Despite its many delights, summer
also brings its fair share of pestilence. One, called babesiosis, has only
recently been widely recognized as a potentially serious outdoor hazard.
According to a very detailed study conducted on Block Island, R.I., it could
eventually rival Lyme disease
as the most common tick-borne ailment in the United States.
But with reasonable precautions,
neither babesiosis nor Lyme should keep you from enjoying a romp in the grass
or hike in the woods.
Babesiosis is caused by protozoans
that invade red blood cells and can cause a malarialike illness.
Babesiosis (pronounced buh-BEEZ-e-OH-sis) is named for
Dr. Victor Babes, a Romanian pathologist who in 1888 identified the disease in
cattle that had fever
and blood-tainted urine. Until the mid-20th century, the disease was known only
in wild and domestic animals, which can be infected by more than 100 different
Babesia species.
The first human case was not recognized until 1957. A
Croatian herdsman who had no spleen, an important immunological organ, died
quickly of the infection, which he most likely acquired from the animals he
tended. Twelve years later, the first case in an immunologically normal person
was identified on Nantucket Island, and for years the disease was called
Nantucket fever.
Unlike Lyme disease, which quickly leapfrogged across
the country, babesiosis is spreading slowly through the Northeast and Upper
Midwest, where it is increasingly recognized as the cause of a flulike summer
ailment. It has been said that Lyme disease moves on the wings of birds, which
some experts believe carry the bacteria causing the condition. Babesiosis,
however, moves on the backs of mice and deer. Birds do not spread it.
But like the bacteria that cause Lyme disease, Babesia
protozoans are transmitted to humans by ticks,
which acquire the infection from the white-footed mouse and white-tailed deer.
And, yes, the same tick — Ixodes scapularis, popularly called a deer tick —
transmits both Lyme disease and babesiosis in this country.
The deer tick, which starts out the size of a poppy
seed, requires a blood meal at every one of its developmental stages. With its
hind legs clutching grass or a leaf, the tick sits patiently, holding its
pincerlike front legs extended, ready to latch onto an unsuspecting mammal that
happens by.
In spring or summer, that mammal could be you. In the
fall, the adult tick feeds on white-tailed deer, which don’t get sick. This
feeding allows female ticks to produce a profusion of eggs for the next
generation.
Prevention and Treatment
As with Lyme disease, precautions to prevent the bite
of a Babesia-bearing tick include staying on cleared trails to minimize contact
with leaf litter, brush and tall grass; wearing socks with long pants tucked
into them and long-sleeved shirts (not the most pleasant approach on a steamy
summer day); and applying repellent to exposed skin and clothing. Products
containing DEET can be applied directly to the skin and sprayed on clothing;
those containing pyrethrins
should be used only on clothing and shoes.
Daily tick checks should be as routine as brushing
teeth for people in environments that could harbor ticks. Check everywhere,
using mirrors if necessary, including underarms, groin, navel, back of the
neck, behind knees, between toes, behind and in ears, and on the scalp.
If a tick is found, without delay use fine-pointed
tweezers to grasp it close to the skin and pull upward with steady, even
pressure. Do not twist or yank it. Then clean the area and your hands with
rubbing alcohol or soap and water.
People who are infected can become ill one to four
weeks after a tick bite. Common symptoms include fever, malaise,
fatigue, chills and sweats, headache,
muscle and joint
pain, loss
of appetite, cough and nausea. A blood test may reveal anemia.
Certain diagnosis comes from detecting the protozoan
in a blood
smear. Dr. Krause suggested that labs examine 300 microscopic fields before
ruling out the disease.
While the infection clears in some people without
treatment, most require a combination of antibiotics,
usually atovaquone (Mepron) and azithromycin (Zithromax), for 7 to 10 days. Dr.
Krause said even patients with mild symptoms should be treated because they may
become severely ill at a later time or spread the infection to others through
donated blood.
Also available are treatments on the
outside of the property such as tick sprays, tick tubes, and a new product
known as the tick box.
Tick sprays are generally sprayed on
the lawn and throughout the yard as well. These sprays are effective at slowing
down the spread of ticks to both our children as well as our animals.
Generally these sprays are done
every 3 to 4 weeks around the property.
Then there is tick tubes. These are
tubes that are generally known as “paper towl rolls” that are stuffed with
cotton balls that are pre-treated with permethrin. These rolls are then placed
amongs wood piles and various area around the yard where mice and other small
animals congregate. The animals then take the cotton balls as nesting back to
the wooded area and make nests. This is how we get permethrin out into the
wooded areas and this onto deer and other larger animals that carry these
ticks. Attacking the pre-mature ticks on the wooded environment is a largely
used way to control the tick, by attacking it in its infant stage.
A new process is the use of the
“tick-box.” CDC, DVBD scientists have developed and patented a
host-targeted device containing a wick system that delivers the acaricide
fipronil. These boxes lure rodents inside using non-toxic bait where they are
passively treated. A single visit to a bait box can protect small mammals from
tick and flea infestations for > 52 days. As per the following wesbsite : https://www.fbo.gov/index?s=opportunity&mode=form&id=d907e2cf0141a7c277c0e3e2acd99c00&tab=core&tabmode=list&=
Here is Long Island, deer is the
large proponent used in the spread of ticks. Attacking the problem surrounding
them in their environment is how we can control the flow of these deadly ticks
in our yards.
Here at Alternative Earthcare Tree and Lawn Systems we are
very conscious of this growing problem year after year so we constantly
investigating all alternative methods to control the tick problem that exists
on our properties as organically as possible.
