Question

2. Which of the following Enterobacteriaceae members is transmitted to humans through fleas? Morganella morganii b) Salmonella typhimurium (Shigella dysenteriae d) Klebsiella pneumoniae Yersinia pestis

Answer 1

Correct answer is, e) Yersinia pestis

Yersinia pestis, the etiological agent of the zoonosis plague, is transmitted from diseased rodents to humans by the bite of infected fleas.

Other options are wrong because,

Morganella morganii is a gram-negative rod commonly found in the environment and in the intestinal tracts of humans, mammals, and reptiles as normal flora.

Salmonella Transmission is usually person-to-person or animal-to-person via the faecal–oral route, through ingestion of the organisms via contaminated or improperly cooked foods.

Shigella is transmitted through contaminated food and water.

Klebsiella spreads from person to person by contact.
