Jansen A, Luge E, Guerra B, Wittschen P, Gruber AD, Loddenkemper C, Schneider T, Lierz M, Ehlert D, Appel B, Stark K, Nöckler K (2007): Leptospirosis in urbanized wild boars, Berlin, Germany
Emerg. Infect. Dis. 13 (5): 739-742.

We found antibodies to leptospires in 25 (18%) of 141 wild boars from Berlin (95% confidence interval 12–25). Seropositivity was associated with chronic interstitial nephritis (odds ratio 10.5; p = 0.01), and leptospires were detected in kidney tissues. Wild boars represent a potential source for human leptospirosis in urban environments.
