13. Isolamento e identificação de Coccidioides immitis de amostras de solo relacionadas a surtos de coccidioidomicose. / Isolamento and identification of Coccidioides immitis from soil samples related to outbreaks of coccidioidomycosis.
Coccidioidomycosis (CM) is a systemic mycosis that is endemic in the semi-arid Northeast of Brazil caused by the soil-inhabiting dimorphic fungus Coccidioides immitis non-CA [=C. posadasii]. In Brazil, the main epidemiological characteristic related to outbreaks of acute CM is the disturbance caused by armadillo hunters while digging them out of their infect

14. Análise do transcriptoma parcial do fungo Paracoccidioides brasiliensis recuperado após infecção de macrófagos peritoneais murinos
O fungo patogênico e dimórfico Paracoccidioides brasiliensis é o agente etiológico da paracoccidioidomicose, a micose sistêmica de maior prevalência na América do Sul. O fungo ocorre na natureza na forma de micélio, na temperatura de 26C, e na forma de levedura, na temperatura de 37C in vitro, sendo esta a forma encontrada nos tecidos de hospedeiros.

15. Clonagem e sequenciamento de um fragmento de DNA especÃfico de um isolado virulento de Paracoccidioides brasiliensis
Paracoccidioides brasiliensis is a dimorphic fungus and the etiologic agent of paracoccidioidomycosis, a systemic mycosis of acute or chronic evolution, which can be fatal if not diagnosed and treated. A molecular method for characterization and detection of P. brasiliensis was developed from cloning and sequencing of a DNA fragment of ~750 bp obtained by Ra

16. Coccidioidomycosis: an unusual cause of acute respiratory distress syndrome
A male farmer, 20 years old, from the countryside of the State of Piauí, developed acute respiratory infection. Despite adequate antimicrobial therapy, his conditions worsened, requiring mechanical ventilation. His X-rays showed diffuse pulmonary infiltrates. His PaO2/FiO2 ratio was 58. Direct microscopy and culture of tracheal aspirates showed the presence

17. Coccidioidomicose pulmonar em caçador de tatus
A coccidioidomicose, uma doença fúngica adquirida através da inalação do agente Coccidioides immitis sob forma de artroconídio, vem sendo descrita desde 1892. Restringe-se principalmente a áreas de clima árido, solo alcalino e regiões de baixo índice pluviométrico. Não por acaso, a maioria dos casos descritos no Brasil ocorreu na região Nordeste

18. Collagenolytic activity of Coccidioides immitis.
Coccidioides immitis appears to be unable to digest particulate collagen when cultured on collagen-containing semisolid culture media. However, all C. immitis strains solubilized collagen when the fungus was grown in liquid suspension cultures. Moreover, sterile culture filtrates were collagenolytic in collagen-buffer-agar plate assays.

19. Specificity of exoantigens for identifying cultures of Coccidioides immitis.
Forty-nine isolates of arthroconidial fungi other than Coccidioides immitis did not produce immunodiffusion lines of identity with the reference system for that fungus.

20. Limitation of the AccuProbe Coccidioides immitis Culture Identification Test: False-Negative Results with Formaldehyde-Killed Cultures
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 pr

21. Unusual Reducing Sugar from Coccidioides immitis
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.

22. Delayed-type hypersensitivity responses to a cell wall fraction of the mycelial phase of Coccidioides immitis.
A skin test-active fraction was isolated from the mycelial-phase cell walls of Coccidioides immitis. This alkali-soluble, water-soluble antigen (C-ASWS) elicited positive reactions in 22 of 24 (92%) of the Coccidioides-sensitized guinea pigs whereas only 14 (54%) of the same guinea pigs reacted to commercial coccidioidin (BioCox). None of the 21 Histoplasma-

23. Sugars and Amino Acids as Carbon, Nitrogen, or Energy Sources for Coccidioides immitis Spherules and Endospores
Of various carbohydrates and amino acids tested, glucose, mannose, fructose, and glutamate were the most efficient substrates metabolized by the endospores and spherules of Coccidioides immitis.

24. Characterization of 3-O-Methylmannose from Coccidioides immitis
3-O-methylmannose isolated from Coccidioides immitis was characterized by gas chromatographic comparison of derivatives with those of synthetic 3-O-methylmannose. Gas chromatographic behavior of three derivatives of the natural and synthetic sugars was identical.
