Abstract

Babesia bovis is an intra-erythrocytic tick-transmitted apicomplexan protozoan parasite. It has a complex lifestyle including asexual replication in the mammalian host and sexual replication occurring in the midgut of host tick vector, typically, Rhipicephalus microplus. Previous evidence showed that certain B. bovis genes, including members of 6-Cys gene family, are differentially expressed during tick and mammalian stages of the parasite's life cycle. Moreover, the 6-Cys E gene is differentially expressed in the T3Bo strain of B. bovis tick stages, and anti 6-Cys E antibodies were shown to be able to inhibit in vitro growth of the phenotypically distinct B. bovis Mo7clonal line. In this study, the 6-Cys E gene of B. bovis T3Bo strain was disrupted by transfection using a plasmid containing 6-Cys gene E 5' and 3' regions to guide homologous recombination, and the egfp-bsd fusion gene under control of a ef-1α promoter, yielding a B. bovis clonal line designated 6-Cys EKO-cln. Full genome sequencing of 6-Cys EKO-cln parasites was performed and in vitro inhibition assays using anti 6-Cys E antibodies. Full genome sequencing of 6-Cys EKO-cln B. bovis demonstrated single insertion of egfp-bsd gene that disrupts the integrity of 6-Cys gene E. Undistinguishable growth rate of 6-Cys EKO-cln line compared to wild-type 6-Cys E intact T3Bo B. bovis strain in in vitro cultures indicates that expression of gene 6-Cys E is not essential for blood stage replication in this strain. In vitro inhibition assays confirmed the ability of anti-6 Cys E antibodies to inhibit the growth of the wild-type Mo7 and T3Bo B. bovis parasites, but no significant inhibition was found for 6-Cys EKO-cln line parasites. Overall, the data suggest that the anti-6 Cys E antibody neutralising effect on the wild type strains is likely due to mechanical hindrance, or cross-reactivity, rather than due to functional requirements of 6-Cys gene E product for survival and development of the erythrocyte stages. Further investigation is underway to determine if the 6-Cys E protein is required for replication and sexual stage development of B. bovis during tick stages.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 03 May 2017.
All research outputs
#7,184,668
of 9,763,361 outputs
Outputs from Parasites & Vectors
#1,802
of 2,767 outputs
Outputs of similar age
#171,687
of 262,750 outputs
Outputs of similar age from Parasites & Vectors
#116
of 140 outputs
Altmetric has tracked 9,763,361 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,767 research outputs from this source. They receive a mean Attention Score of 4.2. This one is in the 26th percentile – i.e., 26% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 262,750 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 140 others from the same source and published within six weeks on either side of this one. This one is in the 10th percentile – i.e., 10% of its contemporaries scored the same or lower than it.
