摘要

我们研究了口服乳酸菌胶囊对泌乳牛肠道菌群的影响。3 × 10¹¹菌落形成单位(cfu)冻干棒状乳杆菌亚种。torquens (JCM1099)包封在能够绕过瘤胃的肠胶囊中，给药7天。每天给药后0和24小时从粪便中提取DNA。宏基因组分析表明，物种多样性指标α多样性呈增加趋势。此外，肠道菌群主成分分析表明，JCM1099胶囊和混悬液可以通过主成分1、2和3来区分牛。由此可见，胶囊化的JCM1099可改变牛肠道菌群。

The effects of administering lactic acid bacteria sealed in a capsule on the intestinal bacterial flora of cattle.

We examined the effects of encapsulated lactic acid bacteria administrated orally to lactating cattle on the intestinal flora. A dose of 3 X 10¹¹ colony forming unit (cfu) of freeze-dried Lactobacillus coryniformis subsp. torquens (JCM1099) encapsulated in an enteric capsule capable of bypassing the rumen was administered for seven days. DNA was extracted from feces 0 and 24 hr after daily administration. Metagenomic analysis showed an increasing trend of the alpha diversity, an index of the species diversity. Furthermore, principal component analysis of intestinal flora revealed that cattle could be differentiated by JCM1099 capsule and suspension administration via principal components 1, 2, and 3. We conclude that administration of encapsulated JCM1099 can alter the intestinal bacterial flora of cattle.

期刊介绍： The Japanese Journal of Veterinary Research (JJVR) quarterly publishes peer-reviewed articles on all aspects of veterinary science. JJVR was originally published as a “University Journal” of veterinary science at Hokkaido University from more than 60 years ago. Currently, JJVR, is Japan’s leading scientific veterinary journal, and provides valuable information for the development of veterinary science by welcoming contributions from researchers worldwide. JJVR offers online submission for Regular Papers, Short Communications, and Review Articles that are unpublished and not being considered for publication elsewhere. Research areas include: Anatomy, Physiology, Biochemistry, Pharmacology, Microbiology, Infectious diseases, Parasitology, Laboratory Animal Science and Medicine, Internal Medicine, Surgery, Pathology, Theriogenology, Molecular Medicine, Public Health, Radiation Biology, Toxicology, Wildlife Biology and Medicine, Veterinary Hygiene, The other fields related to veterinary science.
