In cystic fibrosis (CF) patients early antibiotic treatment of lung infection has been shown to lead to Pseudomonas aeruginosa eradication. The present study determined: 1) the time period from eradication to new P. aeruginosa acquisition; 2) P. aeruginosa re-growth and new acquisition; and 3) the impact of eradication therapy on lung function, antimicrobial resistance, emergence of other patho...

The aim of the present study was to investigate the molecular mechanism of carbapenem resistance in Pseudomonas aeruginosa and Acinetobacter baumannii clinical isolates recovered from Libyan hospitals between April 2013 and April 2014. In total, 49 strains (24 P. aeruginosa and 25 A. baumannii) were isolated, including 21 P. aeruginosa and 22 A. baumannii isolates (87.75%) resistant to imipenem...

Serum samples from 57 patients with cystic fibrosis were tested for the presence of IgG, IgA, IgM, IgE, and circulating immune complexes containing IgG, IgA, and IgM. Titres of class specific antibodies to Pseudomonas aeruginosa, and class specific antibodies to Ps aeruginosa in circulating immune complexes, were also measured. According to the Shwachman score the patients were divided into thr...

Growth of Pseudomonas aeruginosa and thirty-five other species of gramnegative bacilli was observed on 0.03% cetrimide in heart infusion agar medium and Pseudosel agar (BBL). The 0.03% cetrimide agar was more selective for growth of P. aeruginosa than was Pseudosel agar; however, certain bacteria other than P. aeruginosa also grew on the former medium. Although Pseudosel agar was not a highly s...

Pseudomonas aeruginosa strains exhibit significant variability in pathogenicity and ecological flexibility. Such interstrain differences reflect the dynamic nature of the P. aeruginosa genome, which is composed of a relatively invariable "core genome" and a highly variable "accessory genome." Here we review the major classes of genetic elements comprising the P. aeruginosa accessory genome and ...

Ecthyma Gangrenosum is a severe skin disease commonly associated with Pseudomonas aeruginosa septicemia, there an increased risk of infection in patients malignancy undergoing chemotherapy notably Chronic lymphocytic leukemia (CLL). We present case report CLL patient infested by P. aeruginosa.

BACKGROUND The incidence of Pseudomonas aeruginosa bacteremia has not been defined in a population-based investigation. METHODS We performed a retrospective, population-based incidence study using resources of the Rochester Epidemiology Project of Olmsted County, Minnesota. We identified all Olmsted County residents with P. aeruginosa bacteremia between January 1, 1997, and December 31, 2006,...

BACKGROUND Patients with severe chronic obstructive pulmonary disease (COPD) are at increased risk of infection by P. aeruginosa. The specific role of bronchiectasis in both infection and chronic colonization by this microorganism in COPD, however, remains ill defined.To evaluate the prevalence and risk factors for P. aeruginosa recovery from sputum in outpatients with severe COPD, characterizi...

The aerobic gram negative bacterium Pseudomonas aeruginosa is an opportunistic pathogen responsible for life threatening acute and chronic infections in humans. As part of chronic infection P. aeruginosa forms biofilms, which shield the encased bacteria from host immune clearance and provide an impermeable and protective barrier against currently available antimicrobial agents. P. aeruginosa ha...
