“…The isolation of lactic acid bacteria from the swine and poultry faeces is a reflection of the strains of LAB on the intestinal tract of birds and swine. The Lactic acid bacterial isolates from this study is similar to the findings from study conducted by Lin et al [7] isolated Lactobacillus and Streptococcus from the intestinal tract of pigs. Also Shazali et al [6] reported Lactobacillus, Lactococcus among the lactic acid bacteria genera isolated from faeces samples of broiler.…”

“…Thus, various alternatives have been explored to replace antibiotics as growth promoters. Lactic acid bacteria are probiotics and have been embraced by many as alternative to chemical growth promoters in livestock animals [7]. Lactic acid bacteria could still serve as antibiotics resistant genes reservoir which might be transferred to pathogenic bacteria.…”

“…Lactic acid bacteria could still serve as antibiotics resistant genes reservoir which might be transferred to pathogenic bacteria. The presence of antibiotics resistant LAB in animal faeces is an indication that the intestinal LAB is carrying a resistant gene which might be passed to human through food chain [6,7,8]. Also, the search for green fertilizers has encouraged the use of animal faeces as fertilizers.…”

Aim: This study’s aim was to determine the antibiotics resistant profile of lactic acid bacteria isolated from poultry and swine faeces. Study design: Faecal samples from swine and birds were randomly collected from livestock and poultry farms located in Umuahia metropolis, Abia State. Place and duration of study: Department of microbiology, Michael Okpara University of Agriculture Umudike, between January 2019 to August 2019. Methodology: A total of 12 faecal samples, 6 each from swines and birds were examined for the presence of lactic acid bacteria using Deman Rogosa Sharpe agar supplemented with 0.3% CaCO3 (w/v). Isolates were identified based on their physiological and biochemical characteristics. Antibiotic susceptibility was carried out using disk diffusion method. Results: Of the 12 faecal samples examined, all were positive for lactic acid bacteria, with counts ranging from 1.74 – 2.36 x 106 in swine and 1.52 – 2.08 x 106 in birds. Total of 14 strains that belong to three genera; Lactobacillus, Lactococcus and Streptococcus were isolated, genus Lactobacillus occurred highest 8(57.1%). The isolates showed multidrug resistance and exhibited high rate of resistance to Augmentin (100%), Ceftazidime (100%), Cefotaxime (92.9%), Erythromycin (85.7%), Ceftriaxone (71.4%) and Azithromycin (71.4%). Conclusion: The antibiotic resistance pattern of the isolated lactic acid bacteria is a clear indication that most animal farmers are misusing antibiotics. Therefore, animal farmers should be advised on antibiotic application safety measures.

“…Selected strains P7 and P16 were identified as L. reuteri, and P15 and P8 as L. johnsonii and L. amylovorus, respectively. L. reuteri is a naturally occurring microbiota in the intestinal tract of animals; it can produce bacteriocins to inhibit the growth of intestinal pathogenic bacteria, and at the same time has the ability of adhesion, colonizing in the intestinal tract and competing with pathogenic bacteria for adhesion sites of intestinal epithelial cells, thus reducing the risk of invasion by pathogenic bacteria [39]. L. johnsonii has good probiotic effects, which can improve the growth performance of dogs, and reduce the colonization of pathogenic bacteria [40].…”

Enterotoxigenic Escherichia coli (ETEC), which expresses K88 is the principal microorganism responsible for bacterial diarrhea in pig husbandry, and the indiscriminate use of antibiotics has caused many problems; therefore, antibiotics need to be replaced in order to prevent diarrhea caused by ETEC K88. The objective of this study was to screen excellent lactic acid bacteria (LAB) strains that inhibit ETEC K88 and explore their effects as probiotic supplementation on reproduction, growth performance, diarrheal incidence, and antioxidant capacity of serum in sows and weaned piglets. Three LAB strains, P7, P8, and P15, screened from 295 LAB strains and assigned to Lactobacillus (L.) reuteri, L. amylovorus, and L. johnsonii with high inhibitory activity against ETEC K88 were selected for a study on feeding of sows and weaned piglets. These strains were chosen for their good physiological and biochemical characteristics, excellent exopolysaccharide (EPS) production capacity, hydrophobicity, auto-aggregation ability, survival in gastrointestinal (GI) fluids, lack of hemolytic activity, and broad-spectrum activity against a wide range of microorganisms. The results indicate that LAB strains P7, P8, and P15 had significant effects on improving the reproductive performance of sows and the growth performance of weaned piglets, increasing the activity of antioxidant enzymes and immune indexes in both.

“…The antibacterial activity against pathogenic bacteria was categorized into 6 standards. The diameter of the inhibition zone was classified as < 10 mm, none (−); > 10 mm, weak (+); > 15 mm, middle (+ +); > 20 mm, strong (+ + +); or > 25 mm, very strong (+ + + +) inhibition (Lin et al, 2020).…”
