“…For probiotics, their uses have been shown to prevent occurrence of microbiological contamination while improving performances. However, effectiveness may depend on the type of probiotics used as well as internal and external factors [ 18 ].…”

Microbial Contamination of Chicken Litter Manure and Antimicrobial Resistance Threat in an Urban Area Setting in Cameroon

et al. 2020

We conducted a pilot study to assess microbiological safety of chicken litter, an affordable organic and main fertilizer used in Cameroon and worldwide. A convenience sampling of 26 farms was done and a questionnaire was administered. Samples of litter were aseptically collected. E. coli and Salmonella spp. were isolated using CLSI standards. Antibiotic susceptibility testing was performed using the disc diffusion method and a micro broth dilution method for colistin. In broiler farms, 90% of participating farmers gave antibiotic prophylaxis. The prevalence of E. coli and Salmonella spp. was 59.1% and 15.5%, respectively. All E. coli isolates were multidrug resistant as well as 36.4% for Salmonella spp. No resistance was found against cefepime and imipenem. All Salmonella spp. tested were found sensitive to colistin while 26.7% of E. coli spp. were colistin resistant. Contamination of chicken litter may be an underestimated source of antimicrobial resistance (AMR) transmission towards animals, humans and the environment with multidrug resistant E. coli and Salmonella spp. This shows the need and opportunity for a One Health approach in AMR surveillance and control in Cameroon. Continued surveillance in chicken litter would enable monitoring of AMR risks and trends.

“…Despite the numerous alternatives that have been evaluated to replace antibiotics in the modern poultry industry, the group of probiotics has shown promising results ( 2 ). Despite the success of the lactic acid bacteria (LAB) probiotic for use in commercial poultry, there is still a pressing need for shelf-stable, cost-effective, and feed-stable (tolerance to the heat pelletization process) commercial probiotics to increase compliance and widespread use ( 3 ).…”

Whole-Genome Sequence and Interaction Analysis in the Production of Six Enzymes From the Three Bacillus Strains Present in a Commercial Direct-Fed Microbial (Norum™) Using a Bliss Independence Test

The three Bacillus strains present in Norum™ were initially selected by their excellent to good relative enzyme activity (REA) production score for amylase, protease, lipase, phytase, cellulase, β-glucanase, and xylanase. Further studies confirmed that the three isolates also showed an antibacterial activity, Gram-positive and Gram-negative poultry pathogens. Norum™ (Eco-Bio/Euxxis Bioscience LLC) is a Bacillus spore direct-fed microbial (DFM). The Bacillus isolates were screened and selected based on in vitro enzyme production profiles. Moreover, in chickens fed high non-starch polysaccharides, this DFM demonstrated to reduce digesta viscosity, bacterial translocation, increase performance, bone mineralization, and balance the intestinal microbiota. In the present study, we present the whole-genome sequence of each of the three isolates in Norum™, as well as the synergistic, additive, or antagonistic effects on the enzyme production behavior of the three Bacillus strains and their combinations when grown together vs. when grown individually. The whole-genome sequence identified isolate AM1002 as Bacillus subtilis (isolate 1), isolate AM0938 as Bacillus amyloliquefaciens (isolate 2), and isolate JD17 as Bacillus licheniformis (isolate 3). The three Bacillus isolates used in the present study produce different enzymes (xylanase, cellulase, phytase, lipase, protease, and β-glucanase). However, this production was modified when two or more Bacillus strains were combined, suggesting possible synergistic, antagonistic, or additive interactions. The Bliss analysis suggested (p < 0.05) that the combination of Bacillus strains 1–2 and 1–2–3 had intermediate effects and predicted that the combination of Bacillus strains 2–3 could have better effects than the combination of all the three Bacillus strains. In summary, the current study demonstrated the need of selecting Bacillus strains based on quantitative enzyme determination and data analysis to assess the impacts of combinations to avoid antagonistic interactions that could limit treatment efficacy. These results suggest that using Bacillus strains 2–3 together could lead to a new generation of DFMs with effects superior to those already examined in Bacillus strains 1–2–3 and, therefore, a potential alternative to growth-promoting antibiotics. More research utilizing poultry models is being considered to confirm and expand the existing findings.

“…An example is the growing supply of probiotics. Probiotics are defined as "live strains of strictly selected microorganisms that, when administered in sufficient quantities, benefit the health of the body" (Hernandez-Patlan et al, 2019). It is worth noting that many types of lactic acid bacteria have the GRAS (Generally Recognised as Safe) status established by the US Food and Drug Administration (FDA), and the Qualified Presumption of Safety (QPS) status established by the European Food Safety Authority EFSA (Ovcharova & Petrakov, 2018).…”

Fermented camel milk as a probiotics source for poultry farming

et al. 2022

View full text Add to dashboard Cite

Currently, antibiotics are increasingly becoming the object of close attention due to the potential development of antibioticresistant pathogens after prolonged use, the use of antimicrobials also seriously pollutes the environment and destroys the ecological balance of nature. Feed antibiotics have been banned in the EU since 2006, and there is an active discussion of draft laws in this area in Russia. The poultry industry ranks second in the world in terms of output, so it is important to ensure the health of livestock and product safety. Since the purpose of this study is to investigate the effectiveness of the use of lactic acid bacteria (LAB) strains isolated from shubat (fermented camel milk) for the tasks and problems of the poultry industry, the theoretical basis of the study includes the analysis of research papers and statistical reports on the problems of the industry, the use of antibiotics in animal husbandry, and lactic acid bacteria as possible alternatives. The final part is devoted to the analysis of the practical studies results comparing different types of milk, their microbiological composition, and the advantages of shubat for the probiotics production for poultry. Due to the peculiarities of camel milk and the "ethnicity" of shubat, quantitative and qualitative data of isolated microorganisms from these products have advantages over other species.
