim of the present work was to assess the effects of aflatoxin B1 on the pathogenesis of Trypanosoma brucei rhodesiense infection using a murine model. Mice fed on 0.50 mg/kg aflatoxin b. wt. were infected with T. b. rhodesiense and compared to trypanosome infected and uninfected aflatoxin-fed controls. The clinical and pathological changes were determined and the quantitative data statistically analysed using standard methods. The results showed that infected aflatoxin-fed mice had pronounced dyspnoea, significantly (P<0.05) reduced survival, extreme emaciation, pronounced macrocytic normochromic anaemia...
