Enterobacteriaceae family

Since the structural determination of lipid A has focused on those of E. coli and S. typhimurium and that similar lipid A structures are reported to be present in the Enterobacteriaceae family, their lipid A structures are taken to be the prototype of... 

Trimethoprim-sulfamethoxazole is useful in the management of the Enterobacteriaceae family and also may be useful in the management of L. monocytogenes. One advantage of trimethoprim-sulfamethoxazole is that its penetration into the CSF does not depend on meningeal inflammation. Trimethoprim-sulfamethoxazole is not, however, bactericidal. Trimethoprim-sulfamethoxazole produces CSF levels of 1.9-5.7 mg/L for the former and 20-63 mg/L for the latter when given parenterally in doses of 10 mg/kg per day (trimethoprim) and 50 mg/kg per day (sulfamethoxazole). 

The carbohydrate O-specific side-chain moiety of the lipopolysaccharide (LPS) of a member of the Enterobacteriaceae family, Yokenella regensburgei,... 

The importance of microbiological indicators varies. The most important is the determination of microbes from the Enterobacteriaceae family and faecal streptococci. 

In another study (114), three different immobilization methods were evaluated for the detection of E. coli using an antibody coated crystal. The best results were obtained with a protein A coated method, and a response for 10 - lO cells 1 ml of E. coli K12 and other antigens of the Enterobacteriaceae family was observed. Repeated usage of the coated crystal by removing the bound antigen with urea or glycine HCl buffer (pH 2.6) was not very successful. 

The drug has exeellent potency against a majority of the members of the Enterobacteriaceae family, H. influenzae, Neisseria spp., andM catarrhalis. It is found to be not active against S. aureus or P. aeruginosa and exhibits mild streptococcal activity. It is invariably indicated in the management and control of community-acquired respiratory tract, minary tract and above all the gynecological infections. 

Like E. coli, Salmonella spp. is a member of the Enterobacteriaceae family often isolated from humans and food products. The various types of Salmonella spp are known pathogens. S. typhi causes typhoid fever while other species cause diarrhea or even septicemia. Its detection and identification therefore is important for food safety. Common food products that harbor Salmonella spp include eggs or poultry products that have not been properly processed or cooked.

Today the genus Citrobacter together with the genera Escherichia, Shigella Salmonella and Yersinia is included as an independent genus in the tribe Escherichieae of the Enterobacteriaceae family [5].
