A capture ELISA system was developed for diagnosis of visceral leishmaniasis (VL) using a monoclonal antibody raised against an antigen previously detected in the urine of VL patients. Urine samples from confirmed VL cases from Yemen, Nepal, Spain, Sudan and Brazil were tested in the capture ELISA in comparison with urine samples from endemic and non-endemic areas along with urine samples from ...

background: toxoplasma specific igm antibodies; the common serologic marker in diagnosis of acute toxoplasmosis has its own limitations. confirmatory testing with other markers, introduced as a complementary tool in distinguish acute and chronic infections is unusual in iran. in the present study, we investigated the cor-relation between the results of igm elisa, iga elisa, and igg avidity test...

background: cryptosporidium is a protozoan parasite with worldwide distribution. the aim of this study was to estimate the prevalence of cryptosporidium infection by antigen detection in faeces among immunocompromised patients referred to educational hospitals of ahvaz city, south-west of iran, 2009-2010. methods : fecal samples from 176 immunocompromised patients were collected and cryptospori...

background: echinococcosis is one of the most important helminthic zoonotic diseases in iran. intestinal scraping tech­nique (ist), the traditional method for diagnosis of the infection in definitive hosts, has many disadvantages including low sus­ceptibil­ity and being expensive, hazardous and laborious. detection of coproantigens in fecal samples by enzyme-linked immu­nosorbent assay (ca-elis...

background : toxoplasma gondii is a worldwide obligate intercellular parasite. felids are its definitive host and warm-blooded animals including humans are its intermediate host. the aim of this seroepidemiological study was to investigate the frequency of human infection using elisa method and related risk factors in tabriz city, northwestern iran. methods : in this cross sectional study, 171 ...

the objective of this study was to describe the seroprevalence rates of bluetongue virus (btv) in sheep in west and northwest provinces of iran. bluetongue virus, an economically important orbivirus of the reoviridae family, causes a hemorrhagic disease mainly in sheep and occasionally in cattle and some species of deer. bluetongue virus is transmitted between its mammalian hosts by certain spe...

objective: rubella is a viral disease with minor morbidity, unless it is contracted by a pregnant woman in early pregnancy that leads to congenitalrubella syndromes. rubella occurrence during the first trimester leads to fetal death or severe congenital defects.present study was conducted to survey the protection level against rubella in the pregnant women of gilan in iran,to be used for the va...
