Active clinical trials for "Bacterial Infections"

This prospective case-control study was planned to evaluate the efficacy of antibiotic therapy selected with the AtbFinder® in persons with cystic fibrosis.

Background: The incidence of gastrointestinal infections is very high. In Western countries at least 30% of the population suffers from at least one food-borne infection per year. Mostly because of the problem of antibiotic resistance, more emphasis is put on prevention of infections. One of the possibilities is to strengthen human resistance to gut infections by consumption of probiotics. A specific blend of probiotic lactic acid bacteria (Lactobacillus helveticus Rosell-52, Lactobacillus rhamnosus Rosell-11, Bifidobacterium longum Rosell-175) and a probiotic yeast (Saccharomyces boulardii), improved stool consistency and shortened the duration of diarrhea in a rat model of E.coli-induced diarrhea. These probiotics showed synergistic effects compared with administration of solely S. boulardii or a mixture of L. helveticus Rosell-52, L. rhamnosus Rosell-11, B. longum Rosell-175. Consumption of S. boulardii and a combination of L. helveticus Rosell-52, L. rhamnosus Rosell-11 reduced diarrhea in humans. Aim: To study whether probiotics improves the resistance of humans to enterotoxigenic E. coli (ETEC). Study design: The PROTETEC study is a parallel, double-blind, placebo-controlled 4-weeks intervention with probiotics in healthy volunteers. In this study, the effect of probiotic intervention vs placebo on several infection markers in response to an ETEC challenge is investigated. Participants will be randomly assigned to the probiotic or placebo group (n=30 per group). Subjects will be instructed to maintain their usual pattern of physical activity and their habitual food intake, but to standardize their dietary calcium intake. After an adaptation period of 2 weeks, subjects will be orally infected with a live, but attenuated, ETEC vaccine (strain E1392-75-2A; collection NIZO food research; dose 10E10 CFU). Before and after infection, a diary will be kept to record all food and drinks consumption (2x2 days) to assess the habitual dietary intake, as well as for daily recording of bowel habits and frequency and severity of gastrointestinal complaints. The following biological samples will be collected: 4x10 ml venous blood, a single fecal bolus (for screening) and 7x24 hrs feces. Blood is sampled for immune response analyses and the fecal samples are collected to quantify several infection- and immune system markers, to determine probiotic excretion, and to verify dietary calcium intake. Study population: Healthy males of 20-55 yrs of age. Interventions: Probiotics (capsules containing freeze-dried powder, probiotic dose per capsule 5x10E9 CFU; twice daily) or placebo (capsules with carrier material powder of identical appearance) Primary outcomes: Fecal ETEC excretion and severity of diarrhea (quantified by fecal output per day). Secondary outcomes: Serum immune response to ETEC, self-reported stool consistency scores and gastrointestinal complaints, relative fecal wet weight. Tertiary outcomes: sIgA and calprotectin in feces, probiotic persistence and levels of opportunistic pathogens in the endogenous microbiota.

Primary Series Primary objectives To demonstrate that the concomitant administration of the hexavalent vaccine with a meningococcal serogroup C conjugate vaccine is non inferior to the administration of the hexavalent vaccine without a MenC vaccine concomitantly in term of seroprotection rate for hepatitis B one month after the third dose of the hexavalent vaccine To demonstrate that the concomitant administration of a MenC vaccine with the hexavalent vaccine induces an acceptable response for MenC in term of seroprotection rate (SPR) one month after the second dose of MenC Booster Primary objectives - To describe the immunogenicity of a booster dose of the hexavalent vaccine and of a meningococcal group ACWY conjugate (MenACWY) vaccine either co-administered at 12 months of age or given separately.

Background: The incidence of gastrointestinal infections is very high. In European countries 10-25% of the population suffers from at least one foodborne infection per year. Probiotics may strengthen human resistance to gut infections as they may beneficially modulate the intestinal microbiota composition and activity, and the immune function upon intestinal infection. Aim: To study whether probiotics improve the resistance of humans to enterotoxigenic E. coli (ETEC). Study design: The PRETEC study is a parallel, double-blind, placebo-controled 4-weeks intervention with probiotics in healthy volunteers. In this study, the effect of probiotic intervention vs placebo on several infection markers in response to an ETEC challenge is investigated. Participants will be randomly assigned to the probiotic or placebo group (n=21 per group). Subjects will be instructed to maintain their habitual food intake, but to standardize their dietary calcium intake. After an adaptation period of 2 weeks, subjects will be orally infected with a live, but attenuated, ETEC vaccine (strain E1392-75-2A; collection NIZO food research; dose will be 10E10 CFU). This ETEC strain induces mild and short-lived infectious diarrhea symptoms. Before and after infection, a diary will be kept to write down all food and drinks consumption (2x2 days) to assess the habitual dietary intake. The diary will also be used for daily recording of bowel habits and frequency and severity of gastrointestinal complaints. Blood is sampled for immune response analyses and multiple faecal samples are collected to quantify several infection- and immune system markers, to determine probiotic excretion, and to verify dietary calcium intake. Study population: Healthy males of 20-55 yrs of age. Interventions: Probiotics (freeze-dried powder, dose 10E9 CFU twice daily) or placebo (carrier material powder of identical appearance). Primary outcomes: Total fecal ETEC excretion per day and severity of diarrhea (quantified by faecal output per day). Secondary outcomes: Serum immune response to ETEC, self-reported stool consistency scores and gastrointestinal complaints, relative faecal wet weight, sIgA and calprotectin in faeces, probiotic persistence and levels of opportunistic pathogens in the endogenous microbiota.

The purpose of this study is to evaluate the effectiveness(immunogenicity) and safety of 'GC1107' administered intramuscularly in healthy children

This study will determine whether participants who receive V419 (PR5I) at 2, 4, and 11 to 12 months of age have an acceptable response to the vaccine. This study will also determine whether the immune response to V419 is similar to that of participants who received a licensed vaccine control. The primary hypothesis is that participants who receive PR5I at 2, 4, and 11 to 12 months have an acceptable response rate to all PR5I-contained antigens at one month after the Toddler dose of PR5I.

The primary purpose of this clinical trial is to compare in a double-blind randomized trial, the efficacy and safety of ciprofloxacin MR 1000 mg tablets given as a single-dose or as a multiple-dose regimen for the prevention of infectious complications in patients undergoing transrectal needle biopsies of the prostate (TRNBP).

Bloodborne pathogens are infectious bacteria, viruses, or other disease-causing germs carried in blood or other body fluids. These germs include hepatitis B and C viruses and HIV. Surgical and examination gloves are worn by health care workers to reduce the risk of workers catching germs from patients or patients catching germs from workers. The purpose of this study is to further develop polyvinylidene fluoride coatings for use as a protective coating worn underneath the gloves. Some health care workers may have tiny cuts on their hands that need to be protected, and gloves can have defects such as tiny holes that can allow germs to travel through them. The undercoating can add an additional layer of protection under gloves. The coating is applied in liquid form to hands and dries as a film without wrinkling, tearing, lifting, or bubbling. The liquid contains chemicals that fight germs. The coating also provides protection from skin irritation caused by the latex in some gloves.

Periprosthetic infection following shoulder arthroplasty is a devastating complication. Diagnosing and treating periprosthetic shoulder infection poses a significant challenge. At the forefront of this issue is Cutibacterium acnes because the current prophylactic regimens are insufficient to eradicate C acnes from the surgical field. It is believed that C acnes infections occur during surgery when the sebaceous glands in the skin are cut and exposed, leading to C acnes contaminating the surgeon's instruments and gloves and, thus, the surgical wound. The purpose of this study is to examine if making skin incisions using electrocautery will result in decreased C acnes contamination during shoulder arthroplasty. To this end, we propose a randomized clinical trial where patients undergoing shoulder arthroplasty are randomized into two groups - Electrocautery incision group (Electro) vs. Scalpel incision group (Scalpel) - and swab cultures are obtained from the skin incision and operating surgeon's gloves and forceps

The purpose of this study is to examine whether oral taking Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 from 28th week of gestation can reduce the GBS colonization rate of vagina and rectum in 35-37 weeks pregnant women as well as during laboring who present with GBS-positive at 28 weeks pregnancy. Through the results of our study, we try to investigate the role of probiotics in preventing the unnecessary tests, admission and antibiotic treatment in newborn with GBS-positive mother who deliver fewer than 4 hours after laboring and the influence of improving cervical diagnostics quality for postpartum Pap testing. Investigators hope the findings may have some effects on GBS sepsis and protocols as well as cervical diagnosis.
