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.
背景
虽然犬内脏利什曼病（CVL）的传播主要通过感染利什曼原虫的白蛉沙蝇叮咬来实现，但可能存在其他途径。
方法
对 34 只被诊断患有 CVL 的犬进行了寄生虫学检查，采集了生殖系统组织样本。
结果
利什曼原虫的无鞭毛体在 79%（27/34）的生殖系统样本中存在，不同组织的感染率存在明显差异。
结论
我们的数据证实，在 CVL 的流行病学链中，应考虑其他途径，如水平和垂直传播。
