Occurrence and Molecular Identification of Hemoparasites in Wild Mammals Kept in Rehabilitation Centers in Brazil.
Article in Acta parasitologica, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
purposeHepatozoonosis and piroplasmosis are diseases caused by apicomplexan protozoa that affect different types of animals, including mammals. The present study aimed to evaluate the occurrence of Hepatozoon spp. and piroplasms in wild mammals kept in captivity in rehabilitation centers in the states of Minas Gerais and Goiás, Brazil.
methodsFor this, blood samples from 152 animals were collected and analyzed by conventional optical microscopy and polymerase chain reaction (PCR). In addition, positive PCR samples were submitted to sequencing for molecular characterization of the specimens found.
resultsMicroscopic analysis revealed 53 of the 152 animals (28.3%) parasitized by piroplasms. No Hepatozoon sp. was observed. On the other hand, using the primers HepF300/HepR900 and Piro1F/Piro5R, both amplifying fragments of the 18S rDNA gene, eight animals (5.2%) were positive for Hepatozoon spp. and 40 (26.3%) for piroplasms. From the sequencing of the positive samples Hepatozoon canis, Hepatozoon felis, Theileria cervi, Theileria equi and Cytauxzoon felis were identified. In addition to the aforementioned hemoparasites, some animals were found parasitized by microfilaria. Such data ratify the presence of hemoparasites in captive wild animals, and are unprecedented in the two geographical regions covered by the present study. 19.7% of mammals harbored ectoparasites of the genera Amblyomma and Rhipicephalus.
conclusionWild mammals are infected by several pathogens that can also infect domestic animals, some of them potentially zoonotic which can directly contribute to mortality and species reduction. Therefore, a deep understanding of the parasites, the hosts and the diseases is extremely necessary so that prevention, control and treatment measures are effectively applied.
