“…The histogram of relative phylum abundance showed that regardless of the Periplaneta americana in eggs, nymph or adult stages, Bacteroidetes, Firmicutes and Proteobacteria were the predominant bacteria. Many previous studies have shown that both Bacteroidetes and Firmicutes are associated with the nutrient absorption of the host such as digestion of the carbohydrates that synthesize short chain fatty acids(Macfarlane and Macfarlane 2003;Liu et al 2017). Recent studies suggested that Bacteroidetes seem to establish a close interaction with their host early in lifetime and played an important role in the immunomodulation of their host(Ivanov et al 2008;Gibiino et al 2018).…”

Gut microbes play critical roles in host nutrition, physiology, and behavior. Periplaneta americana is a famous urban pest which is widely distributed in the tropics and subtropics, but very few information is available on the gut microbiome of Periplaneta americana, particularly in its different life stages. Here, we characterized the diversity and structure of gut microbiome in eggs, nymph and adult life stages of Periplaneta americana using high-throughput 16S rRNA genes sequencing. Both the results of Alpha- and Beta-diversity analysis showed the diversity and structure of gut microbiome were significant different among the eggs, nymph and adult stages. The result of species distribution showed the predominant phyla in three life stages were Bacteroidetes , Firmicutes and Proteobacteria , but the relative abundances of these bacteria were significant different among each life stage. 1,169 operational taxonomic units were shared by three stages, which indicating the gut microbiome may be inherited to offspring from parents of Periplaneta americana. According to the prediction of functional genes in metabolic pathways, most of them were distributed in the metabolic pathways of basic physiology such as nutrition, growth, development and immunity, etc. The relative abundances of functional genes in metabolic pathways were significant different among life stages of Periplaneta americana, indicating the gut microbiome might play an important role in the physiology across its different life stages. This study revealed the diversity and structure of gut microbiome in different life stages of Periplaneta americana, which may contribute to us to understand it’s physiology and behaviors.

Folic acid (FA) plays an essential role in the functioning of the gut and serves as an antioxidant. Therefore, dietary supplementation with high levels of FA may improve gut health and prevent oxidative stress caused by feeding a high energy density diet to broiler chickens. Broiler chickens were assigned into eight treatments, consisting of either a normal energy (NE) or high energy (HE) density diet, and four FA levels (2.2, 5, 10, and 15 ppm). Data were analyzed by SAS 16 GLM procedure. Birds fed HE diets had increased (P<0.05) plasma concentrations of calcium and albumin but reduced (P<0.005) weights of ceca and bursa compared to those fed NE diets. Dietary supplementation with 10ppm FA significantly increased (P<0.05) birds’ heart weight and bile acid concentration. FA and energy density interactions were significant for jejunal villus height (VH; P=0.0226), villus width (VW; P<0.0001), and crypt depth (CD; P=0.0332). Among the NE group, birds fed 5-15ppm FA had reduced (P<.0001) VW, while in the HE groups, 15ppm FA supplementation resulted in an increased jejunal VH (P=0.0317) compared to other treatments. In conclusion, dietary supplementation with increased levels of FA in HE diets could be beneficial for the intestinal health of broiler chickens.
