AST and ALT are considered to be two of the most important tests to detect liver injury, although ALT is more specific to the liver than is AST. Sometimes AST is compared directly to ALT and an AST/ALT ratio is calculated.
Borrelia Burgdorferi. Lyme disease is caused by a number of different strains and species of Borrelia bacteria, generally Borrelia burgdorferi in the United States and Borrelia afzelii and Borrelia garinii in Europe. The Borrelia burgdorferi bacteria are named after scientist Willy Burgdorfer, who first identified the strain in the early 1980s.
Furthermore, some bacteria have linear chromosomes. Borrelia 3 have linear chromosomes and most strains contain both linear and circular plasmids; most of the bacteria in the genus Streptomyces 4 have linear chromosomes and plasmids and some have circular plasmids as well. For example, linear DNA was precipitated in the most commonly used procedures for purifying bacterial plasmids, and the procedures for purifying chromosomal DNA relied upon the differential binding of ethidium bromide to sheared DNA fragments compared to circular DNA.
