To elucidate the role of ameba-associated microorganisms (AAMs) as etiologic agents of pneumonia, we screened for Legionella spp., Parachlamydia acanthamoeba, Afipia sp., Bosea spp., Bradyrhizobium spp., Mesorhizobium amorphae, Rasbo bacterium, Azorhizobium caulinodans, Acanthamoeba polyphaga mimivirus, and conventional microorganisms in 210 pneumonia patients in intensive-care units by using c...

Background Acanthamoeba spp. is potentially pathogenic free-living amoeba that can exist in various water sources. The presence of this amoeba in water sources could be a health hazard as Acanthamoeba could lead to severe diseases such as Acanthamoeba keratitis and encephalitis. This study aimed to determine the genotypes of isolated Acanthamoeba spp. in raw wastewater samples in Tehran, Iran. ...

BACKGROUND Acanthamoeba spp. are free-living amoebae commonly found in the environmental sources such as water, soil, and air. This ubiquitous amoeba is the causative agent of amoebic keratitis (AK). The objective of the present study was to investigate the presence of Acanthamoeba spp. in water and soil sources in Ahvaz City, Khuzestan Province, southern Iran. METHODS In general, 110 samples...

PURPOSE Acanthamoeba keratitis (AK) is a painful and potentially blinding corneal infection caused by Acanthamoeba spp. In Madrid, environmental studies have demonstrated a high presence of these free-living amoebae in tap water. Since most of AK cases occur in contact lenses (CL) wearers with inadequate hygiene habits, the presence of Acanthamoeba in discarded CL has been studied and compared ...

Acanthamoeba causes opportunistic eye infections in humans, which can lead to severe keratitis and may ultimately result in blindness. Current methods for identifying this organism rely on culture and microscopy. In this paper, we describe the isolation of antibody fragments that can be used for the unequivocal identification of Acanthamoeba. A bacteriophage antibody display library was used to...

background: in this study morphological and molecular characterization of acan­thamoeba strains, isolated from dental unit waterlines (duwls) were surveyed and the levels of disinfection achievable in vitro by the application of ozone disinfect­ant to duwls were evaluate. methods: water samples were collected from air-water syringes, cup fillers and tap water before and at the end of the workin...

Acanthamoeba spp is one of the common protozoa in soil, usually found in fresh water and other habitats. We are presenting a case of Granulomatous amoebic encephalitis presented with unusual symptoms of third, fourth, sixth, and seventh nerve palsy with diplopia, ptosis, and migraine. Differential diagnosis of tuberculous (TB) meningitis was initially considered but was ruled out by CSF TB PCR....
