Three antimalarial drugs, artesunate, pyrimethamine, and pamaquine, were evaluated for their growth-inhibitory effects against Babesia equi and Babesia caballi in in vitro culture. B. equi was more resistant to pyrimethamine than B. caballi. B. equi was also found to be more sensitive to artesunate and pamaquine than B. caballi. Of the three compounds, pyrimethamine gave the most promise for in...

Both Babesia equi and Babesia caballi are endemic in large parts of South Africa. Attempts were made to obtain pure local isolates of both B. equi and B. caballi for the purpose of developing serological tests to study the epidemiology of equine babesiosis in this country. The indirect fluorescent antibody test was used to screen horses for B. equi and B. caballi in an endemic area. Seven horse...

The prevalence of equine piroplasmosis caused by Babesia equi and Babesia caballi in northeast China has remained unknown, although the People's Republic of China is recognized as an endemic country for the diseases. In the present study, we investigated the prevalence of equine piroplasmosis in Jilin province, a part of northeast China. A total of 111 serum samples were taken from horses in ea...

A quantitative real-time polymerase chain reaction (qPCR) assay using a TaqMan minor groove binder (MGB) probe was developed for the detection of Babesia caballi infection in equids from South Africa. Nine previously published sequences of the V4 hypervariable region of the B. caballi 18S rRNA gene were used to design primers and probes to target unique, conserved regions. The B. caballi TaqMan...

Serologically negative horses, as determined with the indirect fluorescent antibody test (IFA), were infected with Babesia equi and 60 days later with Babesia caballi. The only clinical signs of disease observed in these animals were a febrile reaction and slight icterus. Haematological changes included a drop in haematocrit and haemoglobin concentration, as well as lowered platelet counts. The...

BACKGROUND Babesia spp. are tick-borne protozoan hemoparasites and the second most common blood-borne parasites of mammals, in particular domestic animals. We used the Clustal Multiple Alignment program and 18S rRNA gene sequences of 22 Babesia species from GenBank to develop a PCR that could detect a wide variety of Babesia spp. in a single reaction. The pan-Babesia FRET-qPCR we developed reli...

Equine piroplasmosis is a tick-borne disease caused by intra-erythrocyte protozoa, Theileria equi and Babesia caballi. The present study aimed to detect piroplasm infection in horses in Kurdestan Province, Iran, through molecular and microscopic approaches.n this study, 186 blood samples were randomly collected from horses of five regions of Kurdestan Province. The Tbs-S/Tbs-A primer set was us...

The objective of this study is to investigate the seroprevalence of equine piroplasmosis in China. A total of 1990 sera were collected from clinically healthy horses in various districts located in ten different provinces of China and examined by using indirect enzyme-linked immunosorbent assays (ELISAs) with recombinant Theileria equi (T. equi) merozoite antigen 2 (rEMA-2) and Babesia caballi ...

Equine babesiosis is a hemoprotozoan tickborne disease with worldwide distribution and caused by Theileria equi and Babesia caballi. This study was conducted to determine the seroprevalence of T. equi and B. caballi infection in Turkoman breed horses in North Khorasan Province of Iran. Blood samples were collected from 100 apparently healthy horses and examined by microscopy and indirect immuno...

Background Equine piroplasmosis is caused by two haemoprotozoan parasites: Babesia caballi and Theileria equi. Negative economic impact on international trade has been associated to endemic sites. This is the reason why carrier detection requires reliable diagnostic methods. Various diagnostic modalities can be used alone or in combination including PCR. However, genetic variation of commonly u...
