Plant virus transmission strategies in insect vectors. Plant viruses need to be transmitted by a vector, most often insects such as leafhoppers. One class of viruses, the Rhabdoviridae, has been proposed to actually be insect viruses that have evolved to replicate in plants. The chosen insect vector of a plant virus will often be the ...
For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus. Although invertebrate-transmitted diseases pose a particular threat on the continents of Africa, Asia and South America, there is one way of controlling invertebrate-borne diseases, which is by controlling the invertebrate vector.
Bunyaviruses belong to the fifth group of the Baltimore classification system, which includes viruses with a negative-sense, single-stranded RNA genome. They have an enveloped, spherical virion. Though generally found in arthropods or rodents, certain viruses in this order occasionally infect humans. Some of them also infect plants. [6]
In 2015 two novel rhabdoviruses, Ekpoma virus 1 and Ekpoma virus 2, were discovered in samples of blood from two healthy women in southwestern Nigeria. Ekpoma virus 1 and Ekpoma virus 2 appear to replicate well in humans (viral load ranged from ~45,000 - ~4.5 million RNA copies/mL plasma) but did not cause any observable symptoms of disease. [24]
Tibovirus (tick-borne virus) is sometimes used to more specifically describe viruses transmitted by ticks, a superorder within the arthropods. [2] Arboviruses can affect both animals (including humans) and plants. [3] In humans, symptoms of arbovirus infection generally occur 3–15 days after exposure to the virus and last three or four days.

This virus shows different symptoms in Europe; for example, the infected plants usually show dark brown necrotic arcs that discolor the tuber's flesh (these symptoms are very similar to those caused by alfalfa mosaic virus). [5] Plants showing no symptoms of PMTV tend to produce larger quantities of infected tubers if they are derived from ...
