Phthiraptera Anoplura della Sardegna: analisi delle coinfestazioni ectoparassitiche rilevate su animali d'allevamento e selvatici
type: CreativeWork
description: The studies on arthropods of medical and veterinary importance carried out in Sardinia until now not yet provide a clear and comprehensive overview on the taxa present, their distribution, phenology and the pathogen role. Phthiraptera Anoplura (= Siphunculata), which includes the so called "sucking lice" was almost never investigated in Sardinia. They are small insects, obligatory permanent ectoparasites, characterized by a high host specificity and a high ethological, physiological and anatomical specialization, including the wingless. They feed on epidermal tissues, and the entire life cycle of the Anoplura takes place on the host. Heavy louse infestation may cause to their hosts pruritus, alopecia, weakness, irritability, weight loss and anaemia. They are also potential vectors of pathogens that can cause severe disease in domestic and wild animals as well as humans. One of the most famous can be considered the epidemic typhus whose etiologic agent is Rickettsia prowazeki. It is to be noted that the Anoplura have been little studied all around Italy and the few available published papers are occasional, sporadic and, apart from some recent works, already old. The aim of this PhD was to shed light on Phthiraptera Anoplura in Sardinia, taking into consideration the list of species present on the island, their distribution, phenology, and which mammals are parasitized. In this paper the Anoplura and other arthropod ectoparasites were collected on living and dead animals. The search for parasites was performed by examining the fur and skin of animals, concentrating on the areas of the body more vascularized and susceptible to localization of blood-sucking arthropods. So depending on the host species, was mainly look for the ectoparasites the regions of head, ears, neck, abdomen, the inguinal region and the perianal area. All arthropods found were fixed in 70% ethanol and later identified morphologically at the microscope. The collection of specimens in Sardinia provi…
