Hypervirulent Klebsiella pneumoniae (hvKp) is an emerging pathotype in addition to classical Klebsiella pneumoniae, with its ability to cause life-threatening, community-acquired metastatic infections even in healthy individuals. We presented a case of cerebral abscess preceded by otitis media in a 10-year-old child caused by hvKp. The isolates from blood pus aspirate were later identified as K. pneumoniae capsular serotype K2 and closely related to sequence type (ST65), with multiple hypervirulent genes detected (rmpA, rmpA2, iucA and peg344). She succumbed to death despite surgical drainage and susceptible antibiotic therapy. Clinicians should be cognizant of the rising incidence of hvKp infections in pediatric populations.

Background: The emergence of colistin resistance in carbapenem-resistant Klebsiella pneumoniae (CRKP) is a significant public health concern, as colistin has been the last resort for treating such infections. This study aimed to investigate the prevalence and molecular characteristics of colistin-resistant CRKP isolates in Central South China.
Methods: CRKP isolates from twelve hospitals in Central South China were screened for colistin resistance using broth microdilution.

Carbapenem-resistant Klebsiella pneumoniae poses a severe risk to global public health, necessitating the immediate development of novel therapeutic strategies. The current study aimed to investigate the effectiveness of the green algae Arthrospira maxima (commercially known as Spirulina) both in vitro and in vivo against carbapenem-resistant K. pneumoniae.

Purpose: To understand the mechanisms of carbapenem-resistant Klebsiella pneumoniae (CRKP) from Tanzania and characterize the genomes carrying the carbapenemase genes.
Methods: Clinical CRKP isolates were selected from ongoing antimicrobial-resistant surveillance at Muhimbili National Hospital, Dar es Salaam, Tanzania. Whole-genome sequencing was performed utilizing Illumina and Nanopore platforms.

Probiotics effectively alleviate host diarrhoea, but the specific mechanism is not clear. Therefore, we explored the protective mechanism of Bacillus coagulans (BC) on intestinal barrier injury induced by Klebsiella pneumoniae (K. pneumoniae) in rabbits by HE, immunofluorescence and 16S rRNA.

Objective: To investigate the interaction of inflammatory factors related to pulmonary infection and the TLR4/NF-κB signaling pathway in patients with spontaneous intracerebral hemorrhage (ICH).
Methods: A total of 325 critically ill ICH patients treated in our hospital from May 2021 to February 2024 were selected for this study. Based on whether the patient developed a pulmonary infection during treatment, they were divided into the infection group (n = 86) and the non-infection group (n = 239).
