Peliosis Hepatis
Peliosis hepatis is an uncommon vascular condition characterised by multiple, randomly distributed, blood-filled cavities throughout the liver. The size of the cavities usually ranges between a few millimetres and 3 cm in diameter. Chapter 80 In the past, it was a mere histological curiosity occasionally found at autopsies, but has been increasingly recognised with wide-ranging conditions from AIDS to the use of anabolic steroids. It also occasionally affects spleen, lymph nodes, lungs, kidneys, adrenal glands, bone marrow, and other parts of gastrointestinal tract. Peliosis hepatis is often erroneously written "peliosis hepati''ti''s", despite its not being one of the hepatitides. The correct term arises from the Greek ''pelios'', i.e. discoloured by extravasated blood, livid, and the Latinized genitive case (hepatis) of the Greek ''hepar'', liver. Signs and symptoms Often, peliosis hepatis causes no symptoms (asymptomatic). In other cases, it may be identified after blo ...

Bartonella
''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. '' Bartonella henselae'' is the organism responsible for cat scratch disease. History ''Bartonella'' species have been infecting humans for thousands of years, as demonstrated by '' Bartonella quintana'' DNA in a 4000-year-old tooth. The genus is named for Alberto Leonardo Barton Thompson (1871–October 26, 1950), a Peruvian scientist. Infection cycle Though some studies have found "no definitive evidence of transmission by a tick to a vertebrate host," ''Bartonella'' species are well-known to be transmissible to both animals and humans through va ...

Bacterial Diseases
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 many are 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 considered part of the gut flora, with a few hundred species present in each individual human's 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
