A bovine viral diarrhea virus (BVDV), GS5, of the BVDV-1a subgenotype was isolated from dairy cattle in Gansu Province, northwest China. Its near-full-length genome was determined to be closely related to an early Belgian BVDV-1a strain, WAX-N, but the relatedness to domestic strains is relatively low, indicating that different genetic evolution occurred between the viral strains in cattle in C...

This study aims to characterize the presence of virulence factors of enterotoxigenic Escherichia coli (ETEC) causing traveler's diarrhea. Among 52 ETEC isolates, the most common toxin type was STh, and the most frequent colonization factors (CFs) were CS21, CS6, and CS3. On the other hand, the nonclassical virulence factors EAST1 and EatA were frequently present.

In cytopathic bovine viral diarrhea virus genotype 1 (BVDV1) isolates, insertions are reported at position A (amino acid [aa] 1535) and position B (aa 1589). Insertions at position B predominate. In this survey it was found that in BVDV2, insertions at position A predominate. Possible reasons for this difference in relative frequency are discussed.

We sequenced the complete genome of noncytopathic bovine viral diarrhea virus (BVDV) type 2 strain CN10.2015.821. It belongs to the subgenotype 2a, and it was isolated from an immunotolerant and persistently infected calf identified during a serological investigation. The complete genome is composed of 12,273 nucleotides, organized as one open reading frame encoding 3,897 amino acids.

Bovine viral diarrhea virus (BVDV) subgenotype 1e was isolated for the first time in Slovenia in 2006. Here, we report the complete genome sequence of BVDV-1e, strain SLO/2407/2006. The published genome will increase our understanding of the molecular characteristics of the BVDV-1e strains circulating in Europe.
