Lyme Disease has become a prevalent problem in the last few years. It not only affects hikers and campers, but can also affect people walking across suburban lawns or city lots. Lyme Disease is caused by a spirochete bacterium that is transmitted generally through the bite of infected ticks. Not all ticks can the spirochete, so not all bites lead to Lyme Disease.
In this area, the main culprit is the deer tick (Ixodes dammini). Ticks feed on the blood of mammals, and usually acquire the spirochete infection during its immature stages of life (larva and nymph). Deer ticks don't just live on deer. Most of their life is spent in underbrush or in the nests of rodents. The infected tick may go on to bite a human, and transmit the spirochete into the human. Cats, dogs, horses, and cows all have been known to get Lyme Disease also.
The adult deer tick is about the size of a sesame seed, smaller than other species of ticks. The body of the female is dark brown to black, with a distinctive brick red abdomen. The adult male tick is smaller than the female, and is uniformly brown to black in color.
To try and lower the human-to-tick contact, there are a few things we can do:
This is another tick-borne illness that is caused by a bacteria transmitted during the feeding process of infected ticks. In Southern New Jersey, there are reported cases every year, and the main culprit is the dog tick. Not every tick bite will result in RMSF.
