disease that was seen in women after childbirth 4) Streptococci are classified into the alpha, beta, or gamma groups, according to
their action on blood cells 5) It leaves a purple stain during the gram test

Good Citizen
The Good Citizen Award is being given to Lactobacillus acidophilus. This gram-positive, rodshaped, and non-motile organism has helped their community in many ways. We must thank L.
acidophilus for “souring” milk, cheese, and yogurt. Lactose and intolerance people really appreciate this
citizen since they are the producer of sweet acidophilus milk. An important contribution that L.
acidophilus has contributed to society is its ability to help restore the normal balance of intestinal
bacteria. This ceases diarrhea. There are no known side effects, toxicity, or interactions associated with
L. acidophilus which makes it the perfect recipient for the Good Citizen Award.
