biological vector

Biological vectors can include bacteria or more commonly algae.

The biological vector of the virus is the Culicoides (midges) species.

The waters off North Carolina host numerous fish, a potential biological vector for transport of waste materials.

Biological vectors are usually, though not exclusively, arthropods, such as mosquitoes, ticks, fleas and lice.

Use of a biological vector as a means to split water, and therefore produce hydrogen gas, would allow for the only energy input to be solar radiation.

Oxytrema silicula stream snails are biological vectors for a larval stage of N. salmincola.

The mosquito serves as a biological vector - it is required for the developmental cycle of the parasite (see Life Cycle).

He also conducted important research involving the African tsetse fly (Glossina palpalis) as a biological vector for trypanosomiasis.

In contrast, biological vectors harbor pathogens within their bodies and deliver pathogens to new hosts in an active manner, usually a bite.

Species in the genus Chrysops are biological vectors of Loa loa, transmitting this parasitic filarial worm between humans.

Biological vectors are often responsible for serious blood-borne diseases, such as malaria, viral encephalitis, Chagas disease, Lyme disease and African sleeping sickness.

They live by feeding on the blood of vertebrate animals and are the primary African biological vectors of trypanosomes, which cause human sleeping sickness and animal trypanosomiasis, also known as nagana.

Most commonly known biological vectors are arthropods but many domestic animals too are important vectors or asymptomatic carriers of parasites and pathogens that attack humans or other animals.

In the following decade, the US accumulated significant data on personnel protection, decontamination, and immunization; and, in the offensive program, on the potential for mosquitoes to be used as biological vectors.

Tsetse are biological vectors of trypanosomes meaning that tsetse, in the process of feeding, acquire and then transmit small, single-celled organisms called trypanosomes from infected vertebrate hosts to uninfected animals.

Acting as both biological vectors and definitive hosts, humans have spread Tunga penetrans from its isolated existence in the West Indies to all of Latin America and most of Africa via sea travel.

More than once when Earth was still the All for all of Kirk's kind, the species had arrived at the capacity to destroy that All: the early atomic crisis, neutron bombs and doomsday weapons, biological vectors, chemical planet killers.

It is a positive-sense ssRNA virus and the type species of the genus Panicovirus, readily spread by humans through tools such as lawn mower blades, but not known to be spread via biological vectors such as insects.

The California study notes that "feral cats, rodents, skunks, opossums, wild birds, and other wildlife" were seen near the free-range hens' feeding areas, and that rodents "were considered to be the biological vectors and amplifiers" of salmonella on the egg farm in the study.

Dr. Jeffrey S. Chamberlain, an assistant professor of human genetics at the University of Michigan at Ann Arbor who led the research team, said the next step would be to engineer a virus or other biological vector that contained the corrected dystrophin gene developed during the study.
