Dirofilaria repens is a nematode affecting domestic and wild canids, transmitted by several species of mosquitoes. It usually causes a non-pathogenic subcutaneous infection in dogs and is the principal agent of human dirofilariosis in the Old World. In the last decades, D. repens has increased in prevalence in areas where it has already been reported and its distribution […]

The Role of Reservoirs: Canine Leishmaniasis

  • Journal: Drug Resistance in Leishmania Parasites

Canine leishmaniasis caused by Leishmania (Leishmania) infantum species (syn. L. (L.) chagasi species in Latin America), which is transmitted by the bite of phlebotomine sand flies, is endemic and affects millions of dogs in Asia, Europe, North Africa, and South America and is considered as an emergent disease in North America. Domestic dogs (Canis familiaris) are the major hosts for these parasites and […]

Epidemiological and genetic studies suggest a common Leishmania infantum transmission cycle in wildlife, dogs and humans associated to vector abundance in Southeast Spain

Leishmania infantum infection was investigated in 202 wild carnivores, rodents and lagomorphs in Southeast Spain using a real-time PCR (rtPCR) in skin and organ samples, mostly spleen. Lesions compatible with leishmaniosis were not observed in any of the animals. Prevalence defined as the percentage of rtPCR-positive animals was 32% overall, and 45% in foxes (n = 69), 30% […]

Parasite biology: The reservoir hosts

  • Journal: The Leishmaniases: Old Neglected Tropical Diseases

Leishmaniases are worldwide vector-borne diseases with diverse clinical manifestations caused by protozoa belonging to genus Leishmania. About 20 named Leishmania species are pathogenic for humans and are annually responsible for 0.7–1.2 million cases of cutaneous and 0.2–0.4 million cases of visceral forms of the disease. According to the transmission cycle involving animals or humans, leishmaniasis can be […]

A real-time PCR tool for the surveillance of zoonotic Onchocerca lupi in dogs, cats and potential vectors

  • Autores: Latrofa MS, Annoscia G, Colella V, Cavalera MA, Maia C, Martin C, Šlapeta J, Otranto D
  • Ano de Publicação: 2018

  • Link: https://www.ncbi.nlm.nih.gov/pubmed/29617361

The ocular onchocercosis is caused by the zoonotic parasite Onchocerca lupi (Spirurida: Onchocercidae). A major hindrance to scientific progress is the absence of a reliable diagnostic test in affected individuals. Microscopic examination of skin snip sediments and the identification of adults embedded in ocular nodules are seldom performed and labour-intensive. A quantitative real-time PCR (qPCR) […]
