Evaluation of real‐time polymerase chain reaction for the diagnosis of protozoal myeloencephalitis in horses using cerebrospinal fluid

Journal of Veterinary Internal Medicine, 2023
Background Equine protozoal myeloencephalitis (EPM) caused by Sarcocystis neurona remains an antemortem diagnostic challenge in some horses. Recent work suggested the use of real‐time PCR (rtPCR) on cerebrospinal fluid (CSF) as a promising diagnostic ...

Investigação de anticorpos contra Sarcocystis neurona e Sarcocystis cruzi em equinos [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2015
Sarcocystis neurona is the primary agent for Equine Protozoal Myeloencephalitis (EPM), important neurological disease characterized by behavior or muscular changes, that impairs animal performance and husbandry. Sarcocystis cruzi is a pathogen related to

Descripción de un caso de mieloencefalitis equina por protozoos (EPM) en Argentina [PDF]

Analecta Veterinaria, 2019
La mieloencefalitis equina por protozoos (EPM) es causada por Sarcocystis neurona y genera importantes pérdidas económicas. En Argentina, se han detectado anticuerpos contra este protozoo, pero no se han reportado casos clínicos. Una yegua de 12 años, de

Intracranial medulloblastoma as the cause of progressive ataxia in a 6‐month‐old draft horse cross gelding

Journal of Veterinary Internal Medicine, 2023
We describe the unique clinical presentation of a central nervous system neoplasm in a 6‐month‐old draft horse cross gelding. Based on the neurologic examination at admission, neurolocalization was most consistent with a mildly asymmetric cervical ...

Effect of refrigeration, room temperature, and processing time on serum immunofluorescent antibody titers for Sarcocystis neurona

Journal of Veterinary Internal Medicine
Background Evaluating antibody titers for Sarcocystis neurona for the diagnosis of equine protozoal myeloencephalitis from serum samples is a common practice. However, ensuring timely and proper refrigeration is not always possible.

Lack of Sarcocystis neurona Antibody Response in Virginia Opossums (Didelphis virginiana) Fed Sarcocystis neurona–Infected Muscle Tissue [PDF]

Journal of Parasitology, 2006
Serum was collected from laboratory-reared Virginia opossums (Didelphis virginiana) to determine whether experimentally infected opossums shedding Sarcocystis neurona sporocysts develop serum antibodies to S. neurona merozoite antigens. Three opossums were fed muscles from nine-banded armadillos (Dasypus novemcinctus), and 5 were fed muscles from ...

Toxoplasma ceramide synthases: Gene duplication, functional divergence, and roles in parasite fitness

The FASEB Journal, Volume 37, Issue 11, November 2023., 2023
The Toxoplasma “pseudo” ceramide synthase (TgCerS2) defines a novel apicomplexan class of these essential enzymes. Abstract Toxoplasma gondii is an obligate, intracellular apicomplexan protozoan parasite of both humans and animals that can cause fetal damage and abortion and severe disease in the immunosuppressed.

3′‐end mRNA processing within apicomplexan parasites, a patchwork of classic, and unexpected players

WIREs RNA, Volume 14, Issue 5, September/October 2023., 2023
3' cleavage and polyadenylation of pre‐mRNA is associated to the m6A epitranscriptomic mark in Apicomplexan parasites. Abstract The 3′‐end processing of mRNA is a co‐transcriptional process that leads to the formation of a poly‐adenosine tail on the mRNA and directly controls termination of the RNA polymerase II juggernaut.

Subarachnoid hemorrhage and axonal degeneration after C1‐C2 cervical centesis in 2 horses

Journal of Veterinary Internal Medicine, Volume 37, Issue 3, Page 1256-1261, May/June 2023., 2023
Abstract Ultrasound‐guided cervical centesis has gained popularity as a method for collecting cerebrospinal fluid (CSF) from standing horses. There are anecdotal reports of neck stiffness, regional swelling, sensitivity to palpation, and fever after the procedure.
