In this contribution the taxonomic composition of zoosporic organisms from a stream and their abundance, frequency and diversity on cellulosic baits were analyzed, finding that in spring the greatest species richness was related to high nutrient levels whereas in winter the greatest abundance and diversity wasrelated to low water temperature, nutrient levels and well oxygenated conditions.

The present contribution is the first report of parasitosis by a chytrid fungus in wild anuran amphibians in Argentina, as well as the first case of amphibian mortality documented to date in…
Multiple barcode assessment within the Saprolegnia-Achlya clade (Saprolegniales, Oomycota, Straminipila) brings order in a neglected group of pathogens
The Saprolegnia-Achlya clade comprises species of major environmental and economic importance and their taxonomy and phylogenetic relationships remain unresolved and suffer from many inconsistencies, which is a major obstacle to the widespread application of molecular barcoding to identify pathogenic strains with quarantine implications.
High-throughput sequencing reveals diverse oomycete communities in oligotrophic peat bog micro-habitat
[Southernmost record of the fungus Leptolegnia chapmanii (Oomycetes: Saprolegniales) as a mosquito larvae pathogen (Diptera: Culicidae).].
The southernmost record and the first for the neotropical region of the fungus Leptolegnia chapmanii (Oomycetes: Saprolegniales) as a mosquito larvae pathogen is communicated in Buenos Aires, Argentina.
Saprolegnia bulbosa sp. nov. isolated from an Argentine stream: taxonomy and comparison with related species.
Taxonomical description of this new species, its comparison with related oomycetes of the genus and the nucleotide sequences of the internal transcribed region (spacers ITS1, ITS2 and the gene 5.8S) of its rRNA gene are given here.

Early breeding protects anuran eggs from Saprolegnia infection
The authors suggest that the use of nanofiltration membranes for the recovery of phosphorous with a second type of technology, called a “second-generation” technology, may be beneficial for both the human and the environment.
First report of Saprolegniosis on eggs and a juvenile of "Argentinian silverside" (Odonthestes bonariensis).
This poster presents a probabilistic simulation of the response of the immune system to the presence of carbon dioxide in the air of La Plata over a period of several years.
