Bacterial Motility, Growth Curve, and Sterilisation Notes

Vocabulary flashcards covering bacterial motility types, growth curve phases, related clinical findings, and dry heat sterilisation parameters based on lecture notes.

H Ag

The flagella antigen associated with bacterial motility.

Listeria Motility

Exhibits differential motility described as tumbling, which is positive ($+$) at 22\text{--}25^\frac{1}{2}^\text{C} (or $22\text{--}25^\text{o}\text{C}$) / $22\text{--}25^\text{C}$ and negative ($-$) at $37^\text{C}$.

Vibrio Cholera Motility

Exhibits darting motility.

Swarming Motility (PVCS)

Motility pattern characteristic of Proteus, V. parahemolyticus, C. tetani, and Serratia.

Treponema Pallidum Motility

Exhibits corkscrew motility.

Trichomonas Motility

Exhibits twitching or jerking motility.

Giardia Lamblia Motility

Exhibits falling leaf motility.

Dienes Phenomenon

Phenomenon observed between different Proteus strains, producing a line of demarcation.

Proteus Kidney Stone

Staghorn calculus consisting of triple PO.

Lag Phase

The stage of the bacterial growth curve where bacteria reach maximum size.

Log Phase

The stage of active cell division in the bacterial growth curve where bacteria are most susceptible to antibiotics.

Stationary Phase (STAB)

The stage of the bacterial growth curve characterized by Sporulation, Exo Toxin production, Antibiotic production, and Bacteriocin production.

Hot Air Oven Parameters

A physical dry heat sterilisation method operating at $160^\text{C} \times 2\text{HRS}$, used for glass, cotton swabs, oil, greasy materials, liquids, and dusty powders.
