Table 1: _Cont._Surface appendages used in motility such as flagella and pili are also identifying features in bacteria. Flagella are filamentous surface appendages that are 3 to 12 um in length and 12 to 30 nm in diameter while pili are thin hair-like appendages that are variable in length and are 6-7 nm in diameter. [18] Flagella can be monotrichious (one flagellum), lophotrichious (multiple flagella) at one pole, amphitrichious (a single flagellum at either pole) or peritrichious (multiple flagella around the entire bacteria) [20]. Pili, on the other hand, fall into two categories, sex pili, which usually consist of 1-6 long fimbiae, and Type IV pili, which can consist of hundreds of short fimbiae distributed over the entire bacteria surface. Decision Tree Analysis for Morphological Identification of an Unknown Bacteria: To classify and analyze morphological data collected on airborne bacterial pathogens, an excell-based decision matrix was designed and developed as a decision tree. The components to produce this decision tree consist of \"IF Statements\", drop-down menus, airborne bacteria, and phenotypic characteristics. There are seven observable characteristics (Table 1) that contain two to six identifiers in each of their drop-down menus. The drop-down menus are essential to input characteristics after identifying and analyzing an ambient air sample. The \"IF Statement\" function is used to produce one value when the provided statement is true and another value when the provided statement is false. With these functions, the output is very specific in listing the scientific name(s), i.e., and the identity of the pathogen that has been collected.
