Leishmaniose-Infektionen in Deutschland

– Gefahr geht nicht nur von Sandmücken aus –

Die Zahl Leishmaniose-infizierter Hund esteigt in Deutschland durch den Import von Hunden aus Endemiegebieten und reisebegleitende Hunde immer mehr an. Lange Zeit ging man jedoch davon aus, dass für Hunde in Deutschland keine Ansteckungsgefahr besteht. Doch das stimmt wohl nicht. Die Tierärztliche Umschau sprach mit dem Parasitologen Dr. Torsten Naucke von der Universität Hohenheim und Reisekrankheitenexperte vom Veterinärlabor Laboklin, Bad Kissingen, über die neuesten Erkenntnisse.

Therapiemöglichkeiten der kaninen Herzwurmerkrankung

Die Liste praxisrelevanter, durch Vektoren übertragener Infektionskrankheiten in Deutschland wächst stetig. An Bedeutung gewinnt dabei auch immer mehr die Herzwurmerkrankung (kardiovaskuläre Dirofilariose) des Hundes. Dabei handelt es sich um eine schwere und potenziell tödliche Erkrankung, die durch Fadenwürmer der Gattung Dirofilaria immitis ausgelöst wird. Die Krankheit kommt zwar hauptsächlich beim Hund vor, Endwirte sind aber auch Katzen und Füchse. Gelegentlich können Herzwürmer auch auf Menschen übertragen werden.

First report of transmission of canine leishmaniosis through bite wounds from a naturally infected dog in Germany

Abstract

Background: Canine leishmaniosis (CanL) is an important zoonosis caused by Leishmania (L.) infantum. Transmission of L. infantum to dogs (and humans) is mainly through the bite of infected sandflies, but the parasite can also be transmitted vertically, venereally and through blood transfusions of infected donors. Additionally, the direct dog-to-dog transmission through bites or wounds is suspected.

Evaluation of a rapid device for serological in-clinic diagnosis of canine angiostrongylosis

Abstract

Background: Angiostrongylus vasorum is a potentially fatal canine nematode. Due to the high variability of clinical signs and the often chronic and subtle course of the infections, the diagnosis is particularly challenging. A rapid in-clinic assay (Angio Detect™ Test, IDEXX Laboratories, Westbrook, Maine, USA) for the serological detection of circulating antigen and intended for routine in-clinic diagnosis has been evaluated.

Nicht-vektorassoziierte Übertragung der caninen Leishmaniose in Deutschland

Zusammenfassung

In Deutschland leben mittlerweile rund 20.000 mit Leishmaniose infizierte Hunde. Vor allem der Import von Tieren aus endemischen Gebieten und reisebegleitende Hunde führen zum Anstieg der Leishmaniose-Fälle. Neben der epidemiologisch bedeutsamsten Übertragung des Erregers durch Sandmücken, werden zunehmend auch eine venerische Übertragung durch erregerhaltige Samenflüssigkeit und/oder eine trans-/diaplazentare Übertragung der Leishmanien von infizierten Hündinnen auf ihre Welpen diskutiert. In diesem Artikel werden anhand eines aktuellen Fallberichts über eine an Leishmaniose erkrankte Boxer-Hündin und ihre Nachkommen die Auswirkungen einer nicht-vektorassoziierten Erregerübertragung in Deutschland erörtert.

Emergence of sandflies (Phlebotominae) in Austria, a Central European country

Abstract

The possible existence of autochthonous sandfly populations in Central Europe north of the Alps has long been excluded. However, in the past years, sandflies have been documented in Germany, Belgium, and recently, also in Austria, close to the Slovenian border. Moreover, autochthonous human Leishmania and Phlebovirus infections have been reported in Central Europe, particularly in Germany.

Morphometric analyses of canine blood microfilariae isolated by the Knott’s test enables Dirofilaria immitis and D. repens species-specific and Acanthocheilonema (syn. Dipetalonema) genus-specific diagnosis

Background

In Europe the most common canine filarial species presenting blood circulating microfilariae (mf) are Dirofilaria immitis, D. repens, Acanthocheilonema (syn. Dipetalonema) dracunculoides and A. (syn. Dip.) reconditum [1]. They are transmitted by haematophagous arthropods: Dirofilaria spp. by mosquitoes, A. reconditum by fleas and lice and A. dracunculoides by ticks. D. immitis, the aetiological agent of canine heartworm disease, is the most pathogenic species for dogs: adults live in the right side of the heart and in the pulmonary artery, causing pulmonary hypertension and congestive heart failure. Adults of D. repens live in the subcutaneous tissue, occasionally causing dermatological problems [2].

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

Findings

Canine leishmaniosis (CanL) caused by Leishmania (Leishmania) infantum (or its New World synonym Leishmania (L.) chagasi) is a zoonotic disease of major public health and veterinary importance with a wide geographical distribution. It is endemic in Mediterranean countries and in regions of Africa, Asia, South and Central America [1]. But CanL is also an important concern in non-endemic regions. In Germany, increasing numbers of dogs are becoming infected by L. infantum as a result of travelling to Mediterranean countries, or being imported from these regions. It is estimated that there are 20,000 infected dogs in Germany [2]. Canine infection is associated with variable clinical manifestations, ranging from unapparent subclinical infections to fatal visceralizing disease.

Vector-Borne Diseases - constant challenge for practicing veterinarians: recommendations from the CVBD World Forum

Titel: Vector-Borne Diseases - constant challenge for practicing veterinarians: recommendations from the CVBD World Forum
Inhalt: The human-animal bond has been a fundamental feature of mankind's history for millennia. The first, and strongest of these, man's relationship with the dog, is believed to pre-date even agriculture, going back as far as 30,000 years. It remains at least as powerful today. Fed by the changing nature of the interactions between people and their dogs worldwide and the increasing tendency towards close domesticity, the health of dogs has never played a more important role in family life. Thanks to developments in scientific understanding and diagnostic techniques, as well as changing priorities of pet owners, veterinarians are now able, and indeed expected, to play a fundamental role in the prevention and treatment of canine disease, including canine vector-borne diseases (CVBDs). The CVBDs represent a varied and complex group of diseases, including anaplasmosis, babesiosis, bartonellosis, borreliosis, dirofilariosis, ehrlichiosis, leishmaniosis, rickettsiosis and thelaziosis, with new syndromes being uncovered every year.

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

Titel: First report of venereal and vertical transmission of canine leishmaniosis from naturally infected dogs in Germany
Inhalt: Canine leishmaniosis (CanL) is a zoonotic disease caused by Leishmania (L.) infantum. 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. Findings The authors report a case of CanL in a female boxer dog from Dusseldorf, Germany, that had never been in an endemic region.

Combining climatic projections and dispersal ability: a method for estimating the responses of sandfly vector species to climate change

Titel: Combining climatic projections and dispersal ability: a method for estimating the responses of sandfly vector species to climate change.
Inhalt: In the Old World, sandfly species of the genus Phlebotomus are known vectors of Leishmania, Bartonella and several viruses. Recent sandfly catches and autochthonous cases of leishmaniasis hint on spreading tendencies of the vectors towards Central Europe. However, studies addressing potential future distribution of sandflies in the light of a changing European climate are missing.

Dogs as carriers of canine vector-borne pathogens

Titel: Imported and travelling dogs as carriers of canine vector-borne pathogens in Germany
Inhalt: With the import of pets and pets taken abroad, arthropod-borne diseases have increased in frequency in German veterinary practices. This is reflected by 4,681 dogs that have been either travelled to or relocated from endemic areas to Germany. The case history of these dogs and the laboratory findings have been compared with samples collected from 331 dogs living in an endemic area in Portugal. The various pathogens and the seroprevalences were examined to determine the occurrence of, and thus infection risk, for vector-borne pathogens in popular travel destinations.
