Coleta de sêmen para inseminação artificial em cães com desvio ventral do pênis / Semen collection for artificial insemination in dogs with ventral deviation of penis

São apresentados dois casos de desvio peniano ventral em cães. No Caso 1, um Poodle de quatro anosde idade com adequada libido, mas incapacidade de cópula devido a desvio ventral do pênis, cuja coleta desêmen foi realizada e inseminadas artificialmente quatro cadelas. No Caso 2, um Dachshund de um ano e meiode idade com adequada libido, mas desvio ventral do pênis, submetido à coleta de sêmen para espermiograma.Este cão foi capaz de copular uma mesma cadela em dois estros distintos. Ao exame radiográfico do cão do Caso2, foi identificada inflexão ventral do osso peniano de 30º, sem sinais agudos ou crônicos de fratura. Em nenhumdos casos havia outras alterações genitais e urinárias concomitantes. Conclui-se pela variável capacidade decópula e possibilidade de coleta de sêmen para inseminação artificial nestes cães.(AU)

Two cases of ventral penile deviation in dogs are presented. In Case 1, a four years old Poodle withadequate libido but disability of copulation because of ventral penile deviation, whose semen collection wassuccessfully achieved and four bitches artificially inseminated. In Case 2, a one and a half years old Dachshundwith adequate libido but ventral penile deviation, who had semen collected for spermogram. This dog was ableto copulate one bitch in two different heats. At the radiographic examination of the Case 2 dog, it was identifieda ventral penile bone inflection of 30º, without acute or chronic signs of fracture. In none of the cases otherconcomitant genital and urinary abnormalities was observed. The results showed the variable copulationcapacity and the possibility of semen collection for artificial insemination of these dogs.(AU)

Chronic pericarditis in a naturally Leishmania (Leishmania) chagasi infected dog

Visceral Leishmaniasis is an infection disease of chronic evolution caused by the protozoan Leishmania sp. The main clinical manifestations in dogs are anemia, progressive weight loss, lymphadenopathy, hepatomegaly, and cutaneous lesions. The heart involvement in visceral leishmaniasis has been rarely reported. The aim of this work was to describe the presence of amastigote forms of Leishmania sp. and associated lesions in the heart of naturally infected dog. For diagnosis analysis, serological tests for anti-Leishmania antibodies and fine-needle aspirative bone marrow cytology were used. The samples (right ventricle and ear skin) were histologically evaluated and processed for imunodetection of Leishmania sp. The most significant histological change was an intense, non-specific, chronic pericarditis associated with intracytoplasmatic amastigotes within macrophages. The tissue parasitism was confirmed through positive imunomarcation. This is a first report of pericardium compromisement of naturally Leishmania infected adult dog.
