RESUMO
Background: Transmissible venereal tumor (TVT) is a neoplasm which primarily affects the genital mucosa of canines. However, this tumor has been described in several extragenital areas. Although there are no major diffi culties to confirm a TVT when present in the genitalia, it can be confused with several conditions, either neoplastic or non-neoplastic, when located beyond the external reproductive organs. The involvement of multiple extragenital locations is poorly reported, which may compromise the tissues involved and hinder the establishment of a diagnostic conclusion. The study aimed to describe a case of multiple and extragenital TVT in dogs.Case: A two year old mongrel dog had a history of swollen nose and ocular abnormalities. The patient underwent physical examination followed by request of nose and eye cytology. The animal was euthanized and sent for autopsy; the material was intended for cytological diagnosis. It was found an increase in volume in the middle third of the nasal region. In the oral cavity, there was a tumor in the caudal third of the hard palate. Neoformations were also detected in the third eyelid. The nasal and eyelid cytological examination was compatible with TVT plasmacytoid pattern. During the necropsy, it was also detected tumors in the nasal cavity, occupying the space of turbinal bones Proliferation occurred even in the palatine bone and phar

RESUMO
In northeastern Brazil, Haemonchus contortus is considered a gastrointestinal nematode with great veterinary relevance, causing reduced production, delayed development, economic losses and death of small ruminants. The objective of this study was to identify the morphometric variation and the types of vulvar appendages in H. contortus from goats in the semiarid region of Rio Grande do Norte. We used 100 units of H. contortus, from the collection of the Laboratory of Animal Parasitology of Federal Rural University of the Semi-Arid (UFERSA), where they were mounted between slide and coverslip with glycerin, to measure in micrometer ocular at 10X objective with correction factor of 1.3636. The body length of males was lower than females (p 0.05), which showed, respectively, mean ± standard deviation of 13,26 ± 1,15 e 18,32 ± 1,39 m. Regarding the type of vulvar appendage found in females, 72% were linguiforme type, 18% flat type and 10% button. These data contribute significantly to the taxonomy and differentiation of these endoparasites, especially in northeastern semi-arid region, where haemonchose has a worrisome role for raising goats.
No nordeste brasileiro, Haemonchus contortus é considerado um nematódeo gastrintestinal de grande relevância médico-veterinária, por causar queda de produção, atraso no desenvolvimento, perdas econômicas e mortes de pequenos ruminantes. O objetivo do presente trabalho foi identificar as variações morfométricas e os tipos de apêndices vulvares existentes em H. contortusprovenientes de caprinos da região semiárida do Rio Grande do Norte. Utilizaram-se 100 exemplares de H. contortus, oriundos do acervo do Laboratório de Parasitologia Animal da Universidade Federal Rural do Semiárido (UFERSA), onde eles foram montados entre lâmina e lamínula com glicerina, para mensuração em ocular micrométrica em objetiva de 10X, com fator de correção de 1,3636. O comprimento corporal dos machos foi inferior ao das fêmeas (p 0,05), os quais apresentaram respectivamente médias ± desvio padrão de 13,26 ± 1,15 e 18,32 ± 1,39 m. Quanto ao tipo de apêndice vulvar encontrado nas fêmeas, 72% foram do tipo linguiforme, 18% do tipo liso e 10% do tipo botão. Esses dados contribuem de forma significativa para a taxonomia e diferenciação desses endoparasitas, principalmente na região do semiárido do Nordeste, onde a haemonchose tem papel preocupante para a caprinocultura.

RESUMO
The moon-fish (Mola mola) is the largest bony fish in the world, mainly inhabiting tropical and subtropical waters of the Atlantic, Indian and Pacific oceans. This fish is characterized by carrying numerous species of parasites, distributed in its different organs. Therefore, this study aimed to report the metazoan parasites in a moon-fish (M. mola) which was found in death in the coastal city of Areia Branca, Rio Grande do Norte, Brazil. The animal, a young male with 24 Kg, was sent to the Laboratory of Animal Pathology of the University of the Semi-Arid (UFERSA) where necropsy was performed. Due to the alterations found, it was necessary to send samples to the Laboratory of Animal Parasitology of UFERSA. Many parasites were detected in the oral cavity, stomach, duodenum, large intestine, liver, muscle and heart. The parasites were identified as belonging to two taxonomic groups of metazoan: digenetic hemiuridae (compatible with trematode Lecithochirium sp.), and plerocercoids from the order Trypanorhyncha (immature forms of a cestoda pseudophyllidea). The identification of parasites found was of vital importance, since it could estimate the infection by endoparasite communities in marine fish inhabiting the Neotropical region in question. Keywords: Parasites, trematode, cestode, Mola mola, Brazil.
O peixe-lua (Mola mola) é o maior peixe ósseo do mundo, habitando principalmente águas tropicais e subtropicais dos oceanos Atlântico, Índico e Pacífico. Este peixe destaca-se por transportar inúmeras espécies de parasitos, distribuídos em diferentes órgãos. Logo, o presente trabalho objetivou relatar o parasitismo por metazoários em um exemplar de peixe-lua (M. mola) que foi encontrado em óbito no litoral da cidade de Areia Branca, Rio Grande do Norte, Brasil. O animal, um espécime macho, jovem, com 24 Kg, foi encaminhado para o Laboratório de Patologia Animal da Universidade Federal Rural do Semi-Árido (UFERSA) onde foi submetido a necropsia. Em virtude das alterações encontradas, tornou-se necessário o envio de amostras para o Laboratório de Parasitologia Animal da UFERSA. Constataram-se inúmeros parasitos na cavidade oral, estômago, duodeno, intestino grosso, fígado, músculo e coração. Os parasitos foram identificados como pertencentes a dois grupos taxonômicos de metazoários: digenéticos hemiurídeos (compatíveis com o trematódeo Lecithochirium sp.) e plerocercóides da ordem Trypanorhyncha (formas imaturas de um cestódeo pseudofilídeo). A identificação dos parasitos encontrados foi de extrema importância, uma vez que possibilitaria estimar a infecção por comunidades de endoparasitos nos peixes marinhos neotropicais que habitam a região em questão.

RESUMO
The gastrointestinal parasites control in goats and sheep flock have been accomplished through several chemical groups of anthelmintics, without considering the predominant epidemic factors of the local and the accomplishment of rational outlines of drugs alternation. The objective of present work was to evaluate the sensibility of the gastrointestinal nematodes in relationship to the anthelminthics within state of Rio Grande do Norte. Therefore, it has been used 54 goats and 54 sheep, females without pattern racial defined. The composts tested were albendazole 10% and ivermectin. For the evaluation of the resistance reduction test it was used the number of eggs per gram of feces (RCOF) and fecal culture. In sheep RCFO was: for albendazole 44,3%, 54,2% and 70,9%, for ivermectin 11,4%, 28,8% and 22,1% at the 7th, 14th and 21st day powder-treatment respectively. In goats RCOF was: for albendazole 2,9%, 9,6% and 24,1%, and for ivermectin 24,9%, 12% and 5,9% at the 7th, 14th and 21st day powder-treatment respectively. Thus, it was observed that the gender Haemonchus was prevalent in the resistant population for the anthelmintics tested in sheep as in goats, followed by Strongyloides, Trichostrongylus, and Oesophagostomum. Keywords: albendazole, ivermectin, goats, sheep.
O controle dos endoparasitos gastrintestinais em rebanhos de caprinos e ovinos vem sendo realizado através de diversos grupos químicos de anti-helmínticos, sem considerar os fatores epidemiológicos predominantes da região e a realização de esquemas racionais de alternância de drogas. O objetivo do presente trabalho foi avaliar a sensibilidade dos nematóides gastrintestinais a compostos anti-helmínticos no estado do Rio Grande do Norte. Foram utilizados 54 caprinos e 54 ovinos, fêmeas sem padrão racial definidos. Os compostos testados foram albendazol 10% e ivermectina. Para a avaliação da resistência usou-se o teste de redução na contagem de ovos por grama de fezes (RCOF) e coprocultura. Em ovino a RCFO foi albendazole 44,3%, 54,2% e 70,9%, ivermectina 11,4%, 28,8% e 22,1% em 7, 14 e 21 dias respectivamente. Em caprinos a RCOF foi: para albendazole 2,9%, 9,6% e 24,1%, e para ivermectina 24,9%, 12% e 5,9% em 7, 14 e 21 dias respectivamente. Observou-se que o gênero Haemonchus, foi o mais prevalente na população resistente aos anti-helminticos testados, tanto em ovinos como em caprinos, seguidos de Strongyloides, Trichostrongylus, e Ooesophagostomum.
