Saksalaisista hyttysistä löytyi borreliaa...

Occurrence of Borrelia burgdorferi s.l. in different genera of mosquitoes (Culicidae) in Central Europe.

"Lyme disease or Lyme borreliosis is a vector-borne infectious disease caused by spirochetes of the Borrelia burgdorferi sensu lato complex. Some stages of the borrelial transmission cycle in ticks (transstadial, feeding and co-feeding) can potentially occur also in insects, particularly in mosquitoes. In the present study, adult as well as larval mosquitoes were collected at 42 different geographical locations throughout Germany. This is the first study, in which German mosquitoes were analyzed for the presence of Borrelia spp. Targeting two specific borrelial genes, flaB and ospA encoding for the subunit B of flagellin and the outer surface protein A, the results show that DNA of Borrelia afzelii, Borrelia bavariensis and Borrelia garinii could be detected in ten Culicidae species comprising four distinct genera (Aedes, Culiseta, Culex, and Ochlerotatus). Positive samples also include adult specimens raised in the laboratory from wild-caught larvae indicating that transstadial and/or transovarial transmission might occur within a given mosquito population"

Suomalaisista puutiaisista on löytynyt jo useita taudinaiheuttajia...silti puhutaan vain borreliasta ja TBE:stä.

B. afzelii
B. burgdorferi ss
B. garinii
B. valaisina
B. miyamotoi
B. finlandensis (amerikkalainen tutkimus v. 2011)
Rickettsia spp.
Klamydian kaltaisia organismeja (Chlamydia-like organisms)
TBE-virus
Francisella tularensis

https://www.utu.fi/fi/yksikot/puutiaise ... eeri-.aspx
"​Saaristomerellä sijaitsevalla Seilin saarella toteutetussa tutkimuksessa puutiaisista löydettiin Borrelia afzelii, B. burgdorferi, B. garinii, B. valaisiana ja B. miyamotoi -bakteerilajit. Neljän ensiksi mainitun tiedetään aiheuttavan Lymen borrelioosia, mutta toisintokuumeborrelioiden ryhmään kuuluva B. miyamotoi voi aiheuttaa infektion, johon liittyy influenssan kaltainen korkeakuumeinen yleisinfektio ja keskushermoston tulehdus."

"– Borrelia-bakteerien kirjo on moninainen. Eri bakteerikantojen yhteys Lymen borrelioosin eri oireisiin ja ilmenemismuotoihin on huonosti tunnettua, Hytönen sanoo."

"Kotimaisten punkkien on havaittu uusimmissa tutkimuksissa levittävän tunnettujen borrelia-bakteerien ja aivotulehdusta aiheuttavan viruksen lisäksi myös muita taudinaiheuttajia. Turun yliopiston tutkijat ovat löytäneet suomalaisista punkeista myös anaplasma- ja riketsia-bakteereita."

"Abstract
Ticks carry several human pathogenic microbes including Borreliae and Flavivirus causing tick-born encephalitis. Ticks can also carry DNA of Chlamydia-like organisms (CLOs). The purpose of this study was to investigate the occurrence of CLOs in ticks and skin biopsies taken from individuals with suspected tick bite. DNA from CLOs was detected by pan-Chlamydiales-PCR in 40% of adult ticks from southwestern Finland. The estimated minimal infection rate for nymphs and larvae (studied in pools) was 6% and 2%, respectively. For the first time, we show CLO DNA also in human skin as 68% of all skin biopsies studied contained CLO DNA as determined through pan-Chlamydiales-PCR. Sequence analyses based on the 16S rRNA gene fragment indicated that the sequences detected in ticks were heterogeneous, representing various CLO families; whereas the majority of the sequences from human skin remained “unclassified Chlamydiales” and might represent a new family-level lineage. CLO sequences detected in four skin biopsies were most closely related to “uncultured Chlamydial bacterium clones from Ixodes ricinus ticks” and two of them were very similar to CLO sequences from Finnish ticks. These results suggest that CLO DNA is present in human skin; ticks carry CLOs and could potentially transmit CLOs to humans."

"Human Lyme disease is caused by a number of related Borrelia burgdorferi sensu lato species. We report here the complete genome sequence of Borrelia sp. isolate SV1 from Finland. This isolate is to date the closest known relative of B. burgdorferi sensu stricto, but it is sufficiently genetically distinct from that species that it and its close relatives warrant its candidacy for new-species status. We suggest that this isolate should be named “Borrelia finlandensis.”"

"Suomessa jänisruttotartuntaa välittäviä eläimiä ovat hyttyset, myyrät, hiiret, jänikset, piisamit, paarmat, mäkärät ja puutiaiset. "

"Bartonella-infektion mahdollisuus on olemassa, koska pohjoismaisistakin puutiaisista tätä on löydetty."
