Rats were the vector of the Bubonic Plague
Bubonic plague is usually transmitted by infected fleas. These fleas typically live on rodents, in particular rats.
xenopsylla cheopis is the scientific name of the flea that is the vector for Yersinia pestis, which is the bacteria that causes bubonic plague.
It was a bacterium that caused it, but rats and fleas between them were the vector which spread the disease.
The disease is transmitted from animals to humans.Plague infects wild rodents, especially rats, and is transmitted animal to animal and occasionally to humans by flea bites. The flea is the vector.
The Oriental rat flea (Xenopsylla cheopis) is a parasite of rodents, primarily of the genus Rattus, and is primary vector for bubonic plague and murine typhus.
Yes, they did get sick from the plague, in fact they were one of the animals in the chain of links which enabled us humans to catch the plague, (from the flea bites the rats were getting). In general this was bad for all the countries affected by the black death as it would leave the villages, towns, cities etc in a bad condition, which could cause even more disease in the long run.
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
Vectors play a crucial role in the transmission of diseases by transferring pathogens from one host to another. They can be insects like mosquitoes, ticks, or flies, as well as animals like rodents. Vectors act as carriers for diseases such as malaria, dengue fever, Lyme disease, and plague, among others.
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
Pneumonic Plague is the most serious form of plague. It should not be confused with Bubonic Plague, the "Black Death" of Medieval Europe. As it's name implies, it affects the lungs. It can be successfully treated if antibiotics are administered within the first 24 hours of symptoms appearing. Without treatment it is uniformly fatal in 36-48 hours. 98% of the cases reported each year occur in Africa.
