The exact nature of these symbionts and the benefit they represent for the amoebic host still have to be clarified. These include Legionella and Legionella-like pathogens. Giant viruses
The giant viruses Mimivirus, Megavirus, and Pandoravirus infect Acanthamoeba.Members of the genus Acanthamoeba are unusual in serving as hosts for a variety of giant viruses (that have more than 1000 protein-coding genes; for instance, Pandoravirus, which has about 2500 protein-coding genes in its genome). Diversity
Acanthamoeba can be distinguished from other genera of amoebae based on morphological characteristics. However, differentiating one species of Acanthamoeba from another by morphology has proven difficult. Based on 18S rDNA sequencing, known Acanthamoeba strains can be organized into 12 groups, denoted T1-T12. Most disease-causing isolates belong to type T4.Below is a list of described species of Acanthamoeba, with sequence types noted where known. Species that have been identified in diseased patients are marked with *.
Lipoatrophia semicircularis is a medical condition in humans, commonly known as ribbed thighs. It consists of a semicircular zone of atrophy of the subcutaneous fatty tissue located mostly on the front of the thighs. Skin and underlying muscles remains intact. Semicircular lipoatrophy mainly affects office workers. The ribs in the thighs are typically between 2 and 4 cm high and are typically located at about 72 cm above the ground, which is the standard height of office furniture. Cause
It is not yet clear what exactly causes semicircular lipoatrophy. Some hypotheses are that it is caused by localized pressure or by electromagnetic fields. Diagnosis
