hydatid cyst is an important and zoonotic infection caused by cystic stage of echinococcus granulosus. it is a major and economic problem in most areas of the world that livestock are kept such as iran. in this study, a total of 111 buffalo,s sera from center of buffalo sperm preparation (cbsp), orumia (west azarbayjan province, iran, 2003) were examined for the presence of hydatidosis by using...

BACKGROUND Penicillium marneffei is a dimorphic fungus endemic in Southeast Asia. It can cause fatal penicilliosis in humans, particularly in HIV-infected people. Diagnosis of this infection is difficult because its clinical manifestations are not distinctive. Specialized laboratory tests are necessary to establish a definitive diagnosis for successful management. We have demonstrated previousl...

AIMS To evaluate an antigen capture enzyme linked immunosorbent assay (ELISA) which detects a carbohydrate epitope on the excretory-secretory (ES) antigens of Toxocara canis in clinical practice. METHODS Serum specimens from healthy adults, patients with acute visceral larva migrans, ocular and inactive toxocariasis, and with other helminth infections were examined by two site antigen capture...

Recruitment of natural antibodies towards tumour cells for their elimination by the immune system could be a highly specific and efficacious therapeutic strategy. While l-rhamnose has already been explored as suitable antigen antibody recruitment, we here report first rhamnose-based glycomimetic to used such purpose. The is designed more hydrolytically enzymatically stable than rhamnosides, pro...

Early definitive diagnosis of dengue virus infection may help in the timely management of dengue virus infection. We evaluated the Standard Diagnostics (SD, South Korea) dengue virus nonstructural protein NS1 antigen enzyme-linked immunosorbent assay (SD dengue NS1 Ag ELISA) for the detection of dengue virus NS1 antigen in patients' sera, using a total of 399 serum samples in a comparison with ...

Puumala virus (Bunyaviridae family, Hantavirus genus) causes a mild form of hemorrhagic fever with renal syndrome (HFRS) called nephropathia epidemica in northern and central Europe. Serological tests are used for diagnosis, but antigen production is difficult because the virus grows poorly in tissue culture. We expressed the N protein (nucleoprotein) of Puumala virus via the Semliki Forest vir...

fasciolosis diagnosis, due to low sensitivity of coprological diagnostic method has been challenging for a long period. in this study, dot-elisa, one of the simplest and the most sensitive tests in this regard, was evaluated using excretory-secretory antigens of fasciola hepatica to diagnose human fasciolosis three groups consisting of patients infected with fasciolosis (n= 95), patients with o...

background: it is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum psa in iranian population. objective: to determine age-specific reference ranges for serum prostate-specific antigen (psa) concentration and psa density (psad) and prostate volumes in a population of he...
