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 animal’s 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 pig’s ear and in many occasions exhibited ulceration and bleeding. One of the nodules was submitted for histopathology examination. Macroscopically it measured 3 cm in diameter, had an irregular and ulcerated surface, and a wide base. Cut surface had a firm consistency and whitish color. Microscopic examination revealed proliferation of neoplastic epithelial cells arranged in islands and trabeculae, with slightly eosinophilic cytoplasm, pleomorphic, round, reniform nucleus, with loose chromatin and 1-3 nucleolus. Mitotic figures were infrequent. In the central area of the islands, there was individual cell keratinization. There was a moderate, fibrovascular supporting stroma with intense inflammatory infiltrate composed of lymphocytes, plasma cells and eosinophils. Anti-cytokeratin (AE1/AE3) immunohistochemical assay (IHC) revealed a strong diffuse positive staining on the cytoplasm of tumoral epithelial cells, and anti-vimentin IHC showed positive staining on the supporting tissue cells (fibroblasts and endothelial cells).Discussion: The diagnosis of squamous cell carcinoma in this pig was based on clinical and pathological findings since it was observed proliferation of neoplastic epithelial cells often forming “keratin pearls” and immunohistochemistry positive for cytokeratin was immunostaining in the cytoplasm of tumor cells. Information on the occurrence of SCC in pigs is scarce in the literature, especially in Brazil. In a survey of neoplasms in farm animals in Southern Rio Grande do Sul with cases from 1978 to 2002, neoplasms in pigs represented 0.6% of the diagnoses when compared to the number of neoplasms in cattle and horses. The low number of cases in this species is due to the fact that a large proportion of the population is slaughtered at a young age and therefore the chances to develop neoplasms are lower. The main SCC growth sites include areas deprived of hair, especially in animals with unpigmented skin. In the pig described here, the neoplasm was located on the outer surface of the ear, which was exposed to ultraviolet rays. Granuloma, papilloma, and basal cell tumor should be considered in the list of differential diagnosis when SCC is suspected. Neoplasms in pigs are scarcely reported.Keywords: neoplasm, carcinoma, pig, immunohistochemical.

Resumo: No período de janeiro de 2011 a dezembro de 2014 foram diagnosticados 9 surtos (A, B, C, D, E, F, G, H e I) de Oestrus ovis em pequenos ruminantes no estado da Bahia. No surto A obteve-se 0,5% (1/200); B 2,2% (2/90); C 0,8% (1/120); D 2% (2/100); E 1% (1/100); F 3% (1/33); G 0,6% (1/150); H 2,5% (5/200); I com 11,4% (8/70) em ovinos e 5% (2/40) em caprinos. Os sinais clínicos associados ao parasitismo pelas larvas nos surtos foram respiração ruidosa, espirro seguido de secreção nasal catarral, inquietação, movimentação excessiva da cabeça e andar em círculo. Macroscopicamente havia nos seios e conchas nasais hiperemia, edema da mucosa e presença de larvas. Todas as larvas coletadas dos cornetos e conchas nasais variavam desde o primeiro ao terceiro estágio de desenvolvimento. Algumas larvas L3 coletadas nas necropsias foram incubadas e o imago obtido das pupas mediram aproximadamente 10mm de cor acinzentada e abdômen escurecido. Realizada análise descritiva das condições climáticas, ano e positividade de casos de oestrose, demonstrou que a ocorrência tem tendência de crescimento com os anos (p˂0,001) e que houve casos com menor média de temperatura mínima (p˂0,001), possibilitando o desenvolvimento da mosca de O. ovis, demonstrando que houve a introdução da mosca enTtre o rebanho de ovinos e caprinos do estado da Bahia, e que as condições climáticas são ideais para perpetuação da espécie.

In order to determine the main anatomopathological findings of Testudines necropsied in the Distrito Federal, all necropsy records performed at the “Laboratório de Patologia Veterinária” of the “Universidade de Brasília” (LPV-UnB) on Testudines during the period from January 2008 to July 2020 were reviewed. The 72 cases reviewed were grouped and classified according to species, sex, origin, season of occurrence, and diagnosis. In 69.44% of the cases the species was informed in the necropsy protocols, which included Phrynops geoffroanus (38%), Trachemys dorbigni (36%), Chelonoidis carbonaria (14%), Chelonoidis denticulata (10%) and Podocnemis expansa (2%). In 30.55% of the cases this parameter was not informed and were classified only as Testudines. In 41.66% of the cases the sex was informed, being female 22.22%, male 19.44%, and 58.33% were not informed. Of these animals 79.16% were from environmental agencies and 20.84% from zoos and/or guardians. In 70.83% of the animals analyzed they were directly related to the autumn and winter seasons, with June being the most frequent month (29.17%). The conclusive diagnosis was possible in 68.05% of the cases. The category of disorders caused by injurious agents (48.97%) was the most prevalent, followed by inflammatory disorders (32.65%) and nutritional and metabolic disorders (28.57%). The main diagnoses were carapace and/or plastron fracture with 30.61%, hepatic steatosis (20.40%) and pneumonia (10.22%). Most cases of carapace or plastron fracture and hepatic steatosis occurred in animals from environmental agencies.

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.

RESUMO.-Descreve-se um surto de intoxicação por Metternichia princeps em caprinos no Estado da Bahia. De oito caprinos, três morreram, dos quais dois foram necropsiados; cinco não adoeceram. Os principais sinais clínicos caracterizaram-se por secreção nasal mucosa, emagrecimento, diarreia, apatia, debilidade leve, andar cambaleante, flexão dos membros torácicos e pélvicos, decúbito esterno-abdominal e decúbito lateral, seguidos de morte após aproximadamente dois dias de evolução clínica. Na necropsia foi observado edema pulmonar, hidrotórax, hidropericárdio, ascite, rins pálidos, edema perirrenal e hemorragias no tecido subcutâneo. Microscopicamente nos rins havia acentuada necrose de coagulação do epitélio tubular e túbulos com regeneração do epitélio. No pulmão havia acentuada congestão associada a edema interalveolar e interseptal. Na bioquímica sanguínea observou-se aumento na ureia, creatinina e creatinina fosfoquinase.TERMOS DE INDEXAÇÃO: Plantas tóxicas, Metternichia princep, Solanaceae, nefrose, edema pulmonar, ruminante, intoxicação por plantas. INTRODUÇÃOMetternichia princeps, árvore da família Solanaceae, é popularmente conhecida como "trombeteira", "café-do-mato" e "jasmim-do-morro" (Lorenzi 2009. Casos de intoxicação espontânea só foram registrados em caprinos no Estado do Rio de Janeiro (Caldas et al. 2011). Experimentalmente a intoxicação foi reproduzida em caprinos, bovinos, ovinos e coelhos , Maran et al. 2012 Out of eight goats three showed symptoms of poisoning and died; on two of them post-mortem examinations were performed. The main clinical signs were nasal mucous secretion, weight loss, diarrhea, lethargy, mild weakness, staggering gait, flexion of the fore and hind limbs, sternal recumbence, and lateral recumbence followed by death after approximately two days of clinical manifestations. The serum concentration of urea and creatinine and the serum activities of creatine phosphokinase were increased. At necropsy pulmonary edema, hydrothorax, hydropericardium, ascites, pale kidneys, perirenal edema and hemorrhages in the subcutaneous tissue were observed. Microscopically the kidneys showed accentuated coagulation necrosis of the tubular epithelium and tubules and epithelial regeneration. In the lungs there was accentuated congestion associated with interalveolar and interseptal edema.
