crossresistentie

Crossresistance, also known as cross-resistance or cross-resistance, is a phenomenon in pharmacology and microbiology where an organism's resistance to one antibiotic is associated with its resistance to another antibiotic. This occurs because the mechanisms of resistance to different antibiotics may overlap or be linked. For example, an organism that is resistant to one class of antibiotics may also be resistant to another class due to the same or similar resistance mechanisms.

Crossresistance can be either intrinsic or acquired. Intrinsic crossresistance occurs naturally within an organism, while acquired crossresistance develops as a result of exposure to antibiotics. This phenomenon is particularly relevant in the context of antibiotic stewardship and the development of antibiotic resistance.

Understanding crossresistance is crucial for developing effective antibiotic treatment strategies. It helps in predicting which antibiotics may be effective against a particular organism and in designing combination therapies to overcome resistance. However, it also highlights the importance of prudent antibiotic use to prevent the spread of resistant strains.

In summary, crossresistance is a significant factor in antibiotic resistance, influencing both the treatment of infectious diseases and the development of new antibiotics. It underscores the need for careful management of antibiotic use to combat the growing threat of antibiotic resistance.
