The prevalence of Methicillin-resistant Staphylococcus aureus (MRSA) has steadily increased over the past 40 years. Today, intravenous clindamycin or vancomycin is recommended for anti-staphylococcal coverage. Failure to identify resistant strains could result in the overuse of vancomycin and subsequent resistance to that antibiotic. Concerns over the emergence of this pathogen has caused many hospital laboratories to reassess their ability to identify antibiogram patterns and epidemiological shifts, determine appropriate laboratory testing, and review empiric therapy guidelines. Reliance on automated instrumentation to detect these isolates can result in major errors that cause false susceptible interpretations. The emergence of methicillin/oxacillin resistant strains has required additional laboratory analysis. This paper will review these tests and will focus on the role of the "D-test" in directing antibiotic therapy.

Background: Tick-borne encephalitis (TBE) is the most common tick-borne viral infection in Eurasia. Outcomes range from asymptomatic infection to fatal encephalitis, with host genetics likely playing a role. BALB/c mice have intermediate susceptibility to TBE virus (TBEV) and STS mice are highly resistant, whereas the recombinant congenic strain CcS-11, which carries 12.

Staphylococcaceae are a diverse bacterial family with important implications for human and animal health. This study highlights the One Health relevance of their environmental dispersal, particularly, by identifying closely related or genetically identical strains circulating between farm and community environments. Environmental Staphylococcaceae strains were isolated from animal farms and interconnected areas within a university setting, both influenced by anthropogenic activities.

Introduction: Molecular surveillance is an important tool for detecting chains of transmission and controlling the HIV epidemic. This can also improve our knowledge of molecular and epidemiological factors for the optimization of prevention. Our objective was to illustrate this by studying the molecular and epidemiological evolution of the cluster including the new circulating recombinant form (CRF) 94_cpx of HIV-1, detected in 2017 and targeted by preventive actions in 2018.

Bacterial heteroresistance, a phenomenon where subpopulations within a bacterial strain exhibit significantly reduced antibiotic susceptibility compared to the main population, poses a major challenge in managing infectious diseases. It is considered an intermediate stage in the evolution of bacteria towards full resistance. Heteroresistant strains often have a minimal inhibitory concentration (MIC) that appears sensitive, making detection and differentiation in clinical settings difficult.
