Chytridiomycosis caused by the fungus B. dendrobatidis predominantly affects the outermost layers of skin containing keratin. When most species reach a B. dendrobatidis threshold of 10,000 zoospores, they are not able to breathe, hydrate, osmoregualte, or thermoregulate correctly.ange [edit]. The geographic range of chytridiomycosis is difficult to ascertain. If it occurs, the disease is only present where the fungus B. dendrobatidis is present. However, the disease is not always present where the fungus is.
Though it's commonly called an employer Identification Number (EIN), there are times when you may need an EIN even though you do not have employees. An EIN can be used to identify a business entity that is legally separate from yourself, such as your corporation, partnership or retirement plan.

The IRS uses the EIN to identify the taxpayer. EINs must be used by business entities--corporations, partnerships, and limited liability companies. However, most sole proprietors don't need to obtain an EIN and can use their Social Security numbers instead. Even so, you may want to obtain an EIN anyway.
