Epidemiological comments A Teckel dog born in 2006 in New Caledonia (NC) was taken for scaling on 29/11/2010 to a veterinarian, who was alerted by the dog’s chronic skin problems (since 2008) and its extreme thinness. She suggested to the owners additional tests, including a biopsy. This biopsy was performed and sent to the Laboratory LAPVSO on 03/12/2011. The results received on 12/01/2011 concluded the presence of parasitic elements suggestive of Leishmania. NC being free from this disease, further tests (serology and PCR) were asked to the Laboratory LDV34 and to the Laboratory Scanelis on 18/01/2011. Positive results to Leishmania (species non specified) were received on 27/01/2011. Additional samples were then sent to the Laboratory Vet Agro Sup for confirmation of Leishmania infantum. In the meantime, a joint investigation of veterinary and public health services of NC has been conducted among the owners and the neighborhood. From a veterinary point of view: - The Teckel, which arrived in 2007 at the owners’, lived several months in contact with two female dogs imported from Spain (via France) in February 2006. These two female dogs were euthanized in 2007: on 22/08/2007, one four years and a half Boerboel, following a suspected lymphoma; on 01/10/2007, one seven years and a half Doberman, following heart problems and kidney failure. The suspected origin of the contamination is then direct horizontal transmission (bites?) between the Teckel and the 2 ill dogs with, likely, leishmaniosis. No diagnosis of leishmaniosis had been established for the two imported animals. Compulsory post-quarantine veterinary checks had been carried out in May and December 2006 and had failed to suspect the disease. - The Teckel was euthanized on 02/02/2011. - The two animals living with the Teckel (a Beauceron dog born in April 2010 and a cat born in 2006) were examined by a veterinarian and blood samples were sent on 04/02/2011 to the Laboratory Vet Agro Sup. Negative results (PCR on both animals and serology on the dog) were received on 12/02/2011. Check-up tests will be made every three months for one year. A monthly permethrin-based external treatment is applied to the dog. - Phlebotomus species usually classified as being able to transmit leishmaniosis are not present in NC but other Phlebotomus species are present and their capability to transmit Leishmania, although not proven, cannot be scientifically excluded. - Veterinarians have been informed of this native case of leishmaniosis and have been asked to notify any suspected case to veterinary services. A protocol and an investigation sheet have been made available to them. Tests will be made in France. From a human health point of view: - All the members of the owners’ family and all people having been frequently in contact with the Teckel (neighbors) have been identified to carry out serological tests for leishmaniosis. Nine people are concerned: 8 living in NC and one having left and usually living in Belgium. The 8 people living in NC have had negative serology results, no results have been received for the person living in Belgium. - A trapping of Phlebotomus in the area in which the sick animal lives has been organized and no Phlebotomus was found. - No cases of human leishmaniosis have ever been detected in NC.
