Description:Bipolaris spicifera (Bain.) Subram.
Colony characteristics. Colonies (PCA) expanding, appearing glassy with sooty powder of conidia, or hairy if sporulation is poor.
Microscopy. Conidiophores erect, unbranched, septate, up to 250 µm long and 4-8 µm wide, regularly zig-zagged in the apical part, with flat, dark brown scars on the edges. Conidia brown, cylindrical with rounded ends, medium brown except for narrow subhyaline spots at the extremites, 20-40 x 9-14 µm, with 3 distosepta.
Teleomorph. Cochliobolus spiciferus Nelson (Ascomycota, Euascomycetes, Pleosporales: Pleosporaceae).
Pathogenicity. BSL-1. The species is a common saprophyte on plant material and in soil. It is frequently encountered as an agent of human or animal sinusitis (Sobol et al., 1984; Drouhet et al., 1985; Rolston et al., 1985; Adam et al., 1986; McGinnis et al., 1992; Schubert & Goetz, 1998), eventually with cerebral involvement (Young et al., 1978; Latham, 2000). Biggs et al. (1986) described a fatal cerebral case after head injury. Also cases of keratitis (Zapater et al., 1975; Forster et al., 1975b) and cutaneous phaeohyphomycosis (Estes et al., 1977) have been reported. Karim et al. (1993) described a pulmonary case and Pauzner et al. (1997) an endocarditis. Animal cases involved horses (Schauffer, 1972; Kaplan et al., 1975), cats (Müller et al., 1975), cows (Patton, 1977) and dogs (Hall, 1965; Kwochka et al., 1984).
