Glycerol Fusin Test

The glycerol reddening test is a color change test method in which glycerol is decomposed by bacteria to produce pyruvic acid, pyruvic acid is decarboxylated to acetaldehyde, acetaldehyde and colorless reddish to form a quinoid compound, which is dark purple. It is mainly used for the identification of various strains in the genus Salmonella. Salmonella typhimurium, Salmonella paratyphi A, Salmonella choleraesuis, Salmonella serrata and Salmonella Sendai were negative in this test. The results of Salmonella paratyphimurium B were uncertain, and most other uncommon Salmonella were positive. Basic Information Specialist classification: Infectious disease inspection and classification: biochemical examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: Salmonella typhi, A (S) paratyphimurium, Salmonella choleraesuis, Salmonella sonne and Salmonella Sendai were negative. Positive: Most other uncommon Salmonella are positive. Tips: Maintain normal work and healthy eating habits. Normal value The normal type of the species and proportion of the flora in the intestine is normal. Salmonella is a group of G. faecalis that are parasitic in the gut of humans and animals. Most of them do not cause human diseases, and only a few are pathogenic. Such as typhoid Salmonella (typhoid bacillus) parahaemolyticus causing intestinal fever. Clinical significance It is mainly used for the identification of various strains in the genus Salmonella. Salmonella typhimurium, Salmonella paratyphi A, Salmonella choleraesuis, Salmonella serrata and Salmonella Sendai were negative in this test. The results of Salmonella paratyphimurium B were uncertain, and most other uncommon Salmonella were positive. Abnormal results can cause gastroenteritis, typhoid fever, bacteremia or sepsis in the clinic. Among them, intestinal fever is a legal infectious disease. 1. Enteric fever includes typhoid fever caused by Salmonella typhimurium and paratyphoid fever caused by Salmonella typhimurium A, B, and C. Mainly destroying the large intestinal mucosal cells, necrosis, causing different degrees of intestinal ulcers, bleeding, perforation and other complications. After Salmonella infection, it often causes gastroenteritis (food poisoning) and sepsis. The commonly used detection method is the fat test. 2, food poisoning caused by food poisoning Salmonella typhimurium, enteritis, pig cholera, B and C paratyphoid Salmonella are common. 3, chronic enteritis Salmonella can cause chronic enteritis in the elderly and children. 4, sepsis is caused by Salmonella choleraesuis. 5, local infection of Salmonella such as neck, waist, etc. The person in need of examination has the above symptoms. Negative results may be diseases: typhoid fever, paratyphoid fever Inappropriate crowd: no Taboo before check: Maintain normal work and healthy eating habits. Requirements for inspection: actively cooperate with the doctor Inspection process Method: The test bacteria in the in vitro culture solution of the tested site were inoculated into the glycerol complex red broth medium, and incubated at 35 ° C for 2-8 days. A negative control should be done at the same time. Results: The purple color was positive and was the same as the color of the control tube. Not suitable for the crowd no. Adverse reactions and risks no.
