What type of tick lyme disease
In most cases, the tick must be attached for 36 to 48 hours or more before the Lyme disease bacterium can be transmitted. Most humans are infected through the bites of immature ticks called nymphs. Nymphs are tiny less than 2 mm and difficult to see; they feed during the spring and summer months. Adult ticks can also transmit Lyme disease bacteria, but they are much larger and are more likely to be discovered and removed before they have had time to transmit the bacteria.
Adult Ixodes ticks are most active during the cooler months of the year. While questing, ticks hold onto leaves and grass by their lower legs. They hold their upper pair of legs outstretched, waiting to climb onto a passing host.
When a host brushes the spot where a tick is waiting, it quickly climbs aboard. It then finds a suitable place to bite its host. The lifecycle of blacklegged ticks Ixodes scapularis and Ixodes pacificus generally lasts two years. During this time, they go through four life stages: egg, six-legged larva, eight-legged nymph, and adult. After the eggs hatch, the ticks must have a blood meal at every stage to survive.
Blacklegged ticks can feed from mammals, birds, reptiles, and amphibians. The ticks need to have a new host at each stage of their life, as shown below:.

Nymphal ticks cause most cases of Lyme disease. Adult ticks can also infect humans, but are easier to spot and remove. Not all ticks are infected. Because tick studies have only been done in a relatively few places, in most of the US, tick infection rates are unknown.
Even in places where ticks generally do not carry Lyme, there may be hotspots of infection depending on local conditions. The tick infection rate may also change from year to year, even in one location. To get a better idea of which tick-borne diseases have been found in your area, check this site.
