1 · What the graph read from it

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.

2 · The registry

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

Moraxella bovoculi has been isolated frequently from cattle with Infectious bovine keratoconjunctivitis (IBK). Two diverse genotypes of M. bovoculi, 1 and 2 were identified based on whole genome sequence analysis. It is essential to discriminate between the two genotypes to frame prevention and control measures. The whole genome of M. bovoculi TN7 was sequenced and compared to other M. bovoculi strains available in the NCBI database. M. bovoculi TN7 was found to be genotype 1, had an RTX toxin operon and pilA gene that are the known virulence factors in related Moraxella sp., but lacked antimicrobial resistance genes. M. bovoculi was found to have an open pangenome with 4051 (75.31%) accessory genes, and the addition of each new genome adds 18 genes to the pangenome. Comparison of pilin protein amino acid sequences revealed three new sequence types. Furthermore, the presence of linx, nagL, swrC and mdtA genes was found to be genotype 1 specific, whereas hyaD, garR, gbsA, yhdG, gabT, iclR, higB2, hmuU, hmuT and hemS were found only in genotype 2. Polymerase Chain Reaction (PCR) primers were designed and evaluated on strain TN7 plus seven additional strains accessible to us that had not been whole genome sequenced. This initial evaluation of the designed primers for the linX and hyaD genes produced the expected banding patterns on PCR gels for genotypes 1 and 2, respectively, among the 8 strains. The genotype-specific genes identified in this study can be used as markers for accurate diagnosis of genotype 1 isolates and this can aid in the development of autogenous or other molecular vaccines for treatment of infectious bovine keratoconjunctivitis (IBK) in resource-limited research settings.
