According to De Graef et al. 2003, Enterococcus villorum Vancanneyt et al. 2001 is an earlier heterotypic synonym of Enterococcus
porcinus Teixeira et al. 2001.

Gram-positive cocci, non-spore-forming and non-motile.
Colonies grow on azide-containing enterococcal selective media, on bile-aesculin
agar and in 6.5% NaCl broth. Colonies on Slanetz-Bartley medium are pink and
develop slowly. Alpha-haemolytic. Growth is positive at 10 - 45 °C.

Isolated from the intestines and faeces of pigs with diarrhoea and from birds. Susceptible to tobramycin. E. porcinus strains
were susceptible to vancomycin and efrotomycin.
