technical field [0001] The invention relates to the field of microbial antibacterial technology, in particular to the application of papaya saponins in the preparation of anti-candida albicans fluconazole-resistant strain products and anti-dermatophyte products. Background technique [0002] Candida is the most common class of opportunistic pathogens, and Candida albicans is one of the main pathogens. As a routine drug for the treatment of Candida, fluconazole is still the first-line drug for clinicians to treat Candida infection. However, with the routine use of the drug, fluconazole-resistant Candida albicans is also increasing. Epidermophyton flocculus can infect humans. The host can be humans, wild animals or pets, but it prefers humans. It can infect the skin and nails, thereby causing tinea pedis, tinea corporis, jock itch or onychomycosis. It can be passed through Contact infection. Microsporum gypsumoid is one of the pathogens of zoonotic superficial mycoses, whic...
