Quantitative PCR surveillance of Perkinsus marinus in Crassostrea virginica and Magallana gigas across the USA, Mexico, Brazil, and Korea.

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
Perkinsus marinus is a significant pathogen in oyster aquaculture with expanding host and geographic ranges. This study evaluated the prevalence and infection intensity of P. marinus in major oyster farming regions across the USA, Mexico, Brazil, and Korea using a quantitative PCR (P. marinus-specific TaqMan quantitative PCR assay, Pm-qPCR) assay. Eastern oysters (Crassostrea virginica) were sampled from 7 USA sites, while Pacific oysters (Magallana gigas) were collected from Mexico, Brazil, and Korea. Compared to conventional PCR, the Pm-qPCR assay demonstrated significantly higher sensitivity, detecting P. marinus in >80.0% of samples at most sites and up to 100.0% in Port Norris, USA. Lower prevalence was found in Wellfleet, USA (58.0%) and Korean sites (63.0%-70.0%). The lowest infection intensities (<1,000 copies) were recorded at a high-energy open-water site in Buan, Korea. The assay's specificity was confirmed using negative control oysters from Canada. These findings provide critical baseline data on P. marinus distribution and emphasize the superior diagnostic value of Pm-qPCR for early detection. As P. marinus spreads globally, sensitive and standardized tools like this assay are essential for disease surveillance and aquaculture biosecurity.
