First molecular detection of canine herpesvirus 1 (CaHV-1) in the Eastern Brazilian Amazon.

BACKGROUND: Canine herpesvirus type 1 (CaHV-1) infects dogs and is associated with neonatal deaths and reproductive, ocular, neurological, and respiratory problems. In Brazil, reports of CaHV-1 have been restricted to the southeast and south regions, particularly in municipalities in the state of Rio Grande do Sul. OBJECTIVES: To assess the presence and variability of CaHV-1 in canine populations in the state of Pará, North Brazil. METHODS: Biological samples from 159 dogs from 4 municipalities in the State of Pará were evaluated using polymerase chain reaction and phylogenetic analyses, with the target being the viral enzyme, thymidine kinase. RESULTS: CaHV-1 was detected in 13 dogs (8.2%), with 2 animals being from the municipality of Santa Bárbara do Pará, 8 from Algodoal Island, 2 from Salinópolis, and one from Capanema. The study sequences revealed 100% identity among themselves and 64% to 100% identity with the other nucleotide sequences from Australia, Brazil, United Kingdom, and United States, including 100% identity with the 2002 isolate from Australia. The 1996 isolate from France was grouped in a branch that was different from the sequence of this study. CONCLUSIONS: This study presents the first molecular detection of CaHV-1 in dogs from the Amazon region in northern Brazil. The nucleotide identity between the strains and cytosine insertion in the sequences isolated in this study suggests at least 2 strains of CaHV-1 circulating in Brazil (Pará and BTU-1).

Adenocarcinoma em pavilhão auricular de uma felina / Adenocarcinoma in a feline auricular pavilion

Um felino não definido foi admitido no HOVET / UFRA com desidratação e extenso traumatismo craniano próximo à aurícula esquerda. Foi observada uma massa localizada próxima à base das orelhas. Após verificar que o animal não melhorou a cicatrização, foi escolhida uma técnica de excisão por conchectomia. O material foi enviado para exame histopatológico, que mostrava diagnóstico morfológico de adenocarcinoma de provável origem apócrina grau II / III. A radiação ultravioleta da luz solar é um fator que pode contribuir para a formação de carcinoma espinocelular nas extremidades das orelhas de gatos de vida livre com pelagem leve.(AU)

A no defined bred feline was admitted to the HOVET/UFRA with dehydration and extensive head injury near the left auricle. A mass located near the base of the ears was observed. After verifying that the animal did not improve healing, an excision by conchectomy technique was chosen. The material was sent for histopathological examination, which showed a morphological diagnosis of adenocarcinoma of probable grade II / III apocrine origin. Ultraviolet radiation from sunlight is a fator that can contribute to the formation of squamous cell carcinoma on the ends of the ears of free-living cats with light coat.(AU)
