How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

A time-resolved multi-omics atlas of Acanthamoeba castellanii encystment

Nature Communications, 2022
Encystment is a process that allows free-living and parasitic amoebae to survive in unfavorable environments. Here, Bernard et al. provide detailed insights into the early stages of encystment of Acanthamoeba castellanii by integrating RNA-Seq ...

Acanthamoeba species isolated from marine water in Malaysia exhibit distinct genotypes and variable physiological properties

Journal of Water and Health, 2022
The present study identifies the Acanthamoeba genotypes and their pathogenic potential in five marine waters in Malaysia. Fifty water samples were collected between January and May 2019. Physical parameters of water quality were measured in situ, whereas

Evolutionary Dynamics of Giant Viruses and their Virophages [PDF]

, 2013
Giant viruses contain large genomes, encode many proteins atypical for viruses, replicate in large viral factories, and tend to infect protists. The giant virus replication factories can in turn be infected by so called virophages, which are smaller ...

Endocannabinoids Inhibit the Growth of Free-Living Amoebae [PDF]

Antimicrobial Agents and Chemotherapy, 2010
ABSTRACTThe cannabinoid Δ9-tetrahydrocannabinol inhibits the growth of some pathogenic amoebaein vitroand exacerbates amoebic encephalitis in animal models. However, the effects of endogenous cannabinoids on amoebae remain unknown. Therefore, we tested several endocannabinoids (N-acyl ethanolamines and 2-O-acyl glycerol) on different genera of amoebae.

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin

Cytoskeleton, EarlyView.
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

Potentially Pathogenic Free-Living Amoebae in Contact Lenses of the Asymptomatic Contact Lens Wearers

Iranian Journal of Parasitology, 2014
Background: Free-living amoebae (FLA) including Acanthamoeba spp. and Hartmannella spp. are the causative agents of serious corneal infection especially within contact lens wearers. Thus contact lenses and their storage case could be a suitable niche for

Interactions of free-living amoebae with rice bacterial pathogens Xanthomonas oryzae pathovars oryzae and oryzicola. [PDF]

PLoS ONE, 2018
BACKGROUND:Free-living amoebae (FLA) are voracious feeders, consuming bacteria and other microbes during colonization of the phytobiome. FLA are also known to secrete bacteriocidal or bacteriostatic compounds into their growth environment.

Saline-Tolerant Pathogenic Acanthamoeba spp. Isolated from a Geothermal Power Plant

Pathogens, 2023
Few studies have been conducted in the cooling systems of power plants; they have focused on Naegleria fowleri, leaving a gap in the knowledge of other pathogenic free-living amoebae in this environment.

An Unfolding Story: AlphaFold's View on Protein Flexibility

Helvetica Chimica Acta, EarlyView.
AlphaFold confidence measures allow for detailed proteome‐wide characterization of protein flexibility. All flexibility measures increased substantially in the evolutionary transition from prokaryota to eukaryota. ABSTRACT The AlphaFold confidence measures are related to conformation distribution of the protein.
