Abstract

A total of 166 faecal specimens from diarrheic cattle were collected in China for detection of bovine kobuvirus (BKV) by reverse transcription PCR (RT-PCR) targeting the region a portion of the 3D nonstructural protein, with an amplicon size of 631 bp. The RNA corresponding to the BKV 3D region was detected in 34.9 % of faecal samples (58/166) in four major dairy-cattle-production areas in China, and sequence analysis based on the partial 3D sequences (35/58) indicated that the Chinese BKVs shared 88.9-96.2 % nucleotide sequence identity to BKV reference strains. Further phylogenetic analysis based on the complete VP1-encoding sequences (17/35) revealed that the Chinese BKVs shared 81-83.4 % nucleotide sequence identity to the U-1 strain, and these Chinese BKV strains, together with the U-1 strain, are apparently divided into four lineages, representing four genotypes of BKV, designated as A, B, C and D. Our results show that BKV infection is widely distributed, with high genetic diversity in China.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
