Spatio-temporal GAMLSS modeling of the incidence of schistosomiasis in the central region of the State of Minas Gerais, Brazil.

In Brazil, millions of people live in areas with risk of schistosomiasis, a neglected chronic disease with high morbidity. The Schistosoma mansoni helminth is present in all macroregions of Brazil, including the State of Minas Gerais, one of the most endemic states. For this reason, the identification of potential foci is essential to support educational and prophylactic public policies to control this disease.

First report of an autochthonous human visceral leishmaniasis in a child from the South of Minas Gerais State, Brazil.

American visceral leishmaniasis (VL) is a vector-borne disease transmitted by some species of phlebotomine sandflies from the genus Lutzomyia. This neglected tropical zoonosis shows increasing urbanization process, since the end of the 1980s. After the emergence of foci of the disease in urban areas, VL has assumed an important role in public health.

Occurrence of Fasciola hepatica (Linnaeus, 1758) infection in Brazilian cattle of Minas Gerais, Brazil.

Fasciolosis is a parasitic disease which is caused by digenetic trematodes, such as Fasciola hepatica, and which occurs worldwide. The disease causes significant economic losses in cattle because of the reduction in milk and meat production and because the parasitized livers have no economic value. Also, abortion and mortality rates increase.

Vaccine-induced protection against Leishmania amazonensis is obtained in the absence of IL-12/23p40.

Protozoa of the genus Leishmania are intracellular parasites of macrophages and may cause diverse clinical forms of leishmaniasis, including cutaneous, diffuse cutaneous, mucocutaneous and visceral leishmaniasis. Infection with L. major in mice indicates that a protective immune response is achieved when Th1 cells are developed.

Angiostrongylus vasorum (Baillet, 1866) Kamensky, 1905: emergence of third-stage larvae from infected Biomphalaria glabrata snails.

Biomphalaria glabrata snails were experimentally infected with Angiostrongylus vasorum first-stage larvae and divided into four groups of 30 snails. To assess the shedding of third-stage larvae (L3), the snails were maintained under different stimuli: group 1 60 W light bulb for 24 h, group 2 37 degrees C water bath for 24 h, group 3 room temperature (23-25 degrees C) for 24 h, Group 4 room temperature (23-25 degrees C) for up to 15 days. After 24 h, a total of 512 A.
