Porcine circovirus type 3 (PCV3) was detected in Shandong, China. One hundred and thirty-two of 222 (59.46%) samples were PCV3 positive, while 52 of 132 (39.39%) samples were co-infected with PCV2. There were no clinical signs of infection in either multiparous sows or live-born infants. Two strains of PCV3 were indentified from natural stillborn foetuses. Phylogenetic analysis showed the two strains of PCV3 are 96% identical to the known PCV3/Pig/USA (KX778720.1, KX966193.1 and KX898030.1) and closely related to Barbel Circovirus. Further studies of the epidemiology of PCV3 and the co-infection with PCV2 are needed.
在中国山东检测到了猪圆环病毒3型(PCV3)。222份样本中有132份(59.46%)PCV3呈阳性,而132份样本中的52份(39.39%)与PCV2共同感染。经产母猪或活产仔猪均无感染的临床症状。从自然死胎中鉴定出两株PCV3。系统发育分析表明,这两株PCV3与已知的PCV3/猪/美国(KX778720.1、KX966193.1和KX898030.1)有96%的同源性,并且与鲤科环病毒密切相关。需要对PCV3的流行病学及其与PCV2的共同感染进行进一步研究。
