A cDNA expression library of Babesia gibsoni was screened with the serum collected from a dog experimentally infected with B. gibsoni. A novel antigen sharing homology with secreted antigen 1 of B. gibsoni was isolated. The genomic analysis indicated that the BgSA3 gene exists as multicopies in the genome of B. gibsoni. The putative peptide encoded by the BgSA3 gene showed some characteristics ...
A cDNA encoding the rhoptry-associated protein 1 (RAP-1) homologue was obtained by immunoscreening an expression library prepared from Babesia gibsoni merozoite mRNA. The complete nucleotide sequence of the gene was 1740bp. Computer analysis suggested that the sequence contains an open reading frame of 1425bp encoding an expected protein with a molecular weight of 52kDa. Based on the sequence s...
In the current study, a total of 214 blood samples from dogs in and around Ludhiana, Punjab (India), suspected for canine babesiosis were examined with conventional and molecular assays. Examination of Giemsa-stained peripheral thin blood smears revealed an overall prevalence of 7.47% (16/214) for canine babesiosis encompassing 0.93% (2/214) of large Babesia and 6.54% (14/214) of Babesia gibson...
A cDNA expression library prepared from Babesia gibsoni merozoite mRNA was screened with B. gibsoni-infected dog serum. cDNA encoding a 50-kDa protein was cloned and designated the P50 gene. The complete nucleotide sequence of the P50 gene was 1,922 bp. Computer analysis suggested that the sequence of the P50 gene contained an open reading frame of 1,401 bp with a coding capacity of approximate...
Babesia gibsoni is a tick-borne apicomplexan parasite of dogs that often causes fever and hemolytic anemia with highly variable clinical outcome. In this study, we sequenced the 254bp Internal Transcribed Spacer 1 region (ITS1) of 54 B. gibsoni isolates from 14 different geographical regions of Japan. The 54 isolates shared high sequence identity with each other and with B. gibsoni isolates rep...
The Babesia gibsoni heat shock protein 90 (BgHSP90) gene was cloned and sequenced. The length of the gene was 2,610 bp with two introns. This gene was amplified from cDNA corresponding to full length coding sequence (CDS) with an open reading frame of 2,148 bp. A phylogenetic analysis of the CDS of HSP90 gene showed that B. gibsoni was most closely related to B. bovis and Babesia sp. BQ1/Lintan...
To determine the distribution of Babesia gibsoni infection in dogs in the eastern part of Japan, an epidemiological survey of dogs suspected of having B. gibsoni infection was attempted using the polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA). Thirty-five of 115 such dogs (30.4%) were positive by PCR and/or ELISA. The 35 positive dogs consisted of 28 Tosa dogs, 4 ...
Canine babesiosis is a tickborne, protozoal, haemoparasitic disease. Babesia organisms are frequently classified as either large (B. canis) or small gibsoni). The aim of this study was an attempt to detect B. gibsoni DNA in blood samples taken from dogs suspected suffering tick-borne diseases. 216 were tested using PCR, which, 99 them canisDNA detected, whereas 3 detected. Positive PCR results ...
In this study, we attempted to detect Babesia gibsoni in blood smears and formalin-fixed, paraffin-embedded tissues obtained from B. gibsoni-infected dogs using in situ hybridization. Using a digoxigenin-conjugated deoxyribonucleic acid (DNA) probe, both intraerythrocytic and exoerythrocytic parasites in the culture could be specifically stained in blood smears fixed with 4% phosphate-buffered ...
In 73 gDNA samples from Babesia gibsoni-infected dogs, the M121I variant population was measured by using allele-specific real-time PCR. Although the mechanism of atovaquone against B. gibsoni has not been clearly identified, it is reported that the mitochondria cytochrome b gene of the atovaquone-resistant B. gibsoni had a single-nucleotide substitution at nt363 (G to T), which resulted in the...
