Taxonomy of Bacteria | Organisms | Microbiology

Medical textbooks are the last place to look for definitive taxonomic data. Medical sources are historically the most conservative in keeping abreast of changes in taxonomy and nomenclature. Such nomenclatural anachronisms as "Vibrio comma," "non-cholera vibrio," and "Salmonella typhosa" are examples of the ultraconservative approach of some medical sources to changes in nomenclature. The most comprehensive treatment of bacterial classification, [...]

3 Tests Employed for Serodiagnosis of Syphilis | Immunity | Microbiology

A number of tests are employed for the serodiagnosis of syphilis. Some of these are based on the complement-fixation technique; others are flocculation tests. The most important ones are known as: (1) The Wassermann test and its many modifications, (2) The Kahn test, and (3) The Kline test. 1. Wassermann Test: A complement-fixation test was proposed by Wassermann in which [...]

How do Bacteria Reproduce ? | Organisms | Microbiology

Bacteria reproduce by an asexual process called binary fission. In this sequence of events, the chromosome duplicates, the cell elongates, and the plasma membrane pinches inward at the center of the cell. When the nuclear material has been evenly distributed, the cell wall thickens and grows inward to separate the dividing cell. No mitotic structures (e.g., spindle, aster) are present [...]
