Therapeutic Strategies To Counteract Antibiotic Resistance in MRSA Biofilm‐Associated Infections
2021
Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as one of the leading causes of persistent human infections. This pathogen is widespread and is able to colonize asymptomatically about a third of the population, causing moderate to severe infections. It is currently considered the most common cause of nosocomial infections and one of the main causes of death in hospitalized patients. Due to its high morbidity and mortality rate and its ability to resist most antibiotics on the market, it has been termed a “superbug”. Its ability to form biofilms on biotic and abiotic surfaces seems to be the primarily means of MRSA antibiotic resistance and pervasiveness. Importantly, more tha…
Pathogenic microorganisms carried by migratorybirds passing through the territory of the island ofUstica, Sicily (Italy)
2011
Several studies have shown that migratory birds play an important role in the ecology, circulation and dissemination of pathogenic organisms. In October 2006, a health status evaluation was performed on a large population of migratory birds passing through the territory of Ustica (Italy), an island located on the migration route of many species of birds to Africa, and various laboratory tests were conducted. In total, 218 faecal swabs and the internal organs of 21 subjects found dead in nets were collected for bacteriological and virological examination, including avian influenza and Newcastle disease. In addition, 19 pooled fresh faecal samples were collected for mycological examination. T…
Salmonella bongori Provides Insights into the Evolution of the Salmonellae
2011
The genus Salmonella contains two species, S. bongori and S. enterica. Compared to the well-studied S. enterica there is a marked lack of information regarding the genetic makeup and diversity of S. bongori. S. bongori has been found predominantly associated with cold-blooded animals, but it can infect humans. To define the phylogeny of this species, and compare it to S. enterica, we have sequenced 28 isolates representing most of the known diversity of S. bongori. This cross-species analysis allowed us to confidently differentiate ancestral functions from those acquired following speciation, which include both metabolic and virulence-associated capacities. We show that, although S. bongori…
La publicisation des liens entre l’antibiorésistance et l’alimentation dans la presse nationale étatsunienne
2020
Si le problème de la résistance des bactéries aux antibiotiques (antibiorésistance) est depuis longtemps connu dans le domaine scientifique, on assiste aujourd’hui à une phase de reconnaissance politique du problème. L’auteure analyse la publicisation des liens entre l’antibiorésistance et l’alimentation aux États-Unis. Cette étude s’inscrit dans une réflexion pragmatiste de constitution des problèmes publics et s’enrichit des outils issus de l’analyse de discours. Le corpus est constitué d’articles publiés dans deux titres de référence de la presse quotidienne étatsunienne et d’orientation politique différente, The New York Times et The Washington Post, entre 1984 et 2016. Although the sci…
Survey of antibiotic resistance of Pseudomonas isolated from fresh cut red chicory (Cichorium intybus L., Asteraceae)
2018
The present work was carried out to investigate the safety aspects of minimally processed red chicory (Cichorium intybus L., family Asteraceae) regarding the antibiotic resistance of Pseudomonas Migula, 1894 populations (Bacteria Pseudomonadaceae). The Pseudomonas strains tested for their characteristics were previously isolated from experimental monovarietal salads prepared with two different processes, a classic ready-to-eat (RTE) process and a process with entire leaves, and stored under refrigeration (4 °C) up to 15 days from production. Due to their dominance over the microbial community, Pseudomonas strains were better characterised for their undesirable features that might be exerted…
