Antimicrobial resistance risks from bacteria in 'Trojan horse' amoebae Amoebae living in a creek in Mumbai are acting as a "Trojan horse," harboring and protecting multidrug resistant bacteria, according to new research.

Weird word of the day: "kleptosquamy." The testate amoeba Awerintzewia cyclostoma steals scales from other amoeboid organisms to build its own shell. This one has robbed Quadrulella, Netzelia, various euglyphids, and even an Acanthocystis. Kleptosquamy! #amoebae #ProtistsOnSky #biology #nature

The amoeba Difflugia bacillifera builds its shell from things that contain silica, and it is not particular about the source. These ones have incorporated whole shells from another testate amoeba (Euglypha), along with diatoms, algal cysts and chunks of rock. #Amoebae #ProtistsOnSky #peatlands

Trojan Horse in Water: Amoebae as carriers for human Norovirus and Adenovirus In a new study titled “Enteric Viruses and Free-Living Amoebae: Protozoa as Potential Reservoirs and Transport Vessels for human Norovirus and Adenovirus,” published in Water & Ecology, an international team of researchers demonstrated that human norovirus (HNoV) and adenovirus (HAdV) can reside within environmental free-living amoebae (FLA) for up to 12 days. Viruses remained infectious within amoebae while encapsulated, protected from amoebal digestion and structural degradation. The detection of HAdV mRNA further suggests possible viral replication. These findings indicate that FLA may serve as environmental reservoirs and transmission vessels for enteric viruses—challenging the current water treatment efficacy and underscoring the need for updated public health guidance.

I broke some shells of Galeripora artocrea, to look at their algal hostages...and accidentally created Pac-Man amoebae. #amoebae #peatlands #ProtistsOnSky

Amoebae in the family Arcellidae make their shells from secreted vesicles of organic material that become hexagonal when pressed together. When a shell is broken, we can see inside the stiff-walled "areoles" that give it strength and durability. #ProtistsOnSky #Amoebae #peatlands

Last day in the field...time to wind down, pack up, put my stuff away. Of course, the sneaky shelled amoeba I've been chasing all week SUDDENLY decides to start blooming like crazy. #ProtistsOnSky #amoebae

But why does an amoeba need horns on its shell? They're quite carefully made, with flat plates neatly glued around them (possibly scales from another organism). The spheres around the mouth are siliceous resting cysts of chrysophyte algae. #ProtistsonSky #MEvoSky #Amoebae #Peatlands

Many amoebae incorporate diatoms in their shells, but Cylindrifflugia bacillariarum is the master. Third and fourth pics are close views of the glue that holds it all together. #ProtistsonSky #Amoebae #Peatlands

An amoeba with teeth. When building its shell, Netzelia corona selects sharp grains of quartz and positions them around its aperture with the tips pointing inward. I took a few closeups, yesterday. #ProtistsonSky #amoebae #peatlands #MEvoSky

Some specimens of a shelled amoeba called Heleopera sphagni, from a northern fen. The shell is assembled from jagged siliceous plates, but where did they come from? Stolen from a prey organism, or generated by the amoeba itself? I have no idea! #protistsonsky #amoebae #peatlands
