Background and Aim: Vermamoeba vermiformis is an opportunistic free living amoeba(FLA) that is ubiquitous in different environmental sources. This Amoeba can cause Amoebic Keratitis(AK) and Granulomatous Amoebic Encephlitis (GAE) in immunocompromised patients. This study was conducted to determine the rate of Vermamoeba vermiformis in stagnant water and soil in Arak. Materials and Methods:  In...

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...

Data on the distribution of free-living amoebae is still lacking especially in Southeast Asian region. The aquatic environment revealed a high occurrence of free-living amoebae (FLA) due to its suitable condition and availability of food source, which subsequently causes infection to humans. A total of 94 water samples consisted of both treated and untreated from Laos (31), Myanmar (42), and Si...

BACKGROUND The repertoire of free-living protozoa in contact lens solutions is poorly known despite the fact that such protozoa may act as direct pathogens and may harbor intra-cellular pathogens. METHODS Between 2009 and 2014, the contact lens solutions collected from patients presenting at our Ophthalmology Department for clinically suspected keratitis, were cultured on non-nutrient agar ex...

Abstract Free-living amoebae (FLA) are protozoa dispersed in different environments and responsible for infections caused to humans other animals. Microorganisms such as Acanthamoeba spp., Vermamoeba sp., Naegleria sp. associated with diseases that affect the central nervous system, addition skin keratitis, occurs genus vermiformis. Due concerns of these FLA anthropogenic aquatic environments, ...

background: free-living amoebae (fla) are protozoa that are widely distributed in the environment mainly in water and soil related habitats. thermophilic amoebae are among the most common fla in water bodies, being vermamoeba vermiformis one of the most common species reported worldwide from these sources. interestingly, v. vermiformis has often been reported to survive at high temperatures and...

Amoeba-associated microorganisms (AAMs) are frequently isolated from water networks. In this paper, we report the isolation and characterization of Protochlamydia massiliensis, an obligate intracellular Gram-negative bacterium belonging to the Parachlamydiaceae family in the Chlamydiales order, from a cooling water tower. This bacterium was isolated on Vermamoeba vermiformis. It has a multiple ...
