The sero-fermentative-phage types of Salmonella weltevreden. 1980

D N Garg, and D N Bhargava, and V K Sharma

A biotyping scheme has been described which is based on the biochemical behaviour of S. weltevreden strains towards 5 substrates (sorbitol, dextrin, malonate, rhamnose, starch). The 228 S. weltevreden strains examined were grouped into 25 of the 32 theoretical biotypes. Frequently occurring biotypes were: biotype 10 (16.2%), biotype 5 (13.4%) and biotype 11 (11.4%). No substantial correlation could be established between biotypes and source or geographic distribution of S. weltevreden. Sero-fermentative-phage types were computed for 145 strains, phage-types of which has been described earlier and five predominant sero-fermentative-phage types emerged. The sero-fermentative-phage type 3, 10:r:z6;5;1 (serotype = 3, 10:r:z6; biotype = 5; phagetype =1) occurred most commonly with a frequency of 10.3%. The strains belonging to this pattern were from lizard, guinea-pig and humans in India, Netherlands and United States of America.

UI	MeSH Term	Description	Entries
D008314	Malonates	Derivatives of malonic acid (the structural formula CH2(COOH)2), including its salts and esters.
D003912	Dextrins	A group of low-molecular-weight carbohydrates produced by the hydrolysis of STARCH or GLYCOGEN. They are mixtures of polymers of D-glucose units linked by alpha-(1->4) or alpha-(1->6) glycosidic bonds.	Dextrin
D005285	Fermentation	Anaerobic degradation of GLUCOSE or other organic nutrients to gain energy in the form of ATP. End products vary depending on organisms, substrates, and enzymatic pathways. Common fermentation products include ETHANOL and LACTIC ACID.	Fermentations
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D001434	Bacteriophage Typing	A technique of bacterial typing which differentiates between bacteria or strains of bacteria by their susceptibility to one or more bacteriophages.	Phage Typing,Typing, Bacteriophage,Typing, Phage
D012210	Rhamnose	A methylpentose whose L- isomer is found naturally in many plant glycosides and some gram-negative bacterial lipopolysaccharides.	Deoxymannose,Rhamnose, L-Isomer,Rhamnose, L Isomer
D012475	Salmonella	A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that utilizes citrate as a sole carbon source. It is pathogenic for humans, causing enteric fevers, gastroenteritis, and bacteremia. Food poisoning is the most common clinical manifestation. Organisms within this genus are separated on the basis of antigenic characteristics, sugar fermentation patterns, and bacteriophage susceptibility.
D012703	Serotyping	Process of determining and distinguishing species of bacteria or viruses based on antigens they share.	Serotypings
D013012	Sorbitol	A polyhydric alcohol with about half the sweetness of sucrose. Sorbitol occurs naturally and is also produced synthetically from glucose. It was formerly used as a diuretic and may still be used as a laxative and in irrigating solutions for some surgical procedures. It is also used in many manufacturing processes, as a pharmaceutical aid, and in several research applications.	Glucitol,Medevac,Sorbilax,Yal,klysma Sorbit
