Genetic Characterization of Atypical Citrobacter freundii
The ability of a bacterial population to survive in different niches, as well as in stressful and rapidly changing environmental conditions, depends greatly on its genetic content. To survive such fluctuating conditions, bacteria have evolved different mechanisms to modulate phenotypic variations and related strategies to produce high levels of genetic diversity. Laboratories working in microbi...
متن کاملComplete Genome of Citrobacter freundii Siphophage Stevie
Citrobacter freundii is an opportunistic pathogen responsible for many urinary tract infections acquired in hospitals and is thus a concern for public health. C. freundii phage Stevie might prove beneficial as a treatment against these infections. The complete genome of Stevie and its key features are described here.
متن کاملKinetic studies on inactivation of Citrobacter freundii cephalosporinase by sulbactam.
The inactivation kinetics for inhibition by sulbactam (CP45,899) of Citrobacter freundii GN346 cephalosporinase were studied in detail and compared with those of type Ib penicillinase or TEM-2 beta-lactamase mediated by R plasmid RGN823. The rate constant for progressive inactivation of the cephalosporinase was significantly larger than that measured with the penicillinase. The number of sulbac...
متن کاملIsolation and Characterization of Cytotoxic, Aggregative Citrobacter freundii
Citrobacter freundii is an infrequent but established cause of diarrhea in humans. However, little is known of its genetic diversity and potential for virulence. We analyzed 26 isolates, including 12 from human diarrheal patients, 2 from human fecal samples of unknown diarrheal status, and 12 from animals, insects, and other sources. Pulsed field gel electrophoresis using XbaI allowed us to div...
متن کاملNovel variants of the qnrB gene, qnrB22 and qnrB23, in Citrobacter werkmanii and Citrobacter freundii.
Resistance to quinolones in Gram-negative bacteria is usually mediated by the following: (i) chromosomal mutations that alter the target enzymes, DNA gyrase and topoisomerase IV, in their quinolone resistance-determining regions (QRDR), (ii) changes in drug entry (loss of porin channels), and (iii) the presence of plasmid-mediated quinolone resistance (PMQR) determinants [qnrA, qnrB, qnrS, qnrC...
