Summary: The microbiome composition of African penguins is influenced by host diet, environment, and phylogenetic relatedness. Penguins born under managed care have a gut microbiome more similar to that of wild birds, while their oral microbiome is more similar to that of piscivorous marine mammals. Additionally, there is microbial sharing between animals and their habitat at external body sites.

Summary: The African penguin is an endangered species and little is known about its intestinal microbiota. This study investigated the composition and diversity of the intestinal microbiota in captive African penguins. The results showed that Proteobacteria, Actinobacteria, and Firmicutes were the dominant bacteria in the intestinal microbiota. Female African penguins had a higher abundance of Pseudomonas, a common avian pathogen, indicating that the intestinal health of female African penguins in captivity might require more attention.

Summary: This study investigated the occurrence of Chlamydiaceae-like bacteria in wild Magellanic penguins. DNA from Chlamydiaceae-like bacteria was detected in cloacal swabs, and phylogenetic analysis showed a close relationship to unidentified Chlamydiaceae-like bacteria found in chinstrap penguins in Antarctica and seagulls in France and the Bering Sea, as well as to Chlamydiifrater spp. isolated from flamingos in France.

Summary: The study found that different probiotics have intestinal anti-inflammatory effects, particularly with slight differences in miRNA expression. Additionally, probiotics improved colitis-associated dysbiosis, although the specific bacterial groups affected varied among the probiotics tested.

Summary: Animals colonized with a defined microbiota, such as ASF mice, provide a valuable experimental system for studying microbiome function. By developing technical and bioinformatic resources, researchers can now perform a detailed analysis of the ASF model, including measurements of bacterial abundance, exploration of genomic and metabolic pathways, transcriptional profiling, and identification of genetic changes.

Summary: This study evaluated the effects of daily intake of LP256 on C. jejuni loads in the ceca and feces of broilers and the changes in the gut microbiota. The results showed that LP256 significantly reduced C. jejuni colonization in the ceca at the beginning of the experiment, but no treatment effect was observed at the end. The colonization dynamics of C. jejuni and the cecal microbiota composition were not affected by LP256 intake.

Summary: The study classified a cohort into four groups and found that there was an increase in Lactobacillus bacterial species after clinical treatments, with a shift from dysbiotic profiles to Lactobacillus-dominated profiles. The microbiota composition before treatment might be related to different disease states, while the composition after treatment could be linked to CIN I, CIN II/III, and SCC.

Summary: The study investigated the effect of tick hormones on the transmission and proliferation of tick-borne bacterial pathogens in tick bodies and ovaries, revealing that 20-hydroxyecdysone (20E) has a regulatory effect on this process. This research contributes to a better understanding of the mechanisms of tick-borne bacterial pathogens.

Summary: This study found that early breast cancer patients have decreased microbial diversity, increased relative abundance of Firmicutes, and decreased relative abundance of Bacteroidetes in their intestinal microbiota compared to healthy controls. Additionally, a trend towards decreased relative abundance of Odoribacter sp., Butyricimonas sp., and Coprococcus sp. was observed in the patients.

Summary: The study explored the prebiotic potential of bread enriched with Polyphenol Rich Fiber (PRF) and found that PRF-enriched bread had positive effects on the host gut model, such as increasing beneficial bacterial groups and producing certain bioactive metabolites. This research not only highlighted the prebiotic role of PRF-enriched bread but also emphasized the potential of the in vitro gut model MICODE in evaluating the functionality of food prototypes as gut microbiota modulators.

Summary: A new Pseudomonas chlororaphis isolate ST9 with potential as a plant probiotic was reported in this study, showing efficient rice root colonization and impact on plant gene expression. Its ability to integrate into the plant resident microbiota and influence plant growth makes it a promising candidate for agricultural applications.
