background: free-living amoebae (fla) including acanthamoeba spp. and hartmannella spp. are the causative agents of serious corneal infection especially within contact lens wearers. thus contact lenses and their storage case could be a suitable niche for potentially pathogenic amoebae. the main objective of the present study was to evaluate the contamination of contact lenses to free living amo...

background: free-living amoeba (fla)-related keratitis is a progressive infection of the cornea with poor prognosis. the present study aimed to investigates the con­tact lenses of patients with keratitis for pathogenic free-living amoebae. methods: overall, 62 contact lenses and their paraphernalia of patients with kerati­tis cultured and tested for the presence of free-living amoebae using mor...

background: free-living amoebae (fla) are a group of ubiquitous protozoan, which are distrib­uted in the natural and artificial environment sources. the main aim of the current study was to identify the presence of fla in the recreational hot springs of sarein in ardebil province of iran. methods: seven recreational hot springs were selected in sarein city and 28 water samples (four from each h...

background: free-living amoebae have various genera that are found in several environmental niches such as soil, freshwater, dust, seawater and hot springs. most of free-living amoebae are normally harmless to humans. however, some such as acanthamoeba and also naegleria fowleri , balamuthia manderillaris and sappinia are identified as opportunistic and pathogenic amoebae that can cause eye dis...

Buruli ulcer or Mycobacterium ulcerans disease occurs mainly in areas in proximity to standing or slowly running freshwater, habitats in which free-living amoebae occur. For this reason, a possible link between the habitat of M. ulcerans and free-living amoebae was investigated. Free-living amoebae and mycobacteria were isolated from water and biofilm specimens taken from protected and unprotec...

background: poor hygiene will provide good condition for corneal infections by opportunistic free-living amoebae (fla) in soft contact lens wearers. in the present study an amoebic keratitis due to hartmannella has been recognized in a 22-year-old girl with a history of improper soft contact lens use. she had unilateral keratitis on her left eye. her clinical signs were eye pain, redness, blurr...

BACKGROUND Free-living amoeba (FLA)-related keratitis is a progressive infection of the cornea with poor prognosis. The present study aimed to investigates the contact lenses of patients with keratitis for pathogenic free-living amoebae. METHODS Overall, 62 contact lenses and their paraphernalia of patients with keratitis cultured and tested for the presence of free-living amoebae using morph...

Free-living amoebae can harbour bacteria inside their cysts giving them a microhabitat and protecting them from disinfectants. The aim of this study was to evaluate the potential importance of "Limax amoebae" as vectors for environmental and nosocomial bacteria in a hospital. It was shown that free-living amoebae are ubiquitous in the investigated hospital, occur syntopically with facultative h...
