Endocarditis caused by Streptococcus pneumoniae in children is an infrequent disease, corresponding to 3-7% of all cases of endocarditis. However, it is highly relevant because of its severity with the possibility of producing valvular ring abscesses and destruction, and high mortality that reaches up to 61% if medical and surgical treatment are not started early in the course of the illness. Over 50% of cases are associated to other sites of infection such as meningitis, pneumonia, sinusitis or mastoiditis. We report a 10-months-old infant who was admitted with meningitis and endocarditis due to S. pneumoniae, who presented with severe heart failure and required aortic valve replacement. A review of the literature of endocarditis caused by S. pneumoniae in pediatrics is presented.

Introduction: The ability to detect pathogenic bacteria before the onsets of severe respiratory symptoms and to differentiate bacterial infection allows to improve patient-tailored treatment leading to a significant reduction in illness severity, comorbidity as well as antibiotic resistance. As such, this study refines the application of the non-invasive Secondary Electrospray Ionization-High Resolution Mass Spectrometry (SESI-HRMS) methodology for real-time and early detection of human respiratory bacterial pathogens in the respiratory tract of a mouse infection model.
Methods: A real-time analysis of changes in volatile metabolites excreted by mice undergoing a lung infection by Staphylococcus aureus or Streptococcus pneumoniae were evaluated using a SESI-HRMS instrument.

Objectives: Periodontitis is an inflammatory and destructive disease caused by dental plaque, which can result in the immune microenvironment disorders and loss of periodontal support tissue. In order to promote the restoration of local microenvironment stability, a functional biomaterial Gelatin methacryloyl @MP196/exos based on characteristics of disease occurrence is designed.
Methods: Transmission electron microscopy, nanosight particle tracking analysis and western blot analysis were applied to prove the presence of exos in GelMA@MP196/exos.

Objectives: To investigate the protective effect of the probiotic bacterium K12 (K12) against (Mp) infection in mice.
Methods: Forty male BALB/c mice were randomized into normal control group, K12 treatment group, Mp infection group, and K12 pretreatment prior to Mp infection group. The probiotic K12 was administered daily by gavage for 14 days before Mp infection induced by intranasal instillation of Mp.
Background And Aim: Large number of studies proved undisputable role of procalcitonin (PCT) in sepsis diagnosis. Moreover, potential of procalcitonin to predict blood culture results according to Gram staining, different types of pathogens and foci of infection is discussed lately. The primary aim of our study was to compare the PCT levels in septic patients with documented Gram-positive and Gram-negative bacteraemia.

The emergence of antibiotic-resistant pathogens necessitates alternative therapies for treating microbial infections, especially in the oral cavity and upper respiratory tract. Our team has developed Phage Pastilles, a controlled-release formulation containing bacteriophages that target common pathogens, including Streptococcus pyogenes, Streptococcus salivarius, Staphylococcus aureus, Enterococcus faecalis, and E. coli.
