Initial symptoms of cryptococcosis include fever, fatigue, and a dry cough. In immunocompromised patients, infections often disseminate to the brain. The resulting meningitis produces headaches, sensitivity to light, and confusion. If left untreated, the disease can be fatal.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

Signs and Symptoms of Cryptococcosis

Treatment of cryptococcosis involves Amphotericin B, in combination with flucytosine. Amphotericin B is a broad-spectrum antifungal drug that targets fungal cell membranes. It can also adversely impact host cells and produce side effects. Clinicians must carefully balance the risks and benefits of treatments in these patients. It is difficult to eradicate cryptococcal infections, so patients usually need to take fluconazole for up to 6 months after treatment with amphotericin B and flucytosine to clear the fungus.

Treatment of Cryptococcosis

Cryptococcosis is often diagnosed based on microscopic examination of lung tissues or cerebrospinal fluids. India ink preparations can be used to visualize the extensive capsules that surround the yeast cells. Serological tests are also available to confirm the diagnosis.

Diagnosis of Cryptococcosis

*Cryptococcus neoformans* is ubiquitous in the soil and can be isolated from bird feces. Immunocompromised people are infected by inhaling basidiospores found in aerosols. The thick polysaccharide capsule surrounding these microbes enables them to avoid clearance by the alveolar macrophage. In immunocompromised patients, pulmonary infections often disseminate to the brain.
