    Neosomes of tungid fleas on wild and domestic animals.
    Parasitol Res 2014 Oct 21;113(10):3517-33. Epub 2014 Aug 21.
    Departamento de Parasitologia, Instituto de Ciências Biológicas da Universidade Federal de Minas Gerais, Caixa Postal 486, Avenida Antônio Carlos, 6627, Campus UFMG, Belo Horizonte, Minas Gerais, 31270-901, Brazil,
    Tunga is the most specialized genus among the Siphonaptera because adult females penetrate into the skin of their hosts and, after mating and fertilization, undergo hypertrophy, forming an enlarged structure known as the neosome. In humans and other warm-blooded animals, neosomes cause tungiasis, which arises due to the action of opportunistic agents. Although its effects on humans and domestic animals are well described in the literature, little is known about the impact of tungiasis on wild animals. Read More
