Technologies, 5975C) equipped with a fused-silica capillary column (DB-225MS, J W). Spectra have been recorded involving 50 and 600 Dalton in the electron effect ionization mode. The limit for quantitation of fatty acids was 20 ng. The absolute level of each and every fatty acid was connected towards the POC.Data evaluation and statisticsInfection efficiencies were analyzed using a generalized linear model (GLM) with logit function because the link function for binominal distribution. Therapy effects have been evaluated by assessing deviation from the grand mean. Numbers of offspring developed around the distinct foodSchlotz et al. BMC Ecology 2013, 13:41 http://biomedcentral/1472-6785/13/Page 9 ofregimes have been analyzed making use of a GLM with log function because the link function for quasi-Poisson distribution. To compensate for overdispersion the model was fitted employing quasi-Poisson errors [55]. To specify differences among meals regimes the subsets “control” and “infected” have been analyzed separately. For both GLMs, various comparisons among meals regimes were conducted together with the `multcomp package’ in R (R Improvement Core Group, 2010) working with general linear hypotheses testing as an implementation with the framework for simultaneous inference based on Hothorn et al. [56]. To test for variations in within-host reproduction in the parasite among food remedies one-way analyses of variance (ANOVA) were carried out followed by a number of comparisons (Tukey’s HSD); assumptions for ANOVA were met.Buy170853-04-0 All analyses had been performed using the statistical software program package R (v.2.12.0)peting interests The author(s) declare that they’ve no competing interests.
