Solution and Explanation
Bubonic plague is an infectious disease that is often associated with the presence of swollen lymph nodes, known as buboes. The primary vector responsible for transmitting the bacteria causing the bubonic plague is the flea Xenopsylla cheopis, commonly known as the rat flea. This flea typically infests rodents, particularly rats, which are reservoirs for the bacterium Yersinia pestis, the causative agent of the disease. When an infected rat flea bites a human, the bacterium can be transmitted, leading to the development of buboes. Therefore, in the context of an outbreak of buboes in a community, the most likely vector is Xenopsylla cheopis, the rat flea.
| Vector | Description |
|---|---|
| Xenopsylla cheopis | Rat Flea - Primary vector for bubonic plague |
| Tse tse fly | Vector for African sleeping sickness |
| Human flea | Not a common vector for bubonic plague |
| Sand fly | Vector for leishmaniasis |
In conclusion, the vector associated with an outbreak of buboes in a community is the Xenopsylla cheopis, or rat flea.
