Salmonella typhosa

Alcohols, particularly ethanol [64-17-5] and 2-propanol [67-63-9] are important disinfectants and antiseptics. In the aUphatic series of straight-chain alcohols, the antimicrobial activity increases with increasing molecular weight up to a maximum, depending on the organism tested. For Staphylococcus aureus the maximum activity occurs using amyl alcohol [71-41-0], for Salmonella typhosa, octyl alcohol [111-87-5], CgH gO (43) ioT Mycobacterium tuberculosis... 

Eig. 1. The quasispeciftc effect ia the homologous series of o-alkyl-/)-chloropheaol derivatives agaiast A = Salmonella typhosa-, B = Staphyloccus aureus-, C = Mycobacterium tuberculosis-, D = Candidaalbicans. Pheaol coefficieat is the activity of the chemical tested compared to that of pheaol.

Kav is the availability constant of a substance with molecular weight M, Ve is the elution volume, Vt is the total volume of the column, V0 is the void volume or the interstitial space between the beads in the bed. The void volume could not be determined by the elution volume of Blue Dextran 2000 (Pharmacia Fine Chemicals AB, Uppsala, Sweden, Mw about two million) since it would have separated in the column. We used a 0.5% lipopolysaccharide solution (Bacto Lipopolysaccharide W, Salmonella typhosa 0901 ref. nr. 3124-25, Difco Laboratories, Detroit, MI, USA) with a molecular weight of above 150,000,000, which is excluded by the gel. 

In another study of Salmonella typhosa and Salmonella paratyphi B antisera, which used their ability to precipitate various polysaccharides of known or partly known structure, quite different conclusions were arrived at in each of these polysaccharides, both D-galactose and D-mannose were considered to be present as nonreducing end-groups. ... 

Material prepared from Salmonella typhosa, Escherichia coli, and Para-colobactrum ballerup gave closely similar infrared spectra and seemed in other ways identical satisfactory electrophoretic patterns were obtained, and a molecular weight of about 10 was deduced. 

Bacteria are both harmful and beneficial. They degrade the waste-products produced by society. They are used in wastewater treatment plants— thus, they are beneficial. On the other hand, they can also be pathogenic. The bacteria. Salmonella typhosa, causes typhoid fever Shigella flexneri causes bacillary dysentery. Clostridium tetani excretes toxins producing tetanus. Clostridium botulinum excretes the toxin causing botulism. Corynebacterium diphtheriae is the agent for diphtheria. 

The bacteria may be motile in one medinm and nonmotile in another also, it may be motile at one temperatnre bnt nonmotile at another. Salmonella typhosa, a bacillns that canses typhoid fever, moves at a rate of abont 2,000 times its length in one honr.

They are generally toxic to most body tissues, and are less potent than exotoxins. They are typified by the following, Escherichia coli (wound infection and septicaemia), Klebsiella pneumoniae (urogenital tract infections). Shigella dysenterlae (dysentery). Salmonella typhosa (typhoid fever), Pasteurella pestis (bubonic plague) and Pseudomonas aeruginosa (wound infections and septicaemia). Not all of these endotoxins are fully characterized, and some toxic mechanisms are obscure. 

Acetamido-2-deoxy-D-galacturonic acid, a major immunogenic component of Salmonella typhosa [2], was the first naturally occurring amino hexuronic acid identified [3]. In 1962 Perkins reported that the cell wall of Micrococcus lysodeikticus...
