Acinetobacteris a physiologically and taxonomically diverse group that includes over 70 validly named species. These organisms are gram-negativeCoccobacilliand importanthuman pathogens. ManyAcinetobacterspp. are nonpathogenic and found as colonizers of plants andanimals.Acinetobacter calcoaceticus-baumannii(ACB...
Acinetobacter baumannii is resistant to all β-lactams with resistance being either intrinsic or acquired by transformation. The mechanisms of β-lactam resistance are complex, the most prevalent being enzymatic degradation by β-lactamases. In addition to enzymatic degradation, nonenzymatic mechanisms, ...
Like organisms such as Pseudomonas aeruginosa they are nonfermentative and thus can be readily differentiated by the clinical microbiology laboratory from the Enterobacteriaceae. The most important genomospecies is Acinetobacter calcoaceticus-baumannii complex. Acinetobacter spp. can actually be a normal ...
I gave a talk today at a meeting on combating carbapenem-resistant organisms. My angle was to clearly differentiate the epidemiology of the Enterobacteriaceae (i.e. CRE) from the non-fermenters (most importantly carbapenem-resistantA. baumannii– CRAB), and you can download my slideshere. I’v...
Acinetobacter baumannii (A. baumannii) is an opportunistic pathogen that poses dangerous health threat. It is a main cause of biofilm-associated infections that are mostly resistant to antibiotic therapy. Because of its capacity to form biofilm on biotic
25 August 2016 Yuan Hu1,2, Lihua He1,2, Xiaoxia Tao1,2, Fanliang Meng1,2 & Jianzhong Zhang1,2 Biofilm is recognized as a contributing factor to the capacity of Acinetobacter baumannii to persist and prosper in medical settings, but it is still unknown whether biofilms contribut...

Acinetobacterbaumanniiis a pathogenic species of this genus included in the Acb complex (Acinetobacter calcoaceticus-baumanniicomplex). It is responsible mainly for nosocomial (hospital-acquired) infections.A. baumanniiis Gram-negative, strictly aerobic, non-fermentative, usually non-motile, oxidase-negative...
baumannii (Acb) complex. Therefore, findings of studies in which species were identified only phenotypically should be interpreted with caution. Of the few methods that have been validated for identification of Acinetobacter species, DNA–DNA hybridization remains the reference standard. DNA–DNA ...
baumannii often exhibiting multidrug resistance have emerged as a significant clinical problem worldwide [2]. These organisms have been implicated in a diverse range of infections (respiratory tract, bloodstream, skin and soft tissue, prosthetic devices) and are a particular problem in intensive care ...
