Abstract
We report a case of a 27-year-old male who presented with respiratory distress that required mechanical ventilation. Transbronchial biopsy revealed adiaspores of the fungus Emmonsia crescens within granulomata, a condition known as adiaspiromycosis. The patient received amphotericin products and corticosteroids, followed by itraconazole, and made a full recovery. Emmonsia crescens is a saprobe with a wide distribution that is primarily a rodent pathogen. The clinical characteristics of the 20 cases of human pulmonary adiaspiromycosis reported since the last comprehensive case review in 1993 are described here, as well as other infections recently reported for the genus Emmonsia. Pulmonary adiaspiromycosis has been reported primarily in persons without underlying host factors and has a mild to severe course. It remains uncertain if the optimal management of severe pulmonary adiaspiromycosis is supportive or if should consist of antifungal treatment, corticosteroids, or a combination of the latter two. The classification of fungi currently in the genus Emmonsia has undergone considerable revision since their original description, including being grouped with the genus Chrysosporium at one time. Molecular genetics has clearly differentiated the genus Emmonsia from the Chrysosporium species. Nevertheless, there has been a persistent confusion in the literature regarding the clinical presentation of infection with fungi of these two genera; to clarify this matter, the reported cases of invasive Chrysosporium infections were reviewed. Invasive Chrysosporium infections typically occur in impaired hosts and can have a fatal course. Based on limited in vitro susceptibility data for Chrysosporium zonatum, amphotericin B is the most active drug, itraconazole susceptibility is strain-dependent, and fluconazole and 5-fluorocytosine are not active.

Abstract
Disseminated adiaspiromycosis is a rare infection that is sometimes associated with immunocompromised situations. We report the case of a patient, infected with human immunodeficiency virus and receiving highly active antiretroviral therapy, who had a liver transplant for hepatocellular carcinoma. The patient presented skin and pulmonary lesions due to adiaspiromycosis during immunosuppressive therapy. A review of >60 cases in the literature shows that adiaspiromycosis is a rare infection and Emmonsia is a dimorphic fungus that is difficult to grow. It should be considered a possible diagnosis in case of fungal infection and pulmonary granulomatosis. We should be aware of emerging adiaspiromycosis in patients with risk factors of immunosuppression, particularly transplant recipients. In these patients in particular, liposomal amphotericin B therapy should be considered.

Abstract
Emmonsia crescens, a dimorphic fungus of the order Onygenales, is primarily a pathogen of lower animals and rarely humans. Inhaled conidia of E. crescens fail to germinate in the lungs, and instead simply enlarge in lung tissue to become giant adiaspores. We present here the case of fatal Emmonsia crescens infection in a wild-caught British water vole (Arvicola terrestris). Histopathological examination of the animal, which died in captivity, revealed a multifocally extensive granulomatous reaction containing oval adiaspores scattered irregularly throughout the lungs. Mycological examination of fungus cultured from lung tissue and PCR amplification and sequencing of rDNA gene fragments of the cultured organism confirmed the diagnosis of massive infection by E. crescens.

Abstract
A 64-year old farmer developed cough, dyspnoea on exertion, and recurrent febrile episodes. X-ray and CT scan revealed bilateral lower lobe opacities in his lungs. A transbronchial biopsy was performed and histopathological findings were interpreted as consistent with a pulmonary necrotizing clear-cell carcinoma and later as a Pneumocystis carinii pneumonia. Due to persistence of symptoms, six months later another lung biopsy was performed and a mould was cultured which was identified by 18S rDNA sequencing as Emmonsia sp. The patient showed some improvement under itraconazole treatment. This is the first description of a human infection with Emmonsia sp. in Germany.

Abstract
Two cases of human pulmonary adiaspiromycosis are reported. Patients were 29 and 54-year-old males, farm workers, with "grippe-like" symptoms and radiographic findings suggestive of granulomatous interstitial disease. Transthoracoscopic and transbronchial biopsies were performed. Pulmonary function was measured by spirometry. One patient used ketoconazole. Possibility of misdiagnosed pulmonary adiaspiromycosis is emphasized.

Abstract
The diagnosis of adiaspiromycosis is usually based on lung sections stained by hematoxylin-eosin, periodic acid Schiff and methenamine silver. Authors describe the fungus aspect examined by mucicarmin, picro-sirius and Congo red methods, including polarized light microscopy. In doubtful cases, these methods could contribute to histopathological diagnosis of Emmonsia parva var crescens.

Abstract
Fungal infections, especially those caused by opportunistic species, have become substantially more common in recent decades. Numerous species cause human infections, and several new human pathogens are discovered yearly. This situation has created an increasing interest in fungal taxonomy and has led to the development of new methods and approaches to fungal biosystematics which have promoted important practical advances in identification procedures. However, the significance of some data provided by the new approaches is still unclear, and results drawn from such studies may even increase nomenclatural confusion. Analyses of rRNA and rDNA sequences constitute an important complement of the morphological criteria needed to allow clinical fungi to be more easily identified and placed on a single phylogenetic tree. Most of the pathogenic fungi so far described belong to the kingdom Fungi; two belong to the kingdom Chromista. Within the Fungi, they are distributed in three phyla and in 15 orders (Pneumocystidales, Saccharomycetales, Dothideales, Sordariales, Onygenales, Eurotiales, Hypocreales, Ophiostomatales, Microascales, Tremellales, Poriales, Stereales, Agaricales, Schizophyllales, and Ustilaginales).

Abstract
We report the first case of Chrysosporium zonatum infection in a 15-year-old male with chronic granulomatous disease who developed a lobar pneumonia and tibia osteomyelitis while on prophylaxis with gamma interferon. The fungus was isolated from sputum and affected bone, and hyphae were observed in the bone by histopathology. Therapy with amphotericin B eradicated the osteomyelitis and pneumonia, but pneumonia recurred in association with pericarditis and pleuritis during therapy with itraconazole. These manifestations subsided, and no recurrences occurred with liposomal amphotericin B therapy. Infections caused by Chrysosporium species are very rare, and C. zonatum has not previously been reported to cause mycosis in humans. This species, the anamorph of the heterothallic ascomycete Uncinocarpus orissi (family Onygenaceae), is distinguished by its thermotolerance, by colonies which darken from yellowish white to buff, and by club-shaped terminal aleurioconidia borne at the ends of short, typically curved stalks. The case isolate produced fertile ascomata in mating tests with representative isolates. The median (range) MICs for our isolate as well as those for two other human isolates and a nonhuman isolate determined by the National Committee for Clinical Laboratory Standards method adapted for moulds were </=0.06 microg/ml (</=0.06 to 0.25 microg/ml) for amphotericin B, 0. 687 microg/ml (0.25 to 2 microg/ml) for itraconazole, >128 microg/ml (>128 microg/ml) for flucytosine, and 48 microg/ml (32 to >128 microg/ml) for fluconazole.

Abstract
Emmonsia crescens, an agent of adiaspiromycosis, Blastomyces dermatitidis, the agent of blastomycosis, and Histoplasma capsulatum, the agent of histoplasmosis, are known to form meiotic (sexual) stages in the ascomycete genus Ajellomyces (Onygenaceae, Onygenales), but no sexual stage is known for E. parva, the type species of the genus Emmonsia. To evaluate relationships among members of the putative Ajellomyces clade, large-subunit ribosomal and internal transcribed spacer region DNA sequences were determined from PCR-amplified DNA fragments. Sequences were analyzed phylogenetically to evaluate the genetic variation within the genus Emmonsia and evolutionary relationships to other taxa. E. crescens and E. parva are distinct species. E. crescens isolates are placed into two groups that correlate with their continents of origin. Considerable variation occurred among isolates previously classified as E. parva. Most isolates are placed into two closely related groups, but the remaining isolates, including some from human sources, are phylogenetically distinct and represent undescribed species. Strains of B. dermatitidis are a sister species of E. parva. Paracoccidioides brasiliensis and Histoplasma capsulatum are ancestral to most Emmonsia isolates, and P. brasiliensis, which has no known teleomorph, falls within the Ajellomyces clade.
