Now we are circling Stromboli, from the Greek strongyle for round, a perfect volcanic cone rising from the sea, most famous of the Aeolian Islands.
Finally, they may become infested with cystic tapeworms or the agamic stage of a strongyle (_Strongylus edentatus_).
For these tests, horses 'feces are collected and examined using a quantitative egg counting technique -- the number of strongyle eggs per gram is measured for each horse (see Further Reading at the end of this article for a step-by-step guide).
"Individual horses differ markedly in their susceptibility to strongyle infection, and these differences are manifested in the magnitude of fecal egg counts," said Reinemeyer.
So while a good frost will kill off countless millions of strongyle eggs in a pasture, it is providing the infective third-stage larvae with that most valuable of commodities - time
But controlling strongyle infestation is not that clear cut.
In ideal conditions, a strongyle egg can go through the three larval stages in three days.
Let's follow one of those strongyle eggs: Once produced by the female adult strongyle in the horse's gut, it has a one-way ticket out of the horse's gut, eventually ending up in a pile of dung with countless thousands of its mates.
On that basis, only the five-day course of fenbendazole will deal with migrating large strongyles and all the encysted stages of the small strongyle.
That sounds great, you think, with millions of strongyle eggs killed off when the ground turns white.
