Recent interest in coronavirus has stimulated further investigation into the antiviral attributes of Bacillus subtilis. Many studies have found antiviral properties including these listed below of interest to production animals:

Suid Herpes Virus (causing Pseudorabies or Aujeszky's disease – in pigs and other farm animals including sheep and goats).

Vesicular Stomatitis Virus (primarily affects cattle and horses and can affect sheep, goats, pigs, llamas and alpacas).

Newcastle Disease Virus (chickens)

Infectious Bursal Disease Virus (chickens)

Porcine Parvovirus (pigs)
