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 ...
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]
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.
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. [27]
Wild-type AAV has attracted considerable interest from gene therapy researchers due to a number of features. Chief amongst these was the virus's apparent lack of pathogenicity. It can also infect non-dividing cells and has the ability to stably integrate into the host cell genome at a specific site (designated AAVS1) in the human chromosome 19 .
Mathematical models can project how infectious diseases progress to show the likely outcome of an epidemic (including in plants) and help inform public health and plant health interventions. Models use basic assumptions or collected statistics along with mathematics to find parameters for various infectious diseases and use those parameters to ...
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 ...
