Semestral Trends in Resistance of Staphylococcus spp. to Anti-MRSA Antibiotics in the ICU of a Tertiary Hospital in Alexandria, Egypt from 2020 to 2023. This figure shows the semestral resistance rates of Staphylococcus spp. to Methicillin, Vancomycin, Linezolid, and Teicoplanin in the intensive care unit (ICU) of a tertiary hospital in Alexandria, Egypt, from January 2020 to December 2023. Methicillin resistance remained consistently high, similar to hospital-wide trends. Resistance to Vancomycin, Linezolid, and Teicoplanin showed more fluctuation, with Vancomycin resistance peaking in 2020 followed by a gradual decline.
