objective(s):urinary tract infection (uti) caused by bacteria is one of the most frequent infections in human population. inappropriate use of antibiotics, often leads to appearance of drug resistance in bacteria. however, use of probiotic bacteria has been suggested as a partial replacement. this study was aimed to assess the antagonistic effects of lactobacillus standard strains against bacte...

The main objective of this study is removal of pathogenic bacteria using electrochemical process. The bactericidal effects of electrochemical system containing steel mesh electrode were evaluated from contaminated water with E. coli, Pseudomonas aeroginosa, Staphylococcus aureous and Streptococcus fecalis at various concentrations. Effect of current density, supporting electrolyte and pathogeni...

This study investigated the bacteriological and physicochemical quality of seawater sediment samples collected from four sampling sites in Gulf Annaba (Northeastern Algeria) over a one-year period. Culture-based techniques were used to quantify assess Fecal Indicator Bacteria (FIB) potentially pathogenic bacteria. Additionally, various parameters including temperature, pH, salinity, dissolved o...

screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. actinomycetes have the capability to synthesize manydifferent antibiotics. a total of 69 actinomycete isolates were recovered from soil samplescollected from alborz province. selected colonies (rough, chalky) of actinomycetes werepurified. all screened isolates were iden...

background considering the high prevalence of bacterial vaginosis and its association with urinary tract infection in women and treatment of gynecologic problems occur when a high recurrence of bacterial vaginosis is often treated with antibiotics. objectives the purpose of this study was to investigate the inhibitory effect of lactobacillus reuteri on pathogenic bacteria isolated from women wi...

Background: Microbial biofilms are responsible for many human infections and increase of antibiotic resistant bacteria. Therefore, finding an efficient way to prevent infection and biofilm formation of bacteria is essential. Medicinal plants are among suitable candidates to inhibit biofilm formation of bacteria. The aim of this study was to evaluate the antimicrobial effects of...

we investigated the microbiological quality of raw vegetables in mashhad, iran. in order to document the incidence of indicator and pathogenic microorganisms in this area. ninety eghit raw vegetable samples collected during 7 months were analyzed. all samples were examined for the presence of aerobic mesophilic bacteria, coliforms, enterobacteriaceae, escherichia coli, escherichia coli o157:h7,...

conclusions these human-derived lab and bifidobacteria exhibited different mechanisms involved in pathogenic inhibition. therefore a combination of these probiotic strains could be a great promise and possibility for the development of probiotic products to effectively prevent and control food-borne infection in humans. background food-borne pathogens are among the most significant problems in ...
