Detection and evaluation of the antimicrobial activity of Micrococcin P1 isolated from commensal and environmental staphylococcal isolates against MRSA. Int J Antimicrob Agents 2023; 62:106965. [PMID: 37716578 DOI: 10.1016/j.ijantimicag.2023.106965] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 08/12/2023] [Accepted: 09/03/2023] [Indexed: 09/18/2023]
Abstract
BACKGROUND Bacteriocins (of different origins) have been proposed as promising alternatives to face antimicrobial resistance-associated health problems. Isolates of the Staphylococcus genus are well-known bacteriocin producers, especially coagulase-negative species. METHODS Twenty-eight bacteriocin-producing staphylococcal isolates were selected from a previous study for in-depth characterisation. The antimicrobial activities (AA) of the producing isolates were studied by the spot-on-lawn method and their crude cell-free supernatants (CFS) and butanol extracts (BT) were evaluated by agar diffusion assays against six indicator bacteria, including multidrug-resistant and zoonotic isolates (such as Listeria monocytogenes or methicillin-resistant Staphylococcus aureus [MRSA]). RESULTS Six bacteriocin-producing isolates showed AA in their CFS, whereas all staphylococcal BT extracts inhibited at least one of the tested indicator bacteria. Micrococcin P1 (MP1) bacteriocin was detected by mass spectrometry in four producing isolates: Staphylococcus aureus-C5802, Staphylococcus hominis-C5835, Staphylococcus sciuri-X3041, and -X3011. Growth curves performed with CFS and BT extracts of the four MP1 producers revealed a strong AA profile against MRSA and Listeria monocytogenes, even when considerably diluted. Moreover, synergism between the BT extract of MP1-producing Staphylococcus sciuri-X3041 and several antibiotics against an MRSA indicator was observed: BT-clindamycin (> 80%) and BT-oxacillin (30%) combinations. For the BT-chloramphenicol combination, synergism and near synergism values were observed in 37% of the combinations. Competition studies revealed potent inhibitory effects of the MP1-producing isolates against the MRSA indicator. CONCLUSION These results help to identify Staphylococcus isolates or their bacteriocins as interesting candidates for potential future applications.

Antimicrobial and Antibiofilm Activity of the Probiotic Strain Streptococcus salivarius K12 against Oral Potential Pathogens. Antibiotics (Basel) 2021; 10:antibiotics10070793. [PMID: 34209988 PMCID: PMC8300812 DOI: 10.3390/antibiotics10070793] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 06/25/2021] [Accepted: 06/25/2021] [Indexed: 12/19/2022] Open
Abstract
Oral probiotics are increasingly used in the harmonization of the oral microbiota in the prevention or therapy of various oral diseases. Investigation of the antimicrobial activity of the bacteriocinogenic strain Streptococcus salivarius K12 against oral pathogens shows promising results, not only in suppressing growth, but also in eliminating biofilm formation. Based on these findings, we decided to investigate the antimicrobial and antibiofilm activity of the neutralized cell-free supernatant (nCFS) of S. salivarius K12 at various concentrations against selected potential oral pathogens under in vitro conditions on polystyrene microtiter plates. The nCFS of S. salivarius K12 significantly reduced growth (p < 0.01) in Streptococcus mutans Clarke with increasing concentration from 15 to 60 mg/mL and also in Staphylococcus hominis 41/6 at a concentration of 60 mg/mL (p < 0.001). Biofilm formation significantly decreased (p < 0.001) in Schaalia odontolytica P10 at nCFS concentrations of 60 and 30 mg/mL. Biofilm inhibition (p < 0.001) was also observed in Enterobacter cloacae 4/2 at a concentration of 60 mg/mL. In Schaalia odontolytica P10 and Enterobacter cloacae 4/2, the nCFS had no effect on their growth.

Abstract
Kazachstania slooffiae is a fungus commonly isolated from the gastrointestinal tract and feces of post-weaning pigs. Studies have implicated its ability to positively alter piglet gut health through potential symbioses with beneficial bacteria, including Lactobacillus and Prevotella, in providing amino acids as an energy source for microbial and piglet growth, and it has been found to be positively correlated with short-chain fatty acids in the piglet gut. However, basic mycological information remains limited, hampering in vitro studies. In this study, we characterized the growth parameters, biofilm formation ability, susceptibility to antimicrobials, and genetic relatedness of K. slooffiae to other fungal isolates. Optimal fungal growth conditions were determined, no antifungal resistance was found against multiple classes of antifungal drugs (azoles, echinocandins, polyenes, or pyrimidine analogues), and dimorphic growth was observed. K. slooffiae produced biofilms that became more complex in the presence of Lactobacillus acidophilus supernatant, suggesting positive interactions with this bacterium in the gut, while Enterococcus faecalis supernatant decreased density, suggesting an antagonistic interaction. This study characterizes the in vitro growth conditions that are optimal for further studies of K. slooffiae, which is an important step in defining the role and interactions of K. slooffiae in the porcine gut environment.

Abstract
The increase of antibiotic resistance has become a problem. Probiotic bacteria play an important role in preventive/supportive medicine. Therefore, we examined the inhibitory effects of four different Lactobacillus species' (L. acidophilus-La, L. plantarum-Lp, L. fermentum-Lf and L. rhamnosus-Lr) cell-free supernatants (CFSs) on growth, adhesion, invasion, and biofilm formation of Staphylococcus aureus and effects of S. aureus, CFSs, and S. aureus-CFSs co-existence on human osteoblast (HOB) cell viability. Growth alterations were measured spectrophotometrically. Adhesive/invasive bacterial counts were detected by colony counting. Biofilm was evaluated using microtiter plate assay. The MTT assay was used for detection of HOB cell viability. The growth of MSSA significantly (P < 0.01) decreased in the presence of two CFSs (Lf and Lr) (P < 0.01); the growth of MRSA significantly (P < 0.05) reduced in the presence of La CFSs. All tested CFSs were found to reduce adhesion and invasion of MSSA (P < 0.0001). The adhesion of MRSA was enhanced (P < 0.0001) in the presence of all CFSs except La and the invasion of MRSA was decreased (P < 0.01) in the presence of Lr and Lf CFSs. All tested CFSs were shown to inhibit biofilm formation significantly (P < 0.0001). The reduction of S. aureus infected HOB cell viability and exposed to all CFSs except Lr that was found to be significant (P < 0.0001). The viability of HOB cell during co-incubation with MSSA and CFSs was shown to be decreased significantly. However co-existence of MRSA and CFSs did not alter HOB cell viability. These results suggested that lactobacilli as probiotics have low protective effects on MRSA-infected host cells.

Abstract
For the first time the poly-resistant strains of Gram-negative microorganisms were studied for the sensitivity to combined simultaneous and sequential influence of metabolic complexes of Lactobacillus rhamnosus GG and Saccharomyces boulardii, obtained by the author’s method without using the growth media, with antibiotics. The synergic activity of antibacterial preparations and metabolic complexes of L. rhamnosus GG and S. boulardii were studied using modified disk-diffusive method of Kirby-Bauer. During the sequential method of testing (at first the microorganisms were incubated with structural components and metabolites, then their sensitivity to the antibacterial preparations was determined), we observed increase in the diameters of the zones of growth inhibition of Pseudomonas aeruginosa PR to the typical antibiotics (gentamicin, amіcyl, ciprofloxacin, сefotaxime) and non-typical (lincomycin, levomycetin) depending on the tested combinations. Acinetobacter baumannii PR exhibited lower susceptibility: growth inhibition was seen for the combination with ciprofloxacin, сefotaxime, levomycetin. Susceptibility of Lelliottia amnigena (Enterobacter amnigenus) PR increased to levofloxacin, lincomycin. The zones of growth inhibition of Klebsiella pneumoniae PR increased to gentamicin, amіcyl, tetracycline, сeftriaxone. Maximum efficiency was determined during sequential combination of antibiotics with separate metabolic complexes of L. rhamnosus and S. boulardii, and also their combination (to 15.2, 20.2 and 15.4 mm respectively) compared with their simultaneous use (to 12.2, 15.2 and 13.0 mm respectively) for all the tested poly-resistant pathogens, regardless of the mechanism of action of antibacterial preparation. Metabolic complexes of L. rhamnosus GG and S. boulardii, due to increase in the susceptibility of microorganisms, can decrease the therapeutic concentration of antibiotic, slow the probability of the development of resistance of microorganisms, and are therefore promising candidates for developing “accompanying medications” to antibiotics and antimicrobial preparations of new generation.

Abstract
Bacteria grow on surfaces and form communities called biofilms. Bacterial adhesion and properties of the derived biofilms depend on, among others, the nature of the supporting substrate. Here, we report how the surface properties of the substrate affect the biofilm growth of probiotic Lactobacillus rhamnosus GG (LGG). Hydrophilic (OH), hydrophobic (CH3), and positively charged (NH3+) surfaces were obtained by the functionalization of a ZnSe crystal with alkanethiol self-assembled monolayers (SAM). The self-assembly of alkanethiols onto ZnSe was studied in situ using infrared spectroscopy in attenuated total reflection mode (ATR-FTIR). The organization of grafted SAMs was analyzed based on the results of ATR-FTIR, high-energy elastic backscattering spectrometry, and contact angle measurements. The kinetics and adhesion strength of LGG initial attachment as well as its physiological state on surfaces terminated by the different functional groups were assessed by the combination of ATR-FTIR, force measurements based on atomic force microscopy, and fluorescent staining of bacteria. The strength of interactions between LGG and the surface was strongly affected by the terminal group of the alkanethiol chain. The -NH3+ groups displayed the highest affinity with LGG at the first stage of interaction. The surface properties also played an important role when LGG biofilms were further grown in a nutritive medium for 24 h under flow conditions. Notably, the analysis of the infrared spectra recorded during the biofilm cultivation revealed differences in the kinetics of growth and in the polysaccharide features of the biofilm depending on the substrate functionality. LGG biofilm was stable only on the positively charged surface upon rinsing. Findings of this work clearly show that the adhesion features and the growth of LGG biofilms are substrate-dependent.

Abstract
The work presented here is the first to examine the impact of Lactobacillus rhamnosus GG ATCC 53103 and Saccharomyces boulardii metabolites obtained using the author`s method on the formation of biofilm forms of bacteria. The structural components of the probiotic microorganisms were obtained using the method of physical disintegration – low frequency ultrasound waves produced by a G3-109 generator. Metabolites were obtained by cultivating L. rhamnosus and S. boulardii in ultrasound disintegrates of lactobacteria and Saccharomycetes. The impact of biologically active substances on the formation of biofilm of Corynebacterium ulcerans tox+ 112, C. diphtheriae gravis tox+ 108, by antibiotic-resistant Pseudomonas aeruginosa PR, Klebsiella pneumoniae PR, Lelliottia amnigena (Enterobacter amnigenus) PR and P. aeruginosa AТСС 27853 reference strain was studied using the spectrophotometric method. For the first time, we proved that L. rhamnosus GG and S. boulardii metabolites and combinations of metabolites of Saccharomycetes and lactobacteria, obtained by cultivating primary producers in their disintegrates, damage preformed 24-hour biofilms of gram-positive and gram-negative bacteria. The representatives of Corynebacterium exhibited higher sensitivity to the filtrates of disintegrates and products of vital activity of lactobacteria and Saccharomycetes than gram-negative pathogens. High parameters of decrease in optical density of preformed biofilms of Corynebacterium and antibiotic-resistant gram-negative bacteria were observed under the influence of combination of L. rhamnosus GG and S. boulardii metabolites (by 1.3–2.6 times). However, the largest reduction of the optical density of the formed biofilm of all studied strains was observed under the influence of metabolites of lactobacteria (by 1.5–5.3 times). Biologically active substances of L. rhamnosus GG and S. boulardii obtained using the author’s method can be used as candidate preparations which could have a strong influence on the process of the formation of the biofilms and preformed biofilms, and also as a preparations of substitution/addition of therapeutic prescription.
