包括企鹅在内的许多海鸟都适应长时间禁食，特别是在生殖周期和换羽期间。然而，禁食对胃肠道（GI）微生物群的影响尚未在海鸟中进行过研究。因此，本研究的目的是检查胃肠道微生物群的微生物组成和多样性的禁食小企鹅（Eudyptula minor）和王企鹅（Aptenodytes patagonicus）企鹅在早期和后期换羽。从这项研究的结果表明，在换羽期间的主要门的丰度变化不大，除了变形菌在王企鹅的水平显着增加。在王企鹅中，梭杆菌的丰度从换羽早期的1.73%增加到换羽晚期的33.6%，而变形菌（35.7%到17.2%）和拟杆菌（19.5%到11%）的丰度从换羽早期到晚期下降。在小企鹅中，厚壁菌门的丰度从蜕皮早期到后期分别下降（44%到29%）和拟杆菌门的丰度增加（11%到20%）。这项研究的结果表明，国王和小企鹅的微生物组成在禁食期间发生了变化。然而，国王企鹅的微生物组成似乎比小企鹅更受禁食的影响，禁食的时间是造成这种差异的最可能原因。
Many seabirds including penguins are adapted to long periods of fasting, particularly during parts of the reproductive cycle and during moult. However, the influence of fasting on the gastrointestinal (GI) microbiota has not been investigated in seabirds. Therefore, the present study aimed to examine the microbial composition and diversity of the GI microbiota of fasting little (Eudyptula minor) and king penguins (Aptenodytes patagonicus) penguins during early and late moult. The results from this study indicated that there was little change in the abundance of the major phyla during moult, except for a significant increase in the level of Proteobacteria in king penguins. In king penguins the abundance of Fusobacteria increases from 1.73% during early moult to 33.6% by late moult, whilst the abundance of Proteobacteria (35.7% to 17.2%) and Bacteroidetes (19.5% to 11%) decrease from early to late moult. In little penguins, a decrease in the abundances of Firmicutes (44% to 29%) and an increase in the abundance of Bacteroidetes (11% to 20%) were observed from early to late moult respectively. The results from this study indicate that the microbial composition of both king and little penguins alters during fasting. However, it appears that the microbial composition of king penguins is more affected by fasting than little penguins with the length of fast the most probable cause for this difference.
