Effect of carcass contamination on gut microbial community activity and composition. A Microbial activity (expressed as the relative dehydrogenase activity) for control and the exposed beetles (data point in parentheses was excluded from analysis; n = 9 for control, n = 10 for exposed, p = 0.084). B Statistical separation of bacterial community (metabolic) composition in exposed and control treatments as illustrated by a PCA analysis of the Biolog substrate utilization profiles of the bacterial communities (n = 5 for control, n = 4 for exposed, ANOSIM p = 0.030). C Gut microbial composition of control beetles (left, n = 5) and exposed beetles (right, n = 4) presented as percentages of the overall number of colony-forming units for each of the treatments on CHROMagar plates. Asterisks indicate that no unit of that taxa was found. Assessment of the differences in species between control (left, n = 5) and treatments (right, n = 4) suggests nanoparticles decrease the abundance of Candida and Serratia while promoting the growth of Alcaligenes, Morganella, and Pseudomonas (Z-tests scoring p < 0.05)
