Babesia bovis: transcriptional analysis of rRNA gene unit expression.

Babesia bovis: the development of an expression oligonucleotide microarray.

The availability of a stage-specific Babesia bovis expression profile can facilitate the identification of candidate vaccine antigens. In addition, highly expressed genes during a particular developmental stage may suggest their relevance during that stage. In this study, we generated and validated a custom B. bovis high density oligonucleotide microarray that can be used to examine gene expres...

An outbreak of Babesia bovis infection in cattle and its control

Stable expression of a GFP-BSD fusion protein in Babesia bovis merozoites.

Transfection has been a valuable technique for elucidating gene function in many pathogens. While transient transfection of Babesia spp. has been reported previously, stable integration of exogenous genes in Babesia has proven difficult. In this study, a plasmid was designed to target integration of a gfp-bsd gene into the Babesia bovis ef-1alpha locus. Babesia bovis-infected erythrocytes of th...

Molecular and serologic evidence for Babesia bovis-like parasites in white-tailed deer (Odocoileus virginianus) in south Texas.

The current study was undertaken to determine if white-tailed deer in south Texas harbor Babesia bovis, a causative agent of bovine babesiosis. Blood samples from free-ranging white-tailed deer (Odocoileus virginianus) on two ranches in LaSalle and Webb Counties were screened for B. bovis and other hemoparasites by the polymerase chain reaction (PCR) to detect the piroplasm 18S rDNA. Serology w...

Expression and strain variation of the novel “small open reading frame” (smorf) multigene family in Babesia bovis

Small open reading frame (smorf) genes comprise the second largest Babesia bovis multigene family. All known 44 variant smorf genes are located in close chromosomal proximity to ves1 genes, which encode proteins that mediate cytoadhesion and contribute to immune evasion. In this study, we characterised the general topology of smorf genes and investigated the gene repertoire, transcriptional pro...
