“…Although the presence of A. dracunculoides in central and eastern Europe has not yet been reported despite systematic surveillance in both domestic and wild carnivores (Ionicȃ et al, 2015(Ionicȃ et al, , 2016(Ionicȃ et al, , 2017a(Ionicȃ et al, , 2017b, the presence of its vectors should raise awareness. However, the louse flies (Hippoboscidae) are not the sole vectors of this parasite as ticks [Rhipicephalus sanguineus sensu lato (Ixodida: Ixodidae)] have also been incriminated (Olmeda-Garcia et al, 1993;Olmeda-Garcia & Rodriguez-Rodriguez, 1994;Mihalca et al, 2012;Dantas-Torres & Otranto, 2015). Hence, the importance of this finding, together with the underlying factors determining the distribution of H. longipennis, require further investigation.…”

Abstract. Hippobosca longipennis (Diptera: Hippoboscidae), the dog fly or dog louse fly, is an obligate blood‐feeding ectoparasite of wild and domestic carnivores in Africa and the Middle East. Outside its typically known geographic range, H. longipennis has been reported occasionally on mainly domestic dogs in Asia and southern Europe, and infrequently in other areas (central Europe and the U.S.A.). This paper presents the first report of H. longipennis in Romania and the second record of Lipoptena fortisetosa (Diptera: Hippoboscidae), a potentially invasive species. Hippobosca longipennis was found on domestic dogs in two regions of the country (northern Romania in Maramures and southwestern Romania in Dobrogea) and on two road‐killed wildcats in Maramures. Lipoptena fortisetosa was found on domestic dogs in Maramures. In both species identification was based on morphology and confirmed by barcoding of the cytochrome c oxidase subunit 1 gene. It is not clear for how long H. longipennis has been present in central Europe, nor if it was introduced (via the movement of domestic dogs or import of exotic carnivores) or present historically (Holocene remnants). This paper discusses the possible origins of H. longipennis in central Europe as its current distribution in the area is sparse and patchy.

“…Hafez and Hilali [26] however demonstrated that the fly could only withstand starvation for 12 to 36 hours before dying and that feeding occurs more regularly than this. It is reported that the developmental period from L1 to infective larvae for A. reconditum in fleas and A. dracunculoides in ticks is approximately seven days and thirteen days, respectively [16,27]. The development of Acanthocheilonema sp.?…”

“…Fleas and lice are intermediate hosts for A. reconditum [14]. Ticks, lice [15,16] and, in Algeria, H. longipennis , have all been proposed as intermediate hosts for Acanthocheilonema dracunculoides [17]. The development of larvae in these intermediate hosts occurs mostly in the fat-body cells and infective larvae migrate to the mouthparts to facilitate their transmission [18,19].…”

Hippobosca longipennis - a potential intermediate host of a species of Acanthocheilonema in dogs in northern India

BackgroundHippobosca longipennis (the 'dog louse fly') is a blood sucking ectoparasite found on wild carnivores such as cheetahs and lions and domesticated and feral dogs in Africa, the Middle East and Asia, including China. Known as an intermediate host for Acanthocheilonema dracunculoides and a transport host for Cheyletiella yasguri, it has also been suggested that H. longipennis may be a vector for other pathogens, including Acanthocheilonema sp.? nov., which was recently reported to infect up to 48% of dogs in northern India where this species of fly is known to commonly infest dogs. To test this hypothesis, hippoboscid flies feeding on dogs in Ladakh in northern India were collected and subjected to microscopic dissection.ResultsA total of 12 infective larvae were found in 10 out of 65 flies dissected; 9 from the head, 2 from the thorax and 1 from the abdomen. The larvae averaged 2, 900 (± 60) μm in length and 34 (± 5) μm in width and possessed morphological features characteristic of the family Onchocercidae. Genetic analysis and comparison of the 18S, ITS-2, 12S and cox-1 genes confirmed the identity of the larvae as the Acanthocheilonema sp.? nov. reported in dogs in Ladakh.ConclusionThis study provides evidence for a potential intermediate host-parasite relationship between H. longipennis and the canine Acanthocheilonema sp.? nov. in northern India.

“…The brown dog tick (Rhipicephalus sanguineus) is well known as a vector of some pathogens of dogs such as Babesia canis [7,16], Babesia gibsoni [7,16], Hepatozoon canis [2], Ehrlichia canis [10], Coxiella burnetii [8], spotted fever group rickettsia [1], and the filaria nematode Dipetalonema spp [12,13]. However, there have been few reports on the distribution of R. sanguineus except in Okinawa Prefecture in Japan [18].…”

“…As the detail structure could not be observed in the smear, the species of the microfilaria was not identified. Rhipicephalus sanguineus is a vector of dog filaria, D. dracunculoides [12,13]. The microfilaria might have belonged to Dipetalonema spp.…”

ABSTRACT. Serological tests were performed to investigate extent of tick-borne diseases in dogs infested with Rhipicephalus sanguineus at a kennel in Okayama Prefecture. Three of 22 dogs (13.6%) were positive for Ehrlichia canis. Two of 19 dogs (10.5%) were positive for Rickettsia japonica. Three of 22 dogs (13.6%) were positive for Babesia gibsoni. None of these animals were positive for Coxiella burnetii or Hepatozoon canis. A microfilaria was detected in a drop smear of hemolymph from an engorged female tick, however species was not determined. It is possible that these ticks can transmit pathogens to domestic dogs which are rare in Japan. -KEY WORDS: canine, Rhipicephalus sanguineus, tick-borne disease.
