Two different surveys, one strictly epidemiological in rural areas, the other retrospective and within hospitals, led to a better knowledge of the setting of the FLD and BBD in South Pyrenees region. In the country, more than 12% of patients had specific precipitins, 6% had either one or both diseases; women had anti-aviary precipitins more frequently than men. The retrospective hospital survey yielded 456 cases of patients admitted or consulting revealing numerous correlations between the different clinical, radiological and functional syndromes on the one hand and the serological positivity on the other. Serological diagnosis was most useful, as a wide variety of antigenic extracts was used (actinomycetes thermophiles, mouldy hay, bird droppings), mixed sensitizing was extremely frequent. The widely found positivity towards avian antigens seems specific to the South Pyrenees region.

In a patient properly treated for a previous cavitary tuberculosis, we had the surprise, after hemoptyses, to find a sleigh-bell shaped picture suggesting an intra-cavitary aspergilloma with a very special mycosis with Allescheria Boydii. Proof was provided by the presence of the fungus in direct examination and in culture in bronchial secretions. Surgical exeresis did not cure the patient and a secondary recurrence appeared on which antifungal drugs were ineffective. Antigens were made from the strain. They are used for immunoprecipitations tests. Only the patient's serum is positive; 82 serum test (18 concerned patients with visceral mycosis of farmer's lung disease) remained negative. Twenty two observations or pulmonary allescheriosis were recorded in the world. These figures are certainly below the truth. Three practical consequences can be drawn: --for an intra-cavitary mycetoma, with negative anti-aspergillus precipitins, such a disease must be kept in mind and the fungus looked for in bronchial secretions and specific immuno-precipitation test done; --any mycotic growth must be systematically cultured to determine the type of fungus; --for therapy, if diagnosis was made before the intervention, an antifungal treatment either local or general must be associated to the surgical treatment (contrary to aspergilloma treatment).

Mucormycoses are rare, acute infections, most often fatal, occurring usually in a host with decreased immunity. The agents are ubiquitous fungi belonging to the Mucoraceae family, an ordinary saprophyte becoming pathogenous in patients with a severe disease (malignant hemopathy, diabetes) or treated by immunosuppressive drugs. Pulmonary localizations remained exceptional (128 cases found in the literature). The observations reported draws its originality from: -- the etiological circumstances: an aged patient with no hemopathy or diabetes, without immunosuppressive treatment but undergoing a prolonged antibiotic therapy; -- the clinical signs: discovery on X-ray of excavated infiltrates in a background of a severe infection with a very poor physical condition; -- the diagnosis criteria with the demonstration of the responsible mucor in the sputum, the endobronchial aspiration and transparietal puncture; -- the great efficiency of Amphotericin B at rather small doses. A review of the literature underlines the exceptional character of the cure.
