Acinetobacter baumannii is a pleomorphic aerobic gram-negative bacillus (similar in appearance to Haemophilus influenzae on Gram stain) commonly isolated from the hospital environment and hospitalized patients. A baumannii is a water organism and preferentially colonizes aquatic environments. It is also a ...
or Moraxella on Gram stain. Common in the environment (water, soil) and hospitals (catheters, lotions, ventilation equipment) Grows on standard agar media. Oxidase negative A. baumannii is the major species of Acinetobacter. Other species include A. calcoaceticus, A. lwoffi, A. junii, A....
A. baumannii is an aerobic, Gram-negative coccobacillus that is considered part of the normal human flora of the skin and mucous membranes of the pharynx, human respiratory secretions, urine and rectum[4]. Of interest, Acinetobacter species are the only Gram-negative bacteria that are considered...
We present a patient with fulminant community-acquired pneumonia (CAP) caused by Acinetobcter baumannii . This case presented several challenges to the laboratory because of atypical features encountered during identification of the causative organism. Case Report A 68-year-old woman presented to the ...
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
Acinetobacter baumannii (AB) is rising as a human pathogen of critical priority worldwide as it is the leading cause of chronic opportunistic infections in healthcare settings and the condition is ineradicable with antibiotic therapy. AB possesses the ab
The role of Acinetobacter baumannii in infections in ventilated preterm infants was evaluated in 15 colonized infants (11 male, 4 female) in a pediatric intensive care unit. These cases were randomly matched by birth weight and gestational age with ventilated non-colonized controls (8 male, 7 fem...
Acinetobacter baumannii infects critically ill patients with a mortality rate of 20–60%, although the extent to which A. baumannii infection contributes to the rate of mortality is uncertain. Even though the involvement of Acinetobacter spp. in bacteremia, pulmory infections, meningitis, and...
“How important is the environment in the transmission of resistant Gram-negatives?”Again, this depends on which Gram-negative you’re talking about. ForA. baumanniithe answer is probably “very important” whereas for the Enterobacteriaceae the answer is more like“quite important”. ...
Acinetobacter baumannii is a critical opportunistic pathogen associated with nosocomial infections. The high rates of antibiotic-resistance acquisition make most antibiotics ineffective. Thus, new medical countermeasures are urgently needed. Outer membra
