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: 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...

Patologias genitais associadas à leishmaniose visceral canina
Provedor de dados: 65
Autores: Oliveira,Vinícius Vasconcelos Gomes de; Alves,Leucio Câmara; SilvaJunior,Valdemiro Amaro da.
A leishmaniose visceral canina (LVC) é uma doença parasitária crônica causada por protozoários pertencentes ao gênero Leishmania. No Brasil, a transmissão se dá, principalmente, pela ação hematófaga de insetos vetores pertencentes à subfamília Phlebotominae, particularmente, a espécie Lutzomyia longipalpis. Todavia, a trasmissão vertical e venérea da LVC está presente. Os principais sinais clínicos observados nos animais acometidos pela LVC são linfoadenomegalia, dermatopatias, hepatoesplenomegalia, onicogrifose e oftalmopatias, contudo quadros atípicos podem ser observados, inclusive com o envolvimento do sistema genital. Dessa forma, o objetivo deste artigo é realizar revisão sobre as principais patologias genitais em cães machos e fêmeas com...

Molecular evidence of early vertical transmission of Leishmania ( Leishmania ) infantum in a dog

Autores: Oliveira,Vinícius Vasconcelos Gomes de; Ramos,Rafael Antonio Nascimento; Ramos,Carlos Alberto do Nascimento; Guerra,Neurisvan Ramos; Maia,Frederico Celso Lyra; Alves,Leucio Câmara; Silva Junior,Valdemiro Amaro da.
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...

Transmission routes of visceral leishmaniasis in mammals
Provedor de dados: 65
Autores: Oliveira,Vinícius Vasconcelos Gomes de; Alves,Leucio Câmara; Silva Junior,Valdemiro Amaro da.
Visceral leishmaniasis (VL) is a chronic disease caused by Leishmania infantum. The major sites of parasite localization in infected animals are the secondary lymphoid organs, bone marrow and cutaneous tissue. However, reports exist on the detection of the parasite in the organs of the male and female genital system. The main route of transmission is related to the hematophagous sandfly vectors of the genus Lutzomyia(New World) and Phlebotomus(Old World). However, other routes of transmission may be mentioned, such as sexual, vertical, hematogenic without vector and others involved in VL epidemiology. Thus, the current article reviews the main forms of transmission of visceral leishmaniasis in mammals
