The molecular characterization of 218 GBS isolates recovered from neonatal invasive infections in Portugal in 2005–2015 revealed the existence of a small number of genetically distinct lineages that were present over a significant time-span. Serotypes III and Ia were dominant in the population, together accounting for >80% of the isolates. Clonal complex 17 included 50% of all isolates, highlighting the importance of the hypervirulent genetic lineage represented by serotype III ST17/rib/PI-1+PI-2b. Serotype Ia was represented mainly by ST23, previously reported as dominant among invasive disease in non-pregnant adults in Portugal, but also by ST24, showing an increased frequency among late-onset disease. Overall erythromycin resistance was 16%, increasing during the study period (p < 0.001). Macrolide resistance was overrepresented among CC1 and CC19 isolates (p < 0.001 and p = 0.008, respectively). While representatives of the hypervirulent CC17 lineage were mostly susceptible to macrolides, we identified for the first time in Europe a recently emerging sublineage characterized by the loss of PI-1 (CC17/PI-2b), simultaneously resistant to macrolides, lincosamides, and tetracycline, also exhibiting high-level resistance to streptomycin and kanamycin. The stability and dominance of CC17 among neonatal invasive infections in the past decades indicates that it is extremely well adapted to its niche; however emerging resistance in this genetic background may have significant implications for the prevention and management of GBS disease.

Fashion industry is the second most polluting industry in the world representing a 2 trillion dollars and growing valuation (Pal, 2017). This dual context makes its challenges hard to address. From one side, fashion design education and practice systems have been perpetuating an industrial-focused approach which relies mostly in the economic improvement through fast cycles of product development (Pal, 2017). On the other side, fashion industry has also been closed to either multidisciplinary and transdisciplinary initiatives outside the scope of the artistic disciplines. Therefore, innovative approaches are needed to solve fashion industrial challenges. One of the most promising fields to tackle fashion current environment and technological problems is microbiology (Mazzoto et al., 2021). During the past 50 years, microbiology has played a vital role in solving human grand challenges in health, agriculture, food, and waste management sectors, and it also represents an opportunity for fashion industry as well. Microbiology biotechnological potential for the fashion industry relies mostly on the improvement of toxic waste bioremediation and the development of novel biomaterials and biomolecules. Moreover, the emergent field of synthetic biology is expanding the tools and approaches available, and they can already be seen in the development of engineered living materials that have functional properties (Mazzoto et al., 2021). Despite the urgent need for change, there is still a long way until a more sustainable fashion industry is achieved. Therefore, microbiological research and innovation need maturation to be able to scale-up and reach a global impact for tackling fashion industrial problems.

Background: The fungal component of the gut microbiome has been underrepresented in most gut microbiome studies. While next-generation sequencing (NGS) approaches have been used to assess the diversity and role of the gut mycobiome, differences in experimental design and downstream analyses may induce bias and differential outcomes. This study assessed the capacity of nanopore sequencing to retrieve the microbial profile and relative abundance of a mock fungal community comprised of Candida glabrata, Meyerozyma guilliermondii, Pichia kudriavzevii, Clavispora lusitaniae and Candida parapsilosis. Methods: The approach was implemented using the MinION system and involved the analysis of sequencing libraries made from equimolar mixtures of the PCR-amplified internal transcriber spacer genomic regions of the target species. Results: Nanopore sequencing successfully retrieved the composition of the fungal mock community in terms of the different taxa present. However, the approach was unable to correctly assess the expected relative abundances of each species in the same community, showing some yet undetermined bias that may be related to the size of the respective target DNA fragments. Clavispora lusitaniae was consistently overrepresented in the mixtures, while C. glabrata was underrepresented. The remaining three species showed relative abundances more aligned with the expected values of an equimolar mixture. Conclusions: Although not yielding the expected results for the relative abundances, the values obtained from independent sequencing runs were similar for all species, suggesting a good reliability but questionable accuracy in this sequencing approach.

Disorders associated with substance abuse are a major public health crisis with few treatment options. According to World Health Organization (WHO) ethanol is the most widely used drug in the world, and it represents a risk factor for the advent of disease, disability, and eventually death. Foetal Alcoholic Spectrum Disorders (FASD) is a diagnostic term to describe the range of effects that can occur in an individual whose mother drank alcohol during pregnancy. These effects encompass both physical, mental, behavioural and further lifelong disabilities. Besides, ethanol can harm the gut microbiota. Gut microbiome is firstly acquired from the mother and it is crucial for intestinal homeostasis during hosts&rsquo; lifetime. It is responsible for producing metabolites that benefits and protects the host from harm microbial colonization. Knowledge about the interactions between human gut microbes and the developing nervous system is still scarce. Nevertheless, animal models have shown that gut bacteria and microbial metabolites are strongly associated with Central Nervous System (CNS) homeostasis. Endotoxins such as Lipopolysaccharides (LPS) are hypothesized to have a major role in neurodegeneration, however, conclusions must be taken with care due to differences in sensitivity between humans and mice. In this review we focus on the role of gut microbiota on the neurodevelopment of mice when ethanol consumption is one of the major stressors during prenatal period. We detail the range of the endotoxin hypothesis in describing endotoxins&rsquo; contribution to neurodegeneration and the influence that kynurenine pathway has on the process.

From the merge of arts and crafts towards a practice for mass production of desirability, consumption and product development in a capitalist economy of scale, design has lost its natural ability of problem comprehension and tension alleviation. The modern world needs the creativity, flexibility, and responsiveness embedded into design practices, mostly when a behavioural change, either individual or organizational, is intended. Still, the informality nature of the field is creating a gap between the study, research, and industrial design practice. Here it is presented the Biology of Creativity Model (BoC) which is a design-by-analogy method that promotes an empowered design practice through analysis of mostly biology reference texts for enhanced creativity and innovation performance in a diverse array of contexts.

The gut microbiome plays a vital role in host homeostasis and understanding of its biology is essential for a better comprehension of the etiology of disorders such as foetal alcohol spectrum disorders. Here we assessed the effectiveness of targeted and untargeted (metagenomic) nanopore sequencing approaches to profile the gut microbiota of infant mice exposed to ethanol in utero. DNA extracts from the gut content of 12 infant mice exposed to ethanol in utero were analysed using one untargeted and two targeted (full-length 16S rRNA gene and the 16S-ITS-23S region of the ribosomal RNA operon) nanopore sequencing approaches. The targeting of the full-length 16S rRNA gene provided the most comprehensive analysis of the mouse gut microbiota. The differences in diversity between approaches were accounted by the sequencing target (p-value < 0.001). Faecalibaculum rodentium and Duncaniella sp. were the two most prevalent taxa detected using targeted sequencing approaches, while bacterial taxa were more evenly represented when using the metagenomic approach. Full-length 16S rRNA gene nanopore sequencing provides the most discriminatory microbiota compositional analysis of mice faecal samples. However, using nanopore sequencing approaches targeting the metagenome or different taxonomically-informative DNA region appears to introduce significant target-related biases.

The gut microbiome plays a vital role in host homeostasis and understanding of its biology is essential for a better comprehension of the etiology of disorders such as Foetal Alcohol Spectrum Disorder. Foetal Alcohol Spectrum Disorder represents a cluster of abnormalities including growth deficiencies and neurological impairments, which are not easily diagnosed nor treated. Here the effect of ethanol exposure in utero on the gut microbial profiles of 16 infant mice (nine exposed in utero and seven non-exposed) was assessed by targeted nanopore sequencing and Illumina sequencing approaches. The nanopore sequencing was implemented using MinION system targeting PCR-amplified amplicons made from the full-length 16S rRNA gene. The Illumina sequencing was performed using Miseq system targeting the V3-V4 region of the 16S rRNA gene. Ethanol exposure did not affect the microbial profiles. Several low prevalent taxa, like Akkermansia muciniphila, were detected but further studies must be performed to detail the effect of ethanol exposure to these taxa since no clear pattern was detected throughout this study.
