Understanding the biology of Babesia bovis
2017Bovine babesiosis caused by the protozoan parasite Babesia bovis remains a significant cause of avoidable economic loss to the livestock industry in many countries, including Australia. The precise mechanisms by which this parasite causes severe disease in susceptible cattle are not well understood, however, it is clear that pathophysiologically ...

The three ribosomal DNA (rDNA) units have been cloned from an Australian isolate of Babesia bigemina. The organization of the units is very similar to that reported for a Mexican isolate of B. bigemina. In Babesia canis four rDNA units have been identified. Both Babesia rodhaini and Babesia microti contain two different rDNA units.

Cross-reactivity between Babesia bovis and B. bigemina becomes a problem in discrimination of the two infections in endemic areas where the two species usually occur in association. With the aim of identifying candidate proteins for use as specific diagnostic tools, culture-derived components of three geographically different stocks of B.

Sera from cattle infected with Babesia bovis were found to contain antibodies to phosphatidyl-serine (PS), a negatively charged phospholipid normally found on the internal membrane of erythrocytes. In contrast, no autoantibodies were detected following Babesia bigemina infection indicating that the autoimmunity is not genus specific.

Immunodominant T-cell antigens and epitopes ofBabesia bovisandBabesia bigemina
Annals of Tropical Medicine & Parasitology, 1998Despite convincing evidence that T cells are critical for both cellular and humoral immunity against haemoprotozoan parasites, the difficulty of performing meaningful experiments in cattle that would define the role of T cells in immunity to Babesia spp. has impeded research in this area.

Serological responses of field cattle (260) on a farm in KwaZulu-Natal, South Africa were determined before and after vaccination with the commercial Babesia bovis live-blood vaccine, using the indirect fluorescent antibody test (IFAT). All the cattle tested negative for B.

Water Buffalos as Carriers of Babesia bovis in Argentina
Annals of the New York Academy of Sciences, 2008The tick‐transmitted hemoprotozoan Babesia bovis is a major causative agent of bovine babesiosis, an often fatal disease of cattle. The disease is widespread in the northeastern region of Argentina, where an increasing part of the livestock is composed of water buffalos.

Babesiosis (Babesia bovis) Stability in Unstable Environments
Annals of the New York Academy of Sciences, 2000Abstract: Enzootic stability (herd immunity) in bovine babesiosis occurs when the rate of transmission (inoculation rate) of Babesia spp by the tick vector is sufficient to immunize a majority of susceptible calves before the loss of calfhood resistance. The effect of three tick (Boophilus microplus) control strategies (none, threshold, and strategic)

Continuous cultivation of the bovine hemoparasites Babesia bovis and Babesia bigemina was developed as an in vitro microtest to assess parasite susceptibility to babesicidal compounds. Reproducibility of parasite multiplication rates was independent of culture size, making it possible to use a microscale of 100 microliters for each test sample ...
