Unknown. It is possible to be involved in the production of catarrhal enteritis in calf.
Phylum Firmicutes, Class Bacilli, Order Lactobacillales, Family Streptococcaceae, Genus Streptococcus, Streptococcus entericus
Vela et al. 2002. Lancefield group D.
Gram-positive cocci, non-motile, grouped in short chains.
Colonies are nonpigmented, circular, 1 mm in diameter and alpha-hemolytic after 24
hours incubation on blood agar.
Growth temperature 37 ºC, not at 10 or 45 ºC. Facultatively anaerobic. Growth occurs
at pH 9.6 but not in broth containing 6.5% NaCl. Bile-aesculin test is negative.
Isolated from faeces and jejunum of a calf with enteritis. Unknown habitat. Sensitive to vancomycin.
