[Diagnostic value of the acid production from galacturonate to differentiate strains of "Salmonella" sub-genus I and monophasic sub-genus III from the other "Salmonella" strains belonging to sub-genera II, diphasic III, IV, "Citrobacter" and "Hafnia alvei" (author's transl)]. 1979

Two methods were compared: (1) the ability to use sodium glacturonate as source of carbon and energy in defined medium; (2) the ability to produce acid by fermentation of this substrate in peptone water with phenol red. Results of growth on, acid formation from, galacturonate are identical. Salmonella strains of sub-genus I and monophasic serotypes of sub-genus III do not use galacturonate. Salmonella of sub-genera II and IV as well as diphasic serotypes of sub-genus III use galacturonate. Glacturonate-negative Salmonella are isolated mainly from man and warm-blooded animals whereas galacturonate-positive Salmonella are most often isolated from cold blooded animals and from the enrivonment. Citrobacter and Hafnia alvei which may be confused with Salmonella spp. are galacturonate-positive.

UI MeSH Term Description Entries
D002954 Citrobacter A genus of gram-negative, rod-shaped enterobacteria that can use citrate as the sole source of carbon.
D004755 Enterobacteriaceae A family of gram-negative, facultatively anaerobic, rod-shaped bacteria that do not form endospores. Its organisms are distributed worldwide with some being saprophytes and others being plant and animal parasites. Many species are of considerable economic importance due to their pathogenic effects on agriculture and livestock. Coliform Bacilli,Enterobacteria,Ewingella,Leclercia,Paracolobactrum,Sodalis
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
D005965 Glucuronates Derivatives of GLUCURONIC ACID. Included under this heading are a broad variety of acid forms, salts, esters, and amides that include the 6-carboxy glucose structure. Glucosiduronates,Glucuronic Acids,Acids, Glucuronic
D006603 Hexuronic Acids Term used to designate tetrahydroxy aldehydic acids obtained by oxidation of hexose sugars, i.e. glucuronic acid, galacturonic acid, etc. Historically, the name hexuronic acid was originally given to ascorbic acid. Hexouronic Acids,Acids, Hexouronic,Acids, Hexuronic
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.
D014574 Uronic Acids Acids derived from monosaccharides by the oxidation of the terminal (-CH2OH) group farthest removed from the carbonyl group to a (-COOH) group. (From Stedmans, 26th ed) Uronic Acid,Acid, Uronic,Acids, Uronic
