We evaluated the in vitro activities of terbinafine alone and in combination with amphotericin B, fluvastatin, rifampicin, metronidazole or ibuprofen against 17 clinical isolates of Pythium insidiosum. The assays were based on technique M38-A2, as well as the checkerboard microdilution method. The main synergism observed was by combination of terbinafine plus amphotericin B (41.18%). Antagonisms were observed in combinations of terbinafine with fluvastatin (35.30%) or rifampicin (5.88%).

Naegleria fowleri is the causative agent of a type of encephalitis called Primary Amoebic Encephalitis (PAM). Almost 98 % of PAM cases reported worldwide are fatal and affect mostly immunocompetent children and young adults. The current therapeutic option against PAM cases includes a combination of miltefosine, amphotericin B and other drugs which are unfortunately associated with severe side effects.

causes a deadly disease called primary amoebic meningoencephalitis (PAM). Even though PAM is still considered a rare disease, the number of reported cases worldwide has been increasing each year. Among the factors to be considered for this, awareness about this disease, and also global warming, as these amoebae thrive in warm water bodies, seem to be the key factors.

Statin compounds, which are routinely used as cholesterol-lowering drugs, may also exert direct antimicrobial effects. In this study, the in vitro antifungal activities of various statins (lovastatin, simvastatin, fluvastatin, atorvastatin, rosuvastatin and pravastatin) were examined against one isolate each of four dermatophyte species (Trichophyton mentagrophytes, Trichophyton rubrum, Microsporum canis and Microsporum gypseum).

Fusarium spp is an opportunistic fungal pathogen responsible for causing invasive hyalohyphomycosis in immunocompromised patients. Due to its susceptibility pattern with a remarkable resistance to antifungal agents the treatment failures and mortality rates are high. To overcome this situation, combination therapy may be considered which must be subjected to in vitro tests.

The in vitro antifungal activity of different statins and the combinations of the two most effective ones (fluvastatin and rosuvastatin) with amphotericin B were investigated in this study on 6 fungal isolates representing 4 clinically important genera, namely Absidia, Rhizomucor, Rhizopus and Syncephalastrum . The antifungal effects of statins revealed substantial differences. The synthetic statins proved to be more effective than the fungal metabolites.
