This MYGERMANSHEPHERD PERIODICAL is about TICKS. Almost as much as the last Periodical - the last Flea Periodical was a BOOK, I won't do that again, I haven't seen questions and feedback yet, seems like no one survived reading that much!??
However, this Periodical I made region-specific - as much as I could, a LOT of work again!
I left out the Latin names of the ticks, as no one needs them here. To make it as simple for you as the last Periodical, just click where you are based to see the locally prevalentticks and tick diseases. You will then be led through to all important points thereafter:
About 90 tick species are known to be endemic in continental U.S., but just about 10% of these (~9) bite dogs and people, and are known vectors to dangerous pathogens that can affect animal and human health. Obviously, here we will only look at those 9. However, as you will see in a moment, just these few tick species alone are more than you'd like to host.
Like everywhere else, most american ticks (about 80) are hard ticks (Ixodidae), only about 10 american ticks are soft ticks (Argasidae). What this means for you is explained further below under Ticks for everyone.
Where are they?
One american tick, the Brown Dog Tick, enjoys to be hosted by farmers and families all across the United States, including Hawaii, except in Alaska. - There are no common infectious ticks in Alaska, however the endemic tick that goes by the name Ixodes angustus has experimentally proven that it has vector competency to transmit lyme disease (later under tick diseases).
The geographical distribution of the 'hot spots' of the Brown Dog Tick, Rocky Mountain Wood Tick and Gulf Coast Tick I was able to combine in the single map shown below (tick-individual maps came from CDC):
Note that ticks know no political systems, state borders, north-south or east-west differences (or religions). Ticks feel welcomed by any host anywhere who lives inmidst suitable flora and fauna, and who provides them with a blood meal of their choice.
The American Dog Tick enjoys the flora and fauna and diet all across the eastern half of the United States plus California. The Lone Star Tick is keeping up pretty well, and is already endemic all over the mid and south east of the U.S.:
Note that the American Dog Tick and the Lone Star Tick are active host-seekers - these ticks will 'go the extra mile' to pay a tick-friendly host a surprise visit. Particularly the American Dog Tick, when it senses a regular source of carbon dioxide or carbon monoxide (like from a human dwelling), this tick species may literally crawl towards the house and even crawl up the outside walls towards the window screens and doors (as reported in one case of professional tick spotters).
The Lone Star Tick is particularly aggressive. Even its larvae will bite humans, whereas none of the other tick larvae is known to do that.
The Blacklegged Tick (or Deer Tick) all over east and mid-south U.S., and the Western Blacklegged Tick along the Pacific coast have fallen behind (or woke up late), neither of these have yet conquered central U.S. (see map below). This doesn't mean they can't be found there anywhere (a few adventurous representatives have been seen more or less everywhere), it just means their 'middle class' isn't (yet) expanding there. For more, see later Why ticks migrate.
Also note that, without a host, the blacklegged tick or deer tick is a passive host-seeker - these ticks rarely move horizontally more than a few meters. This doesn't mean though that these ticks aren't migrating: Over years and decades they are incrementally drawn towards a host-source, like say the shady edge of a pasture or a regularly used deer trail or parkland path.
However, the Western Blacklegged Tick or Pacific Coast Tick spreads more and more along the ... well, Pacific coast! (the name-giving researchers make it too easy for us ) And the Latino relatives of all ticks that go by the name of Cayenne Tick (mnemonic: Porsche Cayenne; now I made it easy for you ) are totally ignoring the human-made Mexican border and are spreading into mid-south U.S.
Before we get to tick diseases, let's briefly look whether Canadian ticks offer any specifics. Note that Canadian ticks are relevant to Americans too (and vice versa!) because...? Yes, ticks know no borders! - Not even borders that dogs know, if and when we make use of the respective dog training tool (more detail in the Dog Training Toolkit).
Ticks common in Canada:
Blacklegged Tick or Deer Tick
Western Blacklegged Tick or Pacific Coast Tick
Ixodes Angustus (no common name)
Lone Star Tick
American Dog Tick
Brown Dog Tick
and Rocky Mountain Wood Tick
Oh, all the same? Yes, you noticed that Canada hosts the same tick species as the U.S., except for the Gulf Coast Tick and the Cayenne Tick (yet).
For the Western Blacklegged Tick or Pacific Coast Tick and the American Dog Tick I could find geo indications of where these ticks are most prevalent:
For a brief description of the subsequent tick diseases see Ticks for everyone, because disease descriptions are of global relevance.
Which tick diseases are endemic in North America?
Geographical distribution of the most prevalent tick-borne infectious diseases of humans with animal contact, primarily dogs (from Gideon database):
Anaplasmosis: tick vector-borne bacterial infection. Incubation period 7-21 days.
Babesiosis: tick vector-borne infection. Incubation period 7-63 days.
Bacillary angiomatosis: cat flea (but also tick) vector-borne bacterial infection. Incubation period 16-22 days.
Bartonellosis: tick and cat vector-borne bacterial infection. Incubation period 3-14 days.
Bunyaviridae infections: tick, midge, and mosquito vector-borne viral infection. Incubation period 10-15 days.
Ehrlichiosis: tick vector-borne bacterial infection. Incubation period 7-21 days.
Lyme disease: tick vector-borne bacterial infection. Incubation period 7-14 days.
Relapsing fever: tick and louse vector-borne bacterial infection. Incubation period 7-8 days.
