Atypical transmissible venereal tumor in dogs

Background: The Transmissible Venereal Tumor (TVT), classified as a round cell tumor, is considered one of the oldestexisting tumors. It affects dogs all over the world and has a contagious characteristic. Despite the good response to clinicaltreatment in most cases, it can sometimes have non-classical presentations and even different behavior. Thus, the presentstudy aims to report 3 cases of atypical TVT treated at the Veterinary Medical Teaching Hospital of the State University ofMaringá (UEM) in Umuarama, Paraná, aiming to describe the epidemiology and clinical-pathological aspects, focusingon the diagnostic method used, the treatment of choice and the clinical follow-up of each case.Cases: Case records of 3 intact male mongrel dogs with atypical Transmissible Venereal Tumor (case 1: intranasal; case2: intra-abdominal and case 3: cutaneous with lymph node metastasis) were reviewed regarding history, clinical signs,duration of clinical signs, examination findings, results and findings of complementary exams (hematological, biochemical,radiographic, ultrasonographic and cytological), treatment, follow-up and final result. Case 1: had an ulcerated mass in thenasal plane causing significant airway obstruction and respiratory difficulty. Case 2: had a lesion in a typical location (penilemucosa in the glans area) but with a large intra-abdominal mass in the lumbar paravertebral region, causing compressionof important structures. Case 3: on the other hand, had cutaneous TVT with several ulcerated plaque lesions all over theskin, in addition to popliteal lymph node enlargement due to metastasis later confirmed by microscopy. All dogs reportedwere mixed breed, intact males with free access to the street. Despite...

Criação comercial sustentável de jacaré no Brasil / Sustainable commercial creation of alligator in Brazil

Considerados animais semiaquáticos, os crocodilianos, que hoje fazem parte da fauna brasileira, estão distribuídos em diversas regiões do Brasil, com predominância no Pantanal, na bacia Amazônica e nas bacias dos rios São Francisco e Paraná. Jacaré do pantanal (Caiman yacare), jacaré-tinga (Caiman crocodilus), jacaréde-papo-amarelo (Caiman latirostris), jacaré açu (Melanosuchus niger), jacaré paguá (Paleosuchus palpebrosus) e jacaré coroa (Paleosuchus trigonatus) são as espécies que ocorrem no território nacional, das quais se destacam os exemplares de C. yacare, C. latirostris e o C. crocodilos, uma vez que possuem boas características para produção e são aptas ao sistema de criação em cativeiro no país. Com o aumento da procura de produtos e subprodutos dessas espécies, houve consequente necessidade de regulamentação para sua criação, visto que a exploração desregrada desses indivíduos, bem como a caça ilegal, estavam culminando na redução de seus exemplares, fato este comprovado, já que algumas espécies foram incluídas na lista de animais em extinção (Apêndice I da CITES). Contudo, a criação de legislações que favoreceram a prática da criação sustentável, com destaque para os sistemas Ranching e Farming, bem como o aumento de estudos/conhecimento sobre as espécies, culminaram na diminuição da caça desses animais, contribuindo, dessa maneira, para o restabelecimento das populações de jacarés na fauna nacional e para a manutenção do ecossistema em que elas estão inseridas.

Considered semi-aquatic animals, crocodilians, which are now part of the Brazilian fauna are distributed in several regions of Brazil, predominantly in the Pantanal, in the Amazonia basin and in the basins of the São Francisco and Paraná rivers. The yacaré (Caiman yacare), spectacled caiman (C. crocodilus), broad-snouted caiman (C. latirostris), black caiman (Melanosuchus niger), dwarf caiman (Paleosuchus palpebrosus) and smooth-fronted caiman (P. trigonatus) are the species that occur in the Brazilian territory, of which stand out the specimens of C. yacare, C. latirostris and the C. crocodilos, since they have good characteristics for production and are suitable for the captive breeding system in the country. With the increase in demand for products and byproducts of these species, there was a consequent need for regulation for their breding, since the disorderly exploration of these individuals, as well as illegal hunting, were culminating in the reduction of their numbers, a fact proven since some species had been included in the past in the list of endangered animals (CITES Appendix I). However, the creation of laws that favored the practice of sustainable breeding, with emphasis on the Ranching and Farming systems, as well as the increase in studies / knowledge of the species, culminated in the reduction of hunting of these animals, thus contributing to the reestablishment of alligator populations in the national fauna and for the maintenance of the ecosystem in which they are inserted.
