ASFV isolates from Lithuania and Poland shared 100% nucleotide identity with eastern European isolates in standard markers but contained a unique tandem repeat sequence insertion identical to isolates from Belarus and Ukraine.
Observational (n=25)
Genetic analysis of a novel tandem repeat sequence marker confirmed that the 2014 African swine fever virus outbreaks in Poland and Lithuania likely originated from Belarus.
African swine fever virus (ASFV) was first reported in eastern Europe/Eurasia in 2007. Continued spread of ASFV has placed central European countries at risk, and in 2014, ASFV was detected in Lithuania and Poland. Sequencing showed the isolates are identical to a 2013 ASFV from Belarus but differ from ASFV isolated in Georgia in 2007.
Gallardo et al. (2014) conducted an observational in African Swine Fever (n=25). Genetic sequencing of ASFV isolates was evaluated on Nucleotide sequence identity and tandem repeat sequence (TRS) variations. ASFV isolates from Lithuania and Poland shared 100% nucleotide identity with eastern European isolates in standard markers but contained a unique tandem repeat sequence insertion identical to isolates from Belarus and Ukraine.
