The prevalence of Mal de Cadeiras - Portuguese for Trypanosoma (T.) evansi infections in horses - as well as the prevalence of T. evansi infections in cattle, dogs and free-ranging capybaras (Hydrochaeris hydrochaeris) was investigated in Pantanal de Pocone (Mato Grosso, Brasil). In 0.3, 8.6 and 8.0% of the horses, dogs and capybaras, respectively, infection was detected using standard parasitological methods. A seroprevalence of 4.1, 2.3, 7.1 and 22.0% was found in horses, cattle, dogs and capybaras, respectively, using an enzyme-linked immunosorbent assay for the detection of T. evansi antigen (Ag-ELISA), whereas 9.6, 4.2, 18.6 and 14.0% of the animals investigated were reactive in a T. evansi antibody (Ab-) ELISA. Positive ELISA results (high responder) were identified using computer-assisted mixture analysis (C.A.MAN). Agglutinating antibodies were detected by the T. evansi card agglutination test for trypanosomiasis (CATT/T. evansi) in 14.6%, 1.3%, 15.7% and 22.0% of the horses, cattle, dogs and capybaras, respectively. A moderate but significant (kappa test; p<0.05) agreement beyond chance levels was observed between Ab-ELISA and CATT results but generally not between antibody and antigen detection tests. Therefore, in an attempt to maximize the information yield of the three serodiagnostic tests, their results were numerically scored (negative=0, intermediate=1, positive=2) and added up to a total score (TS) which was considered indicative for infection when TS>4 (results of the Ag-ELISA received double weight). Estimates of seroprevalence according to TS were 13.2, 4.7, 30.0 and 24.0% for horses, cattle, dogs and capybaras, respectively. Identical isoenzyme profiles, known as zymodeme 58 (T. evansi MCAN/BR/86/H), were found in all T. evansi stocks isolated in the study area (six from dogs, one from a horse and one from a capybara). From the results of this study it can be inferred that Mal de Cadeiras is endemic in Pantanal de Pocone. Although clinical and parasitological findings support the possible role of the capybara as a reservoir host of T. evansi, dogs and cattle - due to their close contaxct with horses should rather be regarded as efficient resrvoir hosts for Mal de Cadeiras in the study area.

ABSTRACT. This study aims to analyze the incorporation of basalt rock dust to a commercial substrate based on pine bark under two light conditions on initial growth of Monteverdia ilicifolia (Mart. Ex Reissek) Biral seedlings. We evaluated four proportions of rock dust: 0% (control), 10%, 20%, and 30% on plants kept unshaded and under 50% shading for 140 days. The unshaded condition associated with basalt rock dust incorporated to substrate presented the higher seedlings growth. Incorporating rock dust in any proportion to the substrate increased stem diameter and biomass, resulting in a greater Dickson quality index (DQI) in unshaded seedlings. The rock dust in a proportion of 10% showed better results in seedlings growth. Moreover, 20% and 30% of rock dust reduced stem diameter, biomass, and DQI, when compared to 10% of rock dust, possibly due to the substrate physical characteristics. We recommend incorporating 10% of rock dust to the pine bark-based substrate for M. ilicifolia seedlings production in an unshaded environment. TÍTULO: Pó de rocha basáltica incorporado ao substrato favorece o crescimento inicial de mudas de Monteverdia ilicifolia. RESUMO: Este estudo objetivou analisar a incorporação de pó de rocha basáltica ao substrato comercial a base de casca de pinus sob duas condições de luminosidade no crescimento inicial das mudas de Monteverdia ilicifolia (Mart. Ex Reissek) Biral. Foram testadas quatro proporções de pó de rocha: 0% (controle), 10%, 20% e 30% em plantas mantidas sem sombreamento e com sombreamento de 50%, por 140 dias. O cultivo sem sombreamento associado com a incorporação de pó de rocha ao substrato favoreceu o crescimento das mudas. A incorporação de pó de rocha em qualquer proporção incrementou o diâmetro do colo e a biomassa, resultando em maior índice de qualidade de Dickson (IQD) nas mudas sem sombreamento. A proporção de 10% de pó de rocha apresentou resultados melhores no crescimento das mudas. As proporções de 20% e 30% de pó de rocha reduziram o diâmetro do colo, a biomassa e o IQD, quando comparados com 10% de pó de rocha, possivelmente pelas características físicas do substrato. Nós recomendamos a incorporação de 10% de pó de rocha ao substrato a base de casca de pinus para o crescimento de mudas de M. ilicifolia, em ambiente sem sombreamento. MenosABSTRACT.
