Nasal Carriage of Free-Living Amoebae [PDF]
Microbial Ecology in Health and Disease, 1988 South Australia has had a relatively high frequency of human disease caused by free-living amoebae. The prevalence of these organisms in the nasal mucosa of 262 asymptomatic adult volunteers was determined. Acanthamoeba was isolated from six (2.3 per cent) subjects. This carriage rate is not high in comparison to other studies. Keywords: Free-living

Polyamines biosynthesis and oxidation in free-living amoebae
Amino Acids, 2004In this paper we describe the polyamine biosynthesis and oxidation processes, giving an overview about recent results in free-living Amoebae. The protozoa polyamine levels are different in comparison with mammalian cells. Also, the polyamine levels in protozoa cells change if these species are pathological or not for the human beings.

OBSERVATIONS ON THE CULTURE AND MAINTENANCE OF A FREE-LIVING AMOEBA
Canadian Journal of Microbiology, 1956A free-living amoeba isolated from creek water could be grown at 24 °C. on a solid malt agar medium together with a pure culture of a motile Gram-negative bacillus, isolated from the same sample of water. The bacilli apparently served as the sole source of food for the trophozoites, the malt in the medium being-utilized by the bacilli for their own ...

Viruses in close associations with free-living amoebae
Parasitology Research, 2015As both groups of organisms, free-living amoebae (FLA) and viruses, can be found in aquatic environments side by side, it appears obvious that there are multiple interactions with respect to host-endocytobiont relationships. Several relationships between viruses and protozoan hosts are described and it was the discovery of the so called "giant viruses,"

The biochemical composition of the free-living Amoebae Chaos chaos, amoeba dubia and Amoeba proteus
Comparative Biochemistry and Physiology, 1968Abstract 1. 1. The biochemical compositions of the free-living amoebae Chaos chaos, Amoeba dubia , and Amoeba proteus were determined. 2. 2. The percentages of protein, phospholipid and RNA per dry weight were different in each species. 3. 3.

A phylogenetic study of the free-living amoeba
Biochemical Systematics and Ecology, 1984Abstract Immunological distances were determined for four strains of the free-living amoeba classified as Amoeba proteus , two strains classified as Polychaos dubia and a single strain classified as Chaos carolinensis . The data show that the Sh P strain does not belong to the proteus group; that A.

Free-Living Amoebae in Southeast Asia
2013In Southeast Asia (SEA), human infections caused by free-living amoebae (FLA) such as species of Acanthamoeba, Naegleria, Balamuthia, Vahlkampfia and Hartmannella were occasionally reported. To date, human cases or research work on these FLA have only been detected or performed in five countries which were Thailand, Malaysia, Singapore, Vietnam and the

Study of free living amoebae in Egypt.
Journal of the Egyptian Society of Parasitology, 1994At different locality in Egypt, free living amoebae (FLA) were detected in 32%, 20% and 4% of water samples obtained from swimming pools, surface water canals and tap water respectively. Naegleria spp. were identified from 12 (75%) out of 16 swimming pool samples and 6 (60%) out of 10 surface water & canals samples from different Governorates in Egypt,
