Infrared spectrophotometry has been used for accelerated determination of sanitary-indicator microbes (Bugrova, 1965). A difference in the absorption bands in the range 2000 to 833 cm was established for three different families of bacteria Enterobacteriaceae Escherichia coli). Enterococci, and Staphylococci. Studies of the spectra of both entire microbe cells and of acetone extracts were conducted. The method must be used in conjunction with certain classical methods of bacteriological research to confirm the identity of the microorganisms.

A number of amide- and ester-linked fatty acids and (/ )-3-hydroxy acids are components of the lipid A part in the LPS from Gram-negative bacteria. The acids have been tabulatedand the chemistry of lipid A summarized. The most common acids in lipid A from Enterobacteriaceae are the saturated 12 0,14 0, and 16 0, and the (/ )-3-hydroxy-14 0, The last is linked to N-2 and 0-3 of the 2-amino-2-deoxy-D-glucopyranosyl residues, and the others are ester-linked to the hydroxy acid, as in the lipid A (44) of Salmonella minnesota. Other linear and branched fatty acids, unsaturated acids, S)-2- and (/ )-3-hydroxy acids, and 3-oxotetradecanoic acid are components of lipid A from certain different species. In the lipid A from Rhizobium trifolii, 2,7-dihydroxyoctanoic acid is linked as amide to a 2-amino-2-deoxy-D-gl ucopy ranosy 1 residue. ... 

MacConkey s medium. This was introduced in 1905 to isolate Enterobacteriaceae from water, urine, faeces, foods, etc. Essentially, it consists of a nutrient medium with bile salts, lactose and a suitable indicator. The bile salts function as a natural surface-active agent which, while not inhibiting the growth of the Enterobacteriaceae, inhibits the growth of Gram-positive bacteria which are likely to be present in the material to be examined. 

Among the family of Enterobacteriaceae, two species of the genus Erwinia define the soft rot group E. chrysanthemi and E. carotovora. The main characteristic of the soft rot bacteria is their ability to produce large quantities of plant cell wall degrading enzymes. The maceration of plant tissue resulting from...

Acute pancreatitis can progress to several distinct consequences. Pancreatic fluid collections and pancreatic abscesses can form during the course of acute pancreatitis. Pancreatic necrosis can occur when pancreatic enzymes damage the pancreatic tissue or when pancreatic abscesses become secondarily infected. This infection is usually due to bacteria that are normally found in the gastrointestinal tract, including Escherichia coli, Enterobacteriaceae, Staphylococcus aureus, viridans group streptococci, and anaerobes.
