Tentative novel lyssavirus in a bat in Finland.

A tentative novel member of the genus Lyssavirus, designated as Kotalahti bat lyssavirus, was detected in a Brandt's bat (Myotis brandtii) in Finland. Based on phylogenetic analysis, the virus differs from other known lyssaviruses, being closely related to Khujand virus, Aravan virus, Bokeloh bat lyssavirus and European bat lyssavirus 2.

Repeated dose 28-day oral toxicity study of moniliformin in rats.

Moniliformin is a Fusarium mycotoxin mainly produced by several species infecting grains in different climatic conditions. According to our previous studies, it is acutely toxic to rats, with an LD50 cut-off value of 25mg/kg b.w.

Characterization of a new epidemic necrotic pyoderma in fur animals and its association with Arcanobacterium phocae infection.

A new type of pyoderma was detected in Finnish fur animals in 2007. The disease continues to spread within and between farms, with severe and potentially fatal symptoms. It compromises animal welfare and causes considerable economic losses to farmers.

Application of OECD Guideline 423 in assessing the acute oral toxicity of moniliformin.

Moniliformin is a Fusarium mycotoxin highly prevalent in grains and grain-based products worldwide. In this study, the acute oral toxicity of moniliformin was assessed in Sprague-Dawley male rats according to OECD Guideline 423 with a single-dose exposure. Clinical observations and histopathological changes were recorded together with the excretion of moniliformin via urine and feces, utilizing a novel liquid chromatography-mass spectrometry method.

Exercise-induced changes in atrial peptides in relation to neuroendocrine responses and fluid balance in the horse.

Previous data show that, in horses, plasma atrial natriuretic peptides (ANP and NT-ANP) remain elevated for a long time after exercise. To study whether exercise-induced changes in hormonal and fluid balance explain this, we measured plasma concentrations of COOH- and NH2-terminal atrial natriuretic peptides (ANP(99-129) and NT-ANP(1-98) together with arginine vasopressin (AVP), adrenocorticotrophin (ACTH), beta-endorphin, cortisol, catecholamines, and indicators of fluid balance in six Finnhorses after a graded submaximal exercise test on a treadmill. After exercise, AVP and catecholamines diminished rapidly; atrial peptides, ACTH, beta-endorphin, and cortisol remained elevated longer.
