New model helps in fight against deadly parasitic disease

Cole Porter romanticized the phrase in his 1936 song, but the probable origin of having someone—or something—under one's skin is much less pleasant to consider. An early usage of the phrase by author Bayard Taylor in 1864 illustrates: "The idea was like a tropical sand-flea. It had got under my skin, and the attempt to dislodge it opened the germs of hundreds of others." Today, in some water bodies, the possibility of going in for a swim and coming out with a disease-causing parasite lodged under the skin remains all too real.

Seasonal effects: 'Winter foals' are smaller than foals born in summer

Season determines behaviour, metabolism and reproductive activity in many animal species, including horses. Even in domesticated horse breeds metabolic activity is reduced in winter. Although these effects are known since a few years, effects on pregnant mares and their foals have not been investigated so far. Researchers from Vetmeduni Vienna have now demonstrated that seasonal changes during winter have a strong influence on pregnancy and foetal development. Foals born early in the year are smaller than herd mates born at a later time and these differences persist to at least 12 weeks after birth. The study has recently been published in Theriogenology.
