The initial procedure was done to isolate pathogen from patient normal microbiota or other contaminants via plate streaking on four selective and differential media namely: Mannitol salt agar (MSA) to inhibit the growth of most organisms and differentiate possible pathogenic staphylococci, Phenylethyl alcohol (PEA) agar to grow gram-positive organisms, Eosin methylene blue (EMB) agar to cultivate gram-negative bacteria and isolate fecal coliforms, and Nutrient agar for a general purpose to support the growth of the unknowns. All plates were incubated at 35˚C for 24 to 48 hours. Bacterial growth, colony-descriptions, colonies and plates color and color changes were observed, recorded, and pictures were taken as well. Subculture was done for the two organisms that were isolated from these four media through streak plate method onto nutrient agar plates. Gram stain performed on each young subculture of unknown bacteria (less than 24 hours old) for an accurate results and the first important step to identify the
