Changes in the genome of African swine fever virus (Asfarviridae: Asfivirus: African swine fever virus) associated with adaptation to reproduction in continuous cell culture

Abstract: Введение. Возбудитель африканской чумы свиней (Suidae) (АЧС) -крупный (175-215 нм) двухцепочечный ДНК-вирус, относящийся к семейству Asfarviridae. К настоящему времени секвенирован и подробно проанализирован только геном штамма BA71V, адаптированного к клеточной культуре Vero. Целью данной работы явился сравнительный анализ полногеномного сиквенса исходного изолята вируса АЧС Odintsovo 02/14 и 2 штаммов, полученных на уровне 30 и 50 пассажей и адаптированных к росту в клеточной культуре CV-1. Материал и методы… Show more

“…To validate this cell culture for ASFV isolation and titration, different viruses were used to infect PBMP and porcine spleen cell culture (PSC) (n = 3) [29,30]. The viruses used included Arm07 (Genotype II), ASFV/ARRIAH/CV-30 (Genotype II, adapted to CV-1 cell culture by performed 30 consecutive passages) [29], Lisbon 60 (Genotype I), K49 (Genotype I), and Mozambique-78 (Genotype V), as well as 18 other isolates taken from different regions of the Russian Federation and all representing Genotype II (Supplementary Table S1). The 96-well cell culture plates were infected at 100 HADU 50 /cm 3 , and titer (in lg HADU 50 /cm 3 ) was calculated on the fifth day after inoculation as described by de Leon et al in 2013 [4].…”

“…Адаптация изолята Odintsovo 02/14 на перевиваемой культуре клеток CV-1 в течение 30 последовательных пассажей (вирус назван АЧС/ВНИИЗЖ/CV-1/30) привела к снижению гемадсорбции с 40-50 до 20-30 эритроцитов, прикрепленных к инфицированной клетке. Заражение свиней таким вариантом показало снижение летальности до 16,7 % и устойчивость выживших животных к контрольному заражению вирулентным изолятом Arm 07 (46)(47)(48).…”
