Moist soils at temperatures between -18 to 37ºC can support the growth of the fungus.

Organisms are known to survive in excess of 10 years in soil.

The most common way that healthcare providers test for histoplasmosis is by taking a blood sample or a urine sample and sending it to a laboratory. Healthcare providers may do imaging tests such as chest x-rays or CT scans of your lungs.

How easy is it to get histoplasmosis?

The infection is most commonly spread when these spores are inhaled after taking to the air, such as during demolition or cleanup projects. Soil contaminated by bird or bat droppings also can spread histoplasmosis, putting farmers and landscapers at a higher risk of the disease.

What does histoplasmosis look like on xray?

After heavy exposure, radiographs may show widely disseminated, diffuse, fairly discrete nodular shadows throughout the lungs, with individual lesions measuring 1-10 mm in diameter. This form of disease is termed miliary histoplasmosis (see the image below); it is similar to miliary tuberculosis.

How common is histoplasmosis?

How common is histoplasmosis? In the United States, an estimated 60% to 90% of people who live in areas surrounding the Ohio and Mississippi River valleys (where Histoplasma is common in the environment) have been exposed to the fungus at some point during their lifetime.

How is histoplasmosis treated?

Severe infections or disseminated cases of histoplasmosis require treatment with antifungal medications. Itraconazole (Sporanox, Onmel), fluconazole (Diflucan), and amphotericin B (Ambisome, Amphotec; drug of choice for severe disease) are antifungal drugs that treat histoplasmosis.

Does histoplasmosis ever go away?

What is the gold standard for treatment of histoplasmosis?

Culture is the gold standard for diagnosing histoplasmosis but is limited by a two- to four-week incubation period and decreased sensitivity to self-limited disease. 10–12 This method of diagnosis is not practical in cases of severe disease where delayed treatment may prove to be fatal.

Does histoplasmosis affect the liver?

Histoplasmosis is acquired by inhaling spores of the fungus. Most people do not have symptoms, but some feel sick and have a fever and cough, sometimes with difficulty breathing. Sometimes the infection spreads, causing the liver, spleen, and lymph nodes to enlarge and damaging other organs.

Does chest xray show histoplasmosis?

If a person has emphysema, gets symptoms that are like TB, and breathed in the fungus spores, health care providers may suspect chronic histoplasmosis. A chest X-ray may show lungs filled with fluid. In addition, blood tests for H. capsulatum are usually positive, and mucus specimens typically grow H.

Can histoplasmosis cause pneumonia?

How Histoplasmosis Affects Your Body. You get histoplasmosis by inhaling microscopic fungal spores that are released into the air by activities that disturb contaminated soil. Once inhaled, if the person has a healthy immune system, the fungus can cause mild symptoms and lead to lung infection or pneumonia.
