MEDIA PENELITIAN DAN PENGEMBANGAN KESEHATAN(2015)
Abstract
Measles is caused by virus belonging to the genus Morbilivirus and Family Paramyxoviridae. Measles is still a public health problem because outbreak of measles still found in Indonesia. Outbreak is suspected as a result of differences in antigenicity between vaccine strains used with wild-type measles virus strains circulating in Indonesia. This study aims to get genetic characteristics of wild-type measles virus haemagglutinin gene in Indonesia. The specimens were used 27 viral isolates from 17 provinces period 2003-2010. Viral isolates examined by RT-PCR and sequencing with Sanger method. Sequencing analysis were conducted using Bioedit 7.0 and MEGA 4.0 software. The results showed 10 amino acid differences between the vaccine strain measles virus CAM-70 and wild-type measles virus in position D416N; K424T; V451M; N455T; V466I; I473T; F476L; Y481S or Y481N; H495N; G505D. Conclusion: There is a difference between the genetic characteristics of wild-type measles virus in Indonesia and vaccine strain CAM-70.
