广西部分地区猪细环病毒的分子流行病学调查
Molecular epidemiological investigation of Torque teno sus virus in part of Guangxi
摘要
Abstract
In order to know the prevalence and predominant genotype of Torque teno sus virus (TTSuV) found in recent years in Guangxi,95 blood and corresponding tissue samples(lymph node,spleen and lung) were collected from different pig farms in Guangxi and detected by a nested PCR method. Several positive samples were selected to clone and then sequenced. The results revealed that TTSuV infection was widespread in the detected pig population. The positive rates of TTSuVl and TTSuV2 like viruses were 37.9% and 20. 0% respectively, in which 11. 6% were co-infected. The nucleotide sequences of the 9 TTSuV1 fragments and 10 TTSuV2 fragments were 81. 8% to 99. 7% and 79. 2% to 99. 2% identities,respectively when compared to those of the reference strains available in NCBI. Phylogenetic analysis showed the epidemic strains of TTSuVs in Guangxi were TTSuV la,TTSuV 1b and TTSuV 2a.关键词
