Abstract

Lactic acid bacteria (LAB) are beneficial microorganisms present in the bovine vagina. Documentation of LAB community in the vagina of indigenous and cross bred dairy cows of India is important to further establish its probiotic potential. The aim of this study was to isolate and identify the spectrum of LAB by phenotypic and genotypic methods. A total of 24 LAB were isolated from the vagina of 110 apparently healthy indigenous and cross bred cows. The LAB isolates belonged to the genus Lactobacillus, Bacillus, Enterococcus and Weisella and were further speciated based on their grouping with respective reference sequences available in the GenBank, on phylogenetic analysis. The species diversity of bovine vaginal LAB identified in this study was Lactobacillus agilis (17%), Lactobacillus mucosae (8%), Lactobacillus plantarum (21%), Lactobacillus fermentum (17%), Lactobacillus pentosus (4%), Weisella cibaria (8%), Bacillus coagulans (4%), Bacillus cereus (4%), Enterococcus faecium (13%) and Enterococcus asini (4%). The overall spectrum and relative abundance of the bovine vaginal LAB reported in this study provides critical information for the formulation of uterine probiotics for the prevention/treatment of bovine clinical endometritis.

印度本土奶牛和杂交奶牛的阴道乳酸菌谱

乳酸菌（LAB）是存在于牛阴道中的有益微生物。记录印度本土奶牛和杂交奶牛阴道中的 LAB 群落对进一步确定其益生菌潜力非常重要。本研究旨在通过表型和基因型方法分离和鉴定 LAB 菌群。研究人员从 110 头表面健康的本土奶牛和杂交奶牛的阴道中分离出 24 种 LAB。分离出的 LAB 属于乳酸杆菌属、芽孢杆菌属、肠球菌属和魏氏菌属，并根据它们与 GenBank 中相应参考序列的分组和系统发育分析进行了进一步的分类。本研究鉴定的牛阴道 LAB 的物种多样性为：农业乳杆菌（17%）、粘液乳杆菌（8%）、植物乳杆菌（21%）、发酵乳杆菌（20%）、肠球菌（20%）和魏氏菌（20%）、发酵乳杆菌（17%）、戊糖乳杆菌（4%）、西巴氏魏氏菌（8%）、凝结芽孢杆菌（4%）、蜡样芽孢杆菌（4%）、粪肠球菌（13%）和阿斯尼肠球菌（4%）。本研究中报告的牛阴道 LAB 的总体谱系和相对丰度为配制子宫益生菌预防/治疗牛临床子宫内膜炎提供了重要信息。

期刊介绍： Traditional knowledge" is employed to mean knowledge, innovations and practices of indigenous and local communities embodying traditional life-styles; the wisdom developed over many generations of holistic traditional scientific utilization of the lands, natural resources, and environment. It is generally passed down by word of mouth, from generation to generation and is, for the most part, undocumented. Traditional knowledge is valid and necessary, and awaits its currently relevant wider application for human benefit. National Institute of Science Communication and Information Resources, CSIR felt a need to document the recent developments and the information bygone in this area in the form of an interdisciplinary periodical. The Indian Journal of Traditional Knowledge will carry original research papers, review articles, short communications, etc. concerned with the observation and experimental investigation of the biological activities of the materials from plants, animals and minerals, used in the traditional health-care systems such as Ayurveda, Siddha, Yoga, Unani, Naturopathy, Homoeopathy, Folk-remedies, etc. As validation of indigenous claims it will cover Ethno-biology, Ethno-medicine, Ethno-pharmacology, Ethno-pharmacognosy & Clinical Studies on efficacy .
