Pesticides are used globally for enhancing crop yields. However, their excessive use/misuse, especially in the developing countries, results in widespread food and environmental contamination. Therefore current methods such as gas chromatography and high-performance liquid chromatography have been used successfully, with great sensitivity and reliability, for analysis of many pesticides. Howeve...

The aim of this study was to estimate the frequency of human toxocariasis in Cauday district, Cajamarca, Peru, using a dot-ELISA test. From June to October 2005, a total of 256 adult subjects were studied. Blood samples were collected for serology by a dot-ELISA test and for hematological examination. Parasitological examination was also carried out in stool samples to check cross-reactions in ...

The larval stage of Taenia pisiformis, also known as Cysticercus pisiformis, is the causative agent of cysticercosis and the cause of severe health problems in rabbits that negatively impacts on husbandry production. To date, there is no fast detection method to identify early infections in rabbits. In the present study, a new dot-ELISA-based on an endogenous antigen fatty acid-binding protein ...

hydatidosis is caused by the larval stage (metacestode) of the tapeworm echinococcus granulosus. the disease has a worldwide distribution and iran is in the hyperendemic region. in the present study, the efficacy of dot-elisa and pcr tests for detecting hydatid cysts was investigated. blood samples and samples from liver and lung were collected from a number of 256 cattle and 132 water buffaloe...

Toxocaracati is one of the most important and widespread of the helminth zoonosis. In the present study, helminthosis due to Toxocaracati in 55 stray cats in Tehran was studied by necropsy. In addition, two different diagnostic methods, including serological and coprological tests, for infection with this parasite were compared. The dot-ELISA assay used Toxocaracati crude antigens to evaluate t...

AIMS To evaluate different hybridisation techniques to detect and type human papillomavirus (HPV) DNAs amplified by consensus primer polymerase chain reaction (PCR) in biopsy and cytological specimens. METHODS A hybrid capture-immunoassay in microtitre wells was performed to detect HPV sequences amplified by PCR and typed by specific oligoprobes. Consensus primers were used to amplify a seque...
