Plain-English summary
A group of 34 dogs diagnosed with canine visceral leishmaniasis (CVL) was tested for the presence of Leishmania parasites in their reproductive systems. The results showed that 79% of the dogs had these parasites in their reproductive tissues, suggesting that the disease could be spread in ways other than just through sand fly bites. This finding highlights the importance of considering different transmission routes when dealing with CVL.

Abstract
BACKGROUND: Although canine visceral leishmaniasis (CVL) transmission primarily occurs through the bite of phlebotomine sand flies infected with Leishmania infantum, alternative routes may exist. METHODS: Thirty-four dogs diagnosed with CVL were sampled for parasitological investigation in tissues from the reproductive tract. RESULTS: Amastigotes of Leishmania sp. were present in 79% (27/34) of the reproductive system samples, with distinct infection rates depending on the tissue. CONCLUSIONS: Our data confirms that alternative routes, such as horizontal and vertical transmissions, should be considered in the epidemiological chain of CVL.
