You could have an infection caused by bacteria, yeast, or viruses. Chemicals in soaps, sprays, or even clothing that come in contact with this area could be irritating the delicate skin and tissues. It's not always easy to figure out what's going on, though.
They produce over two-thirds of the clinically useful antibiotics of natural origin (e.g., neomycin, cypemycin, grisemycin, bottromycins and chloramphenicol). The now uncommonly used streptomycin takes its name directly from Streptomyces.treptomyces is the largest antibiotic-producing genus, producing antibacterial, antifungal, and antiparasitic drugs, and also a wide range of other bioactive compounds, such as immunosuppressants.
1 Genome sequence of the streptomycin-producing microorganism **Streptomyces griseus** IFO 13350 - http://jb.asm.org/cgi/content/abstract/190/11/4050 An A-factor-dependent extracytoplasmic function sigma factor (sigma AdsA) that is essential for morphological development in **Streptomyces griseus**.treptomyces griseus was most famously used to treat tuberculosis when Streptomycin was derived. from it in 1943 by Dr. Selman Waksman and co-workers. It can also be used to produce the anti-cancer drug streptocin and is now thought to be a good bacterium to use in the purifying of water.
