Breakpoints for the same organism and antibiotic may differ based on the site of infection: [29] for example, the CLSI generally defines Streptococcus pneumoniae as sensitive to intravenous penicillin if MICs are ≤0.06 μg/ml, intermediate if MICs are 0.12 to 1 μg/ml, and resistant if MICs are ≥2 μg/ml, but for cases of meningitis, the ...
Amphotericin B is an antifungal medication used for serious fungal infections and leishmaniasis. [3] The fungal infections it is used to treat include mucormycosis, aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, and cryptococcosis.

Antifungal resistance is a One Health concern, driven by multiple extrinsic factors, including extensive fungicidal use, overuse of clinical antifungals, environmental change and host factors. [ 1 ] Like resistance to antibacterials, antifungal resistance can be driven by antifungal use in agriculture.
Antifungal medications that target ergosterol synthesis are selectively toxic to the fungi, hence, killing and stopping the growth of fungi in the body. When ergosterol is damaged, it causes the contents inside the fungal cells to leak out, preventing further reproduction of fungal cells. Lastly, antifungal agents contribute to fungal cell death.
Fluconazole is an antifungal medication used for a number of fungal infections. [5] This includes candidiasis, blastomycosis, coccidioidomycosis, cryptococcosis, histoplasmosis, dermatophytosis, and tinea versicolor. [5]
While the MIC is the lowest concentration of an antibacterial or antifungal agent necessary to inhibit visible growth, the minimum bactericidal concentration (MBC) is the minimum concentration of an antibacterial agent that results in bacterial death. It is defined by the inability to re-culture bacteria, and the closer the MIC is to the MBC ...
