C. canimorsus and C. cynodegmi are commonly transmitted by dog bites and known to cause sepsis, potentially complicated by thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, in immunocompromised patients. [8] Other complications from infection can include heart attack, kidney failure, gangrene and amputation of limbs. [9]
C. canimorsus displays enhanced growth in high concentrations of carbon dioxide, so culturing the bacteria in candle extinction jars or carbon dioxide incubators is necessary. [4] To diagnose this bacillus, certain reactions may be tested. The bacterium should test positive for catalase and oxidase, arginine dihydrolase, maltose, and lactose.
Bacillus (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species.The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs.
R2A agar (Reasoner's 2A agar) is a culture medium [1] developed to study bacteria which normally inhabit potable water. [2] These bacteria tend to be slow-growing species and would quickly be suppressed by faster-growing species on a richer culture medium.
The test uses disks impregnated with a reagent such as N,N,N′,N′-tetramethyl-p-phenylenediamine, TMPD (or N,N-dimethyl-p-phenylenediamine, DMPD, which is also a redox indicator). The reagent is a dark-blue to maroon color when oxidized, and colorless when reduced.
The test was first developed and described by the German physician Felix Mendel in 1908. [2] It is named after Charles Mantoux, a French physician who built on the work of Koch and Clemens von Pirquet to create his test in 1907. However, the test was unreliable due to impurities in tuberculin which tended to cause false results. [3]
Voges–Proskauer / ˈ f oʊ ɡ ə s ˈ p r ɒ s k aʊ. ər / or VP is a test used to detect acetoin in a bacterial broth culture. The test is performed by adding alpha-naphthol and potassium hydroxide to the Voges-Proskauer broth, which is a glucose-phosphate broth that has been inoculated with bacteria. A cherry red color indicates a positive ...
The nitrate reductase test is a test to differentiate between bacteria based on their ability or inability to reduce nitrate (NO 3 −) to nitrite (NO 2 −) using anaerobic respiration. Procedure [ edit ]
