Zoonoses, Diseases Defined And Explained
Zoonoses is the term applied to a grouping of diseases that are transferable from
canine/feline to human. Basically, these diseases fall into three groupings based on
their means of transmission. This also groups these, ideally, in the means of
treatment and control. The three groupings of diseases are as follows -diseases
spread through :1) urine or feces, 2) hair and skin contact, or 3) bites and scratches.
Zoonoses - Spread through Urine or Feces
Hookworms
Hookworms enter the German Shepherd’s body in the area that directly comes in
contact with the feces-contanimated soil. Seen more commonly in the South, these
parasites are unsuited to ideally live in human beings. Traditionally they die after
crawling several inches underneath the surface layer of the skin. Inflammation
usually occurs as a result of these parasites in humans and causes a condition called
“creeping eruption” which may last several weeks or months depending on its
severity.
Leptospirosis
German Shepherd’s may come in contact with this disease through swimming,
drinking, licking their fur, or by eating food contaminated with animal urine. Many
animals may carry this, though rats are most often the culprit.
This zoonoses symptom in humans include flu-like including chills, body aches,
vomiting, fever and headache. Sometimes kidney damage may occur or the
membranes covering the spinal cord or brain may become inflamed. This disease is
not usually fatal though it does make its host miserable for weeks at a time.
Roundworms
If these parasites are swallowed by humans they migrate into the body tissues and
may cause damage, including symptoms of fever and liver enlargement which can
last up to a year in length including symptoms of fever and liver enlargement which
can last up to a year in length.
These parasites are most commonly found in small children (2-4 yrs. of age) who
mistakenly swallow the eggs and become infected. Children playing in an area in
which an animal has defecated in the past, who do not wash their hands after
coming in contact with the eggs and inadvertently sticks their hands into their
mouth are the most common receptors of roundworm. Only rarely fatal, the disease
is traditionally mild though it may be long lasting.
Tapeworms
Tapeworms can easily be ingested by any German Shepherd who swallows a flea
carrying the infected form when biting at or chewing their coat. Children may get it
virtually the same way- minus the coat chewing.
Tapeworm infestation in humans this way is actually quite rare when compared to
infestation from eating undercooked pork or beef.
Toxoplasmosis
Rarely this may cause death in humans since most people develop a resistance to it
during normal exposure. It can cause many types of birth deformities in children
born to mothers who have been infected for the first time without having developed
an immunity before becoming pregnant. Most commonly this is “picked up” through
contact with infected cat feces or in contact with contaminated soil.
Zoonoses - Prevention of Waste Transmitted Diseases
There are a few basic precautions everyone should take to prevent transmission of
any of the above mentioned diseases - zoonoses. First, clean up all pet droppings
and wash your hands each time you any come in contact with contaminated soil. It
is extremely important to teach children these steps. Also, if your German Shepherd
has gone wading or swimming in any water which may have become contaminated
with animal urine, bathe it at once when you return home.
Zoonoses - Spread through Skin/Hair Contact
Fleas
Fleas prefer feeding on your German Shepherd though they will not turn up the
chance of of making an occasional meal on humans as well.
Ringworm
Most commonly found in children (though anyone may be infected), this disease is
caused by a skin/hair eating fungus which first appears on people as a round, red,
scaly area. It grows outward in a circular formation and is the most common fungal
disease currently reported.
Rocky Mountain Spotted Fever
Tick borne, this disease or Zoonose can cause symptoms such as fever, chills and
headache though it is not usually fatal. Symptoms may last many weeks and it can
be treated with antibiotics.
Most commonly this disease is transmitted through the bite of an infected tick. Also,
you may become infected while pulling a tick off your German Shepherd. It is best to
wear gloves when removing ticks.
Scabies
The less commonly found version of mange (as opposed to the demodetic version),
this may still cause intense itching, irritation and thickening of the skin. Animal
mange may live in human skin though it cannot reproduce there. Humans have their
own version of the scabies mite.
Zoonoses - Prevention of Skin/Hair Contact Diseases
Overall, proper nutritional care and health of your German Shepherd is the best
defense against the chance of your dog harboring any of these diseases.
Frequent grooming and herbal repellents are good choices in combating most of
these diseases or Zoonoses before they become major. Stress, roaming and contact
with other dogs are the three most common points of transmission among the
previous diseases.
Wash your hands after dog contact and minimize contact with any infected pet until
the problem is cured.
Zoonoses - Diseases Caused by Bites and Scratches
Cat Scratch Fever
Some people will develop a fever, enlarged lymph nodes and malaise near the area
of a bite or scratch from a cat a few weeks after the occurrence. Though not fatal it
can be very uncomfortable and can be followed by complications. Infected cat bites
may become infected with an entirely different bacteria though the symptoms are
similar.
Probably best, is to thoroughly wash an area bitten or scratched by a cat and to
clean it liberally on a frequent basis to prevent, hopefully, infection.
Rabies
Virtually 100% fatal once the clinical symptoms appear, this disease is carried by a
virus transmitted through the saliva of an infected biting animal. Symptoms include
frothing at the mouth, extreme behavioral/personality changes and convulsions
which usually ends in the aggressive, staggering and bleary- eyed condition.
If you happen upon an animal showing any of these disease symptoms, get away
from it as quickly as possible and call your nearest animal control unit. If by chance
you are bitten, try to follow it to where it lives (if it is a stray) so that the proper
officials may capture it for testing. If you do kill it, do not injure the head as this will
be needed for verification. Also, if you are bitten by an animal exhibiting any of the
symptoms above, thoroughly wash out the wound as quickly as possible and contact
your personal physician immediately. Overall, your chances of getting rabies are
rare though you can never be over cautious.
Zoonoses - Prevention of Bite and Scratch Transmitted Diseases
Best advice, keep your German Shepherd in tip-top physical condition through
exercise and proper nutrition to reduce its chances of picking up any diseases or
parasites from less healthy animals. Also, try to minimize your pets contact with
wild animals or sick pets.
