About the cover: The background of the cover is an electron micrograph of Staphylococcus aureus and its secretion of a polysaccharide that increases the virulence of this microbe. When these bacteria secrete this matrix, they can decrease the ability of immune cells like neutrophils to attack and destroy them. Credit for the picture is given to Dr. Albert Guidry, Dr. William Wergin, and Mr. Eric Erbe, all associated with the U.S. Department of Agriculture, Agricultural Research Service at Beltsville, Maryland.
