Ann Agric Environ Med. 2006 ;13 (2):345-8 17199258 Isolation of Borrelia afzelii from overwintering Culex pipiens biotype molestus mosquitoes. [My paper] Alena Zakovska , Lucie Capkova , Omar Sery , Jiri Halouzka , Milos Dendis
A total of 662 samples (winter period: 469; summer period: 193 specimens) of female mosquitoes of the genus Culex, Aedes and Anopheles were collected during the period March 2000-April 2001 from the locality of Vysoke Myto (Eastern Bohemia, Czech Republic). They were examined by dark field microscopy for the presence of spirochetes. The motile spirochetes were observed in 4.2 % of all species of investigated mosquitoes. One spirochetal strain out of the 8 isolation attempts (BRZ14) was obtained (cultivation rate was 12.5 %) and the spirochetal strain was then successfully cultivated and identified using PCR for the presence of Borrelia burgdorferi s.l., and subsequently with the RFLP as genomospecies Borrelia afzelii. This strain was derived from overwintering Culex (Culex) pipiens biotype molestus female mosquitoe. This is apparently one of the sporadic cases of the occurrence of pathogenic borreliae in haematophagous arthropods, other than Ixodes ricinus complex ticks.

Dr. K was telling us about that all along. He said, that 22% of all mosquitos carry spirochetes. Just do the math: 5 bites during a lifetime = 100% chance of spirochetal infection. Doesn't mean, you have to nesssecarily come down with Lyme, but the chances are pretty high. Also be very aware of biting flies and chiggers.

Has this level of 22% been published somewhere, or is it anecdotal? Anne

But the ISDA says only ticks? I watched Alan Steere at the July 30th hearing definitely tell the world only ticks carry and transmit Bb.

Mites are capable of transmitting borrelia to mice
[An experimental study of the capacity of the rat mite Ornithonyssus bacoti (Hirst, 1913) to ingest, maintain and transmit Borrelia] [Article in Russian]
For the first time a possibility of the gamasina mites' O. bacoti participation in Lyme disease spirochetes' circulation has been demonstrated. It has been experimentally shown that Borrelia burgdorferi s.l. are received by O. bacoti, survive in them for at least 21 days and are transmitted to white mice through mites' bites. Mice's infestation has occurred in 23% of cases. It is suggested that other bloodsucking gamasina mites inhabiting the Lyme borreliosis reservoir rodents nests may be capable of participating in borrelia circulation in the Lyme disease endemic areas.
from 1988 Ticks and biting insects infected with the etiologic agent of Lyme disease, Borrelia burgdorferi. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC266646/?tool=pubmed "Groups of 113 field-collected mosquitoes of Aedes canadensis and 43 Aedes stimulans were placed in cages with uninfected Syrian hamsters. Of these, 11 females of both species contained B. burgdorferi and had fed fully or partially from the hamsters. No spirochetes were isolated from the hamsters, but antibodies were produced in one test animal."
More to come...

Don't you think that (at the very least) if a mosquito bit someone or some animal that had Lyme, then bit YOU .. that you could get infected?

The global distribution of Lyme disease. Schmid GP.
Erythema chronicum migrans (ECM), the skin lesion characteristic of Lyme disease, was first described in Sweden in 1909; subsequently, cases of ECM have been reported from at least 19 countries on three continents.
In Europe cases have occurred within the range of Ixodes ricinus ticks, the recognized vector of ECM in Europe, although one case outside this range has been ascribed to mosquito bites. In 1970 the first case of ECM acquired in the United States was reported, and in 1977, the full symptom complex now called Lyme disease was described.
In the United States three geographic areas endemic for Lyme disease are recognized: the coastal areas of the Northeast; Minnesota and Wisconsin in the Midwest; and parts of California, Oregon, and western Nevada in the West. These areas correspond to the recognized distribution of Ixodes dammini in the Northeast and Midwest and Ixodes pacificus in the West.
Isolated cases of illness compatible with Lyme disease have, however, been reported from other parts of the United States; this suggests that cases may be more widely distributed than is currently recognized and that other vectors may be involved. Supporting this suggestion is the description in 1982 of Lyme disease in Australia, where none of the currently recognized vectors are known to exist, and the report in 1984 that Ambylomma americanum ticks can harbor the spirochete that causes Lyme disease.
The recognition of cases acquired in widely separated parts of the world involving multiple vectors suggests that cases may in the future be diagnosed in additional areas.

Also in the Documentary UOS, Shapiro said, you can only get LD one way.....from the bite of the Xodes tick. Another stupid nerd!

I think the transfer of borrelia from mites to white mice proves that borrelia can be transmitted by something other than a tick. If it can be transmitted to a mouse, it wouldn't be a stretch to think it can be transferred to other mammals, including humans.

No doubt. We are positive infection was transmitted to us by mosquitoes.

I've known for years there had to be numerous blood sucking vectors out there spreading lyme & co at numbers believed to be 250,000 a year.
Ticks alone just didn't make sense to me. That's why I use the term blood vectors and vector borne illnesses, because it states the big picture.
It's not just ticks!!!!!
