ABSTRACT

Trichostrongylid em ovelhas foi estudado no Distrito Zhob, Balochistan. Foram coletados 120 tratos gastrointestinais (GIT) de ovelhas do matadouro do distrito. Estas amostras foram processadas para isolamento e identificação de nematódeos tricostrônquicos no Laboratório do Hospital Veterinário do Distrito Zhob. A taxa de prevalência geral foi de 39,1% em machos e 60,8% em fêmeas (p=0,001). A taxa de prevalência em duas raças viz Balochi e Rakhshani foi de 58,3% e 41,6%, respectivamente (p=0,01). A prevalência da espécie observada com Trichostrongylus foi 19,1%, Haemonchus foi 20,8%, Cooperia foi 29,1% e Nematodirus foi 30,8% (p=0,087). Quanto a quantidade de espécies infestadas pelas ovelhas, um único tipo de parasita estava em 32,5% de animais, dois tipos de espécies parasitárias em 36,3% dos animais e três tipos de espécies parasitárias em 30,8% dos animais (p=0,366).(AU)

ABSTRACT

Foram examinadas, pelo Laboratório de Doenças Parasitárias (LADOPAR) da Universidade Federal de Pelotas, 2.680 amostras de fezes de ovinos, advindas da região sul do estado do Rio Grande do Sul, Brasil, entre os anos de 2015 a 2017. A técnica coproparasitológica de Gordon & Whitlock (1939) foi utilizada para o diagnóstico. Das amostras analisadas, 86,5% apresentaram-se positivas para algum helminto gastrintestinal e oocistos de protozoários, sendo a infecção mais prevalente por ovos da ordem Strongylida. Através dos resultados obtidos, conclui-se que helmintoses gastrintestinais estão presentes nas criações de ovinos da região sul do estado e, através de exames coprológicos, é possível implementar medidas sanitárias e preventivas nos rebanhos.


A total of 2,680 samples of sheep feces from the southern region of the State of Rio Grande do Sul, Brazil, from 2015 to 2017 were examined by the Laboratory of Parasitic Diseases (LADOPAR) of the Federal University of Pelotas. Gordon & Whitlock's (1939) coproparasitological technique was used for the diagnosis. 86.5% of the samples analyzed were positive for some gastrointestinal helminth and protozoan oocysts, being the most prevalent infection by eggs of Strongylida order. Through the results obtained, it is concluded that gastrointestinal helminths are present in the sheep farms of the southern region of the state and, through coprological exams, it is possible to implement sanitary and preventive measures in the herds.

ABSTRACT

Carnivorous mammals are a trophic guild with an important role in the dissemination of parasite infective stages (larvae, eggs, cysts, and oocysts). In the present study, new samples of coprolites attributed to carnivorous mammals, obtained from 2 archaeological caves, were analyzed for the presence of parasites with the aim to increase the knowledge about parasites in rockshelters that could have spread to humans and other mammals. To this purpose, fragments of 3 coprolites from Cerro Casa de Piedra, cave 5 and cave 7, were examined. Coprolites were rehydrated in aqueous trisodium phosphate and processed by spontaneous sedimentation. High parasite richness was observed and new parasite species for archaeological contexts were found. The parasitological findings in Puma concolor coprolites associated with caves suggest the importance of these carnivores in the dissemination of parasites in areas with high re-use of space and steady conditions of temperature, humidity, and radiation.

ABSTRACT

The breeding of wild animals for commercial purposes is becoming more frequent nowadays. This situation has led to an increase in contact rates between wild and domestic animals, with subsequent reciprocal transmission of parasites. In this study, we characterized the gastrointestinal and blood parasites of a group of 15 semi-captive guanacos (Lama guanicoe). We characterized gastrointestinal parasites by analyzing fecal samples through the sedimentation-flotation technique and hemoparasites by using blood smears stained with Giemsa. We found several gastrointestinal parasites including Nematoda and protozoans. The most frequently found parasites were Nematodirus sp. and Eimeria sp. In contrast with previous studies, neither Cestoda nor Fasciola were found. The only hemoparasite detected was Mycoplasma haemolamae, a parasite already described in llamas and alpacas. We conclude that the most frequent gastrointestinal parasites of semi-captive guanacos were nematodes and protozoans. Also, the hemoparasite M. haemolamae seems to be prevalent among captive populations of South American camelids. Finally, captive guanacos share several parasites with the traditional livestock. Therefore, keeping captive or semi-captive guanacos without an adequate sanitary protocol might have adverse consequences to adjacent traditional cattle farming and/or for wild animals.
