Dead Foxes, Long Grass and Tick Survey (apparently the long grass is the most important)

 



Zoe Webber and myself running the Fox Deaths Project have had to deal with the end result of babesia -dead foxes. How other wildlife is affected in the UK and particularly Bristol we have no idea.

I was not going to say anything about markers on our Fox Deaths map but Zoe picked up on it immediately. All of the foxes with babesia cut straight through the City of Bristol. We need more dead foxes to test but it is striking.

There is a belief that EMF fields can attract and provide a good habitat area for ticks. If you live in Bristol then you know almost every tall building has a radio tower on it. Also, one fox died (we lost the other one) near to the Purdown radio tower (70 metres high and built in 1970).

Based on other information about ticks I suggested to the main three Bristol naturalist groupsthat if anyone had more knowledge and experience and wanted to try a tick survey then the Purdown area would be perfect.

What I got in response was a 'joke' about "ticking" a box every time a tick was found and the "very strong" opinion that every time ticks were mentioned the reaction was to cut down high grass. Polite argument did not sway the responder.

Let me make it clear that I think we need to protect and preserve our environment (I've even been called an "environmental" and "conservation" activist now. I grew up in the UK and loved long grass as well as flower meadows. The same in Germany so I am not an "anti-long grass terrorist" of any kind.

As I pointed out; until someone conducts a survey and finds ticks you cannot put up a "tick awareness" notice as the local authorities want evidence.  So the ticks have to be looked for. Naturalists are supposed to study nature and record and report (I may be one of the last old dinosaurs with that belief it seems -its all pretty birda and butterflies now). 

There is no joke if bitten and you get Lyme disease -and walking a youngster through a meadow and finding him/her has been bitten and contracted Lymes is no joke. The finding (preliminary) that the babesia in foxes cuts through the middle of Bristol and so residential areas is important. "Live with it and keep the grass long" is not the response I expect from naturalists. Perhaps they can read the post mortem reports on the foxes?

Most people habve never heard of Lyme disease let alone babesia so why would they exercise caution -nothing around to warn them at entrances etc.

I throw my hands into the air and swear aloud rather than writing the responses I want to.

What is babesiosis?

Babesiosis is a disease caused by microscopic parasites that infect red blood cells. Many different species (types) of Babesia parasites have been found in animals, only a few of which have been found in people. Babesia microti—which usually infects white-footed mice and other small mammals—is the main species that has been found in people in the United States. Occasional cases caused by other Babesia species have been detected.

How do people get infected with Babesia?

The main way is through the bite of an infected tick.

• Babesia microti is spread by Ixodes scapularis ticks, which are commonly called blacklegged ticks or deer ticks. (Although white-tailed deer are the most important food source for the adult stage of the tick, deer are not infected with B. microti.)
• The parasite typically is spread by the young nymph stage of the tick. Nymphs are mostly found during warm months (spring and summer) in areas with woods, brush, or grass.
• Infected people might not recall a tick bite because I. scapularis nymphs are very small (about the size of a poppy seed).

Other possible ways of becoming infected with Babesia include:
• Receipt of a contaminated blood transfusion (no tests have been licensed yet for donor screening); or
• Transmission from an infected mother to her baby during pregnancy or delivery.

Where do most of the cases of babesiosis occur in the United States?

Most cases occur in the Northeast and upper Midwest, particularly in parts of New England, New York state, New Jersey, Wisconsin, and Minnesota. In the Northeast, babesiosis occurs in both inland and coastal areas, including off-shore islands, such as Nantucket and Martha’s Vineyard (Massachusetts); Block Island (Rhode Island); and Shelter Island, Fire Island, and eastern Long Island (New York state).

What are the symptoms and signs of Babesia infection?

Many people who are infected with Babesia microti feel fine and do not have any symptoms. Some people develop flu-like symptoms, such as fever, chills, sweats, headache, body aches, loss of appetite, nausea, or fatigue. Because Babesia parasites infect red blood cells, babesiosis can cause hemolytic anemia (from the destruction of red blood cells).

Babesiosis can be a severe, life-threatening disease, particularly in people who.
• Do not have a spleen;
• Have a weak immune system for other reasons (such as cancer, lymphoma, or AIDS);
• Have other serious health conditions (such as liver or kidney disease); or
• Are elderly.

How soon after the exposure do symptoms develop?

Symptoms, if any, can start within a week or so. They usually develop within a few weeks or months, sometimes longer.

What should I do if I think I might have babesiosis?

See your health care provider.

How is babesiosis diagnosed in people who have symptoms of the infection?

In symptomatic people, babesiosis usually is diagnosed by examining blood under a microscope and seeing Babesia parasites inside red blood cells. To be sure the diagnosis is correct, your health care provider might have specimens of your blood tested by a specialized reference laboratory (such as at CDC or a health department). In addition, your health care provider might decide to have your blood tested for other possible causes of your symptoms, including other tickborne infections, such as Lyme disease and anaplasmosis.

I have been diagnosed with babesiosis. Do I need to tell CDC?

No. It is not necessary for you to report your case to your health department or CDC.

Reportable conditions are diseases that physicians and/or laboratories must report to their state health department. Babesiosis is reportable in some states but not in others. If babesiosis is reportable in your state, the appropriate authority (a physician, hospital, or laboratory) will submit the necessary information to the health department.

Can babesiosis be treated?

Yes. Effective treatments are available. People who do not have symptoms or signs of babesiosis usually do not need to be treated. The first step is to make sure the diagnosis is correct.

Can babesiosis be prevented?

Yes. People can take steps to prevent babesiosis and other tickborne infections. The use of prevention measures is particularly important for people at increased risk for severe babesiosis (for example, people who do not have a spleen). If possible, areas infested with ticks should be avoided, especially during warm months. If such areas cannot be avoided, use protective measures during outdoor activities. See the Prevention and Control page for tips, such as checking yourself daily for ticks. The tiny I. scapularis ticks that spread B. microti usually must stay attached to a person for more than 36–48 hours to be able to transmit the parasite. Daily tick checks can prevent transmission of the parasite.

No vaccine is available to protect people against babesiosis.
