Dogs may carry Leishmania tropica and Leishmania major in their blood circulation: a molecular and hematological study.
Article in BMC veterinary research, 2024. 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
backgroundDogs may be infected with species of Leishmania parasites that are disseminated through blood circulation and invade the internal organs. In this study, we aim to detect the parasite in the blood of dogs using the PCR technique. The present work was performed from February 2022 to May 2023 in Fars Province, southern Iran, where the disease is endemic.
resultsIn total, 7(5.1%) out of 135 blood samples, six were identified as Leishmania tropica and one as Leishmania major. We found no trace of Leishmania infantum, which is always known for visceral infection. In addition, no sign of cutaneous lesions or a significant disease was seen in the animals infected with both species. Of 48 dogs with anemia, two were Leishmania positive. The mean value of hematological parameters in the infected dogs was within the normal range except for a significant reduction in the platelet measures (p < 0.05).
conclusionsOur data revealed that both Leishmania species, tropica and major, may manifest as viscerotropic leishmaniasis. More investigations are needed to understand the conditions under which these species choose the type of infection. Moreover, our data emphasize the role of asymptomatic dogs in carrying these parasites, a crucial factor in spreading the disease.
