Gram + Branching
This bacteria is aerobic, Catalase + and Partially acid fast!
Anaerobic and spore forming
Clostridioides
Aerobic, Catalase +, Coagulase +, and encapsulated.
Staphylococcus auerus
Fast lactose fermenters, encapsulated.
E. Coli and Klebsiella
Aerobe, Coccobacillus, Catalase +, Reduced LPS content, found naturally in fresh water
causes the most severe form of atypical pneumonia
Legionella Pneumophila
This bacteria is an Obligate anaerobe, Catalase variable, Not Acid Fast!
Actinomyces
Aerobic and encapsulated. One of the most virulent food borne pathogens!
Listeria monocytogenes
Most common causative agent of pneumonia
Aerobic, Catalase -, Alpha hemolytic, and optochin sensitive.
Streptococcus pneumoniae
Slow Lactose fermenters
Citrobacter and Serratia
Aerobe, no peptidoglycan, stains with Giemsa instead of Gram Stain
Common cause of CA-pneumonia (atypical)
chlamydophila pneumoniae
Aerobic, encapsulated, and spore forming (HINT: could be in your fried rice)
Bacillus
Aerobic, Catalase -, Beta hemolysis, Bacitracin sensitive. Can cause Toxic Shock Syndrome
Streptococcus pyogenes
Does NOT ferment lactose and Oxidase +
Common infection in severe burn and cystic Fibrosis patients
Psuedomonas aeruginosa
Smallest self-replicating organism, no cell wall, cultured colonies look like fried eggs!
Causative agent of atypical pneumonia (walking pneumonia)
Mycoplasma pneumoniae
