Cholera Hides in Biofilm
"The germ that causes cholera (Vibrio cholerae) forms a biofilm that enables it to survive in the presence of chlorine in concentrations 1000 to 2000% higher than that found in chlorinated drinking water."

Hyphae (mycelium) of Trichophyton rubrum. Trichophyton rubrum is an anthropophilic dermatophyte. Dermatophyte fungi infect keratinized tissues (skin, nails, hair) in humans and other animals. The downy strain of T. rubrum has become the most widely distributed dermatophyte of humans. It frequently causes chronic infections of skin, nails and rarely scalp. The granular strain is a frequent cause of tinea corporis in South East Asia and in Aborigines living in the Northern Territory of Australia. However, since the Vietman War, it has been spread throughout the world. The thread-like structures are hyphae, the vegetative filamentous cells of this fungus. This hyphal stage is the saprophytic stage of the fungus. Fungal growth is usually confined to tips of hyphae, where asexual reproduction occurs by spore formation. Dermatophytes preferentially inhabit the nonliving, cornified layers of the skin, hair, and nail, which is attractive for its warm, moist environment conducive to fungal growth. Other species of Trichophyton can cause disease in humans, inhabiting the skin, nails and scalp.
