Gram (-)
Bacilli polar flagellae motile non-spore former slow growth |
|
|
Characteristics of S. epidermis

Catalase (+)
Coagulase (-) Protein A (-) White colonies Colonize skin |
|
|
Characteristics of Staphylococcus Aureus

Gram (+) bacillus, non-spore former, intracellular invasion, facultative anaerobe
|
|
|
General characteristics of E. coli, including serotyping
|

H Ag: Flagellar protein O Ag: LPS polysaccharide K Ag: Capsular polysaccharide |
|
|
Characteristics of Salmonella
|
Gram (-), non-lactose fermenter, facultative anaerobe
|
|
|
EPEC
|
Enteropathogenic E. coli
- Similar to EHEC - no Shiga-like toxin - diarrhea with mucous, but little or no blood - malaise, vomiting, fever - childhood fever in developing countries |
|
|
Characteristics of Helicobacter pylori
|
- gram (-)
- helical - slow growth - microaerophilic |
|
|
General properties of C. tetani?
|
Thin gram + rod
Strict anaerobe Spore former Motile Non-invasive |
|
|
General properties of Legionella pneumophila
|
Gram - bacillus
Parasitizes protazoa in the environment |
|
|
General properties of chlamydiae, rickettsiae, coxiella, erlichia, and anaplasma
|
Degenerate
Highly specialized Gram-negative Only grow in eukaryotic cells Have lost many of their biosynthetic pathways Have small genomes |
|
|
General properties of spirochetes.
|
Corkscrew shapes
Thin - need DARKFIELD MIRCOSCOPY to see them Possess inner and outer membranes like gram negatives, but they are not conventional gram negatives. Don't gram stain well Have ENDOFLAGELLA and are highly motile. Due to their motility, they cause systemic infection. Difficult/impossible to grow in vitro. |
|
|
Basic characteristics of Mycobacterium tuberculosis
|
Aerobic, slow-growing rod
Has a waxy coat so doesn't gram stain Can use an acid-fast stain instead. |
|
|
Coxiella burnetii: characteristics
|
Highly infectious spore like elementary body
Seen in agricultural workers working with animals giving birth. Reaches very high concentrations in placenta. Has been used for nonlethal bioweapons Extremely infectious |
|
|
Basic characteristics of brucella
|
Pleomorphic gram - rod
Urease-producing Facultative intracellular |
|
|
General properties of V. cholera
|
Gram negative
Comma-shaped Facultatice anaerobe Non-spore former Non-invasive Highly motile Able to replicate at alkaline pH Classic example of disease with all important symptoms due to action of a single toxin. |
|
|
General properties of Corynebacterium diptheria
|
Gram + rod
Non-spore forming Facultative anaerobe Non-motile Non-invasive This was the first bacterial disease known to be caused entirely by a toxin. |
