Abstract. The Colônia Deep Drilling Project held its first International Continental Scientific Drilling Program (ICDP) workshop in September 2014 at the University of São Paulo (Brazil). Twenty-seven experts from six countries discussed the feasibility and the expectations of a deep drilling in the structure of Colônia located at the southwestern margin of the city of São Paulo. After presenting the studies performed at the site during the last decades, participants focused on the objectives, priorities and detailed planning for a full deep-drilling proposal. An excursion to the site and new auger coring showed the importance of the Colônia site for studying the evolution of a tropical rainforest and to evaluate the interplay between the South American summer monsoon, the Intertropical Convergence Zone (ITCZ) and the southern Westerlies belt during the last 5 million years. In addition, deep drilling will eventually solve the still unresolved issue of the origin of the structure of Colônia as a result of meteorite impact or endogenous processes.

Abstract Capybaras (Hydrochoerus hydrochaeris) are the largest rodents found in South America. The aim of the present study was to investigate the occurrence of anti-Toxoplasma gondii and anti-Neospora caninum antibodies in 170 free-living capybaras in a residential park area in Itu Municipality, São Paulo State, Brazil. Serum samples were tested by indirect fluorescent antibody test (IFAT) for T. gondii (IFAT ≥ 1:16) and N. caninum (IFAT ≥ 1:50). Among the 170 samples analyzed, 10% (17/170) and 0% (0/170) were seropositive for T. gondii and N. caninum, respectively. This study confirms the widespread presence of T. gondii and reinforces the role of capybaras in the life cycle of this parasite. Capybaras may not be important as intermediate hosts of N. caninum in the studied environment.

This study aimed to determine the prevalence of dogs seropositive for Toxoplasma gondii and Neospora caninum (Apicomplexa) and the risk factors associated with seropositivity in the dog population of Ibiúna, São Paulo, Brazil. A total of 570 animals were examined in the 48 neighborhoods of the city from September 2007 to March 2008. Serological diagnosis of T. gondii and N. caninum infections was performed using indirect immunofluorescence assay (IFA), with endpoint titers of 1:64 for T. gondii and 1:50 for N. caninum. Of the 570 animals examined, 314 (55.1%; 95% CI = 50.9?59.2%) were seropositive for T. gondii and 40 (7.02%; 95% CI = 5.1?9.4%) for N. caninum. The variables presence of rodents (OR = 2.05), ingestion of raw meat (OR= 2.47), and prior sexual activity (OR = 1.79) were identified as risk factors for toxoplasmosis, whereas only prior sexual activity (OR = 3.29) was associated with an increased risk for neosporosis. Both T. gondii and N. caninum infections were detected by IFA in the dog population of Ibiúna. Rodent control and not feeding raw meat to dogs are important to reduce the risk of infection by T. gondii and N. caninum in the region.

RESUMO: Objetivou-se avaliar a ocorrência, sinais clínicos e fatores de risco associados a soropositividade para Toxoplasma gondii e Neospora caninum em ovinos. Foram utilizados 294 animais com histórico de distúrbios reprodutivos de 28 fazendas do estado de São Paulo, Brasil, diagnosticados através da imunofluorescência indireta (1:64 e 1:50). A ocorrência de T. gondii foi de 29,9% (88/294) e de N. caninum 18% (53/294), sendo 3,7% (11/294) dos ovinos soropositivos para ambos. Observou-se com maiores chances à infecção pelo T. gondii: ovinos mestiços (p=0,04), Santa Inês (p=0,006), fornecimento de pastagem (p<0,001) ou associada a concentrado (p<0,001), uso exclusivamente de monta natural (p=0,002, OR=2,28 e IC95%=1,37-3,79) e a presença de aves nas propriedades (p=0,001). Na infecção por N. caninum essa chance aumentou em: fêmeas (p=0,031), propriedades sem aprisco (p<0,001) e sistema de criação semi-intensivo (p<0,001). Em relação ao histórico de problemas reprodutivos, ovelhas infectadas pelo N. caninum e T. gondii apresentaram redução da chance de apresentarem abortamento (p=0,044) e repetição de estro (p=0,025) respectivamente. O T. gondii esteve mais presente sorologicamente que o N. caninum em ovinos com histórico de distúrbios reprodutivos e apesar de suas semelhanças, diferiram epidemiologicamente em aspectos relacionados as características da criação como raça, sexo, sistema de criação, tipo de alimentação e manejo reprodutivo.
