| anaplasma marginale and theileria annulata in questing ticks from portugal. | ticks are ubiquitous arthropods and vectors of several pathogenic agents in animals and humans. monitoring questing ticks is of great importance to ascertain the occurrence of pathogens and the potential vector species, offering an insight into the risk of disease transmission in a given area. in this study 428 host-seeking ticks, belonging to nine species of ixodidae and collected from 17 of the 23 portuguese mainland subregions, were screened for several tick-borne agents with veterinary relev ... | 2016 | 27394441 |
| patterns of tick infestation and their borrelia burgdorferi s.l. infection in wild birds in portugal. | wild birds may act as reservoirs for zoonotic pathogens and may be mechanical carriers of pathogen infected vector ticks through long distances during migration. the aim of this study was to assess tick infestation patterns in birds in portugal and the prevalence of tick infection by borrelia burgdorferi s.l. using pcr techniques. seven tick species were collected from birds including haemaphysalis punctata, hyalomma spp., ixodes acuminatus, ixodes arboricola, ixodes frontalis, ixodes ricinus an ... | 2015 | 26159798 |
| lyme borreliosis spirochetes and spotted fever group rickettsiae in ixodid ticks from pianosa island, tuscany archipelago, italy. | a study on tick fauna and tick-borne pathogens was undertaken in pianosa, an island in the tuscany archipelago that constitutes an important stopping and nesting point for migratory birds. ticks were removed from feral cats and a few terrestrial birds, and host-seeking ticks were collected by dragging. a total of 89 ticks were found on animals: 57 ixodes ventalloi gil collado, 1936 and 32 ixodes acuminatus neumann, 1901. host-seeking ticks were 354 hyalomma spp. larvae and 18 hyalomma spp. adult ... | 2013 | 23289398 |
| feline and canine leishmaniosis and other vector-borne diseases in the aeolian islands: pathogen and vector circulation in a confined environment. | vector-borne diseases (vbds) are prevalently investigated in dogs. studies on feline vbds are scant, though feline leishmaniosis (fel) is increasingly recognised as a disease of cats in endemic areas. comprehensive investigations on the distribution of vbds in populations of cats and dogs living in relatively small geographical areas, such as islands, are currently lacking. in this study the prevalence of leishmania infantum and other vbd pathogens was assessed in cohorts of cats and dogs living ... | 2017 | 28288759 |
| ectoparasite load in the crested porcupine hystrix cristata linnaeus, 1758 in central italy. | the crested porcupine hystrix cristata is a large body-sized rodent, occurring in europe only in the italian peninsula, where it may have been introduced in early medieval times. its parasite fauna is currently poorly known and limited to few anecdotal observations. we have analyzed the ectoparasite load of 165 crested porcupines from tuscany and latium (central italy). both captured and road-killed individuals were checked for fleas and ticks. overall, only 39 porcupines were infested by four s ... | 2015 | 25773184 |
| seasonal dynamics of ixodid ticks on wild rabbits oryctolagus cuniculus (leporidae) from central spain. | rabbit hemorrhagic disease and myxomatosis caused a decline in the rabbit population in the second half of the last century. despite some recovery, the risk of vector-borne disease is present and thus the importance of controlling vector populations. in the current study, we describe the ixodid tick fauna in wild rabbit in a natural reserve in ciudad real (central spain) during the course of two 3-year periods (2007-2009 and 2012-2014). of all the ticks collected on average 72.5 % were larvae, 2 ... | 2016 | 27411939 |
| season-long control of flea and tick infestations in a population of cats in the aeolian archipelago using a collar containing 10% imidacloprid and 4.5% flumethrin. | cats that have outdoor access are highly exposed to ticks, fleas, mites and flying insects, though the risk to become infested by arthropods is less perceived in cats than in dogs. this has resulted in fewer treatment and prevention options being available for cats than for dogs. a collar containing a combination of 10% imidacloprid and 4.5% flumethrin (seresto®, bayer animal health) is available for cats and licensed with claims against ticks and fleas for 7-8 months. following the assessment o ... | 2017 | 29173546 |
| the effect of excluding ungulates on the abundance of ixodid ticks on wild rabbit (oryctolagus cuniculus). | tick abundance depends heavily on host density, so reducing access to the host should reduce tick populations in a determined area. in this study we compared the parasitic index (pi = average number of ticks per rabbit) of two wild rabbit populations separated 16 years ago by a fence keeping ungulates from moving freely. two areas were selected (closed and open) wherein 50 wild rabbits per area were sampled for ticks. the pi in the open area (pi = 989.62) was significantly higher than in the clo ... | 2017 | 28840404 |
| ixodes ventalloi: morphological and molecular support for species integrity. | despite their medical and veterinary importance, some tick species are so poorly studied, that their role within pathogen vector transmission cycles is difficult to assess. the tick ixodes ventalloi is one such species, and its biology and phylogenetic status remain an issue of debate. in the present study, specimens of adult i. ventalloi (n = 65 females; n = 31 males) infesting cats in the lipari island (aeolian archipelago, sicily, southern italy) were characterized morphologically and molecul ... | 2017 | 27761719 |
