Bacterial infections and noninfectious inflammatory conditions also may cause encephalitis. An infection may result in one of two conditions affecting the brain: 1  Primary encephalitis occurs when a virus or other infectious agent directly infects the brain. 2  The infection may be concentrated in one area or widespread. There are two types of herpes simplex virus (HSV). 2  Either type can cause encephalitis. 3  HSV type 1 (HSV-1) is usually responsible for cold sores or fever blisters around your mouth, and HSV type 2 (HSV-2) commonly causes genital herpes.
The wolf spider is often mistaken for a tarantula because it is similar in appearance. Wolf spiders are also mistaken for nursery web spiders, but wolf spiders do not spin webs and their bodies are more robust than nursery web spiders, which are generally thin with pointed rear ends.
Wolf Spiders are NOT poisonous, every spider has venom but only a few of them can affect humans. People mistake them for brown recluses and hobo spiders. Hobo spiders don't live on the ground, and if there is one on the ground it's most likely a male.They live in hammock shaped funnel webs in corners. just realized that this video has over 9000 views.... thanks guys! :D.
