Yeasts like Candida albicans and Cryptococcus neoformans are common fungal pathogens. C. albicans causes infections like candidiasis when the immune system is weakened or normal flora is disrupted by antibiotics. C. neoformans causes the sub-acute infection cryptococcosis, most commonly manifesting as meningitis. Both fungi are found worldwide and enter the body through inhalation, then diagnosis involves examining clinical specimens under a microscope or using serological tests. Treatment depends on the infecting species but generally involves antifungal drugs like amphotericin B and fluconazole.
