Transmission and diagnosis of equine babesiosis in South Africa

Memorias do Instituto Oswaldo Cruz, 1992
The transmission and prevalence of Babesia equi and B. caballi are being studied. Rhipicephalus evertsi mimeticus an ixodid tick from Namibia was identified as a new vector of B. equi, however, R.

Molecular genotyping of Babesia caballi

Veterinary Parasitology
Babesia caballi is an intra-erythrocytic parasite causing equine piroplasmosis. Three B. caballi genotypes (A, B, and C) have been identified based on the 18 S rRNA and rhoptry-associated protein (rap-1) gene sequences. These variant parasite genotypes compromise the diagnostic utility of the WOAH-recommended serological assays in declaring horses free

DNA probes for the detection of Babesia caballi

Parasitology, 1991
A genomic library of Babesia caballi DNA was constructed in the plasmid vector pUC13. The specificity of the clones for B. caballi was established by the lack of hybridization to Babesia equi, Babesia bovis, Babesia bigemina and equine DNA. Two probes, pBC11 and pBC191, were isolated that could detect 0·25 ng and 0·125 ng of B.

Serological detection and risk factors for equine piroplasmosis in the semiarid region of Pernambuco, Northeastern Brazil

Revista Brasileira de Parasitologia Veterinária, 2019
Equine piroplasmosis, an economically important disease in horses, has so far not been reported in Pernambuco state, Brazil. This study aimed to evaluate the seroprevalence of anti-Babesia caballi and anti-Theileria equi antibodies based on the detection

Identification of diagnostic antigens for South American Babesia caballi infections

International Journal for Parasitology, 1994
Sera from 60 horses held in breeding herd in Brazil were examined monthly by ELISA, immunofluorescence antibody test (IFAT) and Western blot. All foals had maternal antibodies detectable by ELISA and IFAT, and sero-conversion took place between the 2nd and 5th month of age. The 48 and 50 kDa antigens were recognized first in the course of infection. Of

Molecular and serological detection of Theileria equi, Babesia caballi and Anaplasma phagocytophilum in horses and ticks in Maranhão, Brazil

Pesquisa Veterinária Brasileira
: Equine piroplasmosis is a tick-borne disease caused by the intraeytrhocytic protozoans Babesia caballi and Theileria equi. It has been reported as a main equine parasitic disease.

Translocation a potential corridor for equine piroplasms in Cape mountain zebra (Equus zebra zebra)

International Journal for Parasitology: Parasites and Wildlife, 2019
Translocation of animals in fragmented habitats is an important means of dispersal and gene flow, however, the movement of animals has led to the spread of various diseases globally and wildlife are often the reservoirs of these diseases. Currently, Cape

Molecular investigation of bacterial and protozoal pathogens in ticks collected from different hosts in Turkey

Parasites & Vectors, 2021
Background The emergence of tick-borne disease is increasing because of the effects of the temperature rise driven by global warming. In Turkey, 19 pathogens transmitted by ticks to humans and animals have been reported.

Genetic Variation of the -tubulin Gene of Babesia caballi Strains

Journal of Arthropod-Borne Diseases, 2017
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.
