Abstract A description is provided for Aspergillus sydowii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Primarily a soil species (DOMSCH et al., 1980), but also isolated from other substrata, including wallpaper, talc, paint and cotton yarn (CABI BIOSCIENCE, 1999). DISEASE: On man isolated from keratomycosis (mycoses), bones, joints, lungs and the central nervous system (SMITH, 1989). In addition it has been isolated from onychomycosis (SUMMERBELL et al., 1989), from AIDS patients (NEVES et al., 1998) and as component of hospital air mycoflora (GOODLEY et al., 1994). GEOGRAPHICAL DISTRIBUTION: World-wide.

Abstract A description is provided for Filobasidiella neoformans. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Bird droppings, particularly pigeon droppings, and soil contaminated with droppings are the best known source of F. neoformans in the environment. In addition to man, naturally-acquired infections have been recorded in the baboon, buffalo, cat, cattle, cheetah, civet, dog, fennec, ferret, fox, goat, guineapig, horse, koala, mink, monkeys, mouse, ox, peccary, pig, hare and sheep (causing mycoses). Experimental infection can be regularly produced in laboratory animals, mice being the animals of choice for most experimental work. DISEASE: Cryptococcosis (torulosis, European blastomycosis, Busse-Buschke's disease). This is a subacute or chronic pulmonary disease with a marked tendency to spread to the brain and sometimes other organs. The pulmonary form is usually transitory, mild and unrecognized. Cutaneous, skeletal and visceral lesions may occur during dissemination of the disease. Involvement of the central nervous system with meningoencephalitis is both the most common localization and the most common cause of death from the disease. Cryptococcosis of the central nervous system is invariably fatal unless treated. The symptoms of central nervous system Cryptococcosis are headache, nausea, dizziness, impaired memory, irritability, lethargy, ataxia and sometimes nuchal rigidity. Fever is low grade or absent. If the cranial nerves are involved, the patient may experience facial numbness or weakness or diplopia. The duration of the disease varies from a few weeks to 15 or 20 years. In cattle, cryptococcal mastitis is a not uncommon disease. GEOGRAPHICAL DISTRIBUTION: Worldwide.

Abstract A description is provided for Aspergillus flavus. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Found in soils, decaying vegetation, cereals, nuts, spices, etc. (Kozakiewicz, 1994). DISEASES: On insects: Frequently found on corn earworms, corn borers (Domsch et al., 1980), bee larvae, locusts, termites, insect scales etc (IMI, 1992). On man: Causes invasive lesions of the orbit, particularly in hot, dry geographic regions. It has also been isolated from human skin, nails, bones, the central nervous system and lungs (Smith, 1989). GEOGRAPHICAL DISTRIBUTION: Worldwide, but it is predominantly a tropical and subtropical species.

Abstract A description is provided for Absidia corymbifera. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: A common saprophyte in soil, compost and vegetable debris but also pathogenic for man and warm-blooded animals (causing mycoses). DISEASES: This species is a common cause of phycomycosis (syn. 'mucormycosis'). Infection in man may involve the central nervous system (RMVM 1, 341), ear (1, 473) or lung (5, 159); see also Dodge (1936), p. 112; Emmons et al. (1963), p. 194. In cattle it is a cause of mycotic abortion (Ainsworth & Austwick (1959), p. 53; 4, 507) and has been recorded in the rumen (4, 1850), causing abomasal ulcers (Gitter & Austwick, 1959) and also lymph node infection (3, 134). In the guineapig, A. corymbifera can cause an enlargement of the lymph nodes which simulates pseudotuberculosis (2, 1721; Ainsworth & Austwick (1959), p. 48). Infection of mink, fowl (Ainsworth & Austwick (1959), pp. 48-49) and the pig (3, 1249) have been recorded, as has experimental infection of mice (2, 1917). GEOGRAPHICAL DISTRIBUTION: World-wide. TRANSMISSION: Infection occurs from airborne spores which are a characteristic component of the airspora of farm buildings.
