| ABSTRACT: Canine visceral leishmaniasisis an important disease caused by the protozoon Leishmania infantum which affects several organs and systems, including the genital tract. The L. infantum tropism to the male genital system and correlation among parasite load, immunohistochemistry detection and structural changes in these organs is controversy. Therefore, the aim of this study was to evaluate this correlation in the genital organs of the male dogs naturally infected with L. infantum. Samples from testicles, epididymis, prostate, glans penis, prepuce and scrotum were collected from 19 positive adult dogs. Structural changes were observed in the testicles (5.2%), epididymis (2.6%), prepuce (5.2%) and scrotum (5.2%) of the samples positive at... |

| ABSTRACT: Visceral leishmaniasis (VL) is caused by the protozoon Leishmania infantum . Transmission of this parasite to hosts occurs mainly through the bite of infected sand flies. However, alternative infection routes have been hypothesized, especially in areas where the biological vector is absent. The exact time of infection and whether in utero transmission occurs have still not been fully elucidated. This report demonstrates molecular evidence of vertical transmission of L. infantum from a pregnant dog to the embryo. Samples (e.g. vulva, vagina, cervix, uterine body, uterine horn and ovaries) from a female naturally infected by L. infantum and from her embryo were molecularly analyzed by means of qPCR and cPCR followed by DNA sequencing. The... |

| ABSTRACT: The aim of the present study was to investigate the correlations among chronic inflammatory reaction, immunostaining and parasite load in the genital system of female dogs naturally infected with Leishmania infantum . Animals (n = 10) used in this study were from the Department of Vector Control and Animal Surveillance of the municipality of Caruaru, state of Pernambuco, Brazil. Fragments of the vulva, vagina, cervix, uterine body, uterine horns and ovaries were submitted to histopathological analysis, immunohistochemistry (IHC) and DNA detection of amastigotes by qPCR. Correlations were found between the IHC findings and chronic inflammatory infiltrate related to L. Infantum only in the vulva and vagina; whereas, the same inflammatory reactions... |
