✏️ Part B
Fill in the Blanks! 🖊️
Type your answer in each blank, then click Check.
1
Proteus mirabilis demonstrates motility, spreading in concentric rings on non-inhibitory agar. 🌊
✅ Answer: swarming
2
Treponema pallidum corkscrew motility is observed under microscopy — it cannot be grown in standard culture. 🔍
✅ Answer: darkfield
3
motility in Listeria monocytogenes is the classic “end-over-end” movement. 🤸
✅ Answer: tumbling
4
Listeria monocytogenes shows this motility at °C, NOT at body temperature. 🌡️
✅ Answer: 25°C (room temperature)
5
spp. show flagella-independent gliding motility on agar surfaces. 🛸
✅ Answer: Capnocytophaga
6
Both Campylobacter and share “shooting star” motility due to their single . ⭐
✅ Answers: Vibrio cholerae · polar flagellum
🟢 Part C
True or False? 🤔
Tap TRUE or FALSE — instant feedback after each answer.
1
Treponema pallidum can be cultured in standard laboratory media and its corkscrew motility is assessed using a hanging drop preparation. 🧫
❌ FALSE. T. pallidum cannot be cultured in vitro. Its corkscrew movement is observed under darkfield microscopy, not hanging drop.
2
Listeria monocytogenes shows tumbling motility at 37°C because its peritrichous flagella are fully active at body temperature. 🌡️
❌ FALSE. Tumbling motility is expressed at 25°C (room temperature), not 37°C. Classic MCQ trap! 🌡️
3
Both Campylobacter and Vibrio cholerae can be described as having “shooting star” motility in different references. 🌠
✅ TRUE. Both share the “shooting star” descriptor. Lean toward Campylobacter for “darting” and Vibrio cholerae for “rapid darting/shooting star.”
4
Capnocytophaga uses flagella to produce its gliding motility on agar surfaces. 🛸
❌ FALSE. Capnocytophaga gliding is flagella-independent — surface-dependent mechanism.
5
The swarming of Proteus mirabilis on agar can be suppressed using SIM medium. 🌊
✅ TRUE. SIM (semi-solid) medium suppresses swarming and allows motility assessment as diffuse growth. Also tests H₂S and indole simultaneously. 🧫
🧠 Part D
From Memory! 🌟
No word box this time. Type the organism for each motility type from memory.
🌀
Corkscrew motility
✅ Treponema pallidum
⚠️ Darkfield only; not culturable in vitro
💨
Darting motility
✅ Campylobacter spp.
⚠️ Also “shooting star”; single polar flagellum
🛸
Gliding motility
✅ Capnocytophaga spp.
⚠️ Flagella-independent surface motility
🌊
Swarming motility
✅ Proteus mirabilis
⚠️ Concentric rings; peritrichous flagella
🤸
Tumbling motility
✅ Listeria monocytogenes
⚠️ At 25°C only — NOT at 37°C!
🌠
Rapid Darting / Shooting Star
✅ Vibrio cholerae
⚠️ Overlaps with Campylobacter descriptor
