Isolation of an Equine Foamy Virus and Sero-Epidemiology of the Viral Infection in Horses in Japan.

An equine foamy virus (EFV) was isolated for the first time in Japan from peripheral blood mononuclear cells of a broodmare that showed wobbler syndrome after surgery for intestinal volvulus and the isolate was designated as EFVeca_LM. Complete nucleotide sequences of EFVeca_LM were determined. Nucleotide sequence analysis of the long terminal repeat (LTR) region, and genes revealed that EFVeca_LM and the EFV reference strain had 97.

Evaluation of the PATHFAST Chemiluminescent Enzyme Immunoassay for Measuring Progesterone in Whole Blood and Serum of Mares.

Evaluation of a new chemiluminescent enzyme immunoassay, the PATHFAST assay system (PATHFAST), for measurement of circulating progesterone in mares was performed. Five mares at the mid-luteal stage were administrated a single i.m.

Histologic evaluation of the diversity of epidermal laminae in hooves of horses without clinical signs of laminitis.

Objective: To evaluate the histologic diversity of epidermal laminae in hooves from horses without clinical signs of laminitis.

Sample Population: Formalin-fixed samples of stratum internum obtained from the mid region of the dorsal aspect of the hoof wall from the forelimbs of 35Thoroughbred cadavers (including foals [n = 9], yearlings [5], 2 year olds [6], racing horses [5], and mares [10]).

Procedures: Paraffin-embedded laminar tissues were stained with H&E for the evaluation of architectural variety of primary epidermal laminae (PEL) and secondary epidermal laminae (SEL).
