		In biology, a host is an organism that harbors a parasite, mutual partner, or commensal partner, typically providing nourishment and shelter.
		A host may also be a group, such as an army or a large number of people under a single cause or banner.
		In Roman Catholicism, the host is the transubstantiated bread in the Eucharist.

	Host - Wikipedia, the free encyclopedia
		In television or radio, the host of a show is the person who presents it - for example Jay Leno is the current host of The Tonight Show.
		In biology, a host organism harbors a parasite, mutual partner, or commensal partner, typically providing nourishment and shelter.
		In computing, host is any machine connected to a computer network, a node that has a hostname.

	NIH Guide: ONTOGENY OF PERINATAL HOST DEFENSES
		The Developmental Biology, Genetics and Teratology Branch, and Pregnancy and Perinatology Branch of the CRMC are particularly interested in supporting basic studies on the ontogeny of perinatal host defenses and developmental and reproductive immunobiology.
		Host defense mechanisms that protect the fetus, neonate and infant are varied, complex and interactive.
		Non-specific, natural or innate host defense mechanisms include physical and chemical barriers; humoral components (e.g., serum opsonins, complement factors, fibronectin, c-reactive proteins, and lactoferrin); natural killer (NK) cells; phagocytic cells (e.g., neutrophils, monocytes, macrophages); as well as soluble plasma and tissue proteins that amplify the action of phagocytes to become natural immune effector cells.

	Tick Biology
		Hard ticks seek hosts by an interesting behavior called "questing." Questing ticks crawl up the stems of grass or perch on the edges of leaves on the ground in a typical posture with the front legs extended, especially in response to a host passing by.
		This type of tick remains on one host during the larval and nymphal stages, until they become adults, and females drop off the host after feeding to lay their batch of eggs.
		Some soft ticks seek hosts by questing on low-lying vegetation, but the vast majority are nest parasites, residing in sheltered environments such as burrows, caves, or nests.

		A parasite is an organism that lives in or on the living tissue of a host organism at the expense of that host.
		Cells in culture, stained for keratin (red) and DNA (green) The cell is the structural and functional unit of all living organisms, sometimes called the building blocks of life.
		In parasitology, an intermediate host is an organism that is infected with a parasite that will not reproduce sexually within it, while a definitive host is one in which the parasite reproduces.

	Immunology and Infection Unit: Research on cell biology and host-pathogen interactions
		Understanding host-pathogen interactions in the leishmaniases requires both knowledge of those parasite factors that are important in virulence and in-depth investigation of host innate and adaptive immune responses to infection.
		It is thought these may affect the host response to the bacterial infection differently than single cells, and we are in the process of developing projects to address this.
		We are therefore studying the interactions between the intestinal bacterium Helicobacter hepaticus and cells of the innate immune system, such as dendritic cells that are among the first cells of our immune system to come in contact with the organism and that are involved in the initial priming of CD4+ T cells.

		If you've tried some other "bargain" hosts, you know that these times can be orders of magnitude larger, which is just painful when your site has a problem.
		I could say you like single-plan hosts, as they came in at positions one, four, and six, but there were still seven in there that are multi-plan.
		You like hosts with generous storage and transfer allowances, but that's a bit of a no-brainer.

		Viruses multiply, or replicate using their own genetic material and the host cell's machinery to create more viruses.
		Viruses cannot reproduce on their own, and must infect a host cell in order to create more viruses.
		Penetration - the virus is engulfed by the cell, or some viruses have surface proteins that bind to receptors on the host cell, causes the host cell to either fuse with the virus or absorb the virus.

	Theriot Lab Research
		Both grow directly in the cytoplasm of infected host cells, and move rapidly throughout the infected cell using a remarkable form of actin-based motility.
		Within a few hours after infection, host cell actin filaments initially form a dense cloud around the intracytoplasmic bacteria, and then rearrange to form a polarized "comet tail," which is associated with all moving bacteria.
		We are currently attempting to identify host cell factors that interact with the bacterial proteins so that we can reconstitute motility in a defined biochemical system.

		The simian malaria parasites in their macaque monkey hosts make excellent dependable models for the biology of the human malarias in human hosts.
		However, only the New world primates can be infected with the human parasites and as such are the only available animal models to study vaccine efficacy or drug susceptibility of human malaria parasites.
		These nonhuman primate hosts of human malarias and of the simian malaria parasites also offer faithful models to investigate mechanisms and treatments for severe pathology associated with malaria infections such as anemia, cerebral malaria and malaria in pregnancy.

		Ninety percent of the cells in the human body are bacteria, and humans may be host to many thousands of different species of bacteria.
