A male adult patient on maintenance haemodialysis due to end-stage diabetic nephropathy presented with low-grade intermittent fever, cough and generalised weakness for 3 weeks. Initial blood investigations revealed an elevated neutrophil count with raised inflammatory markers. Chest CT revealed loculated hydropneumothorax with multiple cavitary nodules. Repeated blood cultures from the cuffed tunnelled catheter site and the right arm and sputum cultures were negative for pyogenic bacteria and yeast aetiology. The patient complained about left axillary pain on the fourth day of admission. Ultrasound-guided percutaneous aspiration from an axillary focal collection and subsequent culture revealed a methicillin-resistant (MRSA) infection. Echocardiography detected multiple vegetations on the tricuspid valve. The patient responded clinically to vancomycin and removal of the permanent catheter. This was a case of a tunnelled catheter-related metastatic MRSA infection with infective endocarditis, pulmonary septic embolism with a subacute presentation, and repeated blood culture negativity.

National epidemiological investigations of microbial infections greatly benefit from the increased information gained by whole-genome sequencing (WGS) in combination with standardized approaches for data sharing and analysis. To evaluate the quality and accuracy of WGS data generated by different laboratories but analysed by joint pipelines to reach a national surveillance approach. A national methicillin-resistant (MRSA) collection of 20 strains was distributed to nine participating laboratories that performed in-house procedures for WGS.

Introduction: Pertussis poses a significant threat to infants under six months due to their immature immune systems, limited maternal antibody protection, and constraints in the vaccination schedule. Despite vaccination efforts, this group remains highly susceptible to severe complications. Addressing these challenges is crucial for improving the health outcomes of infants in China.

Purpose Of Review: This narrative review discusses the mechanisms connecting gut dysbiosis to adverse clinical outcomes in critically ill patients and explores potential therapeutic strategies.
Recent Findings: In recent years, the study of microbiota in ICUs has gained attention because of its potential effects on patient outcomes. Critically ill patients often face severe conditions, which can compromise their immune systems and lead to opportunistic infections from bacteria typically harmless to healthy individuals.
