RESUMO

Background: The chemodectoma is a rare neoplasm that originates from chemoreceptors located mainly in the aortic body,and carotid body and sinus, and responsible for detecting variations in blood pH, oxygen pressure and carbon dioxide. Dogsof brachiocephalic breeds and aged between 7 and 15 years have greater propensity. A neoplasm involves infiltrative growthin the vessels at the heart base, which leads to Congestive Heart Failure (CHF). The definitive diagnosis is performed byhistopathological and/or immunohistochemical examination. The aim was to report a case of chemiodectoma in a dog,showing the diseases clinical characteristics.Case: A 13-year-old male undefined breed dog was examinated in the medical clinic of small animal of Veterinary Hospital,Federal Rural University of Pernambuco (UFRPE) with respiratory effort, hyporexia, and edema in face, cervical, ventralthorax and thoracic limbs, with thirty days evoluted. About physical examination, we observed cachexia, orthopneic position, cyanosis and edema with a positive Godet sign, as well as 8% dehydration degree. Thoracic auscultation presentedmixed dyspnea and muffled heart sounds. Chest radiography detected an radiopacity increase in pulmonary section andmetastatic neoplastic process associated with pleural and pericardial effusion. Fluid therapy with lactated ringer and posteriorthoracentesis in the right hemithorax region was performed for greater respiratory comfort for the patient. Hematologicalcount and biochemical profiles stated normochromic normocytic anemia, relative and absolute lymphopenia, thrombocytopenia, as well as increased alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The patient diedafter 12 hours when was submitted to necroscopic examination and histopathological evaluation. An infiltrative tumor ofcardiac base was observed invading the light of the right atrium, obstructing the venous return, as well as a large thrombus...(AU)

RESUMO

PURPOSE: Visceral Leishmaniasis (VL) has been considered one of the most important neglected zoonosis in the world. In Brazil, this disease passed for an urbanization process and currently pets (dogs and cats) animals have acquired a great importance on its epidemiology. Studies on dogs have been extensively performed throughout the country, but information about infection in cats has been concentrated in few areas. Therefore, the aim of this study was to investigate the occurrence of infection by Leishmania infantum in domestic cats living in endemic areas for Canine Visceral Leishmaniasis (CVL) in the state of Pernambuco, Northeastern Brazil. METHODS: Domiciled cats (n = 128) were sampled for different biological samples (i.e., blood, conjunctival swab and fine needle aspiration of lymph nodes) that were microscopically and molecularly analyzed through PCR and sequencing. RESULTS: Amastigote forms of Leishmania sp. were detected in a single animal (fine needle aspiration of lymph node). This same animal scored positive at molecular examination (blood and lymph node) and the sequence analysis revealed an identity higher than 99% with L. infantum sequences DNA available in Genbank database. CONCLUSION: This is the first molecular characterization of L. infantum infecting domestic cats in Pernambuco. Therefore, veterinary practitioners should consider this putative infection in cats living in areas where canine and human Leishmaniasis has been reported.

RESUMO

Visando promover aos produtores da região um método alternativo de controle parasitário, o presente trabalho avaliou a eficiência anti-helmíntica do extrato aquoso da semente de mamão Carica papaya, em contraste com o cloridrato de levamisol em 45 ovinos sem padrão de raça definida, do Rio Grande do Norte. Avaliou-se a redução na contagem de ovos por gramas de fezes e redução das larvas de terceiro estágio em três grupos (controle, cloridrato de levamisol e extrato) definidos. Diferenças estatísticas entre e dentro dos grupos foram conduzidas por análise de variância, seguida do teste de Tukey. Os Valores de P<0,05 foram considerados significativos. Quando cada grupo foi comparado ao seu respectivo dia zero, observou-se que o OPG do grupo extrato apresentou uma redução constante e semelhante ao grupo cloridrato de levamisol e a partir do terceiro dia foi superior a este último. Quanto ás larvas, foram identificados Haemonchus sp., Oesophagostomum sp. e Tricostrongylus sp. em todos os grupos. Embora o extrato tenha apresentado uma redução na contagem de ovos, o número de larvas, especificamente as do tipo Haemonchus sp. foi constante. O extrato da semente de mamão utilizado nos ovinos tratados foi eficaz no controle do OPG durante os dias experimentais.(AU)

Aiming to promote local producers an alternative method of parasite control, this study evaluated the efficiency anthelmintic anthelmintic of aqueous extract of Carica papaya seed, in contrast with levamisole hydrochloride in 45 sheep no breed standard of Rio Grande do Norte. We evaluated the reduction in egg count per gram of feces and reduction of third stage larvae in all three groups (control, levamisole hydrochloride and extract) defined. Statistical differences between and within groups were conducted using analysis of variance followed by Tukey's test. Values of P<0.05 were considered significant. When each group was compared to its corresponding zero days, it was observed that OPG extract group showed a reduction constant and similar to the group levamisole hydrochloride and the third day was superior to the latter. Regarding Larvae were identified Haemonchus sp., Oesophagostomum sp. and Tricostrongylus sp. in all groups. Although the extract has shown a reduction in egg counts the number of larvae, particularly those of the type Haemonchus sp. was constant. The papaya seed extract used in treated sheep was effective in controlling OPG during the experimental days.(AU)

RESUMO

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. contortus provenientes 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 µm. 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.

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 µm. 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.
