“…Since then, and as a result of increased knowledge of variation in fungi, further advances in the taxonomy of Fusarium species have occurred. Other taxonomic systems have been proposed by Gerlach and Nirenberg (71), Raillo (182,183), Bilai (23,24), Joffe (97), Snyder and Hansen (209)(210)(211), Messiaen and Cassini (138), Matuo (133), Gordon (73)(74)(75)(76)(77)(78)(79)(80), Booth (28), and Nelson et al (154), and these will be discussed in detail later in this paper. It is essential to remember that all so-called modem systems of Fusaium taxonomy are based on the work of Wollenweber and Reinking (255).…”

“…In their opinion, these changes were justified because many of the varieties and forms may have been cultural variants or mutants. The publication of Nelson et al (154) is illustrated with photographs of macroconidia, microconidia, conidiophores, and chlamydospores produced on carnation leaf agar (54 Gordon (78,80), and Booth (28) (Fig. 22) and the mode of formation, whether it be singly, in false heads only, or in false heads and chains (Fig.…”

Taxonomy, biology, and clinical aspects of Fusarium species

There are several taxonomic systems available for identifying Fusarium species. The philosophy used in each taxonomic system is discussed as well as problems encountered in working with Fusarium species in culture. Fusarium species are toxigenic, and the mycotoxins produced by these organisms are often associated with animal and human diseases. The implications for the association of the carcinogens, fumonisins, produced by Fusarium moniliforme and other Fusarium species with human diseases are discussed. Foreign-body-associated fusarial infection such as keratitis in contact lens wearers, onychomycosis, skin infections, and disseminated multiorgan infections are discussed. Disseminated fusarial hyalohyphomycosis has emerged as a significant, usually fatal infection in the immunocompromised host. Successful outcome is determined by the degree of immunosuppression, the extent of the infection, and the presence of a removable focus such as an indwelling central venous catheter. These infections may be clinically suspected on the basis of a constellation of clinical and laboratory findings, which should lead to prompt therapy, probably with one of the newer antifungal agents. Perhaps the use of such agents or the use of colony-stimulating factors may improve the outcome of this devastating infection. However, until new approaches for treatment develop, effective preventive measures are urgently needed.

“…The classification proposed by BOOTH (1977) for the identification of Fusarium species was adopted for the present study. This classification is based on GORDON's (GORDON 1960), as this uses a large number of parameters and it provides an information more complete of the studied species. This classification system is easy to handle, the morphology of spores being one main feature in the identification according to BOOTH (1971BOOTH ( , 1977.…”

A group of 49 strains of Fusarium sp. isolated from different Spanish samples of cereals and mixed feedstuffs were screened for their ability to produce trichothecenes like T‐2 toxin (T‐2), HT‐2 toxin (HT‐2), diacetoxyscirpenol (DAS) and deoxynivalenol (DN), as well as other mycotoxin produced by Fusarium named fusarin C. The production of these mycotoxins was analyzed by means of spectro‐photometry, thin layer chromatography (TLC), high performance liquid chromatography (HPLC) and gas chromatography (GC). Results showed that from 19 Fusarium strains in which cultures trichothe‐cene production was detected, 15 were HT‐2 producers, 9 T‐2 producers, 14 DAS producers and 10 DN producers. On the other hand, from 28 Fusarium strains in which cultures fusarin C production was detected, 22 were low fusarin C producers (ranged from 0.04 to 1 μg/l ICI medium), 5 Fusarium strains were intermediate‐level producers (ranged from 1 to 10 μg/l ICI medium) and one Fusarium strain produced 240 μg/l ICI medium. The identified Fusarium strains that produced trichothecenes and fusarin C were F. moniliforme and F. oxysporum.

The mycelial growth of 10 Fusarium culmorum strains isolated from water of the Andarax riverbed in the provinces of Granada and Almeria in southeastern Spain was tested on potato-dextroseagar adjusted to different osmotic potentials with either KCl or NaCl (−1.50 to −144.54 bars) at 10 • C intervals ranging from 15 • to 35 • C. Fungal growth was determined by measuring colony diameter after 4 d of incubation. Mycelial growth was maximal at 25 • C. The quantity and capacity of mycelial growth of F. culmorum were similar at 15 and 25 • C, with maximal growth occurring at −13.79 bars water potential and a lack of growth at 35 • C. The effect of water potential was independent of salt composition. The general growth pattern of Fusarium culmorum growth declined at potentials below −13.79 bars. Fungal growth at 25 • C was always greater than growth at 15 • C, at all of the water potentials tested. Significant differences were observed in the response of mycelia to water potential and temperature as main and interactive effects. The number of isolates that showed growth was increasingly inhibited as the water potential dropped, but some growth was still observable at −99.56 bars. These findings could indicate that F. culmorum strains isolated from water have a physiological mechanism that permits survival in environments with low water potential. Propagules of Fusarium culmorum are transported long distances by river water, which could explain the severity of diseases caused by F.culmorum on cereal plants irrigated with river water and its interaction under hydric stress or moderate soil salinity. The observed differences in growth magnitude and capacity could indicate that the biological factors governing potential and actual growth are affected by osmotic potential in different ways.
