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 ...
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.
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.
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]
The most commonly used gammaretroviral vector is a modified Moloney murine leukemia virus (MMLV), able to transduce various mammalian cell types. MMLV vectors have been associated with some cases of carcinogenesis. [26] Gammaretroviral vectors have been successfully applied to ex vivo hematopoietic stem cell to treat multiple genetic diseases.

Adeno-associated virus. Adeno-associated virus serotype 2 structure from 1LP3. One fivefold axis shown center. Adeno-associated viruses ( AAV) are small viruses that infect humans and some other primate species. They belong to the genus Dependoparvovirus, which in turn belongs to the family Parvoviridae.
While pythons are not venomous, they do carry a host of potential health issues for humans. Pythons are disease vectors for multiple illnesses, including Salmonella, Chlamydia, Leptospirosis, Aeromoniasis, Campylobacteriosis, and Zygomycosis. These diseases may be transmitted to humans through excreted waste, open wounds, and contaminated water.
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).
