The use of high-performance capillary electrokinetic techniques for the separation, identification, and quantitation of intact microbes represents a new frontier for separation science. In this work, it is demonstrated that pathogens most responsible for urinary tract infections can be distinguished from one another after direct injection of untreated urine. High efficiencies (often exceeding 1000000 plates/m) and short analysis times (< 10 min) are characteristics of this approach. The concentration of the urine matrix appears to be able to cause a small, but definite, change in the electroosmotic flow velocity. This high-efficiency separation-based approach could prove to be invaluable for the diagnosis and tracking of certain diseases. It also could form the basis for a variety of rapid microbial assays.

Although significant progress of clinical strategy has been made in gene editing and cell engineering in immunotherapy, it is now apparent that design and modification in terms of complex signaling pathways and motifs on medical synthetic biology are still full of challenges. Innate immunity, the first line of host defense against pathogens, is critical for anti-pathogens immune response as well as regulating durable and protective T cell-mediated anti-tumor responses. Here, we introduce DSCI (Database of Synthetic Biology Components for Innate Immunity, https://dsci.

Fish disease outbreaks caused by bacterial burdens are responsible for decreasing productivity in aquaculture. Unraveling the molecular mechanisms activated in the gonads after infections is pivotal for enhancing husbandry techniques in fish farms, ensuring disease management, and selecting the most resilience phenotype. The present study, with an important commercial species the European sea bass (Dicentrarchus labrax), an important commercial species in Europe, examined changes in the miRNome and transcriptome 48 h after an intraperitoneal infection with Vibrio anguillarum.

Unlabelled: Coronaviruses have large, positive-sense single-stranded RNA genomes that challenge conventional strategies for mutagenesis. Yeast genetics has been used to manipulate large viral genomes, including those of herpesviruses and coronaviruses. This method, known as transformation-associated recombination (TAR), involves assembling complete viral genomes from dsDNA copies of viral genome fragments via homologous recombination in .

Unlabelled: is well adapted to survive and persist in the infected host, escaping the host's immune response. Since polyamines such as spermine, which are synthesized by infected macrophages, are able to inhibit the growth of , the pathogen needs strategies to cope with these toxic metabolites. The actinomycete , a close relative of makes use of a gamma-glutamylation pathway to functionally neutralize spermine.

Purpose Of Review: Antimicrobial resistance is an escalating public health threat in Africa, and an awareness of the devastating impact on children is growing. This review highlights the prevalence and patterns of antimicrobial resistance among children in Africa, focusing on pathogens responsible for bloodstream infections, community-acquired pneumonia, bacterial meningitis, neonatal infections, diarrhea and malaria. Current strategies to tackle antimicrobial resistance in pediatric populations are discussed.
