Fusarium oxysporum
• It is a anomorphic species,include both pathogenic and nonpathogenic strain
• it is a chemoorganoheterotroph, meaning that it obtains its energy from chemicals (chemotroph), uses organic substrates like lactate and acetate as electron donors (organotroph), and obtains it's carbon from organic sources (heterotroph).
• It is a saprophyte, or a heterotroph that can obtain nutrients by consuming detritus (decomposing organic matter).

Appearance mycelium is initially white but later becomes purple, They can also be hyaline (glass- like, transparent), dark blue, or dark purple. F. oxysporum …show more content…

oxysporum appears to be cosmopolitan .
• Distribution maps show that this fungus has invaded North and South America, Europe, Africa, Asia, and Oceania.
• A ubiquitous soil fungus, the optimum soil temperature for root infection is 30°C or above but infection through the seed can occur at temperatures as low as 14°C, although it grow optimally at 28°C .
• It is pathogenic to humans,so the human body is a secondary habitat.

Ecology and Pathogenesis
Fusarium oxysporum has many Formae speciales that exist as plant pathogens, which are differentiated by host range, causing storage, root, stem, and fruit rot, as well as vascular wilt.they are also important mycotoxin (toxic metabolite) producers. These various special forms infect certain crops:
• F. oxysporum f.sp. cubense - Banana wilt
• F. oxysporum f.sp. vasinfectum - wilt of cotton
• F. oxysporum f.sp. batatas - wilt of sweet potatoes and stem rot
• F. oxysporum f.sp. lycopersici - tomato wilt
• F. oxysporum f.sp. asparagi - asparagus wilt
• F. oxysporum f.sp. melonis - muskmelon and cantaloupe wilt
• F. oxysporum f.sp. zingiberi - ginger
