An unusual case of Acanthamoeba Polyphaga and Pseudomonas Aeruginosa keratitis
UNLABELLED A 56-year-old woman with a history of disposable soft contact lens wear was referred to our university eye center for a corneal ulcer. Based on the microbial culture, the initial diagnosis was bacterial keratitis, which was unresponsive to topical fortified antibiotics. The patient was then examined using in vivo confocal microscopy, which revealed Acanthamoeba infection. This case e...
متن کاملSurvival of environmental mycobacteria in Acanthamoeba polyphaga.
Free-living amoebae in water are hosts to many bacterial species living in such an environment. Such an association enables bacteria to select virulence factors and survive in adverse conditions. Waterborne mycobacteria (WBM) are important sources of community- and hospital-acquired outbreaks of nontuberculosis mycobacterial infections. However, the interactions between WBM and free-living amoe...
متن کاملO-Linked glycosylation in Acanthamoeba polyphaga mimivirus.
Acanthamoeba polyphaga mimivirus is a member of the giant nucleocytoplasmic large DNA viruses, infecting various Acanthamoeba spp. The genomes of giant viruses encode components previously thought to be exclusive to cellular life, such as proteins involved in nucleic acid and protein synthesis. Recent work on enzymes involved in carbohydrate biosynthesis and metabolism show that instead of util...
متن کاملMeningitis caused by Pseudomonas paucimobilis.
This appears to be the first report of meningitis due to Pseudomonas paucimobilis and the first report of a clinically significant isolate of this species in the UK. Characteristics by which the species may be recognised are given, and attention is drawn to the possible confusion of Ps. paucimobilis with other yellow-pigmented pseudomonads and Flavobacterium species.
متن کاملGene&Genome Duplication in Acanthamoeba Polyphaga Mimivirus
Gene duplication is key to molecular evolution in all three domains of life and may be the first step in the emergence of new gene function. It is a well recognized feature in large DNA viruses, but has not been studied extensively in the largest known virus to date, the recently discovered Acanthamoeba Polyphaga Mimivirus. Here we present a systematic analysis of gene and genome duplication ev...
