Some amoebae are predatory and live by consuming bacteria and other protists. Some are detritivores and eat dead organic material. Amoebae typically ingest their food by phagocytosis, extending pseudopods to encircle and engulf live prey or particles of scavenged material.

Amoebae have evolved different mechanisms to find, kill, and digest bacteria, while bacteria also developed strategies to resist amoeba predation and, in return, sometimes to infect and kill amoebae. We can learn a lot from the long-term coevolution between amoebae and bacteria.

2020年10月29日 · It is a free-living, bacteria-eating microorganism that can be pathogenic, causing an extremely rare fulminant and fatal brain infection called naegleriasis, also known as primary amoebic meningoencephalitis.

2022年2月26日 · "Most of the known amoebae eat bacteria," Maciver told Live Science. He explained that amoebas have receptors on their cell surface that bind to bacteria, which are then taken into amoebas by...

2019年1月17日 · How exactly the amoebas and bacteria interact in the soil is an important question, particularly as some of the bacteria can also live inside amoebas. Does this intimate relationship help or harm the amoeba?

2024年9月19日 · Amoebas are fascinating single-celled organisms that thrive in diverse environments. They belong to the kingdom Protista and exhibit remarkable adaptability. These microscopic entities move and feed using pseudopodia, which are temporary projections of their cytoplasm. Amoebas play crucial roles in ecosystems as both predators and prey.

2021年1月4日 · Amoebae are protists that have complicated relationships with bacteria, covering the whole spectrum of symbiosis. Amoeba-bacterium interactions contribute to the study of predation, symbiosis, pathogenesis, and human health.
