Cryptosporidium spp. oocysts and Giardia spp. cysts in coatis (Nasua nasua L. 1766) from Pará, Brazil

Zoonotic enteroparasitosis represent an important public health problem, and species of protozoa such as Cryptosporidium spp. and Giardia spp. can reach high frequencies in regions where basic sanitation conditions are poor, which promotes outbreaks of diarrhea in humans and domestic and wild animals. Wild mammals such as the South American coati (Nasua nasua) feed on insects present in the soil, fruits, and small vertebrates, and are susceptible to contamination by enteroparasites present in the environmental niche. The aim of the present study was to investigate the occurrence of Cryptosporidium spp. and Giardia spp. in N. nasua from a region in the Brazilian Amazon. Fecal samples of 27 coatis two from free-living and 25 from captivity were collected in three different municipalities in the state of Pará, Brazil. The search for Giardia spp. and Cryptosporidium spp. in the collected samples were performed using the direct and Kinyoun methods, respectively, and a commercial immunological test (RIDA®QUICK Cryptosporidium/Giardia Combi. ®R-Biopharm) was used to detect antigens from both parasites. Cryptosporidium spp. oocysts were found in 11.1% (3/27) of the samples; one from a free-living animal and two from captive animals. Giardia spp. cysts were found in 11.1% (3/27) of the samples, all from captive animals. This is the first report of infection by these protozoans in this c

Bone Radiographic Changes in Slaughter Buffalos with Low Body Condition Index

Background: The largest buffalo herd in Brazil is located on the Island of Marajó, in the State of Pará, northern Brazil. The pastures of the Island of Marajó consist of low quality graminaceous plants, which are generally poor in protein and mineral content. Unbalanced diets associated with low quality pastures are responsible for latent, sub-clinical diseases and metabolic disorders in bovines which affect bone health, especially in periods such as pregnancy and lactation. The purpose of this study was to point out and to describe the radiographic bone changes of buffalos with low body index bred in extensive system and intended for slaughter on the Island of Marajó, Brazil.Materials, Methods & Results: Radiographic examinations of anatomical pieces were obtained from 34 animals of buffalo species, with no distinction of gender, age, or breed. The animals were selected among those that were in the stockyard waiting for slaughtering for the obtainment of the anatomical pieces. For this selection, low physical condition was considered, which mainly included individuals with body condition indexes (ICC) of 1 and 2, on a scale of 1 to 5. From this selection, 98 anatomical pieces were obtained, which included: 28 sets of ribs, 20 femurs, 26 metacarpus, 7 mandibles, 3 radius and ulnas, 4 sets of vertebrae, 4 sets of metacarpus and phalanges, 1 tarsus and 1 set of tarsus and met

OCORRÊNCIA E ASPECTOS MACRO E MICROSCÓPICOS DA MUCOMETRA EM CADELAS

A mucometra é uma alteração não inflamatória que afeta o útero por meio do acúmulo de fluído estéril no lúmen uterino. O presente trabalho objetivou relatar a ocorrência de mucometra em cadelas, bem como descrever seus aspectos macroscópicos e microscópicos. Foram utilizados 100 úteros de cadelas procedentes de ovariosalpingohisterectomia de conveniência. As peças foram fixadas inteiras em formaldeído a 10% tamponado por 48 horas. Posteriomente, foram selecionadas amostras de 3 a 5 mm de espessura dos cornos uterinos, seguindo-se ao processamento histológico de rotina, com as lâminas coradas pela Hematoxilina e Eosina. Os animais de estudo foram classificados segundo a faixa etária, o número de partos e o uso de contraceptivos. Os dados obtidos foram tabulados e analisados estatisticamente por meio de análise descritiva e teste Qui-quadrado, utilizando o nível de significância de 5%. Dos úteros analisados 9% (9/100) apresentaram mucometra. As cadelas acima de seis meses e menor ou igual a três anos (66,67%), nulíparas (88,89%) e que fizeram uso de contraceptivos (66,67%) foram mais acometidas por mucometra. Macroscopicamente, os úteros mostraram variável distensão dos cornos, conferindo irregularidade ao órgão. Ao corte observou-se a presença de fluido mucoso e de coloração clara ou acinzentada. Ao exame histopatológico, o perimétrio e o miométrio estavam normais. Em alguns cas

ECTOPIA CORDIS TORÁCICA EM CANINO - RELATO DE CASO

A ectopia cordis é uma condição patológica caracterizada pelo posicionamento do coração fora da cavidade torácica, que acomete algumas espécies sendo rara em canídeos. O presente relato descreve a ocorrência de um caso de ectopia cordis em um canino natimorto. Ao exame necroscópico observou-se o desvio do coração, através de uma fissura mediana esternal, em localização peitoral associada a alterações no pericárdio.  Concluindo o diagnóstico de ectopia cordis tóraco-peitoral.

Testicular atrophy in Alouatta caraya kept in captivity report case / ATROFIA TESTICULAR EM Alouatta caraya MANTIDO EM CATIVEIRO: RELATO DE CASO

This study sought to assess anatomopathological aspects of a case of testicular atrophy in a specimen of Alouatta caraya kept in captivity at the Centro Nacional de Primatas - CENP/SVS/MS. Semen and biometrical exams were performed for the testicles. The results demonstrated that the animal presented azoospermia and in the biometric exam the right testicle presented an average volume of 0.438cm and the left one 0.407cm, values considerably below of those recorded in the literature for normal males of the species. Upon inspection, both testicles presented a firmer consistency that usual and the parenchyma cut was darker. The histopathological exam revealed a marked reduction in the number of seminiferous tubules; some were totally atrophied and hyalinized. In others there was an absence of the germinative epithelium and presence of vacuolized Sertoli cells while the interstitial (Leydig) cells were found proliferated. It is concluded that gonadopathy was the result of a degenerative process, with the lesion at a stage of chronicity. Keywords: Alouatta caraya, testicular atrophy, reproduction.

O presente estudo objetivou avaliar aspectos anatomopatológicos de um caso de atrofia testicular em Alouatta caraya mantido em cativeiro no Centro Nacional de Primatas - CENP/SVS/MS. Foi realizado exame de sêmen e biométrico dos testículos. Os resultados demonstraram que o animal apresentava azoospermia e no exame biométrico, o testículo direito apresentou volume médio de 0,438cm e o esquerdo 0,407cm, valores bastante inferiores aos registrados na literatura para machos normais da espécie. Na inspeção ambos os testículos apresentavam consistência mais firme que a habitual e ao corte o parênquima mostrou-se mais escuro. No exame histopatológico foi verificada redução acentuada no número de túbulos seminíferos, alguns se encontravam totalmente atrofiados e hialinizados, outros com ausência do epitélio germinativo e presença de células de Sertoli vacuolizadas enquanto que as células intersticiais (Leydig) se apresentavam proliferadas. Conclui-se que a gonadopatia resultou de processo degenerativo, estando a lesão num estágio de cronicidade. Palavras-Chave: Alouatta caraya, atrofia testicular, reprodução.
