“…This is further supported by Olukosi et al (2017) , who found that reducing the exposure of the RSM to preliminary thermal treatments prior to solvent extraction and desolventising/toasting contributed to 1.3 MJ/kg greater ME in the final meal. Confirming previous findings, dietary XYL reduced FI ( Pirgozliev et al, 2015 ) and FCR ( Olukosi et al, 2020 ; Pirgozliev et al, 2021 ). The marginal improvement in growth performance variables in birds fed both enzymes agrees with the view that feeding a combination of enzymes can have a positive additive effect on growth performance of poultry ( Olukosi et al, 2010 ; Abdulla et al, 2017 ).…”

“…Stevia is mainly known as a natural sweetener, it is also gaining interest due to the many beneficial effects not only for humans (25,32,11), but also animals, where these herbs can serve as feed additives (having a supplementary role) or alternative feed source (11,4,5,27). It has also been shown, that phages can be used as feed additives to reduce bacteria in animal preslaughter, without negatively impacting microbial communities (40).…”

Introduction: In the light of the problem of antibiotic-resistance, the use of alternative combined therapies in combating bacterial-related issues has gained popularity. Therefore, using up-to-date laboratory techniques, possible interactions of lytic bacteriophages (MS2, T4 and Phi6), acetone and methanolS. rebaudianaextracts (SRa and SRm) in the bacterial environment have been examined. Material and Methods: Using a microdilution method, phages-extracts coincubation assay, static interactions synographies and dynamic growth profile experiments in a bioreactor, it was found that the interactions in a static environment differ from interactions in a dynamic environment. Results: Dynamic conditions alter the influence of extracts in a concentration-dependent manner. The effects of the SRa and SRm extracts on bacterial growth in a dynamic environment depend on the species of the phage and bacterial host. The greatest differences were observed forE. colistrains and their phages, whereas P. syringae and Phi6 phage reacted very similar to both extracts. The differences also emerged for single extracts withinE. colistrains and their phages. Conclusions: Every extract type should be tested on a case-by-case basis and experiments outcomes should not be generalized before gathering data. Moreover, many varied experiments should be performed, especially when examining such multifactorial mixtures. Tested mixtures could be potentially used in multi-drug resistant bacterial infections treatments.

Introduction In the light of the problem of antibiotic resistance, the use of combined alternative therapies in combatting bacteria-related disorders has gained popularity. Bacteriophages are one element implemented in new combination therapy. Stevia rebaudiana is known to have antimicrobial activity and regarded as potentially having a synergistic effect with bacteriophages. Therefore, possible interactions of lytic bacteriophages (MS2, T4 and Phi6) with acetone and methanol S. rebaudiana extracts (SRa and SRm) in the bacterial environment were examined. Material and Methods The interactions were tested using a microdilution method, phage-extract co-incubation assay, static interaction (synography) and dynamic growth profile experiments in a bioreactor. Results The interactions of the tested factors in a static environment differed from those in a dynamic environment. Dynamic conditions altered the effect of the extracts in a concentration-dependent manner. How different the effect of the SRa extract was to that of the SRm extract on bacterial growth in a dynamic environment depended on the species of the phage and bacterial host. The greatest differences were observed for E. coli strains and their phages, whereas Pseudomonas syringae and the Phi6 phage reacted very similarly to both extracts. Differences also emerged for the same extract in different E. coli strains and their phages. Conclusion Every extract type should be tested on a case-by-case basis and experiment outcomes should not be generalised before gathering data. Moreover, many varied experiments should be performed, especially when examining such multifactorial mixtures. The tested mixtures could potentially be used in multidrug-resistant bacterial infection treatments.
