A coccidioidomicose é uma micose profunda causada por fungos dimórficos do gênero Coccidioides. As manifestações clínicas da infecção Coccidioides spp. podem ser bastante diversificadas. principal forma clínica a respiratória cujos sinais e sintomas mais frequentes são tosse, dispneia, dor torácica, febre, artralgia, mialgia, fadiga perda de peso. pulmonar, especialmente na sua manifestação com...

The AccuProbe Coccidioides immitis culture identification test (CI test) yielded false-negative results with formaldehyde-killed C. immitis submitted to a reference laboratory. Further evaluation with pure or mixed cultures or stored, heat-killed cultures revealed the CI test to be highly sensitive and specific for C. immitis except when the cultures were pretreated with formaldehyde.

Coccidioidomycosis (valley fever) is caused by the dimorphic fungi Coccidioides immitis or Coccidioides posadasii. Most infections are asymptomatic or result in self-limited pneumonia; extrapulmonary dissemination via either hematogenous or lymphatic spread is rare. Here, we present a case of cervical C. immitis lymphadenitis that resulted in fistula formation to the esophagus via mediastinal e...

Coccidioidomycosis ("valley fever") is caused by inhaling spores of the soil-dwelling fungi Coccidioides immitis or Coccidioides posadasii. Most infections are subclinical. When clinical manifestations do occur (typically 1-4 weeks after exposure), they are similar to those associated with influenza or community-acquired pneumonia. Disseminated disease is rare. Residual pulmonary nodules can le...

INTRODUCTION The increasing incidence of allogeneic transplants in Coccidioides-endemic areas such as the southwestern United States and Latin America highlights the importance of considering reactivation of donor coccidioidomycosis in transplant recipients. We report the case of a 42-year-old Nicaraguan woman who had multiple firm, violaceous subcutaneous nodules 1 month after her orthotopic l...

The X-ray structure of chitinase from the fungal pathogen Coccidioides immitis has been solved to 2.2 A resolution. Like other members of the class 18 hydrolase family, this 427 residue protein is an eight-stranded beta/alpha-barrel. Although lacking an N-terminal chitin anchoring domain, the enzyme closely resembles the chitinase from Serratia marcescens. Among the conserved features are three...

FROM THE PRECEDING I DERIVE THE FOLLOWING CONCLUSIONS: 1. The disease which formerly has been described as a form of protozoon-infection is due to an infection with a pathogenic fungus. 2. The infection may primarily be either a cutaneous or a pulmonary one. 3. The lesions produced by this fungus fall under the general head of infectious granulomata and consist partly in nodules resembling alto...

Documentation is offered for the identification of 3-O-methyl-mannose as one of several neutral sugars found in defatted arthrospore and mycelial cell walls of Coccidioides immitis.
