Fifty years after the introduction of the first effective antimicrobial agents against Mycobacterium tuberculosis, this pathogen continues to be a tremendous public health problem. The rise in the number of resistant strains and the difficulties involved in the therapy of tuberculosis in immunocompromised AIDS patients have renewed the interest in the development of effective vaccines. To evalu...
The candidate malaria vaccine RTS,S/AS01(E) provides significant but partial protection from clinical malaria. On in vitro circumsporozoite protein (CSP) peptide stimulation and intra-cellular cytokine staining of whole blood taken from 407 5-17 month-old children in a phase IIb trial of RTS,S/AS01(E), we identified significantly increased frequencies of two CSP-specific CD4+ T cells phenotypes...
Experimental uveitis in rabbits was induced by single intraocular antigen injection. Treatment with 6-MP for 14 days suppressed the allergic inflammation and antibody response. A good correlation was demonstrated between the degree of uveitis and the antibody titer.
BACKGROUND The present study was conducted to evaluate and compare a fast-ELISA (F-ELISA) method versus standard-ELISA (S-ELISA) to diagnose human fasciolosis. METHODS Serum samples were obtained from 35 individuals infected with fasciolosis, 27 infected with other parasitoses and 22 from healthy people. The samples were examined with S-ELISA (30-minute incubation periods) and F-ELISA (10-min...
A vaccine for equine coronavirus (ECoV) is so far unavailable. Bovine coronavirus (BCoV) is antigenically related to ECoV; it is therefore possible that BCoV vaccine will induce antibodies against ECoV in horses. This study investigated antibody response to ECoV in horses inoculated with BCoV vaccine. Virus neutralization tests showed that antibody titers against ECoV increased in all six horse...
"Acute" and "convalescent" samples of serum from 40 patients from a localized outbreak of influenza were tested for mouse-protective antibodies against 7 different strains of influenza virus, which included 2 laboratory strains representative of "group A" and of "group B," and 5 strains from the investigated outbreak. The latter 5 strains although not identical were related to each other and to...
Low efficacy of peptide vaccines limits their potential application. We developed a powerful strategy to produce epitope-specific antibodies using peptides. Immunization with novel formula into mice showed target-specific prophylactic and therapeutic effects against tumors. Our strategy will be useful for rapid eiptope screening, therapeutic antibody production and cancer vaccine development.
Plasmodium vivax remains an important cause of malaria in South America and the Asia-Pacific. Naturally acquired antibody responses against multiple P. vivax proteins have been described in numerous countries, however, direct comparison of these responses has been difficult with different methodologies employed. We measured antibody responses against 307 P. vivax proteins at the time of P. viva...
Four isolates of porcine rotavirus-like virus (PRVLV) infected MA104 cells and induced syncytium formation after low-speed centrifugation of the inoculum onto the monolayer. Ten of 44 (23%) Ohio swine sera had PRVLV antibodies when tested by indirect immunofluorescence, using PRVLV-infected MA104 cell monolayers as antigen.
