The wild rodent Akodon azarae (Cricetidae: Sigmodontinae) as intermediate host of Taenia taeniaeformis (Cestoda: Cyclophyllidea) on poultry farms of central Argentina
This work reports strobilocerci of Taenia taeniaeformis in the rodent Akodon azarae. A total of 289 rodents were captured on poultry farms in Central Argentina, belonging to the following species: A. azarae, Calomys laucha, C. musculinus, Oligoryzomys flavescens, and Mus musculus. All rodents were e...

| Sumario: | This work reports strobilocerci of Taenia taeniaeformis in the rodent Akodon azarae. A total of 289 rodents were captured on poultry farms in Central Argentina, belonging to the following species: A. azarae, Calomys laucha, C. musculinus, Oligoryzomys flavescens, and Mus musculus. All rodents were examined for parasites. Only A. azarae was parasitized with strobilocerci larvae. Prevalence, mean intensity, and mean abundance of the infection in the liver were 8.33%, 2.09 and 0.17, respectively. No differences were observed between the sexes of the infected rodents. Since in natural environments no cysts were reported, A. azarae is susceptible to get infected with T. taeniaeformis when frequents domestic and peridomestic habitats. Taenia taeniaeformis may have three different life cycles in the studied area: 1) one domestic cycle between Rattus norvegicus and pets in the surrounding of the farms, since R. norvegicus was observed to be parasitized; 2) another domestic cycle between A. azarae and the pets when such pets come to the farm fences; and 3) a wild cycle between A. azarae and Leopardus geoffroyi (Carnivora: Felidae), since it was observed that A. azarae is preyed by this felid and their feces were found parasitized with eggs of Taenia sp. in the study area. |
