Insight into the genetic diversity of Anaplasma marginale in cattle from ten provinces of China.
Article in Parasites & vectors, 2017. 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
backgroundAnaplasma marginale is an important tick-transmitted rickettsial pathogen of cattle, with worldwide distribution and an important economic impact. The genetic diversity of A. marginale strains has been extensively characterized in different geographical regions throughout the world, while information is limited on studies in China. This study was carried out to determine the prevalence and genetic diversity of A. marginale strains in cattle from ten provinces of China.
methodsA total of 557 blood samples from cattle were collected and screened for the occurrence of A. marginale by PCR based on the msp4 gene. The partial msp1a gene containing tandem repeat sequences was further amplified from msp4 positive samples. The Msp1a amino acid repeats were identified, and genetic variation of A. marginale strains was characterized based on the variation in the repeated portion of Msp1a.
resultsOur results showed that 31.6% of 557 cattle were positive for A. marginale. The infection rates of A. marginale varied considerably from 0 to 96.9% in different sampling regions. Sequence analysis revealed that two msp4 sequence variants of A. marginale exist in cattle. One hundred and three msp1a sequences were obtained and permitted to identify 42 Msp1a tandem repeats, 21 of which were not previously published for A. marginale. Moreover, 61 A. marginale genotypes were identified based on the structure of Msp1a tandem repeats.
conclusionsAnaplasma marginale is widely distributed in China and a high prevalence of infection was observed in cattle. The geographical strains of A. marginale were molecularly characterized based on the structure of Msp1a tandem repeats. Forty-two Msp1a tandem repeats and 61 genotypes of A. marginale were identified. This study, for the first time, revealed the genetic diversity of A. marginale strains in cattle in China.
