The taxonomic status of the brown dog tick (Rhipicephalus sanguineus sensu stricto), which has long been regarded as the most widespread tick worldwide and a vector of many pathogens to dogs and humans, is currently under dispute. We conducted a comprehensive morphological and genetic study of 278 representative specimens, which belonged to different(More)
This study describes a duplex real-time polymerase chain reaction (PCR) assay for the detection and differentiation between Dirofilaria immitis and Dirofilaria repens in dog blood and mosquitoes. Regions of a cytochrome oxidase 1 (cox1) mitochondrial DNA fragment and the second internal transcribed spacer (ITS-2) of nuclear ribosomal DNA were amplified from(More)
This study was aimed at investigating the distribution of a Cercopithifilaria sp. sensu Otranto et al., 2011 with dermal microfilariae recently identified in a dog from Sicily (Italy). A large epidemiological survey was conducted by examining skin samples (n = 917) and ticks (n = 890) collected from dogs at different time points in Italy, central Spain and(More)
The present study reports the applicability of a multiplex PCR for the simultaneous detection and differentiation of common filarioids infecting dogs, i.e., Dirofilaria immitis, Dirofilaria repens, Acanthocheilonema reconditum and Cercopithifilaria sp. Amplicons of different sizes (i.e., 170 bp, 480 bp, 590 bp and 300 bp, respectively) of regions within the(More)
Oslerus rostratus syn. Anafilaroides rostratus (Strongylida: Filaroididae) is a metastrongyloid transmitted by snails, which localizes in peri-bronchial tissues and in the lung parenchyma of wild as well as domestic cats. In Europe, this nematode has been reported only on two occasions, being diagnosed in cats from Majorca Island and in northern Spain.(More)
This study investigates sequence variation in mitochondrial cytochrome c oxidase subunit 1 gene within Cercopithifilaria sp. recorded recently in Italy. Fourteen sequence types (haplotypes) were characterized for 163 (7.7%) amplicons from 2111 Genomic DNA samples prepared from skin samples from dogs and from Rhipicephalus sanguineus (ticks) from different(More)
The present study reports two simple molecular approaches allowing a rapid identification of the most prevalent species of phlebotomine sand flies in the Mediterranean region. A PCR protocol for the amplification of ITS2 ribosomal region and a PCR-RFLP on a mitochondrial DNA fragment (cytb-nd1) were settled in order to identify and discriminate among(More)
Thelazia callipaeda (Spirurida, Thelaziidae), also known as “oriental eyeworm”, is a small nematode parasite that lives in the conjunctival sac of domestic and wild carnivores, rabbits and even humans, causing mild (e.g., conjunctivitis, epiphora, and ocular discharge) to severe (e.g., keratitis, and corneal ulcers) ocular disease. This study reports, for(More)
Aelurostrongylus abstrusus is currently regarded as the main metastrongyloid infesting domestic cats, whereas the reports of Troglostrongylus spp. in domestic and wild felids largely remain anecdotic. This paper reports on pulmonary infestation caused by Troglostrongylus brevior and Troglostrongylus subcrenatus in two kittens and describes, for the first(More)
Dirofilaria immitis and Dirofilaria repens are transmitted by bloodsucking culicid mosquitoes belonging to Culex, Aedes, Ochlerotatus, Anopheles and Mansonia genera. The detection of filarioids in mosquitoes for assessing distribution of vectors and/or of pathogens in a given area (also known as “xenomonitoring”), when based on individual dissection of(More)
