Not based on sex---many do not reproduce sexually 2. Some have "out of species" sexual transfer. We are evolving in our definition of species from highly similar in characteristics to a genetic definition. Also, strain is a subgroup of species. Characteristics of bacteria: 1. Morphological---have definite limitations for classification. Hundreds of species

Unformatted text preview: have the same morphology. 2. Chemical Characteristics: Cell Wall type currently defines Division. Another example are the sulphur bacteria with S present internally. Differential Staining can help with this. 3. Metabolic Characteristics. Fermenters, Citrate Utilizers, Catalase possessers, Urease possesers, Acetyl-methyl carbinol producers are all examples of metabolic characteristics we use in biochemical tests in the lab. 4. Genetic Testing. We can now, with the host of enzymes we possess, magnify and sequence DNA by a variety of methods. If we know the genome we will have an "exact" definition of species....
