Kluyvera

Kluyvera

 [kli´ver-ah]
a genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that are occasional opportunistic pathogens and cause respiratory and urinary infections.

Kluyvera

(klū'ē-ver'ă),
Genus in family Enterobacteriaceae; organisms are motile, lactose fermenting, and differentiated from other genera by specific phenotypic profiles and DNA-DNA hybridization parameters; some species have been associated with human infection; the type species is Kluyvera ascorbata.

Gram-negative bacteria pursue various molecular strategies for development of resistance to [beta]-lactam antibiotics: (a) generation of extended-spectrum [beta]-lactamases (ESBL) due to extension of the spectrum of already widely disseminated plasmid-encoded [beta]-lactamases by amino acid substitution; (b) acquisition of genes encoding ESBL from environmental bacteria as, for instance the CTX-M-type [beta]-lactamases from Kluyvera spp.
Of 17 studied animals, several members of the Enterobacteriaceae Family can be isolated (Table 2), including representatives of the genus Citrobacter, Enterobacter, Escherichia, Klebsiella, Kluyvera, Morganella, Proteus, Providencia, Salmonella and a Gram-negative facultative anaerobic rod, which is morphologically similar to the members of the Enterobacteriaceae family, Aeromonas, confirming some recorded findings for reptiles in the literature (McCoy and Seidler, 1973; Moreno et al.
Kluyvera is an opportunistic pathogen that can occur in immunosuppressed as well as immunocompetent hosts.
CTX-M-type [beta]-lactamases (CTX-Ms) are broad-spectrum [beta]-lactamases derived from the chromosomally encoded [beta]-lactamases of Kluyvera sp.

CTX-M]s are descended from a common ancestor that was incorporated in ancient times into the chromosome of the ancestor of Kluyvera species through horizontal transfer.
Among them, CTX-M-type ESBLs are rapidly expanding and are derived from chromosomal class A [beta]-lactamases of Kluyvera spp.
These enzymes probably evolved from chromosomal [beta]-lactamases of Kluyvera spp.
