Microscopic agglutination test on captive rattlesnakes : Data on serovars and titers
The microscopic agglutination test (MAT) is considered the âgolden standardâ leptospirosis serodiagnostic test, but there is little information about it as it pertains to snakes. To fill this information gap, we provide data on serovars and titers of fifty-six Crotalus durissus collilineatus sera samples that tested positive by MAT (10.1016/j.actatropica.2016.02.006 (Rodrigues et al., 2016) [5]). These data are presented in a table, along with a description of the methodology used for sample collection and serologic testing
An adapted thermal-gradient block for the germination of photoblastic seeds
This work describes an adapted thermal-gradient block with internal illumination, allowing experiments with light-requiring seeds. The temperature dependence study on the germination of the photoblastic Plantago tomentosa seeds was carried out in order to test the performance of the apparatus. With the aid of the model described here, some parameters related to the response of the seeds to temperature could be estimated, showing that the apparatus was suitable for the studies on the temperature dependence of photoblastic seeds.<br>Este trabalho descreve um bloco termo-gradiente com iluminação interna, adaptado para estudos com sementes que requerem luz para germinar. Para se aferir o desempenho do equipamento, este foi usado num experimento sobre o efeito da temperatura na germinação de sementes fotoblĂĄsticas de Plantago tomentosa. Com o protĂłtipo aqui descrito, alguns parĂąmetros da resposta dessa semente Ă temperatura puderam ser estimados, mostrando que o equipamento pode ser usado em estudos sobre a dependĂȘncia tĂ©rmica da germinação de sementes fotoblĂĄsticas
