Coevolutionary phage training expands phage host range: Driven by tail fiber mutations in Pseudomonas aeruginosa lytic phage?

The rise of antibiotic-resistant bacteria, particularly multidrug-resistant Pseudomonas aeruginosa (P. aeruginosa), represents a critical challenge to global health security. Bacteriophages, with their ability to target and lyse specific bacterial pathogens, present a promising alternative through phage therapy.

Exploration of the feasibility of clinical application of phage treatment for multidrug-resistant -induced pulmonary infection.

() commonly induces refractory infection due to its multidrug-resistant nature. To date, there have been no reports on the application of phage treatment for infection. This study was conducted to explore the feasibility of phage application in treating refractory infection by collaborating with a 59-year-old male patient with a pulmonary infection of multidrug-resistant Our experiments included three domains: ) selection of the appropriate phage, ) verification of the efficacy and safety of the selected phage, ) confirmation of phage-bacteria interactions.

Pathogenetic characterization of a strain isolated from an infant.

Purpose: To explore the clinical characteristics of bloodstream infection in an infant and characterize the phenotype and genotype of the isolated strains, as well as seek suitable infection models for assessing virulence.

Methods: Clinical data was collected from an infant patient diagnosed with bloodstream infection. Metagenomic sequencing was performed on the isolated blood sample.

Distribution of drug-resistant genes in alveolar lavage fluid from patients with psittacosis and traceability analysis of causative organisms.

Background: is a small bacterium often found in birds, including poultry, and domesticated mammals, which causes psittacosis (or parrot fever) in humans. Different strains of respond variably to antibiotics, suggesting a possible risk of antibiotic resistance. In general, different genotypes of have relatively stable hosts and different pathogenicity.

Epidemiological and genomic analyses of human isolates of between 2005 and 2021 in Shenzhen, China.

() is an important food-borne zoonotic pathogen that causes swine streptococcosis, which threatens human health and brings economic loss to the swine industry. Three-quarters of human infections are caused by serotype 2. A retrospective analysis of human cases in Shenzhen, a megacity in China, with high pork consumption, between 2005 and 2021 was conducted to understand its genomic epidemiology, pathogen virulence, and drug resistance characteristics.
