Multiplex PCR for differential identification of broad tapeworms (Cestoda: Diphyllobothrium) infecting humans.
The specific identification of broad tapeworms (genus Diphyllobothrium) infecting humans is very difficult to perform by morphological observation. Molecular analysis by PCR and sequencing represents the only reliable tool to date to identify these parasites to the species level. Due to the recent spread of human diphyllobothriosis in several countries, a correct diagnosis has become crucial to...
متن کاملMalignant insulinoma in a crab-eating fox (Cerdocyon thous)
This report describes a case of insulin-secreting pancreatic beta cell carcinoma in a crab-eating fox (Cerdocyon thous). The animal died approximately 60 days after the first clinical signs. At necropsy, a nodule (2 x 3 cm) was observed in the pancreas. Microscopic features were consistent with a pancreatic islet cell carcinoma. By immunohistochemistry, neoplastic cells were strongly positive f...
متن کاملThe first confirmed case of Diphyllobothrium latum in Brazil.
Diphyllobothriasis is an infection of the small intestine by the broad tapeworm Diphyllobothrium sp. The associated symptomatology is nonspecific, but megaloblastic anemia is a well-described complication. Although the infection is common in temperate regions, descriptions in South America have so far been limited to Chile, Peru, and a few cases in Argentina. This paper presents the first confi...
متن کاملDetection of antibodies to Neospora caninum in two species of wild canids, Lycalopex gymnocercus and Cerdocyon thous from Brazil.
Domestic dog (Canis domesticus) and the coyote (Canis latrans) are the only known definitive hosts for the protozoan Neospora caninum that causes abortion in dairy cattle. In the present study, antibodies to N. caninum were sought in three species of wild canids, Cerdocyon thous, Lycalopex gymnocercus and Dusicyon vetulus from Brazil. Antibodies to N. caninum were assayed by the indirect fluore...
متن کاملRabies Virus Related to Vampire Bats (Desmodus rotundus) Isolated from a Crab-Eating Fox (Cerdocyon thous) in Southeast Brazil
In this study, rabies virus was isolated from a naturally infected crab-eating fox [Cerdocyon thous] in a rural area of São Paulo State, Brazil. The sample was positive for the standard techniques used for rabies diagnosis. The isolate was antigenically characterized using anti-nucleoprotein monoclonal antibodies. Studies on molecular epidemiology by patterns of nucleotide substitution in the n...
