Uveitis associated to the infection by Leishmania chagasi in dog from the Olinda city, Pernambuco, Brazil Ciência Rural
Brito,Fábio Luiz da Cunha; Alves,Leucio Câmara; Duque Ortiz,Juan Pablo; Maia,Federico Celso Lyra; Silva Junior,Valdemiro Amaro da; Laus,Jose Luiz.
Among the parasitic diseases, Canine Visceral Leishmaniasis (CVL) is included in the systemic illnesses of chronic evolution that attack men and dogs, presenting varied clinical manifestations as cachexia, dermatologic lesions, peripheral lymphadenopathies, besides the ocular lesions. This work report the case of a dog clinically suspected of having CVL, presenting skin lesions, cachexia, gryphosis, and ocular signs of uveitis. The parasitological diagnosis was accomplished for Canine Leishmaniasis through the visualization of amastigote forms of Leishmania chagasi in smears of bone marrow fluid aspirate, of non-lesioned, and lesioned skin. Alterations in the ocular structures are characterized mainly by mononuclear-plasmocitic infiltrate.

The aim of the present study was to test the hypothesis that the application of fluoxetine ­ a highly selective serotonin reuptake inhibitor (SSRI) ­ in rats during the suckling period induces changes in testicular development. Groups of newborn male rats were randomly assigned with different doses of fluoxetine 24 hours after birth. Each litter stayed with its respective mother during 21 days. Body weight (BW) was measured daily from the 1st -21st day to calculate daily doses of fluoxetine. 5 mg (T1), 10 mg (T2) 20 mg (T3) or deionized water, were injected intraperitoneally. On the 21st day, animals were heparinized, anesthetized and blood was collected by cardiac puncture to determine by radioimmunoassay the follicle stimulating hormone (FSH) levels....

Transmission routes of visceral leishmaniasis in mammals Ciência Rural
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

Histopathological evaluation and parasite quantification (qPCR) in the male dog's genital system after natural infection with Leishmania infantum Ciência Rural
Oliveira,Vinícius Vasconcelos Gomes de; Macedo,Simone Regina Barros de; Araújo,Flábio Ribeiro de; Ramos,Carlos Alberto do Nascimento; Ramos,Rafael Antonio Nascimento; Maia,Frederico Celso Lyra; Alves,Leucio Câmara; Silva Junior,Valdemiro Amaro da.
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...

Correlation between chronic inflammation, immunostaining and parasite load in the genital system of female dogs naturally infected with Leishmania infantum Ciência Rural
Oliveira,Vinícius Vasconcelos Gomes de; Macedo,Simone Regina Barros de; Araújo,Flábio Ribeiro de; Ramos,Carlos Alberto do Nascimento; Ramos,Rafael Antonio Nascimento; Maia,Frederico Celso Lyra; Alves,Leucio Câmara; Silva Junior,Valdemiro Amaro da.
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...

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