Decryption of the survival “black box”: gene family expansion promotes the encystment in ciliated protists [PDF]

BMC Genomics
Background Encystment is an important survival strategy extensively employed by microbial organisms to survive unfavorable conditions. Single-celled ciliated protists (ciliates) are popular model eukaryotes for studying encystment, whereby these cells ...

PRMT5 Inhibitor EPZ015666 Decreases the Viability and Encystment of Entamoeba invadens [PDF]

Molecules
Protein arginine methyltransferase 5 (PRMT5) is an enzyme that produces monomethyl arginine (MMA) and symmetric dimethyl arginine (sDMA), post-translational modifications that regulate several cellular processes, including stage conversion in parasitic ...

Lesion Profiles and Tissue Pathology of Clinostomum Metacercariae in Oreochromis niloticus From Lake Tana and An Adjacent Aquaculture Pond, Bahir Dar, Ethiopia. [PDF]

Vet Med Sci
A cross‐sectional study assessed Clinostomum metacercariae–associated lesions in 72 Nile tilapia from Lake Tana and adjacent aquaculture ponds. Cysts were predominantly found in muscle, followed by gills and liver. Histopathology revealed inflammation, lamellar fusion, hyperplasia, congestion and parasitic cysts, with significantly greater lesion ...

Revisiting the life cycle of Margalefidinium polykrikoides Group III. [PDF]

J Phycol
Abstract Dinoflagellates produce cysts as a strategy to withstand environmental stressors, with nutrient depletion generally considered a key trigger for cyst production. Resting cysts are thick‐walled, typically composed of one to several layers, and characterized by a prolonged dormancy period.

Acanthamoeba spp. genotypes demonstrate genotype-specific motility and encystment differences in both fed and starved environments [PDF]

Frontiers in Ophthalmology
IntroductionAcanthamoeba is a ubiquitous protozoan pathogen that can cause a severe ocular infection, Acanthamoeba keratitis. Despite its high prevalence and potential contamination of contact lenses, the natural behavior of this parasite remains poorly ...

Acanthamoeba castellanii: Non-Steroidal Anti-Inflammatory Drugs Affect Adhesion, Motility, and Encystment, Suggesting a Link with a gp63-like Protein Candidate [PDF]

Pathogens
Acanthamoeba castellanii, an opportunistic free-living amoeba, causes severe infections including Acanthamoeba keratitis. This exploratory study evaluated whether three non-steroidal anti-inflammatory drugs (NSAIDs)—acetylsalicylic acid, ibuprofen, and ...

Probing the genomic and proteomic basis of encystment in Oxytricha granulifera [PDF]

mSystems
Protozoan encystment constitutes a pivotal survival strategy against environmental stressors; however, the molecular architecture governing this transition remains enigmatic, owing to limited genomic resources and a scarcity of integrated multi-omics ...

Analysis of Encystment, Excystment, and Cyst Structure in Freshwater Eutardigrade Thulinius ruffoi (Tardigrada, Isohypsibioidea: Doryphoribiidae) [PDF]

Diversity, 2020
Encystment in tardigrades is relatively poorly understood. It is seen as an adaptive strategy evolved to withstand unfavorable environmental conditions.
