Biometrical alterations of Trypanosoma evansi isolate in laboratory rodents.

Repositório Alice

DAVILA, A. M. R.; RAMIREZ, L.; SILVA, R. A. M. S..

Biometrical alterations in a horse Trypanosoma evansi isolate were observed when passaged in laboratory rodents. The major parasite transformation observed was the increase in the total length as a consequence of an increase in some parasite measurements. These transformations probably occurred as a consequence of a host change from horse to rodents. No kinetoplastic forms were observed.

Canine trypanosomiasis: etiology of infection and implications for public health

J. Venom. Anim. Toxins incl. Trop. Dis.

Eloy,LJ; Lucheis,SB.

Canine trypanosomiasis, caused by protozoans of the genus Trypanosoma, is divided into two primary types: the American form (Chagas disease), due to Trypanosoma cruzi infection, and the African form (sleeping sickness or surra), provoked by Trypanosomaevansi. This disease was originally enzootic and affected only wild animals, including mammals and birds, which served as reservoirs. Later, it spread to domestic animals such as horses, cattle and dogs. The disease became a zoonosis when contact between rural inhabitants and natural Trypanosoma foci occurred, due to ecological imbalances and increasing migration. Dogs are significantly involved in this context, because they are the main domestic animals and participate in the transmission and maintenance...

ABSTRACT: This research investigated the pattern of antibody response by means of enzyme linked immunosorbent assay (Elisa) and indirect fluorescent antibody test (IFAT) through the course of experimental Trypanosoma evansi infection in dogs. Clinical and parasitological features were also studied. The average prepatent period was 11.2 days and parasitaemia showed an undulating course. Biometrical study of parasites revealed a mean total length of 21.68mm. The disease was characterized by intermittent fever closely related to the degree of parasitaemia and main clinical signs consisted of pallor of mucous membrane, edema, progressive emaciation and enlargement of palpable lymph nodes. Diagnostic antibody was detected within 12 to 15 days and 15 to...

Comparative polypeptide profiles of whole cell lysate antigens of Trypanosoma evansi isolated from three different hosts of eastern India

Diagnosis of Trypanosoma evansi by the polymerase chain reaction (PCR)

Laha, R; Sasmal, N.K; Bandyopadhyay, S.

Trypanosoma evansi from buffalo, cattle and horse isolates were purified by Diethylaminoethyl cellulose column chromatography. The purified trypanosomes from each sources were used separately for preparation of whole cell lysate antigens. A comparative study on polypeptide pattern of whole cell lysate antigens of these three isolates of T. evansi was studied. It showed a total of 11 dominant polypeptide bands with relative molecular weight ranging from 95 to 13 kDa, when resolved in 10% sodium dodecyl sulphate polyacrylamide gel electrophoresis and stained with Coomassie brilliant blue. Except some minor differences between the relative molecular weight of isolates in a particular region, the polypeptide profiles of these three isolates did not resolve any...

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...

Equine infectious anemia virus (EIAV) and Trypanossoma evansi are endemic in Brazilian Pantanal Biome,an important area for livestock production. In this sense, we evaluated the epidemiological single andco-infection effects of T. evansi and EIAV in naturally infected horses in the southern Pantanal wetland byserological tests and hematological assays. Both higher seroprevalence and heath poor condition of thesampled animals were associated with differences in horse management between farms. We found thatthe negative animals for both infectious agents (NN) represented the major group in F1 (37%), and thesmallest group in F2 (19%). Furthermore, we recorded higher EIAV seroprevalence (56%) in F2, comparedto F1 (38%). We observed that T. evansi infection was...

ABSTRACT: The course of experimental T. evansi infection in four dogs was followed for 82 days and hematological, biochemical and anatomopathological findings were studied. Infected animals showed progressive decrease in red blood cell count and hemoglobin concentration, leading to anemia which persisted from the third week post-infection until the end of the study. Leucopenia and neutropenia were observed between weeks 2 and 5 of the infection. The infected dogs developed hyperproteinemia and a decrease in the albumin:globulin ratio was observed. Aspartate aminotransferase and alamine aminotransferase levels increased significantly in infected dogs in comparison to control dogs. Histological changes observed in all infected animals consisted of lymphoid...

O presente trabalho relata duas infecções naturais por Trypanosoma evansi em cães, que vieram a óbito no município de Uruguaiana, RS. Os animais oriundos da zona rural foram recebidos no hospital veterinário da Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS), em diferentes datas, apresentando apatia, febre e aumento dos linfonodos submandibulares. No esfregaço sangüíneo, foram identificadas formas flageladas pertencentes à espécie T. evansi. A verificação desses casos serve de alerta aos proprietários de animais e médicos veterinários para a presença da doença na região e salienta a necessidade de maiores investigações na epidemiologia da parasitose e criação de medidas profiláticas que evitem novas infecções.
