Successful in vitro propagation of feline coronavirus from clinically diagnosed feline infectious peritonitis cases using Vero cells: A potential model for future research

Veterinary Record Open, Volume 13, Issue 1, June 2026.
Abstract Background Feline coronavirus (FCoV) causes inapparent to progressive fatal feline infectious peritonitis (FIP) in domestic and wild cats, which affects multiple‐organ systems. Methods We investigated three clinically sick cats using different laboratory and molecular tests to diagnose and confirm FCoV and propagate the virus in Vero cell ...

A unique dual activity amino acid hydroxylase in Toxoplasma gondii.

PLoS ONE, 2009
The genome of the protozoan parasite Toxoplasma gondii was found to contain two genes encoding tyrosine hydroxylase; that produces L-DOPA. The encoded enzymes metabolize phenylalanine as well as tyrosine with substrate preference for tyrosine.

Viral Assemblages of a Hypersaline Estuary Show Divergent Responses to Freshwater and Temperature Disturbances

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Metagenomic assessment of viromes at two sites in Laguna Madre, a hypersaline estuary, showed unique viral communities. Extreme cold temperature changes showed a greater propensity to enrich AMGs toward oxidative phosphorylation and sulfur metabolism. Extreme shifts in salinity led to homogenized viral taxonomic groups more similar to those typically ...

Infectious Diseases Management in Small‐Scale Freshwater Aquaculture in West Africa: Lessons for Low‐ and Middle‐Income Countries

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Infectious diseases are an increasing threat to food security, small‐scale livelihoods and the sustainability of aquaculture in low‐ and middle‐income countries (LMICs). In sub‐Saharan Africa, aquaculture is expanding rapidly but production systems often remain fragile.

Biogenesis of the mitochondrial DNA inheritance machinery in the mitochondrial outer membrane of Trypanosoma brucei.

PLoS Pathogens, 2017
Mitochondria cannot form de novo but require mechanisms that mediate their inheritance to daughter cells. The parasitic protozoan Trypanosoma brucei has a single mitochondrion with a single-unit genome that is physically connected across the two ...

Proteomic analysis of the ventral disc of Giardia lamblia

BMC Research Notes, 2012
Background Giardia lamblia is a multiflagellated protozoan that inhabits the small intestine of vertebrates, causing giardiasis. To colonize the small intestine, the trophozoites form of the parasite remains attached to intestinal epithelial cells by ...

Leishmania donovani infection causes distinct epigenetic DNA methylation changes in host macrophages.

PLoS Pathogens, 2014
Infection of macrophages by the intracellular protozoan Leishmania leads to down-regulation of a number of macrophage innate host defense mechanisms, thereby allowing parasite survival and replication.

A new chromosome-level genome assembly and annotation of Cryptosporidium meleagridis

Scientific Data
Cryptosporidium spp. are medically and scientifically relevant protozoan parasites that cause severe diarrheal illness in infants, immunosuppressed populations and many animals. Although most human Cryptosporidium infections are caused by C. parvum and C.

Cloning, expression, and purification of an α-carbonic anhydrase from Toxoplasma gondii to unveil its kinetic parameters and anion inhibition profile.

Journal of Enzyme Inhibition and Medicinal Chemistry
Toxoplasmosis, induced by the intracellular parasite Toxoplasma gondii, holds considerable implications for global health. While treatment options primarily focusing on folate pathway enzymes have notable limitations, current research endeavours ...
