Abstract:
Resistance to antibiotics and the directly related proportion of multiresistant bacterial pathogens (MRP) is increasing continuously. This applies particularly for intensive care units. The most relevant MRP are methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), extended spectrum ss-lactamase formers (ESBL), multiresistant pseudomonades and Acinetobacter species. According to WHO the world is in danger of entering a so-called "post-antibiotic era", in which it is no longer possible to treat the causes of infectious diseases with antibiotics. The reasons for this development are considered to be the increased morbidity of patients as well as the too frequent, too long-enduring and often inappropriate usage of antimicrobial substances. But also the increasing number of invasive measures and interventions as well as the still existing inadequate maintenance of hygiene standards and the inadequate establishment of non-medicamentous measures (e.g. hand disinfection) for infection prophylaxis play a significant role.
Insights
Antibiotic resistance and multidrug-resistant pathogens are rising, especially in intensive care units, threatening a post-antibiotic era. Inappropriate antimicrobial use and poor hygiene practices are key drivers of this critical global health challenge.
Area of Science:
- Microbiology and Infectious Diseases
- Public Health
- Clinical Medicine
Context:
- Increasing prevalence of multidrug-resistant pathogens (MRP), including MRSA, VRE, ESBL, Pseudomonas, and Acinetobacter species, particularly in intensive care units.
- Global health threat recognized by WHO, potentially leading to a 'post-antibiotic era' where common infections become untreatable.
- Rising patient morbidity and increased use of invasive procedures contribute to the spread of resistant bacteria.
Purpose:
- To highlight the escalating crisis of antibiotic resistance and multidrug-resistant pathogens.
- To identify key factors contributing to the rise of antimicrobial resistance.
- To underscore the urgent need for improved infection control and antimicrobial stewardship.
Summary:
- Antibiotic resistance is a continuous and growing problem, with multidrug-resistant pathogens (MRP) posing a significant threat, especially in intensive care settings.
- Key MRPs include MRSA, VRE, ESBL-producing bacteria, and resistant strains of Pseudomonas and Acinetobacter.
- Factors driving this include increased patient morbidity, overuse and misuse of antimicrobials, invasive medical interventions, and inadequate hygiene standards, including insufficient hand disinfection.
Impact:
- Potential shift to a 'post-antibiotic era' with severe implications for treating infectious diseases.
- Increased morbidity and mortality due to untreatable infections.
- Urgent need for global strategies focusing on antimicrobial stewardship, infection prevention, and hygiene protocols.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
