Comparative study of binding of ovine complement factor H with different Borrelia genospecies.
Article in Folia microbiologica, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study presents the binding of ovine factor H (fH) by various serotypes of Borrelia and simultaneously correlates their complement resistance to sheep serum. Affinity ligand binding assay was employed to study the binding of borrelial proteins to ovine recombinant fH and its truncated forms (short consensus repeat, SCR 7 and SCRs 19-20). From a repertoire of 17 borrelial strains, only two strains showed affinity to sheep fH. A ~28-kDa protein of Borrelia burgdorferi sensu stricto (B. burgdorferi s.s., strain SKT-2) bound full-length fH as well as SCRs 19-20. This fH-binding protein was further identified as complement regulator-acquiring surface protein of B. burgdorferi (BbCRASP-1) by MALDI-TOF analysis. Surprisingly, a ~26-kDa protein of Borrelia bissettii (DN127) showed affinity to full-length fH but not to SCR 7 and SCRs19-20. In complement sensitivity assay, both strains-SKT-2 and DN127-were resistant to normal sheep serum. Significant complement resistance of two Borrelia garinii strains (G117 and T25) was also observed; however, none of those strains was able to bind sheep fH. Our study underscores the need of further exploration of fH-mediated evasion of complement system by Borrelia in domestic animals.
