154 Gram Negative Oxidase Positive Fermenters VIBRIO 5. Aeromonas 1. Characteristics a. Motile by pola r flagella a. Curved rods with polar flagella b. Most are indole positive b. TCBS selective for vibrios c. Growth on MAC c. BAP - hemolytic colonies d. Cellulitis, wound infections and d. Lactose negative ( differs from diarrhea enterics) e. N03 positive (NO3 to NO2 ) OTHER ORGANISMS 2. V. cholera (Serogroup 01) 1. Campylohacter jejuni a. Gastroenteritis - rapid onset 3-10 a. Small curved rods, "seagull hrs.; profuse diarrhea appearance" (light staining) b. Need high concentration of b. Microaerophilic, 2-4 days for organism unless hypochlorohydric growth c. Stools contain mucu s fleck s c. Growth on CAMPY agar (described as "rice water" stools) d. Found in raw poultry and d. Yellow on TCBS contaminated water (like Salmonella) 3. V. parahemolyticus e. Erythromycin or tetracycline for a. Green on TCBS treatment b. Enteritis f. Bioch emical reactions ❖ Catalase positive 4. V. vulnificus ❖ Oxidase positive a. Gr een on TCBS ❖ Hippurate positive b. Septicemia - can kill immunocompromised or diabetics 2. Helicobacter pylori a. Associated with gastric and duodenal ulcers b. Produces large amounts of urease Campylobacter jejuni Just call me Jay June Eye. I might be in water or chicken pot pie. I like just a touch of o2 More oxygen and I'll be through! Campy-plates are best to grow _ At 42 degrees or so If I grow, Gram stain me And curved rods are what you'll see.
