Prevalence of Campylobacter spp. in Raccoon Dogs and Badgers in Miyazaki Prefecture, Japan.
Article in EcoHealth, 2021. 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
A total of 55 samples of intestinal contents from 28 raccoon dogs (Nyctereutes procyonoides) and 27 badgers (Males anakuma) in Miyazaki prefecture, Japan, were examined for the presence of Campylobacter species. C. jejuni and C. upsaliensis were isolated from 3.6% (n = 1) and 75% (n = 21) of raccoon dogs, respectively. In contrast, no Campylobacter spp. was isolated from the badgers examined. The C. upsaliensis isolates were subjected to antimicrobial susceptibility testing against 8 antimicrobial agents. This revealed that most of the isolates from raccoon dogs were susceptible to the antimicrobial agents examined, whereas strains isolated from healthy dogs in Miyazaki prefecture, showed high rates of resistance. Virulence genes (flaA, cadF, ciaB, cdtA, cdtB, and cdtC) were present in the C. jejuni isolate from a raccoon dog, with the exception of flaB. By contrast, all these virulence genes examined were present in all C. upsaliensis strains isolated from raccoon dogs and dogs. The genetic diversity of those isolates based on the nucleotide sequences of 7 housekeeping genes (adk, aspA, atpA, glnA, glyA, pgi, tkt) was compared with that of C. upsaliensis strains isolated from dogs and strains selected randomly from humans and dogs deposited in the Campylobacter MLST database. The major cluster of raccoon dog strains was separated from both human and dog strains by phylogenetic tree analysis. These results suggest that raccoon dogs are a reservoir of C. upsaliensis and that isolates may represent a population different from that in humans and dogs. To our knowledge, this is the first study to have demonstrated a high prevalence of C. upsaliensis in raccoon dogs.
