Separating Chromera velia Zoospores From Culture and Estimating Their Average Motility Speed and Lifespan [PDF]

Bio-Protocol
Chromera velia is an apicomplexan alga uniquely positioned as the closest photosynthetic relative to apicomplexan parasites (Sporozoa), which include the human pathogens that cause malaria (Plasmodium) and toxoplasmosis (Toxoplasma).

Spillover dynamics and asynchronous temporal fluctuations in host density and competence drive fungal parasite persistence in multi-host, seasonal communities. [PDF]

J Anim Ecol
In this study, the authors develop a new model to show that species contributions to parasite persistence can have strong, asynchronous temporal variability, often limiting the effectiveness of targeted seasonal parasite control. The model is broadly applicable for partitioning who, when, and what drive parasite persistence in multi‐host seasonal ...

Membrane proteome analysis identifies key components of sensing in Phytophthora parasitica zoospores [PDF]

Scientific Reports
Phytophthora plant pathogens rely on motile biflagellated zoospores to efficiently locate and colonise host tissues. While rhizospheric signals guiding zoospore movement toward roots are known, the protein composition of membranes mediating these ...

Neutrophil extracellular traps and phagocytosis in Pythium insidiosum.

PLoS ONE, 2023
Neutrophils are innate immune cells that play crucial roles in response to extracellular pathogens, including bacteria and fungi. Pythium insidiosum (P insidiosum) is a fungus-like pathogen that causes "pythiosis" in mammals.

Changes in Gene Expression in Leaves of Cacao Genotypes Resistant and Susceptible to Phytophthora palmivora Infection

Frontiers in Plant Science, 2022
Black pod rot, caused by Phytophthora palmivora, is a devastating disease of Theobroma cacao L. (cacao) leading to huge losses for farmers and limiting chocolate industry supplies. To understand resistance responses of cacao leaves to P. palmivora, Stage

Preparation of Actinoplanes missouriensis Zoospores and Assay for Their Adherence to Solid Surfaces

Bio-Protocol, 2019
Spherical zoospores of a rare actinomycete, Actinoplanes missouriensis, adhere to various hydrophobic solid surfaces by means of type IV pili. The purpose of this protocol is to provide detailed descriptions of the preparation of A.

Leucine Regulates Zoosporic Germination and Infection by Phytophthora erythroseptica

Frontiers in Microbiology, 2019
Pink rot (Phytophthora erythroseptica) of potato is a major concern in many potato production regions. The pathogen produces zoospores that serve as a primary inoculum for infection.

Inhibitory effects of macrotetrolides from Streptomyces spp. on zoosporogenesis and motility of peronosporomycete zoospores are likely linked with enhanced ATPase activity in mitochondria

Frontiers in Microbiology, 2016
The release of zoospores from sporangia and motility of the released zoospores are critical in the disease cycle of the Peronosporomycetes that cause devastating diseases in plants, fishes, animals and humans.
