Objective: This study aimed to determine the bacteriological profile of childhood acute bacterial meningitis in Pakistan.
Patients And Methods: The study included a total of 100 children aged between 1 month and 5 years, who were admitted with a diagnosis of meningitis based on clinical findings and positive cerebrospinal fluid (CSF) tests. Out of the 100 CSF samples collected, 21 isolates were confirmed to contain Enterobacteriaceae. The most prevalent Enterobacteriaceae species were Pseudomonas (n=8, 38.09%), Klebsiella (n=4, 19.04%), E. coli (n=4, 19.04%), and Acinetobacter (n=4, 19.04%), while Citrobacter (n=1, 4.76%) was less common. Antibiotic susceptibility patterns were analyzed for these isolates.
Results: Pseudomonas (n=8) exhibited 25% resistance to cefepime and 38% resistance to imipenem. Klebsiella (n=4) showed 75% resistance to imipenem. Acinetobacter (n=4) demonstrated 50% resistance to imipenem, along with varying resistance to cefepime, amikacin, ciprofloxacin, and gentamicin. E. coli (n=4) showed 0% resistance to imipenem and amikacin. However, Citrobacter (n=1) showed 0% resistance to ciprofloxacin, aztreonam, gentamicin, amikacin, levofloxacin, and cefepime. Acute bacterial meningitis primarily affects children under 1 year of age.
Conclusions: CSF culture revealed that Gram-negative bacteria, specifically Pseudomonas spp., were the predominant pathogens in this family based on Pakistani data.

In this study, the mechanisms implicated in delafloxacin resistance in strains were investigated. Delafloxacin is a novel, broad-spectrum fluoroquinolone that has been approved for clinical application. In our study, 43 strains were assessed, antimicrobial susceptibility testing was performed via the broth microdilution method, and the minimum inhibitory concentration (MIC) values for ciprofloxacin, delafloxacin, levofloxacin, moxifloxacin, ceftazidime, cefotaxime, and imipenem were determined.

Background: Initial antimicrobial therapy for pneumonia is frequently empirical and resistance to antimicrobial agents represents a great challenge to the treatment of patients hospitalized with pneumonia. We evaluated the frequency and antimicrobial susceptibility of Gram-negative bacteria causing pneumonia in US hospitals.
Methods: Bacterial isolates were consecutively collected (1/patient) from patients hospitalized with pneumonia and the susceptibility of Gram-negative bacilli (3,911 Enterobacterales and 2,753 non-fermenters) was evaluated by broth microdilution in a monitoring laboratory.

(PA), as a common pathogen of nosocomial infections, has been experiencing an increasing rate of drug resistance with the widespread use and abuse of antimicrobial drugs. High-drug-resistance and high-virulence phenotypes are two distinctive features of the strong pathogenicity of multi-drug-resistant PA. Exploring the characterization of virulence factor expression and its relationship with the multi-drug resistance phenotype is essential to reduce the further development of resistance as well as a high standard of infection prevention and control.

Introduction: This study analyzes urinary tract infections (UTIs) in a hospital in Central Portugal over a five-year period, focusing on bacterial prevalence, patient demographics, and antibiotic resistance patterns. This investigation aims to provide insights that can guide improved infection control and treatment strategies.
Methods: A total of 6161 positive urine cultures collected over five years were examined, with particular emphasis on 2019 due to a peak in infection rates.

Background: The Infectious Diseases Society of America (IDSA) publishes annual guidance on the treatment of antimicrobial-resistant (AMR) gram-negative infections. Within the AMR guidance, suggested dosages of antibiotics for adults infected with AMR pathogens are provided. This document serves as a companion document to the IDSA guidance to assist pediatric specialists with dosing β-lactam agents for the treatment of AMR infections in children.
