Molecular detection of tick-borne pathogens in cattle ticks from the Lao People's Democratic Republic.
Article in Parasites & vectors, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTick-borne pathogens threaten livestock health and productivity in Southeast Asia. Despite growing regional interest, epidemiological data from the Lao People's Democratic Republic (Lao PDR) remain insufficient and underreported.
methodsWe collected 227 ticks from 63 cattle across northern, central, and southern Lao PDR. Species were morphologically identified as Rhipicephalus microplus and Rhipicephalus sanguineus sensu lato and confirmed by sequencing of the cytochrome c oxidase subunit I gene. Pathogen screening was conducted via polymerase chain reaction (PCR), with sequence identities verified using the GenBank database. Multivariate analyses assessed regional variation.
resultsDetected pathogens included the apicomplexan protozoans Babesia bigemina (7%), Babesia bovis (2.6%), and Theileria sp. (10.6%) as well as the bacteria Anaplasma marginale (18.9%), Anaplasma sp. (2.2%), Ehrlichia sp. (6.6%), Ehrlichia minasensis (0.4%), and Aureimonas altamirensis (1.3%). Anaplasma marginale was the most prevalent. Codetections were common, with multiple ticks harboring two or more pathogens. Some double detection occurred more frequently than expected by chance.
conclusionsThis study presents the first comprehensive evidence of diverse tick-borne pathogens circulating in cattle ticks from Lao PDR, revealing high genetic similarity to globally recognized strains alongside distinct region-specific detection patterns. Notably, it also constitutes the first report of A. marginale, E. minasensis, B. bigemina, B. bovis, and Theileria sp. in cattle ticks in the country. These findings underscore the urgent need for integrated tick and pathogen surveillance within a One Health framework, with significant implications for regional disease monitoring, livestock health management, and zoonotic risk mitigation.
