Candidemia, predominantly caused by C. albicans, poses a significant threat in hospitals. Yet, non-albicans candidemia (NAC) and antifungal resistance are increasing concerns.

Methods: Sixty unique S. pneumoniae challenge strains were selected to cover a wide range of penicillin, ampicillin and cefotaxime minimal inhibitory concentrations (MICs).
Background: Aztreonam-avibactam (ATM-AVI) combination shows promising effectiveness on most carbapenemase-producing Gram-negatives, yet standardized antibiotic susceptibility testing (AST) methods for evaluating the combination in clinical laboratories is lacking. We aimed to evaluate different ATM-AVI AST approaches.
Methods: 96 characterized carbapenem-resistant clinical isolates belonging to 9 Enterobacterales (EB; n = 80) and P.
Article Synopsis
- Triazole-resistant Aspergillus fumigatus (TRAF) is increasingly recognized as a public health issue globally, but data on its prevalence in Africa, particularly West Africa, is scarce.
- The study involved collecting air samples from multiple hospital wards in Burkina Faso that house patients susceptible to invasive aspergillosis, revealing a TRAF prevalence of 3.23%.
- Notably, one isolate exhibited pan-triazole resistance linked to the TR34/L98H mutation, marking the first detection of such resistance in the country and highlighting the importance of continuous surveillance for TRAF.
Purpose: Antifungal susceptibility testing (AFST) is essential to ensure appropriate antifungal therapy in candidaemia. This study compared two commercial colorimetric broth microdilution tests: Sensititre YeastOne (SYO; Thermo Scientific) and Micronaut-AM EUCAST AFST (M-AM; Bruker) for the AFST of Candida spp.
Material And Methods: A total of 74 yeast strains, including C.
