Cystic echinococcosis (CE) due to Echinococcus spp. and Taenia hydatigena cysticercosis due to Cysticercus tenuicollis are widespread parasitic diseases infecting domestic and wild animals. These metacestodosis cause economic and productivity losses in both the developing and industrialized countries (Miran et al., 2017). Several studies investigated metacestodosis in domestic pigs, however, data in wild boars are scant. In the last years the wild boar population in Italy is increased (Massei et al., 2015) and this ungulate could play an important role in the spreading of metacestodosis in wildlife. This survey was carried out in order to determine prevalence and distribution of CE and Cysticercus tenuicollis in the wild boar in Campania Region. The carcasses of wild boars, shot down in different hunting areas, were examined during two hunting seasons (2016-2017) within the regional project “Piano Emergenza Cinghiali in Campania”. A detailed form was collected for each animal, including origin, gender and age. When hydatid cysts were found, their number, morphology and fertility were determined by visual and microscopic examination (Varcasia et al., 2006).

Out of a total of 2,107 wild boars examined, 92 (4.4%) and 142 (6.7%) were found positive to CE and cysticercosis, respectively. Co-infection were reported in 3 animals (1.3%). Hydatid cysts collected were 122, of which 118 (96.7%) in the liver and 4 (3.3%) in the lungs. Cysts were 27 (22.1%) fertile, 43 (35.3%) sterile and 52 (42.6%) acephalocyst.

Abstract
Cystic echinococcosis (CE) due to Echinococcus spp. and Taenia hydatigena cysticercosis due to Cysticercus tenuicollis are widespread parasitic diseases infecting domestic and wild animals. These metacestodosis cause economic and productivity losses in both the developing and industrialized countries (Miran et al., 2017). Several studies investigated metacestodosis in domestic pigs, however, data in wild boars are scant. In the last years the wild boar population in Italy is increased (Massei et al., 2015) and this ungulate could play an important role in the spreading of metacestodosis in wildlife. This survey was carried out in order to determine prevalence and distribution of CE and Cysticercus tenuicollis in the wild boar in Campania Region. The carcasses of wild boars, shot down in different hunting areas, were examined during two hunting seasons (2016-2017) within the regional project “Piano Emergenza Cinghiali in Campania”. A detailed form was collected for each animal, including origin, gender and age. When hydatid cysts were found, their number, morphology and fertility were determined by visual and microscopic examination (Varcasia et al., 2006). Number and position of cysticerci were recorded and their morphological identification was performed according to Scala et al. (2015). Out of a total of 2,107 wild boars examined, 92 (4.4%) and 142 (6.7%) were found positive to CE and cysticercosis, respectively. Co-infection were reported in 3 animals (1.3%). Hydatid cysts collected were 122, of which 118 (96.7%) in the liver and 4 (3.3%) in the lungs. Cysts were 27 (22.1%) fertile, 43 (35.3%) sterile and 52 (42.6%) acephalocyst. A total number of 170 cysticerci was found, of which 131 (77.0%) on the liver, 20 (11.8%) on the omentum, 10 (5.9%) on the spleen 7 (4.1%) on the lungs and 2 (1.2%) on the diaphragm. Boars presenting a single cisticerco were 121 (85.2%), while 21 (14.8%) more than one. Additional molecular studies are needed to evaluate the epidemiological role of wild boar in the transmission of metacestodosis in Italy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
