
Infectious disease

An illness due to a specific infectious agent or its
toxic products that arises through transmission of
that agent or its products from an infected person,
animal or reservoir to a susceptible host, either
directly or indirectly
Overview
 Fungi
 Microorganisms that can infect various tissues of
animals
 Called
 Mycoses
 Mycotic infections
 Fungal infections
 Single organism – fungus
 Multiple organisms – fungi
 Affect
 Superficial skin
 Various body systems
