The following soil classes were identified in the studied area: Quartz Sands (AQ), Yellow Red Podzolic, Dusky Red Latosol (LR), 'Terra Roxa estruturada' (TE), Lithosol substrate sandstone (Lia) and Hidromorphic (Hi). The dimensional analysis method allowed: a) to group the watershed whose percentage (60%) are showing predominance of the same soil (Quartz Sands) and which located in the same relief; b) to group watersheds with different soil classes, but with similar percentages. -from English summary

To produce an epidemiological map of neosporosis in Brazil and identify the types of transmission of this disease, the present study evaluated the occurrence of Neospora caninum in Nelore cattle (Bos indicus) in Presidente Prudent, west region of Sao Paulo state; its vertical transmission; and the early stage in which fetuses are infected. To achieve this, serum samples from 518 slaughtered pregnant heifers and their fetuses were tested by ELISA technique and fetal brain tissues subjected to PCR. One hundred and three heifers (19.88%) had antibodies to N. caninum, as well as 38 (36.8%) of fetuses from 4 months of gestation. The conventional PCR failed to detect N. caninum DNA. These findings show that neosporosis occurs in the area studied and that it may be transmitted the transplacental route, althought N. caninum had not detected in brain tissue from non-aborted fetuses. The use of nested PCR it would be applied to increase the sensitivy of test.
