BACKGROUND Chronic infection with Pseudomonas aeruginosa in patients with cystic fibrosis (CF) is associated with increased morbidity. Chronic infection can cause limb and respiratory muscle compromise. Respiratory muscle function can be assessed via maximal inspiratory pressure (PImax), maximal expiratory pressure (PEmax), and the pressure-time index of the respiratory muscles (PTImus). We stu...
We previously reported an outbreak in a neurosurgery ward of catheter-associated urinary tract infection with multidrug-resistant (MDR) Pseudomonas aeruginosa strain IMCJ2.S1, carrying the 6'-N-aminoglycoside acetyltransferase gene [aac(6')-Iae]. For further epidemiologic studies, 214 clinical isolates of MDR P. aeruginosa showing resistance to imipenem (MIC >or= 16 microg/ml), amikacin (MIC >o...
Pseudomonas aeruginosa PAO1 produces three polysaccharides, alginate, Psl, and Pel that play distinct roles in attachment and biofilm formation for monospecies biofilms. Considerably less is known about their role in the development of mixed species biofilm communities. This study has investigated the roles of alginate, Psl, and Pel during biofilm formation of P. aeruginosa in a defined and exp...
Pseudomonas aeruginosa is an opportunistic human pathogen capable of forming a biofilm under physiological conditions that contributes to its persistence despite long-term treatment with antibiotics. Here, we report that pathogenic P. aeruginosa strains PAO1 and PA14 are capable of infecting the roots of Arabidopsis and sweet basil (Ocimum basilicum), in vitro and in the soil, and are capable o...
BACKGROUND Cystic Fibrosis (CF) patients are vulnerable to airway colonization with Pseudomonas aeruginosa. In case eradication fails after antibiotic treatment, patients become chronically colonized with P. aeruginosa, with recurrent pulmonary exacerbation, for which patients typically are hospitalized for 2 weeks and receive intravenous antibiotic treatment. Normally, improvement of the patie...
Messadi AA, Lamia T, Kamel B, Salima O, Monia M, Saida BR. Association between antibiotic use and changes in susceptibility patterns of Pseudomonas aeruginosa in an intensive care burn unit: a 5-year study, 2000-2004. Burns :J Int Soc Burn Injuries 2008;34(8):1098-102. Sherertz RJ, Sarubbi FA. A three-year study of nosocomial infections associated with Pseudomonas aeruginosa. J Clin Micr...
استفاده از میکروارگانیسم ها یکی از راه های عملی در کاهش آلودگی های نفتی می باشد. برخی از میکروارگانیسم ها با تولید بیوسورفاکتانت از طریق ازدیاد میزان انحلال پذیری هیدروکربن ها در فاز آبی، باعث افزایش تجزیه زیستی می شوند. به منظور بررسی رشد و تولید بیوسورفاکتانت و تجزیه آنتراسن توسط باکتری های ساکن در رسوبات آلوده خور موسی و همچنین مطالعه رشد آن ها، نمونه های رسوب از منطقه اخذ شد. هشت گونه باکتر...
Recent isolation of Pseudomonas aeruginosa strains from the open ocean and subsequent pulsed-field gel electrophoresis analyses indicate that these strains have a unique genotype (N. H. Khan, Y. Ishii, N. Kimata-Kino, H. Esaki, T. Nishino, M. Nishimura, and K. Kogure, Microb. Ecol. 53:173-186, 2007). We hypothesized that ocean P. aeruginosa strains have a unique phylogenetic position relative t...
The influence of nitrogen on the interactions between amoxicillin and Microcystis aeruginosa was investigated using a 7-day exposure test. Growth of M. aeruginosa was not significantly (p>0.05) affected by amoxicillin at the lowest nitrogen level of 0.05 mg L(-1), stimulated by 500 ng L(-1) of amoxicillin at a moderate nitrogen level of 0.5 mg L(-1) and enhanced by 200-500 ng L(-1) of amoxicill...
Microcystis aeruginosa causes surface blooms in eutrophic lakes in the tropical and temperate zones. We investigated which factors suppressed blooms of M. aeruginosa in Lake Kasumigaura, a shallow hypereutrophic lake in the temperate zone of Japan, from 1999 to 2007 by quantifying the 16S rRNA gene of M. aeruginosa using real-time PCR. These results showed that M. aeruginosa existed in the lake...
