Of note is the Acinetobacter species baumannii which accounts for 80% of all reported Acinetobacter infections. Acinetobacter baumannii is isolated from a variety of infections - burns, respiratory ventilators, and trauma patients to name a few. One of the main reasons that this organism is so successful is it can persist for days on dry surfaces. It can also obtain nutrients from iron. It will stay on the surface of a bed rail or a tabletop until someone touches it and then colonization process begins. When... read more

Most students think biology is a drag. Contrary to everyone's belief, it is fun and meaningful. It takes the expertise of a biology tutor to show you how to easily learn and study this important subject. Understanding biology will help you for the rest of your life.

They do not have a chance to get an eduction, or have clean water or food or a place to live. You are lucky - you have the opportunity to learn! You will actually feel better about yourself once you study this subject. I welcome all comments. Have a great day!
