Summary

Streptococci capable of fermenting lactose and starch have been isolated from the large colon contents of fistulated ponies.

They form a capsule which is easily demonstrated by the capsular swelling reaction described by Neufeld.

They can be differentiated serologically from other types of streptococci.

The colon also, contains the Gram-negative coccus Veillonella gazogenes, an anxroblc fermenter of lactate.

  • Impact of diet on bacterial lipopolysaccharides in equine feces and blood

    2018, Livestock Science
    Citation Excerpt :

    In equine, the amylolytic bacteria identified so far in the hindgut belong to the Streptococcaceae and the Lactobacillaceae families (Kern et al., 1973; Maczulak et al., 1985; Al Jassim et al., 2005), but these two families contain only gram-positive bacteria species. Among the lactate-utilizing bacteria, species identified in equine hindgut belong to the gram-negative Veillonellaceae family (Alexander et al., 1952; Alexander and Davies, 1963). These latter have probably contributed to increase of LPS concentration.

  • The Impact of Diet on the Hindgut Microbiome

    2017, Journal of Equine Veterinary Science
    Citation Excerpt :

    The major lactate-utilizing bacteria belong to the Veillonellaceae families and to the Megasphaera and Veillonella genera. Peptostreptococcus elsdenii (now Megasphaera elsdenii) and Veillonella gazogenes (now Veillonella alcalescens) were identified early on as main lactate-utilizing bacteria species in the hindgut [18,20]. The global VFA composition within the hindgut content is determined by the microbiota composition and by the nature of plant carbohydrates in the digesta.
