Resumo: Chikungunya virus (CHIKV) is a mosquito-borne pathogen responsible for epidemics of debilitating arthritic disease. The recent outbreak (2004-2014) resulted in an estimated 1.4-6.5 million cases, with imported cases reported in nearly 40 countries. The development of CHIKV-specific diagnostics - research tools is thus highly desirable. Herein we describe the generation - characterization of the first mAbs specific for the capsid protein (CP) of CHIKV. The antibodies recognized isolates representing the major genotypes of CHIKV, as well as several other alphaviruses, - were reactive in a range of assays including ELISA, Western blot, immunofluorescence - immunohistochemistry (IHC). We have also used the anti-CP mAb 5.5G9 in IHC studies to show that capsid antigen is persistently expressed 30 days post-infection in cells with macrophage morphology in a mouse model of chronic CHIKV disease. These antibodies may thus represent useful tools for further research, including investigations into the structure - function of CHIKV CP, - as valuable reagents for CHIKV detection in a range of settings.
