“…While not many studies have reported on isolation-based LAB data on the diversity and abundance from goats, the results are parallel to those reported in a recent study on lactic acid bacteria diversity in young piglets. In the latter study, the structure and predominant lactic acid bacteria changed significantly between birth and weaning [ 46 ].The current study findings also agree with the few studies that have detected Lactobacillus species as common inhabitants in the gut of ruminants including goats [ 47 ] and calves [ 48 ]. In the latter study involving young calves, L. johnsonni , L. salivarius , L. murinus , L. mucosae , L. amyolovorus and Enterococcus spp.…”

“…Genome analysis of L. reuteri isolated from goats in Mongolia indicated differences compared to isolates from cows, sheep and horse [ 47 ]. L. reuteri were also the most frequently detected LAB in pigs [ 41 , 54 ] including pre-weaned pigs [ 46 ]. The beneficial effects of L. reuteri include the production of antimicrobial molecules (organic acids, ethanol and reuterin) [ 55 ] and immunomodulatory effects [ 51 ].…”

Understanding gut lactic acid bacteria (LAB) in healthy hosts is an important first step in selecting potential probiotic species. To understand the dynamics of LAB in healthy goats, a cohort of thirty-seven healthy new-born goat kids was studied over a ten-month period. Total LAB was quantified using SYBR green qPCR. Seven hundred LAB isolates were characterized using microscopy, M13 RAPD genotyping and 16S rDNA sequencing. The highest and lowest LAB counts were detected at one week and ten months of age, respectively. Diverse LAB species were detected, whose identity and prevalence varied with age. The main isolates belonged to Limosilactobacillus reuteri, Limosilactibacillus fermentum, Lactobacillus johnsonni, Ligilactobacillus murinus, Ligilactobacillus salivarius, Limosilactobacillus mucosae, Lactiplantibacillus plantarum, Ligilactobacillus agilis, Lactobacillus acidophilus/amyolovolus, Pediococcus spp. and Enterococcus spp. Uniquely, L. reuteri and Pediococcus spp. were most common in pre- and peri-weaned goats, while Lactobacillus mucosae and Enterococcus spp. were predominant in goats one month and older. Based on RAPD genotyping, L. reuteri had the highest genotypic diversity, with age being a factor on the genotypes detected. This data may be relevant in the selection of age-specific probiotics for goats. The findings may also have broader implications by highlighting age as a factor for consideration in probiotic bacteria selection in other animal hosts.
