DIAGNOSTICS
LYME DISEASE (BORRELIOSIS)
by DR. A. M. REHMTULLA
VETERINARY LABORATORY SERVICES
The name "Lyme Disease" origi-
nated by way of description of an
unusual cluster of cases of rheumatoid
arthritis in children in Old Lyme
district of Connecticut around 1977.
At that time, the seasonal nature of the
disease in patients was circumstan-
tially linked to exposure to deer ticks
(Ixodes dammini).
It was not until 1982 that tiny
curved or spiral shaped bacteria (Bor-
relia burgdorferi) were identified as
the causal agents for this disease,
which these ticks transmitted.
Since then, Lyme disease or
"Lyme Borreliosis" has been recog-
nized all over the world as an im-
portant, and, in recent years, as a ra-
pidly spreading disease of both human
beings and animals. In Canada, seven
provinces have reported confirmed
cases in people, and the disease be-
came reportable in Ontario in 1988.
In this respect, Lyme disease can
be considered a zoonotic infection, in
that it is a disease that can be natural-
ly transmitted from vertebrate animals
to human beings.
In nature, the spirochete bacteria
cycle by way of the reservoir ticks,
through many wildlife species such
as small rodents (white-footed mice,
deer mice) and other small and large
wild mammals and birds, of which the
most important host is the white-tailed
dcer.
It is when domestic animals and
people become inadvertently infected
by ticks harbouring these bacteria that
Lyme disease results in these "dead-
end hosts." A well-known focus -
source of infection in Ontario is the
Long Point National Wildlife Area in
Lake Erie.
In people, early signs of Lyme
disease include headache, fever, chills,
fatigue, and a "bull's eye -like" skin
rash at the site of tick bite, followed
by numbness and arthritis in later
stages.
Symptoms in domestic animals
vary extremely, but one of the most
common presenting signs is a crip-
pling arthritis. Lyme disease in
animals is usually a sporadic occur-
rence in warm, dry, low lying areas
following the spring tick season.
Since the incubation period is pro-
longed, the classic symptoms of
arthritis may not become apparent
until much later during the fall.
This particular factor should be
borne in mind especially when dealing
with travelling animals (dogs, horses),
as symptoms may surface long after
and much distance away from the area
of initial tick exposure.
Diagnosis of Lyme disease in ani-
mals is mostly based on serology
(demonstration of antibody titres to
spirochete bacteria in blood serum).
Therefore, where Lyme disease is
suspected, veterinarians confirm the
diagnosis by submitting appropriate
specimens to diagnostic laboratories
specifically equipped to carry out
these tests.0
