“…Mating types. Although Horie et al (10) described heterothallism in N. udagawae and designated CBS114217 and CBS114218 as the type strains of the two opposite mating types, their MAT genotype was not identified. Subsequently, Varga et al arbitrarily assigned CBS114217 and CBS114218 to be mating type A and mating type a strains, respectively (30).…”

“…Neosartorya udagawae, a heterothallic ascomycete with an Aspergillus fumigatus-like anamorph, was described in 1995 (10). The species description was based on two strains with opposite mating types, strains CBS114217 and CBS114218, isolated from the soil of a Brazilian sugar cane plantation (10).…”

A recent report on several cases of invasive aspergillosis caused by Neosartorya udagawae suggested distinctive patterns of disease progression between N. udagawae and Aspergillus fumigatus. This prompted us to characterize N. udagawae in comparison to A. fumigatus. Our findings showed that both species exist in two mating types at similar ratios and produce gliotoxin. However, the thermotolerance of the two species differs: while A. fumigatus is able to grow at 55°C but not at 10°C, N. udagawae is able to grow at 10°C but fails to grow at >42°C. Furthermore, compared to A. fumigatus, the conidia of N. udagawae require longer incubation periods to germinate at 37°C and are more susceptible to neutrophil attack as well as hydrogen peroxide; N. udagawae is also less virulent in gp91 phox؊/؊ mice. These findings suggest that growth and susceptibility to the host response might account for the reduced virulence of N. udagawae and the subtle distinction in the progression of the disease caused by the two species.

“…Aspergillus flavus, A. fumigatus, Aspergillus terreus, and Aspergillus niger (14) and, less frequently, Aspergillus tamari (12), Aspergillus nomius (16), Aspergillus tubingensis (13), and Aspergillus brasiliensis (15) have been isolated from keratomycosis cases. In contrast, N. udagawae, an ascomycete with an A. fumigatus-like anamorph (21), originally identified from Brazilian soil (11) and only recently implicated in cases of invasive aspergillosis (25), has not yet been reported from mycotic keratitis.…”

We report the first documented case of a posttraumatic fungal keratitis caused by Neosartorya udagawae. The patient was empirically treated with fluconazole until a corneal scraping grew an Aspergillus fumigatus-like fungus, and itraconazole therapy was then established. A sequence-based approach assigned the isolate to the species. Five months after completion of antifungal therapy, endophthalmitis occurred and orbital exenteration was necessary.

“…The second isolate, 01-BA-739-2, is characterized by production of broadly lenticular ascospores with four equatorial crests and rugulose surfaces on the convex walls. These isolates proved to be sufficiently different from all described species of Neosartorya (Horie et al 1992(Horie et al , 1995a(Horie et al ,b, 2001Kong 1997;Kozakiewicz 1989;Kwon-Chung and Kim 1974;Malloch and Cain 1972;Peterson 1992;Raper and Fennell 1965;Samson et al 1990;Someya et al 1999;Takada and Udagawa 1985;Takada et al 2001;Udagawa and Takada 1985;Udagawa et al 1991Udagawa et al , 1993Yaguchi et al 1994).

Neosartorya indohii and N. tsurutae, two new Neosartorya species isolated from tropical rainforest soil in the Amazonian area, Brazil, are described and illustrated. Neosartorya indohii is characterized by its spreading growth on Czapek's and malt extract agars, light yellow cleistothecia, broadly lenticular ascospores with two conspicuously serrate-incised equatorial crests and tuberculate convex surfaces, and globose to subglobose conidia with a smooth wall. Neosartorya tsurutae is characterized by its spreading growth on Czapek's and malt extract agars, white cleistothecia, broadly lenticular ascospores with four equatorial crests and rugulose-ruminate convex surfaces, and ovoid to broadly ellipsoidal conidia with a smooth wall.
