A correlation of Mycobacterium bovis SB0134 infection between cattle and a wild boar (Sus Scrofa) in Campania region.

A case of Mycobacterium bovis infection is described in a death adult female wild boar in the province of Avellino, Campania Region (Southern Italy). The carcass was sent to the Istituto Zooprofilattico Sperimentale del Mezzogiorno (IZSM) of Portici, Naples, Italy, where postmortem examination was performed. At necropsy, a disseminated granulomatous infection was observed, with involvement of various lymph node districts, spleen and lungs. Therefore, all lymph nodes were collected, together with spleen and lung lesions, in order to carry out bacteriological and molecular analyses that confirmed an uncommon disseminated Mycobacterium bovis infection. Subsequently, an analysis of the spoligotype, performed by the National Reference Center of Mycobacterium bovis in Brescia (Northern Italy), resulted in the spoligotype SB0134, previously identified in bovine outbreaks in the same area where the wild boar was found.

Massive Taenia hydatigena Cysticercosis in a Wild Boar (Sus scrofa) from Italy.

PURPOSE: Taenia hydatigena cysticercosis, due to Cysticercus tenuicollis, is a parasitic disease infecting domestic and wild animals worldwide causing economic and productive losses. Nonetheless, little attention has been paid to the role of the wild ungulates in the epidemiology of this disease. In the last years, the increasing population of wild boars in Europe has raised the attention of researchers on their role in the spreading of several infections, including those caused by cestodes. Herein, we report the description of a massive infection due to T. hydatigena cysticercosis in a wild boar from southern Italy. METHODS: An adult female boar was examined during the hunting season 2018 within the regional project "Piano Emergenza Cinghiali in Campania". A complete necropsy was performed on the boar carcass and all viscera were examined to determine number and location of the cysts. Morphological and molecular analyses of the cysts were performed to confirm the C. tenuicollis identity. RESULTS: The boar examined has revealed an impressive massive infection with 265 cysts. Measurements of the large and small larval hooks showed a mean of length as 200.3 µm and 136.8 µm, respectively. Molecular analysis of Cox1 and ND1 mitochondrial genes confirmed the C. tenuicollis identity. CONCLUSIONS: Our findings suggest that wild boar could be involved in the epidemiology of T. hydatigena, due to the significant amount of boar raw offal available to definitive hosts (i.e., hunting dogs, foxes and wolves), during the hunting seasons.
