Och lika frågande till varför...

Hmm, måste vara vargen.

Säkert en parasit av något slag. Hjärnmask är inte en helt omöjligt förklaring till detta.

Vet inte vad man gjort i Minnesota. Men att bi i Sverige skulle missat hjärnmask i de obduktioner som skett ser jag som högst otroligt. I så fall troligare med någon för Sverige ny parasit. Kan i och för sig vara en för sverige ny variant hjärnmask som är extra svår att hitta spår av... Vad heter den där parasiten vitsvanshjort brukar bära på här borta. Som behöver någon snäcka som mellanvärd? Kanske en variant av den?

Parelaphostrongylus tenuis

A NEW DISEASE OF MOOSE. III
A NEW BACTERIUM
IN a recent paper, the first of this series, Thomas
and Cahn' have described a new disease among the
moose (Alces americana americana) in northeastern
Minnesota and the adjacent region of Ontario, Canada.
The disease is described as appearing in the
early spring, coincident with the final metamorphosis
of the tick Dermacentor albipictus into the adult
stage, which tick heavily infests the moose of this
area. The symptoms are described as marked activity
shown by blind, aimless wandering, followed by a
paralysis of the limbs and death in a great many
cases. Ticks taken from animals dying of the disease
transmitted the disease to guinea pigs and rabbits in
the laboratory, these dying with symptoms similar tothose
exhibited by the moose. The blood picture accompanying
the disease is described and the presence
of bacteria noted. An organism was isolated which,
when inoculated into experimental animals, produced
the symptoms of the moose disease and caused
death. In a second paper, Wallace, Thomas and
Cahn2 discuss further experiments with this isolated
organism and emphasize its extreme virulence. Guinea
pigs and rabbits were killed in an hour by inoculating
the organism or a filtrate of the organism. This virulent
organism was pronounced a bacterium, and was
placed tentatively in the Klebsiella group. It is a
capsulated rod form with a tendency to assume a
coccoid shape; it grows as an excessively mucoid colony
on agar, and produces Beta hemolysis on blood
agar. Its growth is extremely rapid, covering an
agar slant in five hours, and it apparently produces
an extra-cellular toxic substance. Since this paper
was published a great deal of work has been done
upon the organism, involving its life history, pleomorphic
behavior and physiological reactions. With
much of this completed, the writers are convinced
that it is a new organism not hitherto described, and
because of the seriousness of the disease which it

causes, together with its astonishing virulence, they
believe it should be named. This organism is therefore
designated as Klebsiella paralytica, because of
the paralysis it causes. A detailed report, covering
all experimental and cultural work to date, is about
to go to press.

A NEW DISEASE OF MOOSE. III

A NEW BACTERIUM

IN a recent paper, 

Jag vet inte om det behövs, men jag tycker att sammanhanget blir begripligare om man påpekar att det "recent" i det här fallet är för 80 år sen.

Jag tror att Nikee bara ville visa att den parasiten jag for efter är en variant på hjärnmask och tog första bästa länk han hittade...

Nikee

Jag har fortfarande svårt att tro att det är någon tidigare välkänd parasit. Tror mer på ny variant eller virus.
