(ˈzoʊ əˌspɔr, -ˌspoʊr)

1. an asexual spore of certain algae or fungi that moves by cilia or flagella, often capable of encysting in adverse conditions.
2. an ameboid or flagellate reproductive form that emerges from the sporocyst in certain protozoans.

Indeed, in the field and laboratory, freshwater zooplankton was found to trigger Bd infection in two amphibian species by directly consuming Bd zoospores.
Rumen fluid was also determined for direct count of protozoa and fungal zoospores using the methods described by Galyean (1989) by a haemacytometer (Boeco, Singapore) and bacteria (total viable, cellulolytic, amylolytic, and proteolytic) were measured using roll-tube technique (Hungate, 1969).
Reproduction occurs by asexual quadriflagellate zoospores or sexual biflagellate gametes (Bourrelly, 1966; Chapman, 1984; Silva, 1982; Sluiman, 1989; O'Kelly and Floyd, 1990; Thompson and Wujek, 1997).
pathogenic to mammals have been published (3,4), their taxonomic relationship to Lagenidium strains approved for biological control and the capacity of their zoospores to infect mosquitoes have yet to be investigated (5,6).
The initial infection-spreading cells of the fungus, called zoospores, swim by lashing a hair-like flagellum and don't have a cell wall.
In addition, the isolates are multiplied using their zoospores, which could be a continued source of new variability, even for originally single zoosporangium isolates.
At the same time, we also investigated the diversity of its natural predators, filter-feeding micro-crustaceans that prey on motile zoospores of the fungus.
17) In brief, zoospores were released from fertile plants and the concentration of spores adjusted to 5 x [10.
Encysted zoospores of rumen fungi produce a rhizoidal system capable of penetrating plant tissues, thereby allowing access by fungi to fermentable carbohydrates that are not accessible to other rumen micro-organisms (Bachuap, 1981).
Gentle aeration distributed the zoospores throughout the tank so they settled evenly across the V tank walls.
