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.
In 1982, the etiologic agent of Lyme disease was discovered by Willy Burgdorfer, who isolated spirochetes belonging to the genus Borrelia from the mid-guts of Ixodes ticks. He showed that these spirochetes reacted with immune serum from patients that had been diagnosed with Lyme disease. Lyme disease has been found in all 50 states. Lyme disease is a systemic infection that results from the bite of a tick and the bacteria, borrelia burgdorfi may be carried by other biting insects such as fleas, mosquitoes and more.
