Are disease causes by fungi. Are classified into three:

• Superficial infections; are localized to teratinized tissues such as skin, nails and hairs. Are caused by dermatophytes and candida albican.

• Subcutaneous infection; are limited to subcutaneous tissues though they may spread to the surrounding skin and bones.

• Systemic infections; occurs when pathogenic fungi enter the body and infact internal organs such as lungs, brains etc. are further divided into two mainly. Primary which occur in healthy individuals and opportunistic which occur in immunocom promised patients. Examples of opportunistic pathogens: Cryptococcusis, Aspergillosis, Systematic candiasis, pneumocystis (pcp).

Classification of Dermatophyte Infections: They were previously called tineas/ ringworms. Their growth is enhanced by foot and humid conditions, poor personal hygiene. Are classified as below;

• Tineacorpris e.g trichophytonrubrum and e.floccosum which affects their non hairly, smooth part of the skin.

• Tineapedis which affect el webs and the sole e.g I.rubrum and epidermophytonfloccossum.

• Tineacapitis of microsporuumcanis, trichophyton and mentagrophytes which affects el scalp.

• Tineacruris. Affects the grain e.g t.trubrum. e.floccosum and frichphytonmentagraphytes.

• Tineaungulium affects the board area e.g Trichophytonmentagraphytes.

• Tineamanuum. Affects the finger wbbs e.g tirubrum.
