Aplasia uterina total em cadela com atrofia segmentar de vagina / Total uterine aplasia in bitch with segmental atrophy of vagina

Background: Congenital uterine malformations are rarely identified in domestic and human animals and are related to problems during the embryonic formation of the paramesonephric ducts. Cases of agenesis and segmental aplasia or unicorn uterus have been described in bitches, but there are no reports of total uterine aplasia in this specie. The report of a case of total uterine aplasia and segmental atrophy of the cranial vagina, accidentally diagnosed is reported herein.Case: An adult female bitch without defined breed in bad general condition was attended in the emergency service in a Veterinary Hospital. During anamnesis the information was restricted because it was an errant animal rescued for the consultation, but accompanied for at least 12 months in the environment in which it lived. Data related to the estrous cycle were unknown, but no gestation was observed in the last year. Investigations detected anemia and intense thrombocytopenia, azotemia and increased alanine aminotransferase. Two days later, with no progression, images suggestive of hemometra/ mucometra were observed during abdominal ultrasonography, and the patient underwent emergency ovariohysterectomy despite the general poor condition. Before the procedure the uterus was not routinely identified, but a fibromuscular, nontubular and thin structure occupied the region corresponding to the horns and uterine body, thickening in the cervix region. Death four days after surgery and sent to necropsy. During necropsy it was observed that the vulva and the vestibule of the vagina did not present macroscopic alterations, however there was a marked digitiform narrowing of the cranial region of the vagina, which ended in blind bottom. The mucosa in this narrowing was smooth, without folds. The microscopic structure of the ovaries, uterine tubes and caudal vagina were preserved.[...]

Detecção de DNA de Brucella spp. em amostras de sangue e de suabe vaginal ou prepucial de cães do município de Natal, Rio Grande do Norte, Brasil / Detection of Brucella spp. DNA in samples of blood and vaginal or preputial swab from dogs in the county of Natal, Rio Grande do Norte, Brazil

Objetivou-se com este trabalho detectar o DNA de Brucella spp. em amostras de sangue e de suabe vaginal ou prepucial de 80 cães sorologicamente positivos para brucelose pela prova de imunodifusão em gel de ágar (IDGA), no município de Natal, estado do Rio Grande do Norte, Brasil. Amostras de sangue total foram colhidas com anticoagulante (citrato de sódio) juntamente com amostras de suabe vaginal e prepucial , para extração de DNA e posterior realização da rea- ção em cadeia da polimerase (PCR) empregando-se os primers ITS66 e ITS279. O DNA de Brucella spp. foi amplificado em seis animais, sendo um animal em ambas as amostras, dois cães em amostras de sangue e três em amostras de suabe do trato reprodutivo. Concluiu-se que a infecção por Brucella spp. está presente em cães no município de Natal, e que a detecção de DNA do agente em amostras de suabe do trato reprodutivo podem ser utilizadas como ferramenta suple- mentar no diagnóstico de brucelose canina.(AU)

The aim of this work was to detect Brucella spp. DNA in samples of blood and vaginal or preputial swabs in 80 sero-positive dogs for brucellosis by agar gel immunodiffusion test (AGID) from the county of Natal, Rio Grande do Norte State, Brazil. Whole blood samples were collected with anticoagulant (sodium citrate) and vaginal and preputial swab samples for DNA extraction and polymerase chain reaction (PCR) employing ITS66 and ITS279 primers. Six animals showed amplification of Brucella spp., being one animal in both samples, two dogs only in blood samples, and three only in reproductive tract swabs. It is concluded that infection due to Brucella spp. occurs in dogs from the county of Natal, and the detection of DNA of the agent in reproductive tract swabs may be used as complementary tool in the diagnosis of canine brucellosis.(AU)
