Phytophtora is a fungus initially attacks stems and leaves, causing grey-green blotches to appear, which later turn brown. It spreads via spores, which produce germ tubes to penetrate the plant tissue. Phytophthora is washed into the soil by rain, where it also infects the tubers. A single infected tuber is enough to destroy an entire crop.
Phytophthora citricola was created in 1927.
Phytophthora inflata was created in 1949.
Phytophthora kernoviae was created in 2003.
Phytophthora alni was created in 1995.

It depends on which type of potato blight you are referring to.Early blight -- caused by Alternaria solani, a fungal pathogen.Late blight -- caused by Phytophthora infestans, an oomycete.
Two errors in this question: 1. bacteria is plural, hence "Do ...bacteria..." would be correct. 2. Phytophthora is not a bacterium, but a eukaryote. And yes, they need oxygen.
