Abstract
In order to compare the effectiveness of liposomal amphotericin B (LAB) and caspofungin monotherapy in Candida tropicalis-induced peritonitis in an experimental mice model 56 healthy male BALB/c mice (10-12 weeks; 20-25 g) were divided into groups and C. tropicalis strains were intraperitoneally (IP) inoculated into mice groups except the control group. After the injection, three doses of LAB (0.5, 1.0, 2.0 mg/kg/day) and caspofungin (1.0, 2.0, 5.0 mg/kg/ day) were administered to groups for five consecutive days, starting 48 h post-infection. The mice were then followed up for 14 days and killed by cervical dislocation. When their peritoneal fluid was examined, the difference in fungal growth between the treatment group and control group was significant (p<0.05). Evaluation of the treatment groups revealed that fungal growth decreased with increasing dose of the antifungal agent (p>0.05). There was no dose-related difference from mice which received LAB or those which received caspofungin in our experimental model. During our study, no death was detected despite the similar injection doses compared with other studies using Candida species. The results of this study suggest that C. tropicalis could have lower virulence, perhaps limited by natural immunity, and causes mortality at much higher doses. © 2019, EDIMES Edizioni Medico Scientifiche.
