During 2009-2012, wild animals were sampled in two areas within the Amazon biome of Brazil, in the states of Mato Grosso and Pará. Animal tissues and blood were molecularly tested for the presence of Piroplasmida (genera Babesia, Theileria, Cytauxzoon) or Hepatozoon DNA. Overall, 181 wild animals comprising 36 different species (2 reptiles, 5 birds, and 29 mammals) were sampled. The following P...

Blood specimens were received from five cases in which young adult giraffe, from different geographic origins in South Africa, showed sudden onset of disease and subsequently died. Additional specimens from two translocated giraffe, as well as one specimen from a roan antelope, were also included in the study. Blood slides from some of these animals showed the presence of piroplasms. DNA was ex...

Forty Theileria schizont-infected lymphocyte culture isolates from Zimbabwe were characterized using a panel of antischizont monoclonal antibodies (MAbs) and 4 Theileria parva DNA probes containing cloned extrachromosomal element, Tpr repetitive, ribosomal and telomeric sequences. The Theileria isolates were assigned as T. parva or T. taurotragi on the basis of reactivities with MAbs and restri...

Bovine theileriosis is an important tick-borne disease caused by intraerythrocytic parasites from genus Theileria. This study sought to detect the theileriosis among cattle and buffaloes using molecular and microscopic tests in West Azerbaijan, Iran. For this purpose, 484 blood samples from 193 cattle and 291 buffaloes were collected during March to July 2014. The breed, gender, age, and habita...

Infection of bovine leucocytes by Theileria annulata results in establishment of transformed, infected cells. Infection of the host cell is known to promote constitutive activation of pro-inflammatory transcription factors that have the potential to be beneficial or detrimental. In this study we have compared the effect of LPS activation on uninfected bovine leucocytes (BL20 cells) and their Th...

To determine whether the major histocompatibility complex (MHC) phenotype of cattle could affect the parasite strain specificity of immunity to Theileria parva by influencing the antigenic specificity of Theileria-specific cytotoxic T lymphocytes (CTL), we investigated the parasite strain specificity of Theileria-specific CTL clones derived from cattle of different class I MHC phenotypes. Thirt...

A new pathogenic Theileria species transmitted by Haemaphysalis qinghaiensis was identified in the Northwestern part of China and was shown to be highly pathogenic for small ruminants. The present article aimed at identifying merozoite antigens that might be suitable for developing diagnostic methods and designing a potential vaccine. Absence of other theilerial or babesial infections was confi...

background: babesiosis and thosis are parasitic tick-borne diseases that cause a lot of economic loss in livestock industry. objectives: the purpose of the present study was to detect babesia and theileria infection in goats and and vector ticks in goats in mashhad. methods: one hundred blood samples of goats and 246 ticks were collected from some suspected flocks with history of piroplasmosis....
