ABSTRACT

This study aimed to investigate the frequency of geohelminthic contamination of public parks and squares in Curitiba, state of Paraná, Brazil, between August and December 2010. A total of 345 samples were collected from 69 sandboxes in different areas and were tested using the Faust, Lutz and Baermann parasitological techniques. Potential risk factors associated with soil contamination were also analyzed. A total of 36% of the samples (124/345) were positive for helminths and 65.2% of the areas (45/69) were classified as contaminated in one or more samples. The most commonly identified parasite eggs were Ancylostoma sp. (14.5%; 50/345); followed by Toxocara sp. (9.6%; 33/345) and the Strongyloidea superfamily (excluding hookworms) (2.3%; 8/345). The analysis on the epidemiological risk factors indicated that the presence of dogs and feces in the sandboxes increased the chances of contamination of the site. Use of fences had a protective positive impact that reduced soil contamination. Health education programs should be applied within the community to minimize the risk of human contact with dogs' feces. Use of fencing in these areas is highly recommended to prevent or reduce the users' contact with animal excrement.


Este estudo teve como objetivo investigar a frequência de contaminação por geohelmintos em parques e praças públicas de Curitiba, Paraná, Brasil, entre agosto e dezembro de 2010. Um total de 345 amostras foram coletadas de 69 caixas de areia em diferentes áreas e testadas usando-se as técnicas parasitológicas de Faust, Lutz e Baermann. Potenciais fatores de risco também foram analisados com a contaminação do solo. Um total de 36% (124/345) das amostras foram positivas, para helmintos e 65,2% (45/69) das áreas foram classificadas como contaminadas em uma ou mais amostras. Os ovos de helmintos mais identificados foram Ancylostoma sp. 14,5% (50/345), seguido por Toxocara sp. 9,6% (33/345) e Strongyloidea superfamília (excluindo ancilostomídeos) 2,3% (8/345). A análise dos fatores de risco epidemiológico indicou que a presença de cães e fezes nas caixas de areia aumenta a probabilidade de contaminação do local. O uso de cercas teve um impacto positivo de proteção e redução da contaminação do solo. Programas de educação em saúde devem ser aplicados dentro da comunidade para minimizar o risco do contato humano com as fezes dos cães. O uso de cercas nessas áreas é altamente recomendado, para prevenir ou reduzir o contato dos usuários com excrementos dos animais.

ABSTRACT

An intact adult female Poodle dog was presented with a history of an increase in volume in the left and right mammary inguinal glands. The histopathological examination revealed a proliferation of spindle cells arranged in bundles with concentric arrangements surrounding blood vessels, occasionally collapsed. Three weeks after the surgery, the animal presented a recurrence of the tumor that extended from the left inguinal mammary gland to the vulva. Necropsy revealed direct invasion of the abdominal cavity by the tumor and pulmonary metastasis. The definitive diagnosis of hemangiopericytoma was made by histopathological and immunohistochemical examination. Pulmonary metastasis of CHP (canine hemangiopericytoma) is rare and there is no previous report of direct invasion to the abdominal cavity as observed in the present case.


Uma cadela adulta, intacta, da raça Poodle, apresentou histórico de aumento de volume na mama inguinal direita. O exame histopatológico revelou proliferação de células fusiformes dispostas em bandas e arranjos concêntricos ao redor de vasos, os quais se apresentavam ocasionalmente colapsados. Três semanas após a cirurgia, o animal apresentou recorrência do tumor que se estendia até a vulva. No exame necroscópico, observou-se que a massa invadia a cavidade abdominal e presença de metástase no pulmão. O diagnóstico definitivo de hemangiopericitoma foi realizado por meio dos exames histopatológico e imuno-histoquímico. A metástase pulmonar do hemangiopericitoma canino é rara e não há relatos prévios de invasão direta para cavidade abdominal, como observado no presente caso.

ABSTRACT

The aim of this study was to evaluate the viability of bull spermatozoa collected from the cauda epididymis stored at 18-20°C, which were compared with semen collected by electro-ejaculation method and preserved at 5°C. Ten pairs of testes from Tabapuã bulls were removed by orchiectomy and stored for 6 (G6), 12 (G12), 18 (G18), 24 (G24) and 30 (G30) h at room temperature (18-20°C). Seven days before orchiectomy, semen was collected by electro-ejaculation method. The sperm parameters evaluated were: sperm motility, vigor, concentration, morphology and acrosome defects. Sperm motility declined (p<0.05) when spermatozoa were stored for 30 h in the epididymis. The spermatozoa from the epididymis showed lower sperm motility than that of spermatozoa collected via electro-ejaculation. There was a little expressive decrease in sperm vigor and increased in morphological defects with storage time, but the acrosome integrity was not affected. Cold storage (5°C) maintained sperm viable for 15 to 40.8 h. Thus, it was possible to recover viable sperm with 41.25% of motility from the cauda epididymis stored at room temperature of 18-20°C for 30 h. There were differences between the ejaculated and epididymal sperm for the bulls and the conservation at 5°C allowed short-term preservation of the gametes.

ABSTRACT

Brazilian Spotted Fever (BSF) is a lethal rickettsiosis in humans caused by the bacteria Rickettsia rickettsii, and is endemic in some areas of Brazil. Horses and dogs are part of the disease's life cycle and they may also serve as sentinel animals in epidemiological studies. The first human BSF case in the State of Paraná was reported in 2005. The present study was conducted in the municipality of Almirante Tamandaré, where no previous case of BSF was reported. Serum samples were collected from 71 horses and 20 dogs from nine properties in the area. Ticks were also collected from these animals. All farmers completed a questionnaire about their knowledge of BSF and animal health management. Serum samples were analyzed by indirect immunofluorescent-antibody assay (IFA) using R. rickettsii and R. parkeri as antigens. Ticks were analyzed by PCR for Rickettsia sp., and all of them were PCR-negative. Six horses (8.45 percent) and 4 dogs (20 percent) were identified as seropositive. Farmers were not aware of the correlation between the presence of ticks and risk of BSF. Although a non-endemic area, Almirante Tamandaré is a vulnerable environment for BSF and effective tick control measures are required.


A Febre Maculosa Brasileira (FMB) é uma riquetsiose letal para humanos, causada pela bactéria Rickettsia rickettsii, e é endêmica em algumas regiões brasileiras. Equinos e cães podem participar do ciclo da doença e podem também servir como sentinelas em estudos epidemiológicos. O primeiro caso humano relatado no Estado do Paraná ocorreu em 2005. O presente estudo foi realizado no município de Almirante Tamandaré, região onde não há relatos de casos de FMB. Foram coletadas amostras de sangue de 71 cavalos e 20 cães em nove propriedades rurais na região. Carrapatos também foram colhidos dos animais. Todos os proprietários responderam a um questionário sobre o manejo sanitário dos animais e o conhecimento a respeito da FMB. As amostras de soro foram processadas pela técnica de Reação de Imunofluorescência Indireta (RIFI), utilizando-se os antígenos de R. rickettsii e R. parkeri. Os carrapatos foram analisados por PCR para Rickettsia sp. e todos foram negativos. Seis cavalos (8,45 por cento) e 4 cães (20 por cento) foram identificados como soropositivos. Todos os proprietários desconheciam a relação de carrapatos com a FMB. Embora considerada uma área não endêmica, Almirante Tamandaré é um ambiente vulnerável à FMB e um controle eficiente de carrapatos deve ser implementado.
