Survey of avifauna housed in the wild animal triage centers in the state of Bahia, period 2009 to 2019, emphasizing trafficking / Levantamento de avifauna alojada nos Centros de Triagem de Animais Silvestres no estado da Bahia, período 2009 a 2019, com ênfase no tráfico

Brazil is one of the primary suppliers of wildlife for trafficking, which constitutes a significant threat to biodiversity, which can cause the extinction of species, especially birds, the most important victims of trafficking. This study analyzed the wild avifauna collected in the Triage Centers of Wild Animals (CETAS) of Bahia, to inventory the most apprehended species that are threatened with extinction, and estimate the municipalities that function as suppliers and traders of wildlife. Data from 2009 to 2019 were made available by the Salvador and Vitoria da Conquista units, and that from 2010 to 2016 was made available by the, Porto Seguro unit. The survey was conducted through the entry records of birds, considering apprehension, spontaneous deliveries, rescues, and transfers between units involved in the study. Out of the total 80,948 birds analyzed, 65,315 (80.68%) were apprehended; 7,885 (9.74%) were voluntary deliveries; 6,196 (7.65%) were rescues, and 1,034 (1.28%) were transfers. There was no entry modality for 518 (0.64%) specimens. The most trafficked species were Sicalis flaveola (Saffron Finch), Sporophila nigricollis (Yellow-bellied Seedeater), Paroaria dominicana (Red-cowlead Cardinal), Cyanoloxia brissonii (Ultramarine Grosbeak), Sporophila caerulescens (Double-collared Seedeater), and Sporophila albogularis (White-throated Seedeater). Nine hundred twenty six specimens exhibited some threat. Analysis showed that the greatest flow of bird traffic occurs on BR 242 and BR 116. The municipalities that comprise the mesoregions Center-South, Center-North Baiano, and the Metropolitan Region of Salvador are those with greater concentrations of illegal activity. Irecê and Paulo Afonso constitute areas for the capture and commercialization of wild animals.

O Brasil é um dos principais fornecedores de vida silvestre para o tráfico. Essa prática configura ameaça à biodiversidade brasileira, provoca extinção de espécies, sobretudo da avifauna, as principais vítimas do tráfico. O estudo objetivou analisar a avifauna silvestre recolhida nos Centros de Triagem de Animais Silvestres (CETAS) do estado da Bahia, buscando quantificar as espécies mais apreendidas, ameaçadas de extinção e estimar os municípios que atuam como possíveis fornecedores e comercializadores de vida silvestre. Os dados disponibilizados pelas unidades de Salvador e Vitória da Conquista compreenderam o período de 2009 a 2019 e unidade de Porto Seguro, o período de 2010 a 2016. O levantamento foi realizado através dos registros de entrada de aves, considerando apreensões, entregas espontâneas, resgates e transferências entre unidades envolvidas no estudo. Foram recebidas 80.948 aves, sendo procedentes de apreensões 65.315 (80,68%); entregas voluntárias 7.885 (9,74%); resgates 6.196 (7,65%) e transferências 1.034 (1,28%). Não houve registro de modalidade de entrada para 518 (0,64%) espécimes. As espécies mais traficadas foram Sicalis flaveola (Canário-da-terra), Sporophila nigricollis (Papa-capim), Paroaria dominicana (Cardeal-do-nordeste), Cyanoloxia brissonii (Azulão), Sporophila caerulescens (Coleirinho) e Sporophila albogularis (Golinho). Identificou-se 926 espécimes com algum tipo de ameaça. A análise demonstrou que o maior fluxo de tráfico de aves ocorre nas BR 242 e BR 116. Os municípios que compõem as mesorregiões Centro-Sul, Centro Norte Baiano e a Região Metropolitana de Salvador são os que possuem maiores fluxos de atuação no comércio ilegal. Irecê e Paulo Afonso são áreas de captura e comercialização intensa de animais silvestres.

Squamous cell carcinoma in a pig / Carcinoma de células escamosas em suíno

Background: Squamous cell carcinoma (SCC) is a malignant neoplasm of epidermal cells that exhibits keratinocyte differentiation. These neoplasms are common in dogs, cats, horses, and cattle, relatively uncommon in sheep, and rarely affect goats and pigs. There are several factors that are associated with the development of SCC, including prolonged exposure to ultraviolet light, lack of pigment in the epidermis, and sparse coating or lack of fur at the affected sites. The aim of this study was to report the occurrence of squamous cell carcinoma in a domestic pig. Case: A surgically removed nodule from the left ear of a female, light-colored, three-year-old pig, which breed was not defined, was submitted for histopathological analysis. The sample was fixed in 10% formalin, analyzed macroscopically, routinely processed for histology, sectioned at five microns and stained with hematoxylin and eosin. Additionally, anticytokeratin (AE1/AE3) and anti-vimentin immunohistochemical assays were performed. All additional information was provided by the animals owner. According to the history obtained, the animal belonged to a herd made up of five females and one boar. For four months, multiple nodules started to grow on the outer surface of the pigs ear and in many occasions exhibited ulceration and bleeding. One of the nodules was submitted for histopathology examination.[...]
