The growing importance of Enterococcus and Streptococcus Agalactiae in uncomplicated urinary tract infections

Background . Urinary tract infections (UTIs) represent 10-20% of all community-acquired infections. Escherichia coli remains the most commonly isolated microorganism. Because of the dominance of these bacteria, routine laboratory tests are not recommended in making the first UTI diagnosis. However, careful monitoring of all etiological agents of ncomplicated UTIs should be an important strategy for empirical therapy. Objectives . A determination of the incidence of UTI bacterial etiological agents in outpatients. Material and methods. The results of urine cultures were analyzed. The samples were obtained in the period from 01.2011 to 03.2013 from outpatients of all age groups. Results . The rods of Escherichia coli were the most frequently identified microorganisms responsible for uncomplicated UTIs. They were isolated from 52% of infected patients. Every fourth case of UTI indicated the participation of Enterococcus spp. And Streptococcus agalactiae . The next 21% of infections were caused by Gram-negative bacteria other than E. coli . The role of coagulase-negative staphylococci was insignificant and equaled less than 2%. Conclusions . Despite the dominant role of E. coli in urinary tract infections, there has been a decrease in the frequency of its isolation. However, the natural resistance of Enterococcus spp. to antibiotics increases the number of urinary tract infections caused by these bacteria. Streptococcus agalactiae is a UTI cause with similar frequency in women of reproductive age and postmenopausal women. Monitoring of the incidence of uncomplicated infections facilitates empirical treatment and prevents UTI recurrence

In Silico Screening and In Vitro Assessment of Natural Products with Anti-Virulence Activity against Helicobacter pylori

Helicobacter pylori is one of the most frequent human pathogens and a leading etiological agent of various gastric diseases. As stringent response, coordinated by a SpoT protein, seems to be crucial for the survivability of H. pylori, the main goal of this article was to use in silico computational studies to find phytochemical compounds capable of binding to the active site of SpoT from H. pylori and confirm the ability of the most active candidates to interfere with the virulence of this bacterium through in vitro experiments. From 791 natural substances submitted for the virtual screening procedure, 10 were chosen and followed for further in vitro examinations. Among these, dioscin showed the most interesting parameters (the lowest MIC, the highest anti-biofilm activity in static conditions, and a relatively low stimulation of morphological transition into coccoids). Therefore, in the last part, we extended the research with a number of further experiments and observed the ability of dioscin to significantly reduce the formation of H. pylori biofilm under Bioflux-generated flow conditions and its capacity for additive enhancement of the antibacterial activity of all three commonly used antibiotics (clarithromycin, metronidazole, and levofloxacin). Based on these results, we suggest that dioscin may be an interesting candidate for new therapies targeting H. pylori survivability and virulence

An efficient Nb-modified BiVO4 film for photo-induced bacterial inactivation and photocatalytic removal of organic pollutants

International audienceUsing a Nb-modified BiVO4 film, the photo-induced properties in Methicillin-resistant Staphylococcus aureus (MRSA) inactivation under simulated solar light reached 43% after 1 hour of irradiation, while 72% of Rhodamine B was degraded after 3 hours. To evaluate the efficiency of Nb-BiVO4, its photo-performance was compared with that of BiVO4/TiO2 composites and pure BiVO4

Antimicrobial O-Alkyl Derivatives of Naringenin and Their Oximes Against Multidrug-Resistant Bacteria

New antimicrobial agents are needed to address infections caused by multidrug-resistant bacteria. Here, we are reporting novel O-alkyl derivatives of naringenin and their oximes, including novel compounds with a naringenin core and O-hexyl chains, showing activity against clinical strains of clarithromycin-resistant Helicobacter pylori, vancomycin-resistant Enterococcus faecalis, methicillin-resistant Staphylococcus aureus, and beta-lactam-resistant Acinetobacter baumannii and Klebsiella pneumoniae. The minimum inhibitory concentrations (MICs), which provide a quantitative measure of antimicrobial activity, were in the low microgram range for the selected compounds. Checkerboard assays for the most active compounds in combination with antibiotics revealed interactions that varied from synergistic to neutral

Enterococcus in wound infections: Virulence and antimicrobial resistance

Enterococci, a complex group of facultative pathogens have become increasingly isolated in various hospital settings. They are considerable frequently cultured from traumatic and surgical wounds. We investigated 57 strains of the species E. faecalis, E. faecium and E. casseliflavus isolated from infected wounds. Their ability to produce virulence factors and their sensitivity to antibiotics were evaluated using phenotypic and genotyping methods. In the phenotype studies, significant portion of the isolates produced biofilm (66.7%) and gelatinase (36.8%). Nearly 30% of the strains expressed hemolytic properties. Only a few produced DNAse (15.8%) and lipase (7.0%). The genes esp, gelE, cylA, cylB, cylM and agg were detected in most of the isolates (38.6–87.7%). All the isolated enterococci were susceptible to vancomycin and were characterized by their low resistance to antibiotics, except aminoglycosides (HLR)
