Cyanobacteria represent one of the most common members sponge-associated bacterial community and are abundant symbionts coral reef ecosystems. In this study we used Transmission Electron Microscopy (TEM) molecular techniques (16S rRNA gene marker) to characterize spatial distribution cyanobionts in widely dispersed marine intertidal sponge Hymeniacidon perlevis along coast Portugal (Atlantic Ocean). We described new associated cyanobacterial morphotypes (Xenococcus-like) further observed...
Sponges are ancient metazoans that host diverse and complex microbial communities. Sponge-associated diversity has been studied from wide oceans across the globe, particularly in subtidal regions, but communities intertidal sponges have remained mostly unexplored. Here we used pyrosequencing to characterize 12 different co-occurring marine sponge species sampled Atlantic coast, revealing a total of 686 operational taxonomic units (OTUs) at 97% sequence similarity. Taxonomic assignment 16S...
The diversity and specificity of microbial communities in marine environments is a key aspect the ecology evolution both eukaryotic hosts their associated prokaryotes. Marine sponges harbor phylogenetically diverse complex lineages. Here, we investigated sponge bacterial community distribution patterns microbes three sympatric intertidal demosponges, Hymeniacidon perlevis, Ophlitaspongia papilla Polymastia penicillus, from Atlantic coast Portugal using classical isolation techniques 16S rRNA...
Sponges harbor a complex consortium of microbial communities living in symbiotic relationship benefiting each other through the integration metabolites. The mechanisms influencing successful association with sponge partner are yet to be fully understood. Here, we sequenced genome Pseudovibrio sp. POLY-S9 strain isolated from intertidal marine Polymastia penicillus sampled Atlantic coast Portugal identify genomic features favoring relationship. draft revealed an exceptionally large size 6.6...
Bacteria belonging to the genus Pseudovibrio have been frequently found in association with a wide variety of marine eukaryotic invertebrate hosts, indicative their versatile and symbiotic lifestyle. A recent comparison sponge-associated genomes has shed light on mechanisms influencing successful sponges. In contrast, genomic architecture bacteria associated other hosts received less attention. Here, we performed genus-wide comparative analyses 18 isolated from sponges, coral, tunicates,...
Microcystins (MCs) are frequently detected in cyanobacterial bloom-impacted waterbodies and introduced into agroecosystems via irrigation water. They widely known as phytotoxic cyanotoxins, which impair the growth physiological functions of crop plants. However, their impact on plant-associated microbiota is scarcely tackled poorly understood. Therefore, we aimed to investigate effect MCs microbiota-inhabiting bulk soil (BS), root adhering (RAS), tissue (RT) Vicia faba when exposed 100 μg...
The most recently described bacterial members of the genus Endozoicomonas have been found in association with a wide variety marine invertebrates. Despite their ubiquity host holobiont, limited information is available on molecular genomic signatures symbiotic sponges. Here, we generated draft genome sp. OPT23 isolated from intertidal sponge Ophlitaspongia papilla and performed comprehensive comparative genomics analyses. Genome-specific analysis metabolic pathway comparison revealed...
The bacterial members of the genus Shewanella are widely distributed and inhabit both freshwater marine environments. Some have gained considerable attention due to its ability survive in redox-stratified However, a gap knowledge exists on key genomic features sponge-associated sp. involving successful host-bacteria interaction, as sponge-symbiotic largely underrepresented public repositories. With aim identifying signatures sponge-Shewanella association, we generated high-quality genome...
Green consumption refers to consumer decision-making that prioritizes the environmental impacts of purchases. The aim current research was identify factors influence consumers purchase sustainable palm oil (SPO) products. Semi-structured interviews were conducted with 13 adult residents Australia, transcribed, and subjected framework analysis, sub-themes classified under main themes capability, opportunity, motivation. While several emerged, those barriers unique SPO purchasing behavior...
Abstract Sponges are important components of intertidal marine communities. There is a lack information about sponge diversity in the western coast Portugal (North-east Atlantic). In present work we identified most common sponges Portugal, and made comprehensive list species described so far for this region. belonging to Classes Calcarea Demospongiae were identified, former class first time at these locations. sponges, all sampling We used an integrative approach identification, using both...

Tuberculous meningitis (TBM) is caused by the dissemination of Mycobacterium tuberculosis (MTB) from primary site infection to central nervous system. However, bacterial factors associated with pathogenesis TBM remain unclear. This study employed transcriptomic and proteomic methods comprehensively analyze changes in genes proteins their pathways MTB strains isolated cerebrospinal fluid (CSF) sputum pulmonary TB (PTB) cases. Five were subjected OMICs (transcriptomic proteomic) analysis....
Antibiotics like colistin can save patients infected with carbapenem-resistant Pseudomonas aeruginosa. However, succumb to such infections even if they undergo therapy. This prompted us investigate the probable antimicrobial resistance mechanisms and virulence determinants involved in colistin- P. aeruginosa (CCRPA). Of 448 clinical strains, 19 isolates were resistant both carbapenem. Carbapenemases efflux pump encoding genes assessed by multiplex PCR qPCR, respectively. blaVIM was detected...
