Key result

BEV and BEV-like sequences were detected in 67% of cattle, 24% of goats, and 10% of gaurs, with phylogenetic analysis showing co-circulation of EV-E and EV-F species in cattle.

Population

Fecal samples from domestic cattle, domestic goats, Indian bison/gaurs, and deer in Thailand.

Design

Preclinical

Implication

Suggests livestock as enterovirus reservoirs; leaves open human myocarditis risk.

Study Design

Type

Cross-Sectional (n=184)

Structured PICO

P
Population
184 fecal samples from cattle, goats, gaurs, and deer in Thailand were screened to assess the prevalence and genetic variability of bovine enteroviruses.
E
Exposure
Detection of BEV 5'UTR using nested RT-PCR and phylogenetic analysis
O
Outcome
Presence and genetic variability of BEV and BEV-like 5'UTR sequences

This study demonstrates the presence and genetic diversity of bovine enteroviruses in domestic and wild animals in Thailand, highlighting host-specific clustering and co-circulation of variants.

Limitations

  • Short length of the initial sequences analyzed (158-162 nt) resulted in low bootstrap values, limiting species classification.
  • Analyses of capsid and polymerase genes are required to definitively confirm the species and serotypes/genotypes of the circulating BEV.
  • Original sources of the cattle were unknown, preventing conclusions about transmission routes among herds.
  • Short length of sequences analyzed initially (158-162 nt) led to low bootstrap values for EV-E/EV-F separation

Cite This Study

Kosoltanapiwat et al. (2016) conducted a cross-sectional in Bovine enterovirus (BEV) infection (n=184). Animal species (cattle, goats, gaurs, deer) was evaluated on Detection of BEV and BEV-like 5'UTR sequences in fecal samples. BEV and BEV-like sequences were detected in 67% of cattle, 24% of goats, and 10% of gaurs, with phylogenetic analysis showing co-circulation of EV-E and EV-F species in cattle.
