Aim: Antibiotic resistance mediated by extended-spectrum β-lactamases (ESBL) and AmpC β-lactamases is widespread and increasingly common, often rendering empiric antibiotic therapy ineffective. In septicemia, delays in initiating effective antibiotic therapy are associated with worse clinical outcomes. With current phenotypic antimicrobial susceptibility testing methods, there is often a delay of 18-24 h before the susceptibility of an isolate is known.
Results: Using an HPLC assay, breakdown of the third-generation cephalosporin cefotaxime by ESBL- and AmpC- β-lactamase-producing organisms could be detected within 90 min with 86.4% sensitivity and 100% specificity; sensitivity for ESBL detection was 100%.
Conclusion: This assay could be readily established in any clinical laboratory with an HPLC to rapidly detect ESBL-producing .

Background: tNGS and mNGS are valuable tools for diagnosing pathogens in lower respiratory tract infections (LRTIs), which subsequently influence treatment strategies. However, the impact of tNGS and mNGS on antimicrobial stewardship in patients with LRTIs remains unclear.
Methods: Patients diagnosed with LRTIs who underwent tNGS or mNGS between June 2021 and January 2024 were included.

Dental caries is a highly prevalent chronic condition globally. In recent years, scientists have turned to natural compounds such as plant extracts as an alternative to address concerns related to biofilm-mediated disease transmission, increasing bacterial resistance, and the adverse impacts of antibiotics. Consequently, this study investigated the antimicrobial properties of ethanolic, hydroethanolic, and aqueous extracts of L.

Traumatic optic neuropathy (TON) is a rare condition resulting from damage to the optic nerve due to craniofacial trauma. It can present as direct or indirect injuries, with mechanisms ranging from mechanical disruption by fractures in direct TON to transmitted forces causing shearing and ischemia in indirect TON. These injuries often lead to significant visual impairment or complete vision loss, requiring timely diagnosis and intervention.

Purpose Hepatic abscesses remain a significant clinical challenge due to high morbidity and mortality. This research aims to examine the etiological spectrum, management approaches, clinical features, and results in hepatic abscesses in a tertiary care facility in northern India, emphasizing the distinctions among pyogenic liver abscesses (PLAs) and amoebic liver abscesses (ALAs). Methods This retrospective study was done at GSVM Medical College, Kanpur, analyzing 725 patients with hepatic abscesses over a 10-year period.

Introduction The success of surgical procedures is becoming more threatened by the advent of multi-drug resistant (MDR) bacterial strains, sometimes known as superbugs. These resistant microorganisms frequently cause post-surgical infections, which raise morbidity, death, and medical expenses. With an emphasis on resistant strains, this seeks to create an antibiogram and a thorough microbiological profile of surgical infections in order to help choose the most effective antimicrobial therapy.
