Genetic diversity, serotype, and antimicrobial profiles of Riemerella anatipestifer isolated from ducks and chickens in Thailand.
Article in Poultry science, 2026. 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
Riemerella anatipestifer, which causes New Duck Syndrome, poses a significant threat to poultry production, causesing respiratory distress, neurological signs, and septicemia primarily in ducks and occasionally chickens. R. anatipestifer outbreak control requires knowledge about their genetic diversity, serotypes, and antibiotic profiles, which are currently unavailable. In this study, R. anatipestifer was isolated from ducks and chickens in Thailand between 2021 and 2023 to characterize their genetic relatedness, antimicrobial profiles, and resistance genes. Seven different serotypes were identified in isolates from ducks. Non-typable strains were the most prevalent, followed by serotypes 7, 10, 1, 5, 11, and 17. However, only serotype 1 was identified in isolates from chickens. Antimicrobial susceptibility testing revealed high resistance to colistin and broad minimum inhibitory concentration (MIC) ranges for β-lactams, aminoglycosides, chloramphenicol, sulfamethoxazole, and trimethoprim. Of the 17 representative isolates analyzed by WGS, the most prevalent resistance genes were tet(X2) and lnu(I). Phylogenetic analysis based on core-genome single nucleotide polymorphisms (SNPs) categorized the isolates into four main clusters. Most of Thai isolates from both ducks and chickens clustered together, indicating the circulation of endemic strains within the region. This is the first comprehensive study of R. anatipestifer isolated from ducks and chickens in Thailand. This research illustrates the value of enhancing basic biosecurity and movement control among farms. The data also provide a valuable foundation for the development of antibiotic use guidelines and vaccines, which will enhance the judicious and minimal use of antibiotics in poultry production.
