AI Article Synopsis
- Non-typhi Salmonella species typically cause severe infections in immunocompromised patients, but a rare case is reported in an immunocompetent man.
- A 44-year-old Japanese man developed septic arthritis and a bone abscess from Salmonella enterica serovar Ohio after a long asymptomatic period with no recent travel or food poisoning history.
- This case highlights that non-typhi Salmonella can lead to serious infections in healthy individuals many years after initial bacteremia.
Article Abstract
Introduction: Non-typhi Salmonella species cause severe extra-intestinal focal infection after occult bacteremia. Although the number of cases of non-typhi salmonellosis is increasing worldwide among patients with immunocompromising conditions such as human immunodeficiency virus infection, infection is uncommon in immunocompetent subjects. We report a case of septic arthritis and bone abscess due to a rare non-typhi Salmonella organism that developed after a prolonged asymptomatic period.
Case Presentation: A 44-year-old Japanese immunocompetent man presented with acute-onset left knee pain and swelling. He had no history of food poisoning, and his most recent travel to an endemic area was 19 years ago. Salmonella enterica serovar Ohio was identified from samples of bone abscess and joint tissue. Arthrotomy and necrotic tissue debridement followed by intravenous ceftriaxone was successful.
Conclusions: Non-typhi Salmonella species only rarely cause extra-intestinal focal infections in immunocompetent patients. Our case suggests that non-typhi Salmonella species can cause severe focal infections many years after the occult bacteremia associated with food poisoning.

Introduction: Salmonella infections usually present as self-limiting gastrointestinal illnesses. Salmonella pneumonia is an uncommon infection that should be considered in immunodeficient individuals originally presenting with enterocolitis. With fewer than 40 reported cases, salmonella pneumonia can rarely lead to empyema (1.

Ensuring food safety, particularly for vulnerable groups, like infants and young children, requires identifying and prioritizing potential hazards in food chains. We previously developed a web-based decision support system (DSS) to identify specific microbiological hazards (MHs) in infant and toddler foods through a structured five-step process. This study takes the framework further by introducing systematic risk ranking (RR) steps to rank MH risks with seven criteria: process survival, recontamination, growth opportunity, meal preparation, hazard-food association evidence, food consumption habits of infants and toddlers in the EU, and MH severity.

Article Synopsis
- Severe bacterial infections in children require quick and effective antibiotic treatment, but challenges were identified in a study at a Kisantu hospital on non-typhi Salmonella bloodstream infections.
- While 98.4% of children received antibiotics, there were significant issues with timing, administration, and dosing accuracy, with only 78.3% receiving antibiotics on the day of admission.
- Problems included the use of inappropriate administration practices, poor-quality oral formulations, and a lack of essential dosing instructions, highlighting an urgent need for improvements in antibiotic management for pediatric care.

Article Synopsis
- Diagnosis of bacterial meningitis in developing countries is complicated by low culture yields and non-prescription antibiotic use, prompting a study that compares traditional bacterial culture methods with the BioFire® FilmArray® Meningitis/Encephalitis Panel.
- The study analyzed 400 cerebrospinal fluid samples from children under five, finding that while 8% were culture positive, the BioFire ME Panel identified pathogens in 24.5% of culture-negative samples.
- The BioFire® ME Panel proved to be more sensitive and quicker than standard culture methods, successfully detecting both bacterial and viral agents associated with meningitis.
