Avian Aquatic Reservoirs and Zoonotic Potential of Helicobacter spp. in Wetlands from the Southern Caribbean Sea.
Article in Current microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Helicobacter species are increasingly recognized in environmental reservoirs, yet their prevalence and diversity in tropical wetland ecosystems remain poorly understood. This study aimed to assess the prevalence, distribution, and diversity of Helicobacter spp. in a tropical wetland ecosystem, specifically within the Cuare Wildlife Refuge, Venezuela, focusing on waterbirds and associated aquatic matrices. We collected samples from avian faeces, water, plankton, oysters, soils, and microbial mats during two periods (October/2011 and March/2012). Analysis involved culture in HP selective medium, genus-specific PCR, 16S rRNA gene sequencing, phylogeny and water quality assessment. Helicobacter DNA was detected in 57% of samples (n = 148), with varying prevalence: water (94%), plankton (100%), oysters and soils (80%), microbial mats (50%), and avian faeces (42%). Prevalence in bird faeces was higher in resident (69%) than migratory (41%) species and showed a positive correlation with water salinity in October 2011 (r = 0.94, p < 0.05). Despite urease activity, all culture attempts on selective medium failed. Phylogenetic analysis revealed sequences clustering within H. pylori, H. pametensis, H. kayseriensis, H. brantae, and H. pullorum-related clades, alongside potentially novel lineages, highlighting significant diversity and zoonotic potential. Elevated enterococci levels (> 35 MPN/100 mL), exceeding guideline values, suggest sewage inputs and threats to this wildlife habitat. These findings identify waterbirds as carriers and wetlands as reservoirs for diverse commensal, pathogenic and zoonotic Helicobacter species in a relevant marine protected area of the Caribbean Sea.
