The production of short stumpy and multinuclear trypanosomes in a Chinese strain of dyskinetoplastic Trypanosoma evansi maintained in rabbits and mice is described. Production of multinuclear trypanosomes was increased following passage through a reptile (gecko), in which the trypanosomes did not multiply, and transfer back to mice. The multinuclear trypanosomes showed more nuclei than flagella...

Six hundred and eleven random-source dogs (338 male, 273 female) one year of age or older, from six sections of the city of Recife, Pernambuco, were examined antemortem for circulating microfilariae Dirofilaria immitis and Dipetalonema reconditum adult heartworm (D. immitis) antigen, and examined postmortem for adult heartworms. The prevalence of heartworm infection was 2.3% (14/611), as determ...

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak bawang putih terhadap jumlah rata-rata eritrosit mencit yang diinfeksi Trypanosoma evansi. Isolat T. evansi digunakan berasal dari kasus surra di Buntok, Kalimantan Selatan tahun 2019 dan ekstraksi dilakukan dengan metode maserasi. Sampel sebanyak 30 ekor jantan strain Deutch Democratic Yokohama, bobot badan 25-30 gram per eko...

We compared two methods to generate polymorphic markers to investigate the population genetics of Trypanosoma evansi; random amplified polymorphic DNA (RAPD) and amplified restriction fragment length polymorphism (AFLP) analyses. AFLP accessed many more polymorphisms than RAPD. Cluster analysis of the AFLP data showed that 12 T.evansi isolates were very similar ('type A') whereas 2 isolates dif...

Pathogenic leptospiras (1,424) isolated from natural waters and wet soils in Malaysia comprised 29 different serovars (synonym serotypes). All except two of the serovars had been found previously in Malaysia. The exceptional serovars were werrasingha, an Autumnalis serogroup member originally isolated in Ceylon, and a new serovar designated evansi. Serovar evansi had serological affinities with...

The role of vitamin A was evaluated for its chemotherapeutic and chemoprophylactic action against Acanthocheilonema viteae infection in Mastomys coucha. Vitamin A was administered for 10 days, five days before infection and five days post infection. On day 0 experimental animals as well as controls were infected with L3, the infective stage. Establishment of the worms revealed significantly les...

Experimental Parasitology 40, 5-12. The effects of thermal stress on the numbers of circulating microfilariae of the filariid parasite, Dipetalonema viteue, in its host, the Mongolian jird, Meriones unguiculatus, was determi...

Wild animals are infected by diverse parasites, but how they influence host health is poorly understood. We examined the relationship of trypanosomatids and gastrointestinal parasites with health of wild brown-nosed coatis (Nasua nasua) from the Brazilian Pantanal. We used coati body condition and hematological parameters as response variables in linear models that were compared using an inform...
