Antimicrobial activity of prophage endolysins against critical Enterobacteriace...
Gonçalves, Tiago; Marques, Andreia T.; Manageiro, Vera; Tanoeiro, Luis; Vital, Joana S.; Duarte, Aida; Vítor, Jorge M. B.; Caniça, ManuelaEnterobacteriaceae species are part of the 2017 World Health Organization antibiotic-resistant priority pathogens list for development of novel medicines. Multidrug-resistant Klebsiella pneumoniae is an increasing threat to public health and has become a relevant human pathogen involved in life-threatening infections. Phage therapy involves the use of phages or their lytic endolysins as bioagents for the treatm...

Liposomal Delivery of Newly Identified Prophage Lysins in a Pseudomonas aerugin...
Morais, Diana; Tanoeiro, Luis; Marques, Andreia T.; Gonçalves, Tiago; Duarte, Aida; Matos, António Pedro Alves; Vital, Joana S.Pseudomonas aeruginosa is a Gram-negative opportunistic bacterium that presents resistance to several antibiotics, thus, representing a major threat to human and animal health. Phage-derived products, namely lysins, or peptidoglycan-hydrolyzing enzymes, can be an effective weapon against antibiotic-resistant bacteria. Whereas in Gram-positive bacteria, lysis from without is facilitated by the exposed peptidogly...
Biomarker Characterization and Prediction of Virulence and Antibiotic Resistanc...
Vital, Joana S.; Tanoeiro, Luis; Lopes-Oliveira, Ricardo; Vale, Filipa F.The Gram-negative bacterium Helicobacter pylori colonizes c.a. 50% of human stomachs worldwide and is the major risk factor for gastric adenocarcinoma. Its high genetic variability makes it difficult to identify biomarkers of early stages of infection that can reliably predict its outcome. Moreover, the increasing antibiotic resistance found in H. pylori defies therapy, constituting a major human health problem...
16S Genomics for Diagnosing Invasive Bacterial Infection
Vale, Filipa; Tanoeiro, Luis; Marques, Andreia T.Invasive bacterial infections (IBI) are leading causes of global morbidity and mortality. Successful treatment of the patients depends on a rapid and accurate diagnosis. The current golden standard procedure for bacterial identification in clinical context requires bacterial culture and biochemical analysis—a slow, culture-dependent and possible subjective approach, presenting several limitations. Bacteria iden...
Cryptic Prophages Contribution for Campylobacter jejuni and Campylobacter coli ...
Tanoeiro, Luis; Oleastro, Mónica; Nunes, Alexandra; Marques, Andreia T.; Duarte, Sílvia Vaz; Gomes, João Paulo; Matos, António Pedro AlvesCampylobacter coli and C. jejuni, the causing agents of campylobacteriosis, are described to be undergoing introgression events, i.e., the transference of genetic material between different species, with some isolates sharing almost a quarter of its genome. The participation of phages in introgression events and consequent impact on host ecology and evolution remain elusive. Three distinct prophages, named C. j...

Genomic Analysis of Prophages from Klebsiella pneumoniae Clinical Isolates
Marques, Andreia T.; Tanoeiro, Luis; Duarte, Aida; Gonçalves, Luisa; Vítor, Jorge M. B.; Vale, Filipa F.Klebsiella pneumoniae is an increasing threat to public health and represents one of the most concerning pathogens involved in life-threatening infections. The resistant and virulence determinants are coded by mobile genetic elements which can easily spread between bacteria populations and co-evolve with its genomic host. In this study, we present the full genomic sequences, insertion sites and phylogenetic ana...
