Bacteriology study of bacteria Mycology study of fungi Protozoology study of protozoa Phycology or algology study of algae Parasitology study of parasites Immunology . by Rebecca A. . Burns, . SUNY Canton, Canton New York . This . experiment was conducted to show the likelihood of contamination of a petri dish by bacteria when left exposed. The number of bacterial colonies that grew on exposed petri dishes were counted to determine the amount of contamination over a period of 1, 15, and 30 minutes. The number of . Serial dilution and colony counting. Also know as “viable cell counts”. Concentrated samples are diluted by serial dilution. The diluted samples can be either plated by spread plating or by pour plating. A. The body has two main mechanisms of defenses. 1. Innate defense mechanisms – first line of defense. A) These defenses are non-specific and . inherited. Immunity Overview. B) Examples:. 1. ) Physical barriers. The Good, the Bad, and the Ugly. Algae. Copepod. Amoeba. E. coli.
