Stool Tests Rapidly Predict H. pylori Antibiotic Resistance

Helicobacter pylori eradication rates have declined in concert with rising antimicrobial resistance worldwide. There is a need for rapid accurate, reliable antibiotic resistance testing, especially in refractory cases. More...

Neglected Protists Found in Immunocompetent and Immunodeficient Diarrheal Patients

Diarrhea is one of the most widespread gastrointestinal symptoms and is a common problem in immunosuppressed patients. The spectrum of pathogens that cause diarrhea in immunosuppressed patients is significantly different from those in patients with a normal immune system. More...

Immune Chemokines Biomarkers Explored for Pediatric Tuberculosis Diagnosis

Diagnosis of active tuberculosis (TB) in children provides a key challenge, because most of the clinical symptoms of TB in children are non-specific with signs and symptoms that resemble common pediatric illnesses, including pneumonia and malnutrition and therefore clinical diagnosis is unreliable. More...

YKL-40 Associated with Severity in Patients with Necrotizing Soft-Tissue Infection

Necrotizing soft-tissue infection (NSTI) is a rare, severe and fast-progressing bacterial infection. NSTI can be caused by a myriad of aerobic, anaerobic and facultative anaerobic bacteria, but predominantly by Group A Streptococcus in monomicrobial infections. More...

Osteopontin Biomarker Evaluated for COVID-19 Severity and MIS-C

Multisystem inflammatory syndrome in children (MIS-C) is a serious condition that appears to be linked to coronavirus disease 2019 (COVID-19). Most children who become infected with the COVID-19 virus have only a mild illness. More...

Quantity of Toxin in Stool Correlates with C. difficile Severity

Clostridioides difficile (syn. Clostridium difficile), also known as C. difficile, or C. diff are Gram-positive species of spore-forming bacteria. Clostridioides spp. are anaerobic, motile bacteria, ubiquitous in nature and especially prevalent in soil. C. difficile cells are Gram-positive and show optimum growth on blood agar at human body temperatures in the absence of oxygen. More...
