“…Imported Thelazia-cases in dogs which had been travelling to Italy were initially reported from France (Bussiéras et al 1996), southern Switzerland in 2000 4 (Malacrida et al 2008) and Germany (Hermosilla et al 2004). Subsequent investigations between 2005 and 2007 in southern Switzerland (canton Ticino) revealed prevalences in dogs and foxes of 6.2% and 11.1%, respectively, in the most southern part.…”

This report describes the first assumed locally transmitted case of the eye worm Thelazia callipaeda in a dog living in southern Germany. A four year old, male golden retriever from the town of Bühl in north eastern Baden-Württemberg, about 10 km from the German-French border, showed one sided lacrimation for over two weeks. Despite the application of antibiotics, there was no improvement, and the dog additionally showed blepharospasmus, epiphora and red conjunctivas. A deepened eye inspection revealed five whitish, filiform parasites which were morphologically identified as T. callipaeda. The partial sequence of the mitochondrial cytochrome c oxidase subunit 1 gene (cox1, 605 bp) from one specimen revealed a novel haplotype, which differs by 1.3% from the only one (haplotype 1) identified in Europe so far. Since the infected dog had never been abroad with the exception of two daytrips to the close Alsace region in France, the transmission of T. callipaeda most probably was domestic. With the presence of end hosts and Phortica flies nourishing on lachrymal secretions acting as intermediate hosts, and an increasing number of dogs travelling to and coming from endemic regions in the South, the establishment of T. callipaeda in large parts of Europe cannot be excluded.

In addition, five cats were also affected (Malacrida et al 2008). All these cats and 58% of the infected dogs never had left the country.…”

“…As an example, the term 'oriental eye worm' for Thelazia callipaeda (a vector-borne nematode of domesticated and wild canids) refers to its originally recognised distribution in Asia and the 'Far East' (from a Eurocentric perspective). However, this zoonotic parasite is rapidly emerging as a disease problem in animals and people in Mediterranean countries, and recent cases in Belgium, Germany, and Switzerland [11][12][13] have confirmed predictions inferred by ecological modelling [14] that its insect vector, Phortica variegata, might establish across much of Western Europe.…”

Keywords:Canine, vector-borne diseases, zoonosis, emerging disease, diagnosis, travel medicine, compliance AbstractCanine vector-borne diseases (CVBDs) comprise a diverse group of viral, bacterial, protozoal, and helminth pathogens, transmitted predominantly by ticks and fleas, and cause significant health problems for dogs worldwide. Growing numbers of reports indicate that CVBDs are emerging in regions where they previously did not exist and this, combined with pathogens that are inherently difficult to detect, is providing companion animal veterinarians with some significant diagnostic challenges. This review discusses six paradigms concerning the diagnosis, treatment, prevention, and zoonotic implications of CVBDs from a veterinary clinical perspective. Veterinarians are the key professionals at the companion animal: human interface. Not only do they provide the traditional medical and surgical services for pets, their training in the disciplines of parasitology, microbiology, epidemiology, and public health place them in a unique position to provide advice about matters pertaining to vector-borne diseases. Despite this, emerging canine vector-borne diseases (CVBDs) pose a number of significant and complex challenges for veterinarians in clinical practice whose responsibility it is to diagnose and treat these companion animals, while at the same time remaining mindful of the potential for disease transmission to the owners and other people living in close proximity, as well as to other susceptible animals [5]. As will be discussed here, many CVBDs are caused by organisms that are inherently difficult to detect, frequently cause nebulous clinical signs in their canine hosts, and are sometimes zoonotic. In addition, the rapid progress of scientific research in this area itself poses further challenges of how best to distil and disseminate this knowledge to busy veterinary practitioners worldwide at a time when every aspect of clinical practice is becoming more complex. How should practitioners keep current with information in this area so that they can provide appropriate evidence-based advice to their clients?

“…Climate in the countries where T. callipaeda has been reported varies from tropical (Indonesia) and subtropical (Japan) in the Far East to temperate in the Russian Federation. In Europe, infections by T. callipaeda have been reported in Italy (25), Germany (9), Switzerland (14), France (34), Spain (16), Portugal (13,38), Belgium (5), Serbia (18), and Romania (15).…”
