Dioctophyme renale in wandering dogs in Pelotas, South of Brasil / Dioctophyme renale em cães errantes no município de Pelotas, Sul do Brasil

Abstract This study aimed to verify the occurrence of Dioctophyme renale in stray dogs in the city of Pelotas, in the state of Rio Grande do Sul, Brazil. The Laboratório Regional de Diagnóstico of the Universidade Federal de Pelotas received 146 wandering dogs for necropsy, sent by the City Hall of Pelotas from March 2012 to January 2020. Among the necropsied animals, seventeen dogs (11.64%) were diagnosed with dioctophymosis. Among these dogs, 11 were parasitized with one specimen in the right kidney, two dogs presented two specimens in the right kidney, and in other two dogs, the parasites were in the abdominal cavity. In one dog, two parasites were found in the left kidney; in another dog, both kidneys were parasitized, with two parasites in the right kidney and one in the left kidney. The data obtained in this study showed that the occurrence of D. renale in stray dogs in the city of Pelotas is high, and D. renale mainly parasitizes the right kidney.

Resumo Este trabalho possui como objetivo verificar a ocorrência de D. renale em cães errantes do município de Pelotas, no Rio Grande do Sul, Brasil. O Laboratório Regional de Diagnóstico da Universidade Federal de Pelotas recebeu 146 cães errantes para necropsia, encaminhados pela Prefeitura Municipal de Pelotas, no período de março de 2012 a janeiro de 2020.

Em dois animais, os parasitas estavam na cavidade abdominal; em um animal havia, dois parasitas no rim esquerdo e noutro animal os dois rins estavam parasitados, tendo dois exemplares no rim direito e um exemplar no rim esquerdo. Os dados obtidos neste trabalho permitem concluir que é elevada a ocorrência de D. renale nos cães errantes do município de Pelotas, parasitando principalmente o rim direito.

A identidade brasileira e o complexo de vira-lata: uma interpretação da psicologia simbólica junguiana / Brazilian identity and the stray dog complex

Baseado no arquétipo de alteridade, o autor estuda o símbolo do complexo do vira-lata associado pejorativamente à identidade multicultural brasileira, para descrever seus aspectos admiráveis centralizados no símbolo da miscigenação. Considerando simbolicamente a figura de dom Pedro II, ele a associa com o lado positivo do símbolo do vira-lata, pelo fato de o imperador, denominado pejorativamente Pedro Banana, ter repudiado as características luxuosas e soberbas inerentes às elites europeias e ter se dedicado a valorizar a simplicidade da figura do estadista no amor por seu país.

The author analyses the symbol of the stray dog complex associated to a Brazilian inferiority complex and interprets its valuable meaning considering miscegenation in the Brazilian multicultural society. The symbol of the stray dog is associated to the personality of dom Pedro II, emperor of Brazil for almost fifty years, and points out the derogatory qualities attributed to the emperor to the point of nicknaming him Pedro Banana. It corresponds to qualities he cherished such as simplicity and aversion to vanity and luxury resembling the stray dog.

Prevalencia de leptospirosis en perros vagos capturados en la ciudad de Temuco, 2011 / Prevalence of leptospirosis in vague dogs captured in Temuco city, 2011

Background: Leptospirosis, a bacterial disease of worldwide distribution, affects various animals and is considered a zoonosis. It can be transmitted directly or indirectly, mainly through contact with the carrier's urine and entering the body through mucous membranes or skin. In the city of Temuco, there are no epidemiological studies of canine leptospirosis and the country data are scarce. Objective: To determine the prevalence of leptospirosis in stray dogs of the city of Temuco. Material and Methods: In a cross- sectional study, 400 dogs admitted to Temuco Kennel during the year 2011 were sampled. Blood samples were analyzed using a modified commercial ELISA kit. Results: The prevalence of leptospirosis was 21.3%. Positive cases were concentrated in dogs 5 to 8 years of age, independent of gender. Discussion: The high prevalence found demonstrates the need for further studies to better understand the epidemiology of the disease and to establish prevention and control measures.

Introducción: La leptospirosis es una enfermedad bacteriana de distribución mundial, afecta a diversos animales y es considerada una zoonosis. Puede transmitirse de manera directa o indirecta, principalmente por contacto con orina de un animal portador, ingresando al organismo a través de las mucosas o la piel reblandecida por la humedad. En la ciudad de Temuco no existen estudios epidemiológicos de leptospirosis canina y los datos en el país son escasos. Objetivo: Realizar un estudio de corte transversal, para determinar la prevalencia de leptospiro-sis en perros vagos de la ciudad de Temuco. Material y Métodos: Se procuró muestras de un total de 400 perros ingresados al Canil Temuco durante el año 2011. Se recolectaron muestras de sangre para luego ser analizadas mediante un kit comercial de ELISA modificado. Resul- encontrada demuestra la necesidad de mayores estudios tados: La prevalencia de leptospirosis en perros vagos de tendientes a comprender mejor la epidemiología de la la ciudad de Temuco fue 21,3%. La mayoría de los casos enfermedad y poder establecer medidas de prevención positivos se concentran en perros de 5 a 8 años de edad y control que eviten el riesgo de exposición del hombre e independiente del sexo. Discusión: La alta prevalencia a esta zoonosis.

Serological Survey for Canine Parvovirus Type 2a (CPV-2a) in the Stray Dogs in South Korea

Canine parvovirus type-2 (CPV-2) is one of the major diarrhea-causing agents, inducing acute hemorrhagic gastroenteritis in puppies. In this study, we conducted a seroepidemiological survey of CPV-2a in stray dogs in South Korea. In total, 405 canine sera, collected between 2006 and 2007, were screened for the presence of antibodies against CPV-2a using a hemagglutination inhibition (HI) assay. The positive rate in stray dogs tested for CPV-2a was 93.8%. The regional CPV-2a prevalence was 100% (8/8) in Jeju, 95.1% (232/244) in Gyeonggi, 94.7% (36/38) in Jeonra, 92.9% (13/14) in Gangwon, 92.7% (38/41) in Chungcheong, and 88.3% (53/60) in Gyeungsang province. No significant difference in the seropositive rate was found between male (93.6%) and female (94.0%) dogs. Analysis of the distribution of HI titer against CPV-2a according to the age of the stray dogs showed a linear increase in seroprevalence with age, although the association with age was not statistically significant. The incidence of stray dogs showing an HI antibody titer above 1:5120 was estimated to be 26.2%. Thus, the presence of high HI antibody against CPV-2a may indicate circulation of CPV-2a in stray dogs.

A Survey of Ectoparasite Infestations in Stray Dogs of Gwang-ju City, Republic of Korea

This study was designed to investigate the incidence of ectoparasite infestation among stray dogs in Gwang-ju City, Republic of Korea. A total of 103 stray dogs collected in the Animal Shelter of Gwang-ju City from November 2003 to August 2005 were investigated in this study. Ectoparasites of one or more genera were detected in 45.6% (47 / 103) of the dogs examined for dermatologic lesions and/or skin scrapings (from 3-5 affected areas). Otodectes cynotis was found to be the most frequent parasite (22.3%, 23 / 103), followed by Sarcoptes scabiei var canis (19.4%, 20 / 103), Ctenocephalides canis (6.8%, 7 / 103), Demodex canis (4.9%, 5 / 103), and Trichodectes canis (1.0%, 1 / 103). Monospecific infestation was found in 83.0% (39 / 47) of the affected dogs, whereas concurrent infestations with 2 or more ectoparasites per animal were found in 17.0% (8 / 47) of the affected dogs. Trichodectes canis is reported for the first time in the Republic of Korea. Dogs less than 1 yr old were more heavily infected than other age groups (66.7%), and small-sized dogs of less than 3 kg body weight were more heavily infected than larger dogs (41.7%).
