Establishment and application of gene chip for Chikungunya virus and Sindbis virus

The microarray was established to detect Chikungunya virus and Sindbis virus with strong specific and high sensitivity.According to the conservative gene sequences of Chikungunya virus and Sindbis virus in GenBank,the E gene sequences of these two viruses and their primers were synthesized,and the oligonucleotide probes were designed based on the two virus,specific detection microarray was prepared.And its sensitivity,specificity and reproducibility were examined.The results showed that the sensitivity of this microarray was 100 times higher than ordinary PCR method.This microarray was specific for Chikungunya virus and Sindbis virus,which did not cross-react with other viruses such as Japanese encephalitis virus.This study established a microarray for detection of Chikungunya virus and Sindbis virus with high sensitivity and specificity,and it is suitable to epidemiological studies and species-specific detection.
