Subject: [ferrethealth] new abstract and free article with a cousin
To: fhl <ferrethealth@yahoogroups.com>
I do not know if other species of gnathostomes have gotten into mustelids, but notice that some live in North America, and some worm types are very ancient and wide spread, so that does not mean automatically that the types in other locales will also do this, nor that they might do it in domestic ferrets; however

notes:
> the endemic occurrence of members of the group has been observed principally in southern Asia, Africa, Philippines, Australia, China, and Japan. Species of the genus, either as larva or adult, parasitize a variety of hosts, induding arthropods, fishes, amphibia, reptiles, birds, and mammals. Of the latter, such carnivores as Felidae, Canidae, and Mustelidae most often have been reported infected, although infre- quent reports of infections in cattle, pigs, rodents, and man have appeared in the literature
So when you see the new article it might perhaps ask your vets if it makes sense to check relevant stomach and esophageal tumors in ferrets for such worms, yet another good reason to realize that surgery is not complete without pathology by a ferret knowledgeable pathologist being done (ditto when necropsies are done):
> 4-6 worms were grouped and embedded in each granulomatous gastric tumor
> It has been known that G. nipponicum is a common parasite found in esophageal tumors of weasels, Mustela sibirica itasi and Mustela sibirica coreana, only in Japan.

(The 1941 refers to the date of official naming of the parasite.)
> Adult gnathostomes were discovered in the stomach of the Jeju weasel, Mustela sibilica quelpartis, road-killed in Jeju-do (Province). Their morphological characters were examined to identify the species. Total 50 gnathostome adults were collected from 6 out of 10 weasels examined.
In Thailand these worms tend to be seasonal so that makes me wonder if they are picked up from soil or from dropped waste:

Of course, the prevalence of some types of foods are seasonal, and I notice this on humans with uncooked eel:

Okay, this says that they have been found in the soil contaminated by fecal waste on page 135 in the middle on the final column on that page:
