In epidemiology, a disease vector is any living [ 1] agent that carries and transmits an infectious pathogen such as a parasite or microbe, to another living organism. [ 2][ 3] Agents regarded as vectors are mostly blood-sucking insects such as mosquitoes. The first major discovery of a disease vector came from Ronald Ross in 1897, who ...
tick bites, e.g. Ixodes scapularis. Balantidiasis. Balantidium coli. intestinal mucosa, may become invasive in some patients. stool (diarrhea=ciliated trophozoite; solid stool=large cyst with horseshoe shaped nucleus) ingestion of cyst, zoonotic infection acquired from pigs (feces) Blastocystosis. Blastocystis spp.
Vector control taking place in the Southern United States during the 1920s. Vector control is any method to limit or eradicate the mammals, birds, insects or other arthropods (here collectively called "vectors") which transmit disease pathogens. The most frequent type of vector control is mosquito control using a variety of strategies.
Typhus, also known as typhus fever, is a group of infectious diseases that include epidemic typhus, scrub typhus, and murine typhus. [1] Common symptoms include fever, headache, and a rash. [1] Typically these begin one to two weeks after exposure. [2] The diseases are caused by specific types of bacterial infection. [1]
Sandfly species transmit the disease leishmaniasis, by acting as vectors for protozoan Leishmania species, and tsetse flies transmit protozoan trypansomes (Trypanosoma brucei gambiense and Trypansoma brucei rhodesiense) which cause African Trypanosomiasis (sleeping sickness). Ticks and lice form another large group of invertebrate vectors.
List of fictional diseases, diseases found only in works of fiction. Airborne disease, a disease that spreads through the air. Contagious disease, a subset of infectious diseases. Cryptogenic disease, a disease whose cause is currently unknown. Disseminated disease, a disease that is spread throughout the body.
Lentiviral vectors in gene therapy is a method by which genes can be inserted, modified, or deleted in organisms using lentiviruses . Lentiviruses are a family of viruses that are responsible for diseases like AIDS, which infect by inserting DNA into their host cells' genome. [ 1] Many such viruses have been the basis of research using viruses ...
How vectors work to transfer genetic material. Gene therapy utilizes the delivery of DNA into cells, which can be accomplished by several methods, summarized below. The two major classes of methods are those that use recombinant viruses (sometimes called biological nanoparticles or viral vectors) and those that use naked DNA or DNA complexes (non-viral methods).
