Introduction: Antibiotic susceptibility tests (AST) done on blood cultures are critical for the treatment of patients suspected to be suffering from bloodstream infection. The objective of this study was to evaluate the accuracy and reliability of disc diffusion AST conducted directly (direct AST) from flagged-positive blood cultures, especially for Gram-positive cocci bacteria.
Methodology: This study compared direct AST with conventional AST (broth micro-dilution).
Background And Aim: The emergence of methicillin-resistant (MRSA) as a highly pathogenic strain in veterinary and human medicine is a growing global problem. This study aimed to evaluate MRSA isolates of human and animal origin against various antibiotics in Yogyakarta, Indonesia.
Materials And Methods: The susceptibility test was carried out by the disk diffusion method using Mueller-Hinton agar against nine antibiotic disks.
Background: Transmission within families and multiple spike protein mutations have been associated with the rapid transmission of SARS-CoV-2. We aimed to: (1) describe full genome characterization of SARS-CoV-2 and correlate the sequences with epidemiological data within family clusters, and (2) conduct phylogenetic analysis of all samples from Yogyakarta and Central Java, Indonesia and other countries.
Methods: The study involved 17 patients with COVID-19, including two family clusters.
Objective: Several studies reported that infection of extended-spectrum β lactamase (ESBL)-producing Escherichia coli (E. coli) or Klebsiella pneumoniae (K. pneumoniae) contributed to higher mortality rates but others found it was not associated with mortality.
