Adherence of Clostridium difficile to Vero cells under anaerobic conditions was increased by a high sodium concentration, calcium-rich medium, an acidic pH, and iron starvation. The level of adhesion of nontoxigenic strains was comparable to that of toxigenic strains. Depending on the bacterial culture conditions, Vero cells could bind to one, two, or three bacterial surface proteins with molecular masses of 70, 50, and 40 kDa.

Importance: Uncomplicated urinary tract infection (UTI) is a common indication for outpatient antimicrobial therapy. National guidelines for the management of uncomplicated UTI were published in 2011, but the extent to which they align with current practices, patient diversity, and pathogen biology, all of which have evolved greatly in the time since their publication, is not fully known.
Objective: To reevaluate the effectiveness and adverse event profile for first-line antibiotics, fluoroquinolones, and oral β-lactams for treating uncomplicated UTI in contemporary clinical practice.

Introduction: Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease presenting with remission and flares. Relapses may be triggered by various factors, with infections being one of the most common. The following case is the first clostridium difficile infection (CDI)-induced SLE flare that resulted in involvement of organs not previously affected in patient's history before, such as lupus nephritis.

Introduction: Antibiotic stewardship is a critical aspect of managing cancer patients with febrile neutropenia (FN) to limit the development of drug-resistant organisms and minimize adverse drug effects. Thus, it has been recommended that patients with FN receiving empiric antibiotics should be re-evaluated for safe antibiotic de-escalation.
Methods: Subjects treated with meropenem for febrile neutropenia who met Loyola University Medical Center's (LUMC) criteria for de-escalation were stratified based on whether meropenem was de-escalated, and 30-day all-cause mortality for both groups was assessed.
Comparison of Illumina and Oxford Nanopore sequencing data quality for Clostridioides difficile genome analysis and their application for epidemiological surveillance.

Background: The burden of Clostridioides difficile as a nosocomial- and community-acquired pathogen has been increasing over the recent decades, including reports of severe outbreaks. Molecular and virulence genotyping are central for the epidemiological surveillance of this pathogen, but need to balance accuracy and rapid turnaround time of the results. While Illumina short-read sequencing has been adopted as the gold standard to investigate C.
