Which microbe will cause the plague

Which microbe will cause the plague

• A. Yersinia pestis
• B. Vibrio cholerae
• C. Bacillus anthracis
• D. Streptococcus pyogenes

Answer: (A)

Plague is caused by Yersinia pestis, a Gram-negative rod that is typically transmitted to humans by fleas feeding on infected rodents. This organism can cause bubonic plague, marked by swollen lymph nodes, and can progress to septicemic or pneumonic plague, with the pneumonic form capable of spreading between people via respiratory droplets in advanced disease. The other microbes listed are associated with different diseases: Vibrio cholerae causes cholera, Bacillus anthracis causes anthrax, and Streptococcus pyogenes causes strep infections and related conditions. So, the microbe linked to plague is Yersinia pestis. In embalming practice, this highlights the importance of standard precautions and appropriate containment when handling remains with potential plague risk.
