Background & Aims: Hepatitis B virus is one of the causes of acute and chronic hepatitis. Due to multiple hospitalization and blood transfusion, thalassaemic patients are at higher risk of this infection. Duration of the immunity after vaccination in this high-risk group and the need for booster vaccination is uncertain. The aim of this study was to find antibody titration and immunity to Hepat...

Avian influenza (AI) is a highly contagious disease in poultry and outbreaks can have dramatic economic and health implications. For effective disease surveillance, rapid and sensitive assays are needed to detect antibodies against AI virus (AIV) proteins. In order to support eradication efforts of avian influenza (AI) infections in poultry, the implementation of “DIVA” vaccination strategies, ...

Background: Monoclonal antibody technology allows identification of amastigote-specific antigen in human tissue biopsies and search for a suitable vaccine candidate, which may induce a long lasting immunity. Objectives: Production and partial characterization of seven monoclonal antibodies against Leishmania tropica promstigotes. Methods: Seven murine monoclonal antibodies of the IgG isotype we...

Objective(s): Leishmaniasis is endemic in 88 countries. Amastigote forms of Leishmania are experts at exploiting host cell processes to establish infection. Monoclonal antibodies are key reagents used in the diagnosis of infectious and non-infectious diseases. The aim of this study was to produce monoclonal antibodies against axenic amastigotes of the Leishmania infantum strain in Iran.Material...

conclusions the prepared antibody can be used for the development of an elisa kit to assay afm1 in milk and other biological fluids. background aflatoxins are the most extensively studied group of mycotoxins produced by molds, especially the aspergillus group, which are highly toxic to animals and humans. objectives since immunoassay is a simple and rapid method for the analysis of many toxic s...

88 patients with drug addition were evaluated for hbsag, hbeag, anti-hbc, anti hiv syphlisis and anti-toxoplasma antibodies. 48 of them were male and 40 were female. the range of their ages was between 19 to 49 years and their addiction time were between 6 month to 30 years. the results show that 5.6% of the patients have hbsag in their blood serum and 40.9% of them have anti-hbe antibodies. al...

background: diagnosis and treatment of neuropsychiatric lupus is still a major challenge in clinical practice. we investigated the association between depression and anti-ribosomal p (anti-p) antibodies in a sample of iranian patients with systemic lupus erythematosus (sle). materials and methods: th is cross-sectional study was conducted on adult patients with sle referring to a referral out-p...
