Melting pot of tick-borne pathogens found in European hedgehogs

The study entitled “Melting pot of tick-borne zoonoses: the European hedgehog contributes to the
maintenance of various tick-borne diseases in natural cycles urban and suburban areas,” investigates the
extent to which hedgehogs contribute to the enzootic cycle of tick-borne pathogens.

Study finds 39% of ticks infected directly from the European hedgehogs carried more than one pathogen.
European hedgehogs are urban dwellers and legally protected in Belgium, making them easy to study.
Engorged ticks were collected from hedgehogs in urban and suburban areas via rehabilitating centers in
Belgium. The number of ticks per hedgehog ranged from 1 to 167.

The authors found that 71% of the ticks were infected with at least one pathogen which could include B.
miyamotoi, A. phagocytophilum, R. helvetica and B. burgdorferi genospecies (B. afzelii, B. bavariensis
and B. spielmanii). “An infection with B. miyamotoi occurred in 20 ticks from five hedgehogs.” according
to Jahfari from the Centre for Infectious Disease Control, National Institute of Public Health and
Environment (RIVM), Netherlands.
The ticks were not screened for Babesia microti, which has been shown in another study to infect up to
40% of patients with Lyme disease. [2] Learn more about the diagnosis and treatment of Babesia.
Many of the ticks were infected with more than one organism. "Thirty-nine percent of the ticks were
infected with more than one pathogen of another genus" according to Jahfari.

The European hedgehogs were capable of infecting the ticks. The infection rate was higher for Ixodes
ricinus larvae and nymphs removed from the European hedgehogs than for questing I. ricinus nymphs
and adults removed from the ground.
Hedgehogs can potentially transmit tick-borne diseases in urban and suburban regions. The authors
conclude, “European hedgehogs seem to contribute to the spread and transmission of tick-borne
pathogens in urban areas" and the “relatively high prevalence of B. bavariensis, B. spielmanii, B. afzelii,
A. phagocytophilum, and R. Helvetica in engorged ticks suggests that hedgehogs contribute to their
enzootic cycles in (sub) urban areas.”

“Hedgehogs reach up to nine times higher densities in urban areas with parks and garden, than in rural
areas, with lowest densities in forests and open grassland fields and agricultural land without cover such
as shrubs or dead wood," the authors state. "Humans are likely to encounter ticks infected with one or
several of these pathogens while gardening or recreating in parks.”

Jahfari and colleagues' findings that European hedgehogs collected in the Netherlands harbor a “melting
pot” of tick-borne zoonoses reminds doctors of the difficulties in diagnosing and identifying best
treatment options for infected patients.

Even over die Babesia.

Die komt hier in Nederland ook voor.

http://www.nature.com/nature/journal/v2 ... 215a0.html

Babesia wordt beschreven in 1911 onder het vee van Groot Brittannië
Men kon het toen bijna niet geloven en men hield de optie open dat babesia misschien
geïmporteerd was vanuit Zuid Afrika.
Maar hun onderzoek gaf toch de mogelijkheid aan dat Babesia gewoon nog aanwezig was in Groot B.
Dat werd bevestigd door Nederlandse literatuur van:

Bool, P. H., Goedbloed, E., en Keidel, H. J. W., Tijdschr. Diergeneesk., 86, 28 (1961).
En:
Zwart, D., Van den Ende, M. C., Kouwenhoven, B., en Buys, J., Tijdschr. Diergeneesk., 93, 126 (1968).


Dan komt Babesia al heel lang voor in Engeland en ook in Nederland.
En ook is het ondertussen bekend dat het wordt overgebracht door teken:

En, dat mensen er ook ziek van kunnen worden:
