Ectoparasites detected on a red fox (Vulpes vulpes Linnaeus, 1758) in Turkey and the first case of Hippobosca longipennis (Diptera: Hippoboscidae) Full text

The aim of this case presentation is to report ectoparasites detected in one red fox. The adaptation of red foxes to urban environments and their increasing number result in an increased risk of transmission of some ectoparasites and pathogens originating from ectoparasites to humans and domestic animals. In this study, one red fox (Vulpes vulpes) which was after a traffic accident was examined for ectoparasites in the Clinic of Hatay Mustafa Kemal University, Faculty of Veterinary. A total 14 flies, 13 ticks and 4 fleas were collected from the red fox. As a result of the microscopic examinations of ectoparasites, Hippobosca longipennis (9 ♀, 5 ♂), Rhipicephalus turanicus (8 ♀, 5 ♂), Ctenocephalides felis (1 ♀) and Pulex irritans (2 ♀, 1 ♂) were identified. With this study, Hippobosca longipennis was recorded from foxes for the first time in Turkey.

The efficacy of two methods of spraying of acaricides on tick-infested sheep and goats was assessed. Two pyrethroid acaricides, 0.15% sumicidin and 0.20% butox were sprayed on individual animal one by one or on group of ten animals kept in small enclosures at a time, totally involving 40 sheep and 40 goats for each method. The efficacy, as seen from the total efficacy score (TES) of the former method of spraying, was found to be higher than the latter. But the advantages of the group spraying were that it saved the time in spraying and the quantity of acaricidal emulsion.

The proteolytic activities present in midguts of both fed and unfed Haemaphysalis longicornis were assessed by using the gelatin-substrate gel electrophoresis and inhibitor sensitivity analyses. Three predominant (116, 48 and 40 kDa) and two weak (55 and 60 kDa) proteinase bands were commonly expressed in both unfed and fed ticks, while a weak 80 kDa band was only present in fed ticks. Consistent with observations on other tick species, proteolytic activity against the gelatin substrate was observed only under acidic conditions. Inhibition studies against the gelatin substrate using a panel of inhibitors showed that the predominant proteolytic enzymes of 40 and 48 kDa molecular mass are cysteine proteinases. These results are discussed in the context of host vaccination as an alternative tick control method to the current use of chemical acaricides
Show more [+] Less [-]Blood meal acquisition by ticks; molecular advances and implications for vaccine development

Mulenga, A. (Hokkaido Univ., Sapporo (Japan)) | Tsuda, A. | Sugimoto, C. | Onuma, M.
In their quest for a blood meal, hematophagous arthropods must first defeat the host's hemostatic defense. Following injury as it occurs when hematophagous arthropods insert their proboscis into host skin to feed, the host will attempt to stop excessive blood loss through its hemostatic defense mechanism involving platelet aggregation, blood clotting and vasoconstriction. To acquire a full blood meal hematophagous arthropods inject an arsenal of bioactive enzymes which ultimately overpower the host's hemostatic defense. We have looked at a selected number of studies on the molecular biology of arthropod anti-hemostatic proteins and developed commentaries on the suitability of these molecules as target tick vaccine antigens.
