  • Image 3. Pigmentation of Aspergillus versicolor colonies ranged from pale green to greenish-beige, pink-green, dark green and brown. Reverse is usually reddish. The growth rate is usually slow. Cultured on Sabouraud dextrose agar with chloramphenicol.

  • Image 4. A. versicolor by microscopy showing very long thin conidiophores.

  • Image 5. A 66 yr old patient in good general health developed onychomycosis. Samples taken from the affected nail were grown by culture and examined by microscopy.

  • Airways invasive aspergillosis in Patient with AML

    This 24-year-old male with AML on chemotherapy developed recent onset fever and cough. B- Representative section of High Resolution CT shows centri-lobular nodules, ‘tree-in-bud’ appearance consistent with bronchogenic spread of disease.

  • Airways Obstructing bronchial aspergillosis with aspergillus bronchitis

    This man with severe chronic fibrosing alveolitis underwent a single left lung transplant at the end of November 2004. Postoperatively he developed reperfusion pulmonary oedema and was difficult to ventilate. He also developed acute renal failure requiring haemodialysis/haemofiltration which corrected his fluid overload and rising creatinine.Rejection was prevented with cyclosporin, mycophenolate and a decreasing dose of methylprednisolone. Cardiovascular problems identified mild pulmonary anastomostic stenosis with a 5% pressure gradient. He had a tracheostomy about 12 days post transplant. He then developed episodes of hypoxia and increased ventilatory pressures. Several bronchoscopies showed mucus plugging in the trachea and major bronchi. These were aspirated, with improvement of oxygenation. Cultures of one of these plugs grew A. fumigatus. These images show a bronchoscopy view of the trachea and anastomosis. Major obstruction of the airway is visible (70%) distal to the anastomosis which looks healthy. Some evidence of tracheal inflammation is visible.

  • Figure illustrating Aspergillus tracheobronchitis in a normal child

    Aspergillus tracheobronchitis in a normal child. This figure, drawn in 1890, illustrates the appearances of the trachea and main bronchi at autopsy in a 3 year old child. She had little else wrong at autopsy other than a minor degree of tuberculosis. She is the first recorded case of Aspergillus tracheobronchitis in the literature and illustrates well that this disease can affect previously well non-inimmunocompromised people. The full case is reported in Wheaton SW.
