“…Subsequently, it has been recovered from many different plants as well as soil, textiles and other substrates in Africa, Asia, the Caribbean island of Jamaica and the South Pacific islands of New Caledonia. Subsequent to the first known case cited above, 10 other human cases of infection by B. hawaiiensis have been described up to the present in the world's literature; Europe [36], India [5,37], South Africa [97] and the United States [43,54,63,95,96].…”

In this era of the widespread use of broad-spectrum antibiotics, corticosteroids, cytotoxic agents and other immunosuppressants, coupled with the increasingly stressful life styles demanded by modern civilization, it is hard to draw a sharp line between pathogenic and non-pathogenic fungi. Most of the moulds and yeasts, whether primary pathogens, or opportunistic, allergenic or toxigenic fungi, occur in nature as soil-dwelling saprobes or plant pathogens from where they are released into the air. Fungal infections observed in susceptible hosts, in the main, are actually acquired from their own surroundings. While substantial attention has been paid to the occurrence of well-recognized agents of classic mycotic diseases, the health implications of common environmental fungi have drawn relatively less attention. The objective of this communication is, therefore, to examine various aspects of environmental mycology in relation to human health. Since fungi of any serious economic importance are seldom at home in water, this communication does not address aquatic fungi. Instead food, which is frequently affected by fungi and in turn profoundly affects human health, has been included. Relationship of fungi to the sick building syndrome and building related illnessesThe 'sick building syndrome' (SBS) and 'building related illnesses' (BRI) may be characterized as phenomena that gained recognition in North America as a public health problem after this region had experienced several energy crises. The quest to make large buildings more energy efficient resulted in reduced air exchange with the outdoors. As a result, indoor concentrations of tobacco smoke, carbon monoxide, nitrous dioxide, and volatile organic compounds, such as formaldehyde and tetrachloroethylene, either singly or in combination, increased. These chemical factors are probably the most common causes of occupant complaints leading to a SBS designation for a particular structure [64,65]. As yet there are no sets of standards for defining SBS and BRI. In general 'substantial' numbers of complaints of headaches, flu-like symptoms, difficulty in breathing, or of burning eyes by inhabitants are

“…The discharge of ascospores of C. geniculatus is through splitting of ascus (Alcorn 1981a) which is somewhat different from the generic type species C. heterostrophus where ascospores are released though a swelling of the ascus and circumcessile rupture in the epical portion of the ascus wall (Alcorn 1981a (Subramanyam et al 1990) and has been recorded as a weak pathogen and a saprobe associated with rotten rice kernels and seeds of Cajanus cajan. It has been recorded as a human pathogen causing phaeohyphomycosis (Costa et al 1991) such as nasal phaeohyphomycosis (Koshi et al 1987) and Corneal ulcer (Anandi et al 1988). Bipolaris hawaiiensis cause sinusitis and is more aggressive than the other hyphomycete pathogens which cause sinusitis (Fothergill 1996).…”

Cochliobolus: an overview and current status of species

The genus Cochliobolus (anamorphs Bipolaris, Curvularia) comprises many destructive plant pathogens that cause severe crop losses worldwide. The taxonomy of Cochliobolus is confused as frequent nomenclatural changes have occurred in the sexual and asexual states of species over the past 50 years. We provide an overview of these nomenclatural changes together with a morphological circumscription of the genus. Taxonomic notes and information about the life history of 55 species epithets of Cochliobolus listed in Index Fungorum are also given. Further information is given concerning the location of type cultures; availability of DNA sequence data derived from type cultures; mode of life; novel metabolite production; and use of Cochliobolus species in biocontrol. We provide a multilocus phylogenetic tree based on DNA sequence data derived from 25 ex-type and authentic cultures that shows the group as monophyletic. This paper represents the first comprehensive overview of Cochliobolus since 1987, including a summary of applications of species and molecular phylogenetic research. The 55 species of Cochliobolus are listed alphabetically, with synonyms, hosts and diseases, brief notes concerning taxonomic and phylogenetic research.

“…Bipolaris species as an aetiological agent is probably more common than is generally appreciated. The three most common species – B. spicifera , B. hawaiiensis and B. australiensis have all been reported as causative agents of mycotic keratitis 9, 10 . In fact Bipolaris keratomycosis has also been reported from borderline lepromatous leprosy from south India 9 .…”

A case of mycotic keratitis caused by Bipolaris spicifera is reported. The corneal ulcer developed after 1 week of treatment with corticosteroids and antibiotics. Septate, branched, dematiaceous hyphal elements were detected in the corneal scrapings on two occasions and repeated cultures were positive for this fungus. The infection was resolved with natamycin and itraconazole although the corneal opacity remained and the patient is now waiting for a keratoplasty.
