Serosurveillance of Leishmania infantum in Zoo-Kept Animals in Spain.
Article in Zoonoses and public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionLeishmaniosis is a sand fly-borne zoonosis mainly caused by Leishmania infantum in Europe. Exposure to this protozoan has been widely reported in many domestic and wild species. However, epidemiological surveys evaluating the circulation of L. infantum in zoo-kept animals remain limited. This large-scale study aims to evaluate the seroprevalence of L. infantum in zoo-kept species in Spain as well as alterations in serum protein levels in L. infantum-seropositive individuals, to identify potential risk factors associated with L. infantum exposure, and to assess the dynamics of seropositivity in animals longitudinally sampled during the study period.
methodsBetween 2007 and 2023, serum samples from 429 zoo-kept animals belonging to 72 species were collected in nine zoos in Spain using convenience sampling. Additionally, 29 of these individuals from six of the tested zoos were also longitudinally sampled.
resultsAnti-L. infantum antibodies were detected in 22 (5.1%; 95% CI: 3.0-7.2) of the 429 animals using an in-house ELISA, as well as in 13.9% (10/72) and 66.7% (6/9) of the species and zoos tested, respectively. Serum protein electrophoresis analyses revealed that polyclonal gammopathy was the most common alteration in L. infantum-seropositive individuals. Three animals longitudinally surveyed seroconverted throughout the study period. The multivariate analysis identified the family Canidae as a risk factor for L. infantum exposure.
conclusionsOur results indicate a moderate, widespread and endemic circulation of L. infantum in zoo-kept animals from Spain, which may be of animal health, conservation, and public health concern. Surveillance programs and control measures should be implemented in zoos to minimise the exposure of these species to Leishmania spp., particularly in hotspot areas.
