Summary: Anthropogenic disturbance on natural ecosystems is increasing, affecting all components of the ecosystems. A metacommunity framework is needed to understand the response of different biocoenosis types to human disturbance. Through advanced molecular techniques, sediment communities of Fungi, Bacteria, and Archaea in Italian show caves were investigated to unravel the effects of tourism on their diversity and identify changes in the driving forces of community composition. The study showed that cave tourism directly affects the community of Bacteria and indirectly influences Fungi and Archaea.

Summary: The study focused on analyzing the secretion of relevant antimicrobial peptides and proteins (AMPs), especially RNase 7, human beta-defensin-2 (hBD-2), and the S-100 protein psoriasin (S100A7), in patients with confirmed tinea pedis. It was found that the AMP concentrations were significantly higher in the lesional skin of tinea pedis patients compared to non-lesional skin and healthy skin of controls, with elevated concentrations of hBD-2 and psoriasin.

Summary: This study aimed to evaluate if diet can change the bacteria on the skin of healthy dogs. The results showed an increase in bacterium types and a change in their relative quantity when dogs were fed a fresh dog food compared to dry pet foods. This study shed light on how different pet foods impact the skin microbiome.

Summary: Research indicates a wide range of bacterial and fungal microbiomes present in tobacco products, with some known human pathogens and others as potential opportunistic pathogens. Future studies should focus on the viability of these microorganisms and their potential transfer to the respiratory tract of users, potentially impacting their health.

Summary: Recent studies utilizing modern technologies have identified a larger number of bacterial and fungal organisms in the skin microbiome of cats compared to culture-based studies. This expansion of knowledge provides a better understanding of how microbial communities are affected by changes in cat skin health and offers potential areas for research in correcting dysbiosis and improving feline skin health.

Summary: Aberrant function of plant circadian clock can lead to altered rhythmicity of rhizosphere bacteria and fungi, resulting in changes in the composition of rhizosphere microbiome with potential consequences for plant health.

Summary: Foliar endophytic bacteria and fungi in parasitic and non-parasitic plants were found to be diverse, dominated by generalist taxa, but highly similar across all studied species. Despite contrasting leaf tissue chemistry, the trophic mode of parasitic plants did not systematically affect the diversity, composition, or predicted biogeochemical function of the endophytic microbiomes under field conditions. Parasitic plants may possess mechanisms to regulate the extent of colonization by endophytic fungi.

Summary: This study investigates the responses of soil microbial communities in drylands to environmental stress factors. The results show that bacterial and fungal diversity and community similarity have different sensitivities to environmental stress, with mean annual precipitation being the most important factor. Dominant subcommunities of bacteria and fungi are more sensitive to stress than non-dominant subcommunities. Additionally, certain bacterial and fungal taxa are found to be sensitive to environmental stress and are correlated with carbon and nitrogen cycling-related genes.

Summary: This study evaluated the burden of tinea pedis in underrepresented groups in the United States using the AoU research program. The results showed that Black and Hispanic participants had a higher prevalence of tinea pedis, and underrepresented groups defined by age, LGBTQ status, education level, income, and physical disability also had higher rates of tinea pedis.

Summary: This study compared the relationship between airway microbiota and immune markers in obese and nonobese individuals with and without mild-moderate asthma. The results showed that obesity itself is associated with an altered sputum microbiome, and there are distinct differences in the airway microbiota and immune marker relationships in obese asthma. These differences may affect the mechanisms and outcomes of obese asthma.

Summary: In this study, the bacterial and fungal communities in the rumen of pastured yaks of different ages were analyzed using full-length sequencing. The results showed that the rumen microflora of Zhongdian yaks changed gradually from 5 to 180 days after birth and tended to stabilize at 2 years of age. The rumen of adult yaks was the most suitable for the growth and reproduction of most bacteria. At 90 days of age, the yak rumen was the most suitable for the growth and reproduction of most fungi, and 90 days of age could be a cut-off point for the distribution of fungal communities. The study provided insights into the dynamic changes of dominant microflora with yak growth.

Summary: Multiple probiotics have protective effects against different types of liver injury, and intestinal microbes may be associated with the immune improvement effect of probiotics in the treated cohorts. The composition of bacterial and fungal microbiome differs in rats with different cytokine profiles. Certain microbes are associated with specific cytokine profiles and have a significant influence on the immunity improvement effect of probiotics. These identified intestinal microbes could potentially serve as microbial biomarkers for assessing the immune status of probiotics-treated cohorts.

Summary: Deadwood plays a crucial role in forest ecology, and the degradation and carbon assimilation of deadwood are carried out by fungi and bacteria. This study investigated the abundance and distribution of microbial taxa in dead spruce logs and the soil below over a 50-year period. The results showed differences in microbial diversity and relative abundance between the samples from 1974 and 2014, with certain taxa being more predominant in each time period.

Summary: This study used the millipede Cherokia georgiana georgiana as a model and metabarcoding approach to investigate the impacts of millipedes on soil microbial communities with varying nitrogen levels. The research found that millipedes strongly alter soil communities, but nitrogen levels did not impact millipede gut communities. Additionally, the study provided evidence that millipede gut communities are mainly derived from soils rather than leaf litter.
