Antigenic scheme of Citrobacter koseri.
An antigenic scheme, based on the determination of 17 somatic and 9 flagellar antigens, is proposed for Citrobacter koseri. Seven of the flagellar antigens constituted the specific phase (a through g), and the others (1 and 2) were nonspecific. Of the 238 theoretically possible serotypes, 48 were identified among 680 cultures examined.
متن کاملThe Frequency of Carbapenemase Genes in Citrobacter Frundii and Citrobacter Koseri Isolated from Clinical Specimens in Imam Reza Hospital, Kermanshah, Iran
Background & Aims: The inappropriate use of antibiotics has led to antibiotic resistance in microorganisms of Enterobacteriaceae family, especially in carbapenems. The aim of this study was to identify the carbapenemase producing Citrobacter frundii and Citrobacter koseri isolated from clinical specimens. Methods: One hundred Citrobacter isolates from various patient samples i...
متن کاملDraft Genome Sequences of blaKPC-Containing Enterobacter aerogenes, Citrobacter freundii, and Citrobacter koseri Strains
We report here the draft genome sequences of four blaKPC-containing bacteria identified as Klebsiella aerogenes, Citrobacter freundii, and Citrobacter koseri Additionally, we report the draft genome sequence of a K. aerogenes strain that did not contain a blaKPC gene but was isolated from the patient who had the blaKPC-2-containing K. aerogenes strain.
متن کاملNeonatal meningitis caused by Citrobacter koseri.
Three cases of neonatal meningitis, two of which were fatal, occurred in a premature baby unit during a period of one week. A fourth case occurred in the same unit six months later. Citrobacter koseri was isolated from the cerebrospinal fluid of all four cases. Detailed biochemical and serological examination of the organisms showed that two distinct bioserotypes were involved.
متن کاملSensitivity of Citrobacter freundii and Citrobacter koseri to cephalosporins and penicillins.
An examination of 99 field and reference strains of Citrobacter freundii showed 79% of them to be resistant to cephaloridine and sensitive to carbenicillin, while 96% of 45 field and reference strains of Citrobacter koseri examined were sensitive to cephaloridine and resistant to carbenicillin. Susceptibility tests with these two antibiotics are therefore useful in separating the two species of...
