BACTERIAL TAXONOMY Henson B. Turalde, RPh, LPT  Presence and properties of cell wall TAXONOMY Oxygen utilization includes classification, identification, and Shape and arrangement of cells nomenclature of microorganisms Spore formation Others I. PRESENCE AND PROPERTIES OF CELL WALL A. With cell wall 1. Gram(+) 2. Gram(-) 3. Acid-fast B. Without cell wall  Gram Staining: General Rules All cocci are Gram- Bacteria All bacilli that cannot are Gram-negative, be seen on Gram stainingEXCEPT positive, EXCEPT Bacillus Thick mycolic acid layer Thin or absent cell wall Actinomyces Neisseria Mycoplasma Veillonella Cryptosporidium, Cyclospora Nocardia Chlamydia Moraxella (protozoan) Streptomyces Legionella micdadei Corynebacterium, Clostridium Legionella pneumophila NVM Isospora (protozoan) Erysipelothrix Rickettsia Nocardia Listeria, (weakly acid fast) Lactobacillus Treponema Mycobacterium (Gram- Mycobacterium variable) Propionibacterium MCLRT CLINM BANSCEL MP II. OXYGEN UTILIZATION A. Obligate aerobe B. Facultative anaerobe C. Obligate anaerobe D. Aerotolerant anaerobe E. Microaerophile  OBLIGATE AEROBES: OBLIGATE ANAEROBES: Obligate grow only require insurvival O2 for the absence of O Pseudomonas aerobes 2 Nocardia Actinomyces REQUIREMENT Bacillus Bacteroides Obligate Mycobacterium Clostridium anaerobes OXYGEN Corynebacterium Eubacterium MICROAEROPHILES: Fusobacterium require ↓ O2, however ↑ AEROTOLERANT: Prevotella PNBMC Microaerophiles O O2 and → toxic 2 concentration tolerates Campylobacter continues ABCEFP growth in its Helicobacter Aerotolerant presence FACULTATIVE LactobacillusANAEROBES: Propionibacterium could thrive with or Facultative without O2 anaerobes LP THE REST!!! III. SHAPE AND ARRANGEMENT OF CELLS A. Cocci – spherical 1. diplococci – pairs 2. staphylococci – clusters 3. streptococci – chains B. Bacilli – rod-shaped 1. diplobacilli – pairs 2. staphylobacilli – clusters 3. streptobacilli – chains C. Vibrio – curved rod D. Spirochete – flexible helical E. Spirilla – rigid helical IV. SPORE FORMATION A. Spore-forming B. Non-spore forming Gram Positive Bacilli Gram Staining: General Rules All cocci are Gram- All bacilli are Gram-negative, EXCEPT positive, EXCEPT Bacillus Spore-formers Actinomyces Neisseria Veillonella Nocardia Moraxella Streptomyces Non-spore- Corynebacterium, Clostridium NVM formers Erysipelothrix Listeria, Lactobacillus Mycobacterium Propionibacterium BANSCEL MP Gram Positive Bacilli Sporeformers All bacilli are Gram-negative, EXCEPT Bacillus Actinomyces Non- Nocardia Streptomyces sporeformers Corynebacterium, Clostridium Erysipelothrix Listeria, Lactobacillus Mycobacterium Propionibacterium BANSCEL MP V.
