Chlamydia trachomatis is responsible for a widespread sexually transmitted infection. In men, it associated with wide clinical spectrum causing infertility. Furthermore, C. serovar E infection decreases motility and increases the number of non-viable sperm. No other effects have been reported on sperm despite crucial role DNA integrity function. The aim this study was to investigate apoptosis.Sperm from eight normozoospermic men were incubated increasing concentrations elementary bodies (EB)...
Legionella pneumophila is an organism of public health interest for its presence in water supply systems and other humid thermal habitats. In this study, ten cell-free supernatants produced by Lactobacillus strains were evaluated their ability to inhibit L. isolated from hot tap water. Production antimicrobial substances assessed agar well diffusion test on BCYE plates pre-inoculated with pneumophila. Cell-free (CFS) showed activity against all tested: rhamnosus salivarius the highest...
Juglans regia L. (common walnut) is a deciduous tree belonging to Juglandaceae family. Since ancient time, walnut was widely used in traditional medicine for its antioxidant, antidiabetic, antimicrobial, anti-inflammatory, anti-atherogenic and liver-protective effects. In this work, the antibacterial anti-biofilm activities of walnuts pellicle extract against coagulase-negative staphylococci were evaluated. Qualitative chemical analysis performed by thin layer chromatography. UPLC-Ms/Ms...
The difficulty to treat resistant strains-related hospital-acquired infections (HAIs) promoted the study of phytoextracts, known sources bioactive molecules. Accordingly, in present study, pharmacological activities Juglans regia (L.) pellicle extract (WPE) were investigated. antiviral effect was tested against Herpes simplex virus type 1 and 2, Poliovirus 1, Adenovirus Echovirus 9, Coxsackievirus B1 through plaque reduction assay. antibacterial antifungal evaluated medically important...
Lactobacillus strains dominate the vaginal habitat and they are associated with a lower risk of genital infections. In addition, contribute to conservation microbiota by producing postbiotic agents. Previous studies have shown that their predominance involves antimicrobial activity against urogenital pathologies. this context, probiotics may improve treatment outcomes. The aim study was evaluate probiotic properties lactobacilli origin using multidisciplinary approach. For purpose, safety...
Streptococcus salivarius 24SMBc is an oral probiotic with antimicrobial activity against the otopathogens pyogenes and pneumoniae. Clinical studies have reinforced its role in reducing recurrence of upper respiratory tract infections (URTIs) rebalancing nasal microbiota. In this study, for first time, we characterized by whole genome sequencing annotation; likewise, antagonistic vs. pneumoniae was evaluated vitro co-aggregation competitive adherence tests. The comprises 2,131,204 bps 1933...
Bifidobacterium spp. can produce cell-bound or released exopolysaccharide (EPS) that is a beneficial trait mediating commensal-host interactions. However differences in the physico-chemical characteristics of EPS produced by different strains are determinant adhesion ability and modulation immune response. The aim this study was to investigate vitro longum W11 intestinal epithelial cell-line HT-29, Scanning Electron Microscopy (SEM), chemical its using Thin-Layer Chromatography (TLC)...
Background: The key ingredients of e-cigarettes liquid are commonly propane-1,2-diol (also called propylene glycol) and propane-1,2,3-triol (vegetal glycerol) their antimicrobial effects already established. nicotine flavors which often present in e-liquids can interfere with the growth some microorganisms. Objective: effect combining these elements is unknown. aim study was to investigate possible liquids on bacterial presence or absence flavors. Methods: Susceptibilities pathogenic strains...
The study was carried out to clarify the correlation between Chlamydia pneumoniae infection and peripheral arterial disease (PAD). level of specific antibodies 133 consecutive patients suffering from PAD at 2nd stage Leriche's classification were compared with 60 healthy controls by using a commercial Micro-IF Test.A higher incidence serological evidence C. found in (106/133) than (6/60).These results are agreement other findings that measured atheromasic plaques. A strong cause-effect...
The role of bacterial infections, mainly Chlamydophila pneumoniae, on atherosclerotic processes as well the therapeutic utility additional antibiotic treatment is still an open question. In this study we compared serological profiles 160 patients (80 with peripheral arterial disease (PAD), diagnosed ankle/brachial index (ABI) ≤0.9 and 80 risk factors for cardiovascular - CVD) those healthy subjects, serum levels specific C. pneumoniae antibodies using microimmunofluorescence test. Our...
