Epidemiological surveillance relies on precisely categorizing pathogen types and their transmission vectors. Which of the following statements correctly describe the etiology and transmission dynamics of human infectious diseases?
- Bubonic plague is a bacterial infection caused by Yersinia pestis, primarily transmitted to humans through the bites of infected oriental rat fleas (Xenopsylla cheopis).Cevap
- BBrucellosis is a protozoan disease transmitted exclusively through the bites of infected Anopheles mosquitoes.
- Epidemic typhus is caused by the bacterium Rickettsia prowazekii and is vector-transmitted to humans by the human body louse (Pediculus humanus humanus).Cevap
- DMalaria is a bacterial infection of the human lymphatic system transmitted through consumption of contaminated drinking water.
Cevap
The correct statements are the ones describing Bubonic plague as a bacterial infection transmitted by rat fleas, and Epidemic typhus as a bacterial infection caused by Rickettsia prowazekii transmitted by the human body louse.
The statements describing Bubonic plague and Epidemic typhus are scientifically accurate. Bubonic plague is caused by the Gram-negative bacterium Yersinia pestis and spread by the rat flea Xenopsylla cheopis. Epidemic typhus is caused by the obligate intracellular bacterium Rickettsia prowazekii, transmitted by the human body louse Pediculus humanus humanus.
