In biology, a tropism is a phenomenon indicating the growth or turning movement of an organism, usually a plant, in response to an environmental stimulus. In tropisms, this response is dependent on the direction of the stimulus. Tropisms are usually named for the stimulus involved; for example, a phototropism is a movement to the light source, and an anemotropism is the response and adaptation of plants to the wind.
Scrub typhus or bush typhus is a form of typhus caused by the intracellular parasite Orientia tsutsugamushi, a Gram-negative α-proteobacterium of family Rickettsiaceae first isolated and identified in 1930 in Japan.
Bartonella is a genus of Gram-negative bacteria. It is the only genus in the family Bartonellaceae. Facultative intracellular parasites, Bartonella species can infect healthy people, but are considered especially important as opportunistic pathogens. Bartonella species are transmitted by vectors such as fleas, sand flies, and mosquitoes. At least eight Bartonella species or subspecies are known to infect humans.
Viral pathogenesis is the study of the process and mechanisms by which viruses cause diseases in their target hosts, often at the cellular or molecular level. It is a specialized field of study in virology.
Schistosoma intercalatum is a parasitic worm found in parts of western and central Africa. There are two strains: the Lower Guinea strain and the Zaire strain. S. intercalatum is one of the major agents of the rectal form of schistosomiasis, also called bilharzia. It is a trematode, and being part of the genus Schistosoma, it is commonly referred to as a blood-fluke since the adult resides in blood vessels.
Alkhurma virus (ALKV) is a zoonotic virus of the Flaviviridae virus family. ALKV causes Alkhurma hemorrhagic fever (AHF), or alternatively termed as Alkhurma hemorrhagic fever virus, and is mainly based in Saudi Arabia.
Viral vectors are modified viruses designed to deliver genetic material into cells. This process can be performed inside an organism or in cell culture. Viral vectors have widespread applications in basic research, agriculture, and medicine.
Betaherpesvirinae is a subfamily of viruses in the order Herpesvirales and in the family Herpesviridae. Mammals serve as natural hosts. There are 26 species in this subfamily, divided among 5 genera. Diseases associated with this subfamily include: human cytomegalovirus (HHV-5): congenital CMV infection; HHV-6: 'sixth disease' ; HHV-7: symptoms analogous to the 'sixth disease'.
Ecotropism or ecotropic refers to the philosophy that for human culture to be healthy, it must exist as in an ecological niche and thereby relate appropriately with all the fields of forces of nature, organic and inorganic. The following form of the term has been used since 1990 in the publication of "Toward an Ecotropic Poetry", by John Campion and John Herndon.
Tissue tropism is the range of cells and tissues of a host that support growth of a particular pathogen, such as a virus, bacterium or parasite.
Host tropism is the infection specificity of certain pathogens to particular hosts and host tissues. This explains why most pathogens are only capable of infecting a limited range of host organisms.
The 15th César Awards ceremony, presented by the Académie des Arts et Techniques du Cinéma, honoured the best French films of 1989 and took place on 4 March 1990 at the Théâtre des Champs-Élysées in Paris. The ceremony was chaired by Kirk Douglas and hosted by Ève Ruggiéri. Too Beautiful for You won the award for Best Film.
Tropical rock is a genre of popular music that incorporates elements and influences of rock, reggae, country, folk, calypso, zydeco, and pop music, with themes and musical compositions inspired by an island style.
Amblyomma cajennense or Cayenne tick is a species of tick found in a range from the southern part of the United States to northern Argentina, through Central America and some of the Caribbean. As a consequence, the species has adapted to a wide range of environmental conditions. There are also major geographic barriers such as large rivers and the Andes mountain range.
Paragonimus kellicotti, the North American lung fluke, is a species of parasitic trematode in the genus Paragonimus. This species of Paragonimus has an intricate lifecycle, and although its name may suggest that it is only a health concern in North America, it is also prominent in Southeast Asia and China.
Thailand virus (THAIV) is a single-stranded, enveloped, negative-sense RNA orthohantavirus.
Otokonoko is a Japanese term for men who have a culturally feminine gender expression. This includes amongst others males with feminine appearances, or those cross-dressing. "Otokonoko" is a play on the word 男の子, which is also pronounced otokonoko; in the slang term, the kanji for "child" (子) is substituted with "daughter"/"girl" (娘).
Carmotetraviridae is a family of positive-strand RNA viruses. There is only one genus in this family, Alphacarmotetravirus, which has one species: Providence virus. Lepidopteran insects serve as natural hosts.
Tibrovirus is a poorly characterized genus of viruses in the family Rhabdoviridae, order Mononegavirales. There are 8 members of the genus. Tibroviruses have been isolated from biting midges, cattle, and humans. None of the tibroviruses, except for Bas-Congo virus, have been associated with any diseases.
Endothelial cell tropism or endotheliotropism is a type of tissue tropism or host tropism that characterizes an pathogen's ability to recognize and infect an endothelial cell. Pathogens, such as viruses, can target a specific tissue type or multiple tissue types. Like other cells, the endothelial cell possesses several features that supports a productive viral infection a cell including, cell surface receptors, immune responses, and other virulence factors. Endothelial cells are found in various tissue types such as in the capillaries, veins, and arteries in the human body. As endothelial cells line these blood vessels and critical networks that extend access to various human organ systems, the virus entry into these cells can be detrimental to virus spread across the host system and affect clinical course of disease. Understanding the mechanisms of how viruses attach, enter, and control endothelial functions and host responses inform infectious disease understanding and medical countermeasures.
