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 ...

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...

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 group of protozoa distributed worldwide in many habitats mainly water and soil related sources. some members of fla are able to act as opportunistic pathogens and are environmental carriers of other pathogenic agents such as bacteria and viruses. vermamoeba vermiformis is a highly abundant fla species in water bodies and has recently gained environmenta...

In this study, we report the isolation of a new giant virus found in sewage water from the southern area of Jeddah (Saudi Arabia), with morphological and genomic resemblance to Faustoviruses. This new giant virus, named Kaumoebavirus, was obtained from co-culture with Vermamoeba vermiformis, an amoeboid protozoa considered to be of special interest to human health and the environment. This new ...

A model was developed to study the multiplication of various Legionella spp. in tap water containing Hartmannella vermiformis. Tap water cultures prepared with the following components were suitable for the multiplication studies: Legionella spp., 10(3) CFU/ml; H. vermiformis, 10(4.4) cysts per ml; and killed Pseudomonas paucimobilis, 10(9) cells per ml. Cocultures were incubated at 37 degrees ...
