Ixodes Pararicinus

picture info	Ixodes Pararicinus ''Ixodes'' is a genus of hard-bodied ticks (family Ixodidae). It includes important disease Vector (epidemiology), vectors of animals and humans (tick-borne disease), and some species (notably ''Ixodes holocyclus'') inject toxins that can cause paralysis. Some ticks in this genus may transmit the pathogenic bacterium ''Borrelia burgdorferi'' responsible for causing Lyme disease. Additional organisms that may be transmitted by ''Ixodes'' are parasites from the genus ''Babesia'', which cause babesiosis, and bacteria from the related genus ''Anaplasma'', which cause anaplasmosis. Species These species are recognised within the genus ''Ixodes'': ''Ixodes abrocomae'' Lahille, 1917 ''Ixodes acer'' Apanaskevich & Schenk, 2020 ''Ixodes acuminatus'' Neumann, 1901 ''Ixodes acutitarsus'' (Karsch, 1880) ''Ixodes affinis'' Neumann, 1899 ''Ixodes albignaci'' Uilenberg & Hoogstraal, 1969 ''Ixodes alluaudi'' Neumann, 1913 ''Ixodes amarali'' Fonseca, 1935 ''Ixodes amersoni'' Kohls, ...

	Ixodes Ricinus ''Ixodes ricinus'', the castor bean tick, is a chiefly European species of hard-bodied tick. It may reach a length of when engorged with a blood meal, and can transmit both bacterial and viral pathogens such as the causative agents of Lyme disease and tick-borne encephalitis. Description In common with other species of '' Ixodes'', ''I. ricinus'' has no eyes and is not ornate; it has no festoons (wrinkles along the posterior margin). The palpi are longer than they are wide, and an anal groove is above the anus. It has a hard dorsal shield which covers the entire opisthosoma (abdomen), but only part of it in females and nymphs. ''I. ricinus'' is the largest of the three common species of ''Ixodes'' in the British Isles (the other two being '' I. canisuga'', the British dog tick, and '' I. trianguliceps'', the vole tick). Adult males are long, and unfed nymphs are long; females are long before feeding and long when engorged. Distribution ''Ixodes ...

picture info	Pathogenic Bacterium Pathogenic bacteria are bacteria that can cause disease. This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and are often beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. By contrast, several thousand species are part of the gut flora present in the digestive tract. The body is continually exposed to many species of bacteria, including beneficial commensals, which grow on the skin and mucous membranes, and saprophytes, which grow mainly in the soil and in decaying matter. The blood and tissue fluids contain nutrients sufficient to sustain the growth of many bacteria. The body has defence mechanisms that enable it to resist microbial invasion of its tissues and give it a natural immunity or innate resistance against many microorganisms. Pathogenic bacteria are specially adapted and endowed with mechanisms for overcoming the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
