La phagothérapie, une technique médicale pratiquée depuis environ un siècle, n'est encore étayée que par peu de preuves cliniques et les quelques études sur le sujet ont abouti à des résultats mitigés. Corpus ID: 84002388. Objectives: The aim of this study was to report clinical experience of infections due to ESBL-negative OXA-48-producing Klebsiella pneumoniae (K. pneumoniae) treated with cephalosporins. These infections most commonly occur in people with exposure to healthcare, including those in hospitals and nursing homes. The spread of carbapenemase-producing organisms threatens to extend carbapenem resistance to the community (14). Resistance to carbapenems might have been underreported at the beginning of our study period because of a lower frequency of susceptibility testing of these agents and the inability of antimicrobial susceptibility test methods to detect low-level carbapenem resistance. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website.

We used χ2 testing to determine whether changes in K. pneumoniae antimicrobial drug resistance were statistically significant from 2000 to 2010 and whether 2010 antimicrobial drug resistance differed by specimen source. Data for tigecycline that used FDA interpretive breakpoints showed K. pneumoniae antimicrobial drug resistance was 2.6% in 2010. Because of a lack of Clinical Laboratory Standards Institute or FDA interpretive breakpoints for K. pneumoniae and colistin or fosfomycin, these data were not collected by TSN Database-USA and were not included in this study. In our analysis of cross-resistance among imipenem-resistant K. pneumoniae, tetracycline had the greatest antimicrobial activity against CRKP. La pneumonie, qui correspond à une infection aiguë des poumons, peut être causée par une bactérie ou un virus.Ces agents infectieux atteignent les alvéoles pulmonaires, zones de transfert de l'oxygène ressemblant à des ballons qui se localisent à l'extrémité des bronchioles.Les alvéoles se remplissent alors de liquide, ce qui provoque les symptômes de la pneumonie.
