Histoplasma capsulatum is a fungal pathogen that can result in a wide range of clinical presentations, from asymptomatic through fatal infection. It usually causes lung disease called Histoplamosis or Darling's disease Histoplasma capsulatum is a dimorphic ascomycete that grows in its hyphal form in soil and bird and bat guano. The natural habitat of capsulatum is the soil and has also been recovered most frequently from soil material contaminated with bird or bat droppings . Infection is most commonly seen via inhalation of organisms from soil contaminated with bird or bat droppings that contain the fungus Histoplasma capsulatum is an intracellular, thermally dimorphic fungi (grows as a yeast in body temperature/37°C in humans, mammals or in culture media and as mold in 25°C in environment/culture media) of medical importance that can survive within macrophages for an extended period. This fungal pathogen is associated with birds or bat droppings
CHARACTERISTICS: Histoplasma capsulatum is a dimorphic fungus (1). The filamentous mould form is found in the environment and can be cultured in conditions below 35ºC using general fungal media In histoplasmosis. >Histoplasma capsulatum, occurring in humans and other animals. The disease is contracted by the inhalation of dust containing spores of the fungus. H. capsulatum prefers moist, shady conditions and is found in woods, caves, cellars, silos, and old chicken houses. The droppings of certain types Histoplasmosis caused by Histoplasma capsulatum leads to a wide spectrum of symptomatology [1, 2, 3] varying from subclinical or acute to chronic form.Histoplasmosis can be localized or it causes a disseminated, life-threatening infection involving various tissues and organs of the body, notably in immunocompromised hosts [1, 4].This is a thermally dimorphic fungus presenting as a yeast at. Histoplasmosis is an intracellular mycosis of reticuloendothelial system It is a systemic infection involving lymphatic tissue, liver, spleen, Kidney, bone marrow and other body parts Also known as Cave dweller's disease or Darling disease or Reticuloendothelial cytoplasmosis or Ohio valley disease
. They float into the air when dirt or other material is disturbed. The fungus thrives in damp soil that's rich in organic material, especially the droppings from birds and bats Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. Symptoms of this infection vary greatly, but the disease affects primarily the lungs. Occasionally, other organs are affected; called disseminated histoplasmosis, it can be fatal if left untreated. Histoplasmosis is common among AIDS patients because of their suppressed immunity. In immunocompetent individuals, past infection results in partial protection against ill effects if reinfected. Histoplasma capsulatum is found i Histoplasmosis is a disease caused by an infection with a fungus known as Histoplasma capsulatum, which is common in the environment, most frequently in association with bird or bat droppings. Some people also refer to the disease as cave disease. The infection can cause a lung disease similar to pneumonia in some people Histoplasmosis, caused by the dimorphic environmental fungus Histoplasma capsulatum, is a major mycosis on the global stage. Acquisition of the fungus by mammalian hosts can be clinically silent or it can lead to life-threatening systemic disease, which can occur in immunologically intact or deficie
Histoplasmosis is an infection caused by a fungus called Histoplasma. The fungus lives in the environment, particularly in soil that contains large amounts of bird or bat droppings. In the United States, Histoplasma mainly lives in the central and eastern states, especially areas around the Ohio and Mississippi River valleys. The fungus also lives in parts of Central and South America, Africa, Asia, and Australia . The diagnosis is frequently missed, and outcomes historically have been poor.

Histoplasma capsulatum, or simply Histoplasma for short, is a dimorphic fungus capable of causing respiratory disease in humans. A dimorphic fungus can live in two different forms depending on. INTRODUCTION. Histoplasma capsulatum is a major human fungal pathogen on the global stage that causes disease in both immunocompetent and immunocompromised individuals, albeit the risk for severe disease increases with compromised immunity (e.g., in patients with HIV infection or cancer as well as in individuals receiving steroids or tumor necrosis factor alpha [TNF-α] blockers) Histoplasma strains and culture. Histoplasma capsulatum strains were derived from the wild-type strain G217B (ATCC 26032) and are listed in Table 1. Histoplasma yeasts were grown in Histoplasma-macrophage medium (HMM) or modified 3M medium (6, 46) lacking all vitamins except thiamine.Yeast cultures were grown with continuous shaking (200 rpm) at 37°C until late log/early stationary phase This page was last edited on 30 August 2020, at 02:59.

Reference Objective: Histoplasma capsulatum var. capsulatum infection is a major AIDS-defining illness in French Guiana.Although it affects South and Central American countries, the number of published cases is low. We present the largest series of AIDS-related histoplasmosis.The aim of this work is to describe clinical features and to help optimize investigations in settings where antigen detection. What is histoplasmosis? Histoplasmosis is a chronic, non-contagious fungal infection caused by the soil-dwelling fungus Histoplasma capsulatum.H. capsulatum is found globally and may infect both humans and animals. However, histoplasmosis is uncommon to rare in all but dogs and cats. The fungus thrives in warm moist environments and is commonly found in soil that contains bird or bat feces A thermal dimorphism was described for Histoplasma capsulatum with its virulent form growing at 37°C, the body temperature of many mammalian host species. In contrast, the saprobic phase grows over a broader temperature range, from 5-30°C and survives freezing [2, 3]

ABSTRACT Histoplasmosis is a systemic disease caused by the dimorphic fungus Histoplasma capsulatum, first described in 1905 by Darling after performing an autopsy on a native patient from Panama who had hepatosplenomegaly.. Histoplasma capsulatum is a soil saprophyte that grows well in soil enriched with bird droppings. The usual disease is self-limited, affects the lungs, and is asymptomatic. Chronic cavitary pulmonary disease, disseminated disease, and meningitis may occur and can be fatal, especially in young children and in immunosuppressed patients..
H. capsulatum is the etiologic agent of histoplasmosis, the most common pulmonary mycosis of humans and animals.(4) Forty million people in the United States are estimated to have been infected by H. capsulatum, with approximately 500,000 new infections occurring each year.(4) Asymptomatic or mild infections due to H. capsulatum are the rule. Histoplasmosis is an infectious disease of the lungs caused by a fungus, Histoplasma capsulatum. The infection can sometimes spread to other parts of the body. Droppings from chickens, pigeons, starlings, blackbirds, and bats support the growth of the fungus Histoplasma capsulatum.
