Which of the following bacterial pathogens is classified under facultative anaerobic negative rods?
Show Hint
- Agrobacterium
- Xanthomonas
- Pectobacterium
- Ralstonia
The Correct Option is C
Solution and Explanation
Plant pathogenic bacteria are classified by Gram reaction, cell shape, and oxygen respiratory requirements.
Step 2: Detailed Explanation:
Pectobacterium (formerly Erwinia carotovora, family Pectobacteriaceae Enterobacterales) consists of Gram-negative, rod-shaped, peritrichously flagellated, facultative anaerobic bacteria causing soft rot in vegetables.
In contrast, Xanthomonas, Agrobacterium, and Ralstonia are strictly obligate aerobic Gram-negative rods.
Step 3: Final Answer:
Hence, Pectobacterium is classified as a facultative anaerobic Gram-negative rod.
