The current article makes a comparative analysis between the biodegradation of natural and synthetic polyethylene by three different species of Pseudomonas. The three Pseudomonas spp. (P1, P2, and P3) were indigenous to locations: (1) domestic waste disposal site dumped with household garbage and vegetable waste; (2) soil from textile effluents drainage site; and (3) soil dumped with sewage slu...

During 1997-2005, the microbiological quality and susceptibility of bacterial isolates of swimming pool waters were investigated. A total of 462 water samples were collected from three indoor swimming pools (a teaching pool, a competition public pool, a hydrotherapy pool) and two outdoor swimming pools (a hotel semi-public and a residential private pool) in Northwestern Greece. All water sample...

BACKGROUND Recent evidence indicates that Gram-negative bacterial pathogens, the most common of which are Pseudomonas spp., Enterobacteriaceae, and Acinetobacter baumannii, are frequent causes of hospital-acquired infections. This study aims to evaluate the in vitro activity of doripenem and comparator carbapenem antibiotics against Gram-negative clinical isolates collected from COMParative Act...

Cystic fibrosis (CF) predisposes patients to bacterial colonization and infection of the lower airways. Several species belonging to the genus Burkholderia are potential CF-related pathogens, but microbiological identification may be complicated. This situation is not in the least due to the poorly defined taxonomic status of these bacteria, and further validation of the available diagnostic as...

The methanolic leaf extract of Newbouldia laevis was subjected to preliminary phytochemical screening and in-vitro antimicrobial tests. The extract revealed the presence of flavonoids, tannins, terpenes, steroidal and cardiac glycosides. The antimicrobial activity of the plant extract was assayed by the agar plate disc diffusion and nutrient broth dilution techniques. Test microorganisms were P...

A total of 90 Pseudomonas aeruginosa strains isolated from 4 hospitals in the west-north region of Poland were studied by arbitrarily primed polymerase chain reaction (AP-PCR). AP-PCR results revealed the presence of 11 main groups of patterns (A-K) and 5 unique patterns among isolates. Generally, they were characterized by high resistance to antibiotics tested and significant differences in se...

This cross-sectional study, performed in an oncology hospital in Goiania, aimed to characterize the prevalence of oral colonization and antimicrobial susceptibility of Pseudomonas spp. isolated from the saliva of healthcare workers. Microorganisms were subjected to biochemical tests, susceptibility profile, and phenotypic detection. Of 76 participants colonized with Gram negative bacilli, 12 (1...

One of the global health issues is antibiotic resistance in Pseudomonas aeruginosa, a causative agent bacterial infections due to multidrug (MDR), which may be mediated by efflux pumps' overexpression.The present study investigated prevalence mexXY-oprM, mexPQ-opmE genes as encoding agents pumps and determination rate clinical isolates P. aeruginosa.Different specimens infectious patients, such...

The efficacy of strains of Pseudomonas fluorescens, Bacillus megaterium and Azospirillum spp. in in vitro solubilization of Ca3PO4 was studied. Pseudomonas fluorescens and Bacillus megaterium strains were the most powerful phosphate solubilizers on Pikovskaya (PVK) plates and liquid medium. Azospirillum lipoferum strains showed weak zones of solubilization on the PVK plates. Phosphate solubiliz...

Introduction: The strains of Pseudomonas aeruginosa are known as an opportunistic pathogen that can cause infections in humans and animals. Metallo-β-lactamases (MBLs) are the most significant factors of resistance to carbapenem antibiotics in these bacteria. This study was designed to identify the MBLs producing P. aeruginosa isolates in three hospitals of Tehran, Iran. Methods: Tota...
