Blastomyces dermatitidis, the etiologic agent of blastomycosis, is a thermally dimorphic fungus that grows as a filamentous mold in the environment and as budding yeast in human tissue. This pathogen is endemic to North America, particularly in the states bordering the Mississippi and Ohio rivers, the Great Lakes, and the St. Lawrence Seaway. Infection with B. dermatitidis causes a broad array of clinical manifestations ranging from asymptomatic infection to fulminant sepsis with acute respiratory distress syndrome and death. B. dermatitidis can infect almost any organ in the body, but has a predilection for lungs and skin. There have been recent advances in the understanding of the pathogenesis, diagnosis, and treatment of this fungus. The Infectious Diseases Society of America published updated guidelines in 2008 to guide clinicians in the treatment of this important pathogen.

infections are classified as dimorphic fungal infections commonly seen geographically throughout the Mississippi and Ohio River Valleys, St. Laurence Seaways, as well as the Canadian providences of Ontario Manitoba, and Saskatchewan. Although primarily endemic in the Midwestern United States, there has been a rise in cases throughout New England.

Background: Itraconazole (ICZ) has been approved by the FDA to treat many fungal infections including, blastomycosis, histoplasmosis, and aspergillosis. ICZ can be also used as prophylaxis in the population who are at high risk for developing systemic fungal infections, such as HIV patients, and chemotherapy patients.
Aim: However, since ICZ is a BCS Class II drug that has low solubility and high permeability, leads to low oral bioavailability.

Exploring the variability of the intestinal flora of patients with hepatic blastocysticercosis and searching for members of the intestinal microflora that may play a role in the disease process by means of macro-genome sequencing technology. A case-control study was used to include fecal samples from patients with hepatic vesicular schistosomiasis admitted to Qinghai Provincial People's Hospital between October 2023 and January 2024 and individuals attending health checkups. The experimental group (AE group) consisted of 10 patients with liver vesicular schistosomiasis and the control group (NC group) consisted of 9 individuals attending health checkups.

Introduction: With reports of expanding epidemiology of blastomycosis across the United States, the purpose of this study was to evaluate the incidence and outcomes associated with blastomycosis in solid organ transplant (SOT) and hematopoietic cell transplant (HCT) recipients.
Methods: We conducted a retrospective case series of adult SOT and HCT recipients at a tertiary care medical center between January 1, 2005 and September 30, 2023. Cases were defined as culture-proven blastomycosis.
