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

Actinobacillus pleuropneumoniae (APP) is the etiological agent of porcine pleuropneumoniae (PP), a high contagious respiratory disease with significant impact on the swine industry in both clinically and economically. Despite of the several attempts to control APP, the emergence of novel serotypes and antimicrobial resistance (AMR) strains highlights the importance of monitoring the genetic characteristics of APP at single nucleotide level. Despite the importance of genomic surveillance of APP to develop effective control strategies, genetic information on the recent Korean isolates of APP is not available at whole genome level. Therefore, in this study, six APP strains were isolated from porcine lungs with characteristic lesions of PP from 2022 to 2024. And their whole genomic sequences, serotypes, virulence factors, and AMR traits were investigated using combined short- and long-read sequencing methods. In silico PCR serotyping identified the isolates as serotype 1, 7, and 15, while one isolate was non-typeable. Multiple AMR genes including Hinf_PBP3_BLA, Ecol_EFTu_PLV, tet(B), tet(O), tetR, sul2, aph(3'')-Ib, aph(6)-Id, and aph(3')-Ia were detected. Also, these genes were located with adjacent to mobile genetic elements, suggesting the possibility of horizontal gene transfer. Phylogenetic comparison with 40 global APP complete genomes, presented that Korean isolates were closely related with China and Switzerland strains. This study provides the whole genome sequences based genetic characterization on the recent Korean isolates of APP, and this study emphasizes that continuous monitoring of APP genomic variation to support effective control of porcine pleuropneumoniae.
