This is the first report of secondary resistance to rifampin following MDT in a patient with prolonged, but irregular treatment. Repeated mouse foot-pad studies demonstrated resistance to dapsone after several years of monotherapy, and following subsequent MDT the studies demonstrated the development of resistance to rifampin.

Background: World Health Organization in the year 2020 recommended the use of Truenat as a replacement for smear microscopy in Tuberculosis (TB) diagnosis and detection of rifampicin resistance. This study was designed to assess enablers and barriers to effective implementation of Truenat assays for TB diagnosis in Nigeria and determine the acceptability of use of Truenat among healthcare workers and TB Program managers in Nigeria.
Methods: A descriptive exploratory study design was used.

\nKlebsiella pneumoniae is a common pathogen of healthcare-associated infections expressing a plethora of antimicrobial resistance loci, including ADP-ribosyltransferase coding genes (arr), able to mediate rifampicin resistance. The latter has activity against a broad range of microorganisms by inhibiting DNA-dependent RNA polymerases. This study aims to characterise the arr distribution and genetic context in 138 clinical isolates of K.

The widespread resistance of enterococci to many commonly used antimicrobial agents is a growing concern. Given that the current treatment options for enterococcal infections are limited, the discovery of new therapies, including combination therapies, is necessary. We evaluated double-drug combinations of lefamulin with doxycycline, rifampin, and quinupristin/dalfopristin for in vitro synergy against strains of () and () by using checkerboard and time-kill assays.

: species have become significant sources of infections acquired in hospital settings and are commonly linked to high mortality rates. Antimicrobial resistance can be influenced by species, geographical location, antimicrobial susceptibility testing methods, and the time of bacterial isolation. There are distinct antimicrobial susceptibility patterns among species, and the investigation into potential antibiotic susceptibility variations among species is beneficial.

Rifampin is a crucial antibiotic in the management of prosthetic joint infections (PJI), particularly due to its effectiveness against staphylococcal bacteria and its ability to penetrate and disrupt biofilms. This review evaluates rifampin's role by examining its mechanism of action, clinical efficacy, and integration into treatment regimens based on recent evidence and guidelines. Rifampin's synergistic effects with other antibiotics, such as β-lactams and vancomycin, enhance bacterial eradication, and some evidence shows that it improves patient outcomes.
