Draft Genome Sequences of Multidrug-Resistant Acinetobacter sp. Strains from Colombian Hospitals.

The draft genome sequences of the strains Acinetobacter baumannii 107m, Acinetobacter nosocomialis 28F, and Acinetobacter pittii 42F, isolated from Colombian hospitals, are reported here. These isolates are causative of nosocomial infections and are classified as multidrug resistant, as they showed resistance to four different antibiotic groups.

Antibiotic resistance patterns of Acinetobacter calcoaceticus-A. baumannii complex species from Colombian hospitals.

Introduction: Only automated phenotypic methods are currently used in Colombian hospitals for identifying isolates of the Acinetobacter calcoaceticus-A. baumannii complex (ACB). The phenotypical similarities in these species mean that they cannot be differentiated by manual or automated methods, thereby leading to their identification as A.

[Distribution of extended spectrum β-lactamases-codifying genes in Klebsiella pneumoniae isolates from hospitals of Bogota, D.C., Colombia].

Introduction: Extended spectrum β-lactamases (ESBL) are the most widely distributed enzymes in Enterobacteriaceae of Latin America and are key enzymes in resistance to antibiotics in common use. However, in Colombia, little information is available concerning the identity of genes coding for these enzymes in Klebsiella pneumoniae.

Objective: The bla genes were identified in K.

[Resistance to cefepime in Enterobacter cloacae isolates from hospitals in Bogotá, Colombia].

Objective: The aim of this research was to detect the presence of genes encoding beta-lactamases which can confer cefepime resistance on Enterobacter cloacae isolates, meaning that this antibiotic may be considered an important therapeutic alternative.

Materials And Methods: 28 E. cloacae isolates collected from 4 hospitals in Bogotá during 2003 were analysed.

[Molecular epidemiology of nosocomial infection by extended-spectrum beta-lactamases-producing Klebsiella pneumoniae].

Molecular epidemiology applied to the study of nosocomial infection has been fundamental in formulating and evaluating control methods. From patients in a level 3 Bogota hospital, Klebsiella pneumoniae samples were isolated that produced extended-spectrum beta-lactamases (ESBL). Each of 15 isolates was characterized microbiologically and by molecular characters realized by pulsed field gel electrophoresis (PFGE) and by repetitive-DNA sequences amplification (REP-PCR).
