Effect of Long‐Term Freezing on Indirect Fluorescent Antibody Titers for the Diagnosis of Equine Protozoal Myeloencephalitis

Journal of Veterinary Internal Medicine, Volume 39, Issue 5, September/October 2025.
ABSTRACT Background Long‐term freezing storage can alter the stability of proteins, thereby compromising accurate determination of indirect fluorescent antibody test (IFAT) titers that support the diagnosis of equine protozoal myeloencephalitis. Objective Assess the effect of long‐term storage at −80°C on IFAT against S. neurona and N.

Long‐term change and seasonal spillover risks of fatal acanthocephalan infection in southern sea otters

Ecosphere, Volume 16, Issue 8, August 2025.
Abstract Southern sea otters (Enhydra lutris nereis) face numerous risks to population recovery from infectious disease, shark attacks, and biotoxins. Recently, the most significant contributor to fatal infectious disease in sea otters has been acanthocephalan peritonitis (AP) caused by Profilicollis altmani.

Discospondylitis as a consequence of jugular vein septic thrombophlebitis in a Standardbred gelding

Equine Veterinary Education, Volume 37, Issue 8, Page e159-e165, August 2025.
Summary This report describes the identification of C7‐T1 discospondylitis on myelography and confirmed on postmortem computed tomography and necropsy in a 4‐year‐old Standardbred gelding as the consequence of jugular vein catheterisation and secondary septic thrombophlebitis. Staphylococcus aureus was isolated from both sites.

Parasite genotype is a risk factor for Sarcocystis neurona-associated mortality in southern sea otters (Enhydra lutris nereis)

International Journal for Parasitology: Parasites and Wildlife
The protozoal parasites Sarcocystis neurona and Toxoplasma gondii are important causes of mortality for threatened southern sea otters (Enhydra lutris nereis) in California. Sarcocystis neurona causes more sea otter deaths than T.

Evidence for high levels of vertical transmission in Toxoplasma gondii [PDF]

, 2009
Toxoplasma gondii is a highly ubiquitous and prevalent parasite. Despite the cat being the only definitive host, it is found in almost all geographical areas and warm blooded animals. Three routes of transmission are recognised: ingestion of oocysts shed

Genome evolution in intracellular parasites: Microsporidia and Apicomplexa

Journal of Eukaryotic Microbiology, Volume 71, Issue 5, September/October 2024.
Abstract Microsporidia and Apicomplexa are eukaryotic, single‐celled, intracellular parasites with huge public health and economic importance. Typically, these parasites are studied separately, emphasizing their uniqueness and diversity. In this review, we explore the huge amount of genomic data that has recently become available for the two groups. We
