Leptospira Mayottensis
''Leptospira'' () is a genus of spirochaete bacteria, including a small number of pathogenic and saprophytic species. ''Leptospira'' was first observed in 1907 in kidney tissue slices of a leptospirosis victim who was described as having died of "yellow fever". Taxonomy ''Leptospira'', together with the genera ''Leptonema'' and ''Turneria'', is a member of the family Leptospiraceae. The genus ''Leptospira'' is divided into 20 species based on DNA hybridization studies.

Arthur James Boucot
Arthur James Boucot (May 26, 1924, Philadelphia, Pennsylvania, to 10 April 2017, Denver, Colorado) was an American paleontologist, biostratigrapher, and taphonomist who was an expert in Silurian and Devonian marine invertebrates, particularly brachiopods. Early life Boucot was born in Philadelphia, and raised in an academic family with early exposure to geology and paleontology. He began his studies at the University of Pennsylvania but dropped out in his freshman year to work at RCA. He was drafted into the United States Army during WWII, but enlisted in the United States Army Air Forces as a navigator with the Eighth Air Force on B-24 Bombers, and was awarded the Distinguished Flying Cross. Education and academic career Boucot obtained his geology degrees from Harvard University with a B.S. in 1948, an MS in 1949, and a PhD in 1953. Although he began his geological studies focused on mineralogy and petrography, his interest in paleontology was sparked at Harvard by assistant ...

Micrometer (unit)
The micrometre (English in the Commonwealth of Nations, Commonwealth English as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American English), also commonly known by the non-SI term micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI Unit, SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cell (biology), cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of str ...

Leptospira Wolffii
''Leptospira wolffii'' is a gram negative aerobic bacterium in the spirochaete phylum. The species named after Dutch bacteriologist Jan Willem Wolff. Description As with other species in the phylum, ''L. wolffii'' has a spiral shape and uses its endoflagella for movement. Within the genus of ''Leptospira'', ''L. wolffii'' falls within the intermediate or opportunistic pathogen clade. The microbe is 10-13 μM long and 0.2 μM wide, making difficult to see unless using dark-field microscopy, so genetic analysis is a common means of identification. Pathogeny ''Leptospira wolffii'' was first identified in Thailand from a patient's urine sample, who had contracted leptospirosis Leptospirosis is a blood infection caused by the bacterium ''Leptospira'' that can infect humans, dogs, rodents and many other wild and domesticated animals.

Leptospira Alstonii
''Leptospira alstonii'' is a gram negative, mobile, spirochete. It is flexible, helical, and motile by means of two periplasmic flagella (axial fibrils). It is obligately aerobic and oxidase positive. It was named after J. M. Alston, a British microbiologist who made significant contributions to the study of ''Leptospirosis''. It is one of nine human or animal pathogenic species of ''Leptospira''. It was originally isolated from material submitted to the Veterinary Diagnostic Laboratory at Iowa State University during an outbreak of swine abortion in 1983. It has been isolated and stored in liquid nitrogen or Ellinghausen-McCullough-Johnson-Harris medium.Alexander, A. D., E. F. Lessel, L. B. Evans, E. Franck, and S. S. Green. 1972.
