Predictors of Rates of Resistant Gram-Negative Bacteria

2014-07-24 14:07:23 | BioPortfolio

Summary

Antibiotic resistance in gram-negative bacteria continues to increase in US hospitals. This comes at a time when there are few new drugs in development that are active for these resistant organisms. The implication is that we must learn to use the drugs that we have more wisely and develop new strategies that will preserve existing agents. Antimicrobial "stewardship" programs are one strategy that many hospitals are adopting to improve the quality of antimicrobial use. The goal of this project is to develop a consortium of US academic medical centers that will allow characterization of the relationships between antibiotic use and rates of resistance for gram-negative pathogens, and to help hospital devise new strategies that will modify antibiotic use and possibly delay or reduce resistance.

The specific hypotheses are:

- Hospitals with established or emerging resistance in gram-negative pathogens, including extended spectrum beta-lactamase (ESBL) producing organisms, carbapenem-resistant enterobacteriaceae (CRE)and carbapenem-resistant P. aeruginosa have a different pattern of antimicrobial drug use compared to hospitals with fewer of these organisms.

- Hospital use of ertapenem is not associated with the rates of carbapenem-resistant organisms.

Evaluating death and activity decay of Anammox bacteria during anaerobic and aerobic starvation.

The decreased activity (i.e. decay) of anaerobic ammonium oxidation (Anammox) bacteria during starvation can be attributed to death (i.e. decrease in the amount of viable bacteria) and activity decay ...

Medical and Biotech [MESH] Definitions

The inter- and intra-relationships between various microorganisms. This can include both positive (like SYMBIOSIS) and negative (like ANTIBIOSIS) interactions. Examples include virus - bacteria and bacteria - bacteria.

A phylum of bacteria consisting of the purple bacteria and their relatives which form a branch of the eubacterial tree. This group of predominantly gram-negative bacteria is classified based on homology of equivalent nucleotide sequences of 16S ribosomal RNA or by hybridization of ribosomal RNA or DNA with 16S and 23S ribosomal RNA.

The presence of bacteria in the urine which is normally bacteria-free. These bacteria are from the URINARY TRACT and are not contaminants of the surrounding tissues. Bacteriuria can be symptomatic or asymptomatic. Significant bacteriuria is an indicator of urinary tract infection.

Bacteria resistant to high temperatures, as in PASTEURIZATION.

A genus of bacteria capable of developing within other bacteria.
