Identification of Leptospira spp. in the animal-environment interface (swine-water) in pig production cycle.
Article in Tropical animal health and production, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
introductionLeptospirosis, caused by Leptospira spp., is a zoonosis with multiple hosts and reservoirs. Thus, the "One Health" approach must be addressed in order to guide prevention and control measures regarding this microorganism. There are few studies involving all stages of the pig production cycle and potential sources of infection such as water sources, which could represent a risk for local rural communities.
objectiveTo identify Leptospira spp. in the animal-environment interface (swine-water) in the pig production cycle. MATERIALS AND
methodsThe study was conducted in a swine farm in Puerto López in the department of Meta, Colombia. Swine blood samples (n = 65) were collected for microscopic agglutination test (MAT), while urine and water samples (n = 80) were tested for Leptospira using bacterial isolation, serotyping of the isolates, and polymerase chain reaction (PCR).
resultsA total of 58 (89.2%) porcine sera were positive for at least one Leptospira serogroup, with Grippotyphosa as the most frequent serogroup. Leptospira spp. were isolated in 25% (20/80) of the urine and water samples. Leptospira-positive cultures were 100% (20/20) identified within the genus Leptospira (rrl gene) and 50% (10/20) corresponded to pathogenic species (lipL32 gene) by PCR, and 45% (9/20) were positive to at least one antiserum. None of the direct urine and water samples was positive by PCR.
conclusionIt is suggested that the bacteria might be transmitted in the animal-environment interface in the pig production cycle.
