What are the 3 oral Gram + Rod Genus’ we discussed?
1.Actinomyces 2.LactoBacillus 3.Rothia
What is the most common Gram + found in/on this tissue: Enamel? Cementum? Dentin?
1.Enamel=S. Mutans….. 2. Cementum=A. Israelii…..3. Dentin= L. Acidophilus
What are the 3 Gram - Cocci?
- Mor-ax-ella Cat-arr-hal-is 2.Neisseria 3. Veil-lo-nella Al-cal-esc-ens
What is the bacterium that is more common at periodontal disease sites and aggressive periodontits in juveniles? What is its Gram stain and shape?
Aggre-gati-bacter Actin-o-myc-et-em-comit-ans…Gram - Rod
What is the bacterium that is used as ‘scaffolding’ that other bacteria attach to? (gram stain and shape pleeezzz)
Fuso-bacterium Nucle-atum
4 Gram-negative rods often suggested as causative agents of periodontal disease! Go! ALSO….What is their nickname???(hint-color)
1.(he only gave us Genus) Bacter-oi-des 2.Tannerella For-syth-en-sis 3.Por-phy-ro-mon-as Gingivalis 4.Prevo-tella intermedia…Nickname:’Black-Pigenting-Bacteriodes’
Common in GI tract and found in GI infections. Also associated with periodontitis. Asaccharolytic….(shape and stain toooooo)
Bacteriodes (genus only)….Gram - rod
What are the three bacteria (gram stain and shape) that for the RED COMPLEX??? What is the RED COMPLEX associated with?
1.Tanner-ella Forsythen-sis 2.Pro-phy-ro-monas Gingivalis 3. Trep-on-ema Denticola……ALL are Gram - Rods…………..Red Complex is associated with AGRESSIVE perio infections.
What is the Gram - rod that is asaccharolytic and is not typically found in a healthy mouth?
Por-phy-rom-onas Gingivalis
What is the ONLY black-pigmenting bacteriode (and therefore Gram - rod) that is Saccharolytic?
Pre-vo-tella Intermedia
What is the only SPIROCHETE we talked about? What is it mainly associated with?
Trep-on-ema Denti-cola….Assoc. with Periodontitis
