First report of venereal and vertical transmission of canine leishmaniosis from naturally infected dogs in Germany

<p>Abstract</p> <p>Background</p> <p>Canine leishmaniosis (CanL) is a zoonotic disease caused by <it>Leishmania (L.) infantum</it>. It is endemic to several tropical and subtropical countries but also to the Mediterranean region. It is transmitted by phlebotomine sandflies but occasional non-vector transmissions have been reported, including vertical and horizontal transmission.</p> <p>Findings</p> <p>The authors report a case of CanL in a female boxer dog from Dusseldorf, Germany, that had never been in an endemic region. A serum sample from the bitch was tested positive for antibodies against <it>Leishmania </it>(IFAT 1:2,000, ELISA 72). The bitch had whelped three litters, and one puppy from the third litter was also found to be seropositive for <it>Leishmania </it>antibodies (IFAT 1:4,000, ELISA 78).</p> <p>Conclusions</p> <p>Up to now, despite intensive searching, the occurrence of sandflies could not be proved in the bitch's region of origin. Thus, vertical and horizontal transmission are to be discussed as possible ways of infection. This may be the first report of venereal and vertical transmission of <it>L. infantum </it>in naturally infected dogs in Germany.</p

Mapping Climate Change Vulnerabilities to Infectious Diseases in Europe

Background: The incidence, outbreak frequency, and distribution of many infectious diseases are generally expected to change as a consequence of climate change, yet there is limited regional information available to guide decision making
