The purpose of this study is to draw blood from healthy donors for use in neutrophil studies to assess effects against bacteria.

The purpose of this study is to test whether metagenomic shotgun sequencing can identify pathogens causing cardiovascular infections such as infective endocarditis or myocarditis.

The purpose of this study is to see if molecular methods can predict Helicobacter pylori antimicrobial resistance patterns and predictions agree with current gold standard antibacterial susceptibility testing (AST) agar dilution.  

The purpose of this study is to characterize and compare the local and systemic immune landscape in patients with PJI versus those with non-infected arthroplasty failure (NIAF) by performing high-dimensional immune profiling on synovial fluid, residual peri-implant tissue, and peripheral blood.

The purpose of this study is to determine the sensitivity, specificity, positive and negative predictive values of molecular detection of microorganisms, detection of microbial proteins and antibodies against microorganisms, and inflammatory markers (e.g., leukocyte esterase, CRP) in synovial fluid for the diagnosis of prosthetic joint infection (PJI).

The objective of this study is to evaluate the impact of the Alere™ PBP2a test combined with pharmacist review of antimicrobial therapy, on clinical outcomes and cost in hospitalized patients with sterile site S. aureus infection.

The purpose of this study is to demonstrate the tests' performance when compared to the detection of periprosthetic joint infection (PJI) using the Musculoskeletal Infection Society (MSIS) criteria-based definition of PJI for diagnosing PJI. This criteria-based definition of PJI places emphasis on culture techniques that identify pathogens, but also provides for minor criteria that can be used to diagnose PJI. This study will also calculate the tests' clinical sensitivity, clinical specificity, positive predictive value (PPV), and negative predictive value (NPV).

This study includes collection of blood samples from the healthy controls and those with suspected bloodstream infections.

The Curetis Unyvero LRT55 Application is intended to detect and to identify genes of 21 microorganisms and 19 genes associated with antibiotic resistance in 4 hours.

In this study, the performance of the Unyvero LRT55 Application shall be tested under clinical conditions and compared to (1) a composite reference method (for non-atypical or cultured microorganisms) or (2) a molecular PCR based reference method for the 3 atypical microorganisms Chlamydophila pneumoniae, Legionella pneumoniae, and Pneumocystis jirovecii, and for resistance genes.

PCR amplifications are followed by bi-directional sequencing, including comparison of the test results Time to result will be compared for the Unyvero LRT55 Application and standard-of care.

The purpose of this study is to determine the number of de-identified discard throat swabs submitted for testing for group A streptococcus that are positive for Fusobacterium necrophorum.  Determine the number of anonymously self-collected throat swabs from normal volunteers that are positive for F. necrophorum.

The aim of this study is to identify difficult to diagnose microbial pathogens causing infections using blood or urine for identification of bacteria, viruses, fungi or parasites that are not detectable or are difficult to detect using current diagnostic techniques.

The purpose of this study is to determine whether metagenomic shotgun sequencing can identify microorganisms present in blood sample of patients with febrile neutropenia. 

This study will provide archived, clinical residual stool specimens to Meridian Bioscience, Inc. These specimens will be used by Meridian to perform research studies, such as feasibility, method characterization, verification, and validation studies with in vitro diagnostic devices under development.

The purpose of this study is to confirm lack of toxicity of small (2 cm2) H202-generating e-bandages on normal human skin over a 24 hour period.  

This study will compare plasma ammonia levels among neonates with and without Ureaplasma colonization of their respiratory tract. It will compare neonates with and without Ureaplasma colonization to identify differences in clinical characteristics, including gestational age, mode of delivery, comorbidities, and clinical status. It will also compare neonates with and without hyperammonemia to identify differences in clinical characteristics, including gestational age, mode of delivery, comorbidities, and clinical status.

The purpose of this study is to determine diagnostic usefulness by comparing the rate of positive synovial fluid T. whipplei PCR tests, with the clinical characteristics and outcomes of patients who have Whipple's disease.
