The queen is the only ant that can lay eggs. The male antâs job is to mate with future queen ants and they do not live very long afterwards. Once the queen grows to adulthood, she spends the rest of her life laying eggs! Depending on the species, a colony may have one queen or many queens.
Streptococcal Infections (invasive group A strep, GAS) Last Reviewed: November 2011. Group A streptococci are bacteria commonly found in the throat and on the skin. The vast majority of GAS infections are relatively mild illnesses, such as strep throat and impetigo.
Two types of bacteria can cause strep throat: Group A (also known as Streptococcus pyogenes) and Group B. Each strain of bacteria can result in different complications. Strep bacteria are very contagious, and spread by nasal secretions and saliva. Strep throat most often afflicts children younger than 16, according to the Mayo Clinic.
