Freshwater Mussel Anodonta cygnea Reduces Concentration, Germination Rate and Infectivity of Pathogenic Oomycete Saprolegnia spp. Spores

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT Saprolegniosis, also known as water mould, is a lethal disease caused by Saprolegnia oomycetes that threatens freshwater animals including fish, amphibians, and crustaceans, as well as aquaculture. It causes biodiversity loss and population declines, including those of endangered fishes.

Effects of biosecure macroalgae in formulated feeds on the gut bacterial microbiome of abalone Haliotis midae

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Dietary macroalgae are known to contribute directly and indirectly to the gut microflora of abalone. However, certain farms require macroalgae to be made biosecure to eliminate microbiota and reduce their risk of acting as a vector for potential disease before being included as a dietary ingredient in aquafeeds.

Mechanism of the anti-tumour effect of glucans and fructosans: a comparison with C. parvum [PDF]

British Journal of Cancer, 1977
The anti-tumour activity induced by glucans (lentinan, yeast cell walls, pseudonigeran, dextran, DEAE-dextran and dextran sulphate) and fructosans (levan and carboxymethyl-levan) was compared with the activity of C. parvum. The following effects on tumour systems in CBA mice were assayed: (a) adjuvant activity on the immune response against tumour ...

MiR-199a-3p regulates HCT-8 cell autophagy and apoptosis in response to Cryptosporidium parvum infection by targeting MTOR

Communications Biology
The microRNAs (miRNAs) of their hosts play an important role in regulating both the innate and adaptive immune responses to Cryptosporidium parvum infection. The mechanisms of autophagy and apoptosis are important components of the defense system against

Endophytic and ectomycorrhizal, an overlooked dual ecological niche? Insights from natural environments and Russula species

New Phytologist, Volume 250, Issue 6, Page 3946-3960, June 2026.
Summary Ectomycorrhizal fungi (EcMF) are key components of temperate ecosystems, and recent studies suggest that they can also inhabit non‐EcM plant roots as endophytes. We aimed to (1) provide new evidence of EcMF colonization of non‐EcM hosts, (2) offer direct microscopic confirmation of such endophytism and (3) assess factors influencing ...

Biological and genomic resources for the cosmopolitan phytoplankton Bathycoccus: insights into genetic diversity and function of outlier chromosomes

The Plant Journal, Volume 126, Issue 5, June 2026.
SUMMARY Population‐scale genome sequencing has become essential for exploring genetic diversity and adaptation, particularly in land plants. In contrast, eukaryotic phytoplankton resources remain limited to model reference genomes or community‐level metagenomics, leaving a gap in understanding intraspecific variation and evolutionary processes.

Genetic diversity within Cryptosporidium parvum and related Cryptosporidium species.

, 1999
To assess the genetic diversity in Cryptosporidium parvum, we have sequenced the small subunit (SSU) rRNA gene of seven Cryptosporidium spp., various isolates of C.

Zoonotic Transmission Assessment of Cryptosporidium spp. in Close Human–Pet Environments in Yunnan Province, China

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study revealed Cryptosporidium infection rates of 11.1% in dogs and 10.4% in cats in human–pet environments in Yunnan, China. Molecular evidence documents one case of pet‐to‐human transmission involving an immunocompromised elderly owner, suggesting vulnerable individuals face higher infection risks despite minimal transmission to immunocompetent ...

The 100 Faces of Cryptosporidium parvum

, 2012
Cryptosporidium parvum is a protozoan enteric parasite of humans and livestock. C. parvum infection mainly affects the ileum, where it has the potential to cause severe enteric disease. Drugs for the treatment of cryptosporidiosis are still not available

Characterization of INS-15, A Metalloprotease Potentially Involved in the Invasion of Cryptosporidium parvum

Microorganisms, 2019
Cryptosporidium parvum is a protozoan parasite that can cause moderate-to-severe diarrhea. Insulinase-like proteases (INS) are one of the largest protein families within the small proteome of the pathogen. However, their roles in C. parvum biology remain
