Acinetobacter baumannii is an important opportunistic nosocomial pathogen often resistant
to multiple antibiotics classes. Colistin, an “old” antibiotic, is now considered a last-line …

Acinetobacter baumannii is recognized as a clinically significant pathogen causing a wide
spectrum of nosocomial infections. Colistin was considered a last-resort antibiotic for the …

Abstract Objectives Colistin resistance in Acinetobacter baumannii has been associated with
loss of virulence and a negative impact on isolate selection. In this study, exposure of clinical …

Acinetobacter baumannii is a significant cause of opportunistic hospital acquired infection
and has been identified as an important emerging infection due to its high levels of …

Acinetobacter baumannii had emerged as an important nosocomial and opportunistic
pathogen worldwide. To assess the evolution of colistin resistance in A. baumannii and its …

The emergence of colistin-resistant Acinetobacter baumannii is concerning, as colistin is
often regarded as the last option for treating multidrug-resistant (MDR) A. baumannii …

The alarming rise in antibiotic resistance has led to an increase in patient mortality and
health care costs. This problem is compounded by the absence of new antibiotics close to …

Colistin is used as the “last resort” to treat infections caused by multidrug-resistant
Acinetobacter baumannii, which is at the top of the World Health Organization's list of the …

Two mechanisms of resistance to colistin have been described in Acinetobacter baumannii.
One involves complete loss of lipopolysaccharide (LPS), resulting from mutations in lpxA …

Colistin, which targets lipopolysaccharide (LPS), is used as a last-resort drug against severe
infections caused by drug-resistant Acinetobacter baumannii. However, A. baumannii …
