Onchocerca lupi nematode in cat, Portugal

Onchocerca lupi (Spirurida, Onchocercidae) is a nematode that infects the ocular tissues of dogs and humans. This filarioid remained almost unknown until recently, when it was reported in dogs from Europe and North America. O. lupi was also detected in 2 cats from the United States, which suggests that not only canids but also felids are suitable hosts […]

Detection of Dirofilaria repens microfilariae in a dog from Portugal

Dirofilaria repens causes subcutaneous infection in dogs and cats, and is the main agent of human dirofilariosis in Europe. Detection of D. repens is described in a dog from Portugal, a finding that simultaneously represents the first presumable case of autochthonous infection with the parasite in any animal host species in the country. A mixed D. repens/Dirofilaria […]

Cercopithifilaria sp II in Vulpes vulpes: new host affiliation for an enigmatic canine filarioid

Cercopithifilaria bainae and Cercopithifilaria grassii (Spirurida, Onchocercidae) are filarioids inhabiting the skin of dogs worldwide. The microfilariae of a third species namely, Cercopithifilaria sp. II sensu Otranto et al. 2013, have been morphologically and molecularly characterized but scientific knowledge of this parasite is minimal. The first case of infection of a red fox (Vulpes vulpes) with the filarioid Cercopithifilaria sp. II is […]

Genetic characterization of Rhipicephalus sanguineus (sensu lato) ticks from dogs in Portugal

The taxonomic status of the brown dog tick Rhipicephalus sanguineus (sensu stricto) is a subject of on-going debate; there is a consensus that populations of this tick species should be referred to as R. sanguineus (sensu lato) until its taxonomic status is resolved. Recent genetic studies revealed the existence of more than one lineage of R. sanguineus (s.l.) in temperate countries. […]

Lungworms and gastrointestinal parasites of domestic cats: a European perspective

With the exception of Aelurostrongylus abstrusus, feline lungworms have been poorly studied. Information on their distribution is patchy and mostly limited to case reports. In this study, the occurrence of feline lungworms and co-infecting gastrointestinal parasites has been investigated in 12 European countries (i.e. Austria, Belgium, Bulgaria, France, Greece, Hungary, Italy, Portugal, Romania, Spain, Switzerland […]
