La diversité de l’écosystème microbien du tractus digestif équin

Abstract: Le gros intestin (caecum et côlon) des équins héberge un microbiote abondant et divers dont une fonction essentielle est la dégradation et la fermentation des parois végétales ingérées en produits directement utilisables par l’hôte. Ce microbiote est composé de cinq grandes communautés microbiennes (protozoaires, bactéries, champignons, Archaea et virus) parmi lesquelles les bactéries ont été les plus étudiées. Ces communautés sont spécifiques de l’espèce équine. La diversité des protozoaires comme celle des c… Show more

“…Butyrivibrio sp. bacteria were also identified as main components of equine gastrointestinal compartments . This would appear to suggest that a small part of ingested C18:3 n ‐3 may have been biohydrogenated by these bacteria to C18:1 t11, which could have been desaturated to CLAc9t11 in the mammary gland.…”

“…These bacteria are also the main cellulolytic bacteria in the equine gastrointestinal compartments. Similarly, Megaspheraelsdenii and Streptococcus bovis , which are among the main amylolitic bacteria of the cow's rumen, are also important components of the gastrointestinal flora of equine . Streptococcus bovis also plays a proteolytic role in the rumen .…”

“…One of the major concerns in the production of horses is the disruptions of the composition and/or activity of hindgut microbiota that lead to altered digestive health and onset of colic (Sadet‐Bourgeteau and Julliand ). The digestive system of the horse has a faster passage rate, leaving the microflora of the large intestine with less time to carry out fermentation, this leads to accumulation of lactate and reduction in pH leading to subclinical acidosis in the caecum‐colon, consequently increasing the horses’ susceptibility to colic pain or laminitis (Jouany et al ; de Rezende et al ).…”
