Abstract

Usporedno sa širenjem virusa reproduktivnog i respiratornog sindroma svinja (PRRSV) u Kini, sve su češće bile i njegove genske mutacije. Kako bi se ustanovila trenutačna prevalencija i evolucija PRRSV-a u pokrajini Shandong, s lokalnih farmi prikupljeno je 1528 uzoraka svinja različitih kategorija za koje je postojala sumnja na zarazu PRRSVom. Kompletan genomski slijed soja SDLY-27 PRRSV-a određen je tehnologijom sekvenciranja sljedeće generacije (NGS). Slijed je imao dužinu od 15 363 nukleotida (nt), a komparativna analiza cijeloga genomskog slijeda uputila je na to da je homolognost između sojeva SDLY 27 i 81 PRRSV-a iz Kine i uzoraka u banci gena iz drugih zemalja 61,9~96,4%. Ovo je prvo istraživanje koje je otkrilo rekombinantne sojeve iz višestrukih rekombinacija među linijama 8 (sojevi nalik na JXA1), 5 (sojevi RespPRRSV-MLV i VR2332) i podlinije 1,5 (sojevi nalik na NADC34) u Shandongu, Kina.Kao takvo, istraživanje pruža nove podatke o epidemiologiji PRRSV-a u Kini, posebno u pokrajini Shandong, a ujedno predstavlja i važnu referenciju za razvoj novih cjepiva te prevenciju i kontrolu bolesti uzrokovane navedenim virusom.
