Regarding remarkable prevalence of human hydatidosis and despite introduction of novel sensitive techniques such as ELISA for immunodiagnosis of disease in the word, there has not been much progress in that field in Iran. Preparation and purification of suitable antigens is the basic and first step in serodiagnosis of this disease. The present study, thus, is designed and carried out for pr...
The conclusions to be drawn from this study are that while there appears to be evidence of serological distinctions between B. abortus and B. melitensis cultures as studied by earlier workers, the experiments reported in this paper show no serological distinctions among the six strains used in the study. B. melitensis II and B. melitensis III were found to be identical with the bovine and swine...
Antigenic properties of the mouse mammary tumor virus (MTV or type B) particles and of the murine leukemia virus (MuLV or type C) particles have been studied by immunoelectron microscopy. Mouse mammary tumor cell lines producing either both type B and type C virus particles or only B or C type particles have been used. Mouse reticulum cell sarcoma and rat bone tumor cell lines producing type C ...
OBJECTIVE To measure levels of IgG antibodies against structurally related synthetic peptides of HLA-DRB1*0404, type XI collagen, and Proteus mirabilis in patients with rheumatoid arthritis (RA) and HLA-B*2705 and Klebsiella pneumoniae in patients with ankylosing spondylitis (AS), and to determine whether sera from RA and AS patients are cytotoxic for sheep red blood cells (SRBC) coated with HL...
b a ckground: west nile virus (wnv) is a mosquito-borne disease that can cause fatal infection in mammals in-cluding humans, dogs, horses, birds and reptiles. although west nile virus is an asymptomatic infection, especially it can cause neurologic disorders in humans and horses. the aim of this study was to the investigate virological pres- ence of wnv in horses in the black sea region of turk...
Antibodies to polymerized human albumin (poly-HSA) could not be detected by using sensitive methods (enzyme-linked immunosorbent assay and radioimmunoprecipitation) in sera from chronic carriers of hepatitis B surface antigen (HBsAg) or in serial bleedings from one chimpanzee infected with type A hepatitis virus and one infected with non-A, non-B hepatitis virus. By a solid-phase radioimmunoass...
Sera of C3H/Z/Dm mice bearing spontaneous mam mary tumors, sera of apparently normal C3H/Z/Dm mice at different ages, and a serum of an A/Dm mouse with spontaneous breast cancer were tested by the indirect immunoperoxidase method against cells of C3H/HeJ spon taneous mammary tumor line constantly producing type B or mouse mammary tumor virus particles. The sera were also tested against cells of...
Commercially prepared ABO blood-typing antisera have been tested for their ability to bind to murine laminin and their cytotoxic effects upon high and low metastatic variants of a murine fibrosarcoma. Previous studies have shown that alpha-D-galactopyranosyl end-groups comprise the major antigenic determinants on type B erythrocytes and that these same end-groups are present on murine laminin p...
BACKGROUND Control and elimination of human African trypanosomiasis (HAT) can be accelerated through the use of diagnostic tests that are more accurate and easier to deploy. The goal of this work was to evaluate the immuno-reactivity of antigens and identify candidates to be considered for development of a simple serological test for the detection of Trypanosoma brucei gambiense or T. b. rhodes...
Background: In spite of available, and sensitive screening assay for detection of hepatitis B virus surface antigen (HBsAg), occasional cases of post-transfusion hepatitis B virus infection are still observed. The aim of the present study was to assess the prevalence of positive anti hepatitis B core (anti-HBc) and presence of HBV-DNA in serum sample of healthy blood donors negative for both HB...
