Chikungunya is usually a benign disease, and little is known on the occurrence of severe clinical complications. We describe a 12-year-old boy with rapid onset septic shock and multi-organ failure associated with chikungunya fever. Severe sepsis and septic shock can be associated with chikungunya.
Capripox viruses of small ruminants, namely goatpox virus (GTPV) and sheep pox virus (SPPV) are responsible for important contagious diseases that are enzootic to the Indian sub-continent, Africa and the Middle East. In the present study, recombinant F13L and P32 proteins of GTPV were expressed in prokaryotic system, purified and confirmed in Western blot in order to evaluate their diagnostic potential. Full length F13L ( 1 M-L 370 aa) and truncated P32 ( 20 V-S 270 aa) genes of GTPV-Uttarkashi strain were cloned into pET-33b(+) vector, over-expressed in prokaryotic system and purified as histidine-tagged protein using Ni-NTA affinity chromatography under denaturing conditions and passive elution method, respectively. The recombinantF13Land P32 proteins lacked fusion tag from vector except histidine tag for purification as analyzed by SDS-PAGE. Expression was confirmed with Western blot using anti-GTPV serum. The purified recombinant F13L and P32 proteins can be used potential diagnostic antigen/s either individually or in combination for sero-diagnosis of capripox virus infections.
Foot‐and‐mouth disease (FMD) is a major viral disease in farm animals. In the present study, seven monoclonal antibodies (mAbs) were produced against the FMD virus (FMDV)‐encoded RNA‐dependent RNA polymerase (3D protein) and characterized. Screening of mAb reactivity against three overlapping fragments of the 3D protein expressed in Escherichia coli revealed that the binding sites of all the mAbs were confined to the N‐terminal one‐third of the 3D protein. A selected mAb was utilized for detecting FMDV in the infected cell culture and tissues obtained from FMDV‐infected animals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
