Methods: This observational case series includes 14 patients with clinical features of CHIKV infection and associated optic neuritis. Complete ophthalmic evaluations were performed, as well as other examinations, including Mantoux test, Widal test, blood profile, color vision, neuroimaging, visual fields, visual evoked potentials, VDRL test, and enzyme-linked immunosorbent assay for CHIKV-speci...

A new type of immunoassay (enzyme-linked immunosorbent assay, ELISA) has been used for the detection of antibodies against Salmonella 0 antigens. The results show that ELISA is specific and highly sensitive. When compared with the Widal reaction, passive hemagglutination, and quantitative precipitation, ELISA was shown to be more sensitive. In addition, immunoglobulin G and immunoglobulin M ant...
