Molecular characterization of Klebsiella pneumoniae in clinical bovine mastitis in 14 provinces in China.
Article in Veterinary research communications, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
The mastitis caused by Klebsiella pneumoniae (K. pneumoniae) is increasing in the dairy cows. To investigate the epidemic of K. pneumoniae of China, 131 strains were isolated from 495 clinical mastitis milk samples (26.5%) from 14 provinces in China. Among the isolates, K57 was the dominant serotype (45.0%) and 19 (14.5%) isolates were identified as hypervirulent K. pneumoniae (hvKP). The mrkA, entB, wabG and fimH genes were prevalent virulence genes while rmpA, magA, and ycf were not found in K. pneumoniae. Furthermore, K. pneumoniae had serious antibiotic resistance and multiple β-lactamase genes, including blaTEM, blaSHV, blaNDM, blaCTX-M, blaDHA, and blaKPC. Biofilm was an important factor in bacterial resistance and persistent infection, and 77.1% isolates could form biofilm. Although acylated homoserine lactone (AHL, a Gram-negative bacterial quorum sensing signal molecule) was not confirmed among the K. pneumoniae isolates, exogenous AHLs could reduce the biofilm formation ability of the K. pneumoniae strains. Three new ST types (ST6781, ST6782, and ST6783) were first identified in this study. The MLST phylogenetic tree showed the distribution of mastitis associated K. pneumoniae strains had no regular pattern, which confirmed high genomic diversity of mastitis associated K. pneumoniae. In conclusion, the high rate of isolation and serious antibiotic resistance of K. pneumonia were found in this study and indicated a potential threat to public health from the food chain.
