“… Ma et al (2020) revealed that the diversity of gut bacterial community in diarrheic rats was significantly decreased. Additionally, He et al (2020) demonstrated a decreased alpha diversity of the gut bacterial community in diarrheic piglets. Consequently, diarrheic giraffes may be accompanied by significant changes in the gut microbial composition and structure.…”

“…Generally, gut microbiota is dynamically diverse within limits and influenced by multiple factors such as species, age, sex, diet, and health status ( Manichanh et al, 2012 ; Wang et al, 2020 ; Xiong et al, 2020 ; Zhu et al, 2020 ). Several studies have indicated that diarrhea was able to cause a significant decrease in the diversity of gut bacterial community as well as shifts in intestinal functions ( Barash et al, 2017 ; He et al, 2020 ). Ma et al (2020) revealed that the diversity of gut bacterial community in diarrheic rats was significantly decreased.…”

“…Consistent with previous studies, this study demonstrated a dramatically declined ACE index in the gut bacterial community of giraffe during diarrhea, implying the disorder of gut bacterial community. Several previous studies have demonstrate that the abundance and diversity of gut microbiota was positively related to intestinal functions, thereby the intestine with higher microbial diversity and abundance favors the energy utilization and performing complicated physiological functions ( Barash et al, 2017 ; He et al, 2020 ). Furthermore, imbalanced gut microbiota may result in increased intestinal permeability and decreased immunity, which may further promote the invasion by members of pathogenic bacteria and conditioned pathogen ( Barash et al, 2017 ).…”

“…Therefore, some inevitable associations may be present between alternations in gut microbial community and diarrhea, but its specific connections and laws remain to be determined. Previously, numerous studies were performed on pathogenic bacteria, parasite, and virus to reveal the cause of ruminant diarrhea ( Gallardo et al, 2020 ; He et al, 2020 ). Recent studies on gut microbiota of goat, yak, and mice have provided evidence that gut microbial dysbiosis may be one of the reasons of diarrhea ( Han et al, 2017 ; Shao et al, 2020 ).…”

Gut microbiota has been demonstrated to be associated with multiple gastrointestinal diseases, but information regarding the gut microbial alternations in diarrheic giraffe remains scarce. Here, 16S rDNA and ITS gene amplicon sequencing were conducted to investigate the gut microbial composition and variability in diarrheic giraffes. Results demonstrated that Firmicutes and Proteobacteria were the most dominant phyla in the gut bacterial community, whereas Ascomycota and Basidiomycota were observed to be predominant in the gut fungal community regardless of health status. However, the species and relative abundance of preponderant bacterial and fungal genera in healthy and diarrheic giraffes were different. In contrast to the relatively stabilized gut fungal community, gut bacterial community displayed a significant decrease in the alpha diversity, accompanied by distinct changes in taxonomic compositions. Bacterial taxonomic analysis revealed that the relative abundances of eight phyla and 12 genera obviously increased, whereas the relative abundances of two phyla and eight genera dramatically decreased during diarrhea. Moreover, the relative richness of five fungal genera significantly increased, whereas the relative richness of seven fungal genera significantly declined in diarrheic giraffes. Taken together, this study demonstrated that diarrhea could cause significant alternations in the gut microbial composition of giraffes, and the changes in the gut bacterial community were more significant than those in the gut fungal community. Additionally, investigating the gut microbial characteristics of giraffes in different health states is beneficial to provide a theoretical basis for establishing a prevention and treatment system for diarrhea from the gut microbial perspective.

“…Currently, many measures have been conducted to prevent diarrhea, but it still presently displays a high prevalence rate. Research into gut microbiota has recently revealed its essential role in developing diarrhea (30,31). Therefore, investigating the gut microbial composition and structure is of great significance for preventing and treating diarrhea.…”

The ruminant gut microbial community's importance has been widely acknowledged due to its positive roles in physiology, metabolism, and health maintenance. Diarrhea has been demonstrated to cause adverse effects on gastrointestinal health and intestinal microecosystem, but studies regarding diarrheal influence on gut microbiota in Giraffa camelopardalis have been insufficient to date. Here, this study was performed to investigate and compare gut microbial composition and variability between healthy and diarrheic G. camelopardalis. The results showed that the gut microbial community of diarrheal G. camelopardalis displayed a significant decrease in alpha diversity, accompanied by distinct alterations in taxonomic compositions. Bacterial taxonomic analysis indicated that the dominant bacterial phyla (Proteobacteria, Bacteroidetes, and Firmicutes) and genera (Escherichia Shigella and Acinetobacter) of both groups were the same but different in relative abundance. Specifically, the proportion of Proteobacteria in the diarrheal G. camelopardalis was increased as compared with healthy populations, whereas Bacteroidetes, Firmicutes, Tenericutes, and Spirochaetes were significantly decreased. Moreover, the relative abundance of one bacterial genus (Comamonas) dramatically increased in diarrheic G. camelopardalis, whereas the relative richness of 18 bacterial genera decreased compared with healthy populations. Among them, two bacterial genera (Ruminiclostridium_5 and Blautia) cannot be detected in the gut bacterial community of diarrheal G. camelopardalis. In summary, this study demonstrated that diarrhea could significantly change the gut microbial composition and diversity in G. camelopardalis by increasing the proportion of pathogenic to beneficial bacteria. Moreover, this study first characterized the distribution of gut microbial communities in G. camelopardalis with different health states. It contributed to providing a theoretical basis for establishing a prevention and treatment system for G. camelopardalis diarrhea.
