Studies on the pathogenesis of Babesia argentina and Babesia bigemina infections in splenectomised calves

Zeitschrift f�r Parasitenkunde, 1972
The sequence of pathological changes in both B. argentina and B. bigemina infections of splenectomised calves are described. Renal damage preceded hepatic damage by one to two days. BUN levels increased 2-4 times; SGOT increased 4 times. Unconjugated bilirubin levels increased from {reversed tilde equals} 0.30 mg% to a peak 4.12 mg%±1.90 mg% in one ...

The immune responses to antigenic variants of Babesia bigemina in the bovine

Research in Veterinary Science, 1978
Four Babesia bigemina stabilates were used to determine the immune response of cattle to acute and chronic blood- and tick-borne infections. Thirty-two intact calves were divided into 16 groups of two and each calf was inoculated with infective B bigemina erythrocytic stabilates.

Effect of Mycobacterium phlei on the development of immunity to Babesia bigemina

Veterinary Parasitology, 1996
The immunomodulatory role of Mycobacterium phlei against intracellular blood protozoan Babesia bigemina was demonstrated following experimental immunisation and challenge in bovine calves. A lysate of erythrocytes infected (6 x 10(9)) with B. bigemina was used as a source of dead antigen either with Freund's complete adjuvant (FCA) or with a ...

Fluorescent Antibody Tests for Babesia bigemina and B. berbera

Research in Veterinary Science, 1972
Summary The indirect fluorescent antibody method has been used to detect antibodies in cattle against Babesia bigemina and B. berbera, and as a means of identifying Babesia species in internal organs of cattle. Test antigen was prepared from washed, hacmolyzed blood in the case of B. bigemina, and from infected kidney in the case of B.

Development of Tick Gut Forms of Babesia bigemina In Vitro

Journal of Eukaryotic Microbiology, 1998
Development of a laboratory cultured tick‐transmissible strain of Babesia bigemina was followed in vitro after addition of gut material from engorged female Boophilus microplus ticks and incubation at 37° C. Sequential development of stages, from intraerythrocytic strahlenkörper through multiplication to the fusion of what is assumed to be two gametes,

A study of autoantibodies to phosphatidyl-serine in Babesia bovis and Babesia bigemina infections in cattle

Veterinary Immunology and Immunopathology, 1994
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.

Immunochemical characterization of in vitro culture-derived antigens of Babesia bovis and Babesia bigemina

Veterinary Parasitology, 1998
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.

Improved Molecular Tools for Detection of Babesia bigemina

Annals of the New York Academy of Sciences, 2008
Molecular detection of Babesia bigemina involves a nested PCR protocol and reverse line blot hybridization (RLBH) assay based on the 18S gene. In this study, we report the development of molecular tools for improving B. bigemina detection in bovine blood—a one‐step PCR assay based on the amplification of rap‐1a paralogous and a new RLBH Babesia spp ...

Detection and quantification of Babesia bovis and Babesia bigemina using different target genes

Research in Veterinary Science
Molecular assays have been widely used for the detection and quantification of bovine babesiosis due to their high sensitivity and specificity. However, variations in the sensitivity of pathogen detection may occur depending on the selected target gene. Thus, this study aimed to compare the detection sensitivity (DS) of Babesia bovis and B.

Molecular detection and identification of Babesia bovis and Babesia bigemina in cattle in northern Thailand

Parasitology Research, 2012
Although Babesia bovis and Babesia bigemina infections cause economic losses in the cattle industry in northern Thailand, there is inadequate information on Babesia isolates present in the area. Therefore, to determine the prevalence and genetic relationship between Babesia isolates, we screened 200 blood samples of cattle from Chiang Rai, Chiang Mai ...
