by immunizing mice with killed whole bacterial cells of brucella abortus s (99), a panel of six hybridomas producing monoclonal antibodies (mab) specific for the surface antigens of this bacterium were produced. elisa was used to screen the hybridoma supernatants. immunoblots of the cell extract indicated that three mab were specific for s-lps (ba-1, ba-2, ba-3) and three others were reactive w...
objective(s) tuberculosis (tb) is the leading cause of mortality among the infectious diseases, especially in developing countries. one of the main goals in tuberculosis research is to identify antigens which have the ability of inducing cellular and/or humoral immunity in order to use them in diagnostic reagents or vaccine design. the aim of this study was to clone and express the tb'0.4 ...
background: ornithobilharziosis as one of the parasitic infections may give rise to serious economic problems in animal husbandry. the aim of the study was to prepare and compare the somatic and excretory-secretory (es) antigens of o. turkestanicum in gel diffusion test. methods: excretory-secretory (es) and somatic antigens of ornithobilharzia turkestanicum were prepared from collected worms ...

background and objective: the outcome of hepatitis b virus (hbv) infection may be influenced by host factors like human leukocyte antigen (hla). we have investigated hla-a and drb1 alleles in patients with persistent hepatitis b infection compared to subjects who had spontaneously recovered from hbv infection. to complete the findings of this study we performed another survey in certain hla all...
extramedullary plasmacytoma is a rare neoplasm characterized by monoclonal proliferation of plasma cells. most lesions occur in the head and neck, primarily in the upper aerodigestive tract. the nasal cavity and nasal septum are the most common sites of occurrence. in this report, three patients admitted in our clinic with history of nasal obstruction and/or epistaxis. patients were diagnosed w...
