Purpose: To examine whether the epidemiology of bacteraemia caused by methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA) differed in children aged <1 year and in comparison to older age groups.
Methodology: English mandatory MRSA and MSSA surveillance data from 2006 and 2011, respectively, were collected. Epidemiological information was descriptively analysed in relation to methicillin susceptibility and patient age. Ninety-five percent confidence intervals (CIs) are reported.Results/Key findings. The average incidence rate of MSSA and MRSA bacteraemia in <1-year-olds was 60.2 and 4.8 episodes per 100 000 population per year, respectively. Of the cases of MSSA bacteraemia in children aged <1 year, 47.5 % (95 % CI: 45.1-50.0; n=760/1 599) were in neonates. With increasing age up to one year, more MSSA bacteraemias were detected ≥7 days after admission, ranging from 0 % (95 % CI: 0-2.5 %) in 0-2-day-olds to 68.4 % (95 % CI: 64.0-72.5 %; 333/487) in 8-28-day-olds and 50.5 % (95 % CI: 47.1-54.0 %; 423/837) in 29 day-1-year-olds, a higher proportion than in older children but similar to MRSA bacteraemia. Amongst <1-year-olds with MSSA bacteraemia, the underlying source was most commonly recorded as intravascular devices [34.4 % (95 %, CI: 30.5-38.6 %); n=190/552] whilst in older age groups this declined. A similar trend was observed for MRSA bacteraemia.
Conclusions: Our analysis indicates that S. aureus bacteraemia in <1-year-olds is primarily healthcare-associated, unlike MSSA bacteraemia in older age groups. Paediatric-specific interventions targeted at the healthcare setting, such as neonatal unit-specific care bundles and paediatric device-specific strategies, are required.

Central nervous system (CNS) infections caused by SARS-CoV-2 are uncommon. This case report describes the clinical progression of a 92-year-old female who developed a persistent neuroinfection associated with SARS-CoV-2. The patient initially presented with progressive fatigue, catarrhal symptoms, and a fever (38.

As natural predators of bacteria, tailed bacteriophages can be used in biocontrol applications, including antimicrobial therapy. Also, phage lysis is a detrimental factor in technological processes based on bacterial growth and metabolism. The spectrum of bacteria bacteriophages interact with is known as the host range.

: Community-acquired methicillin-resistant (CA-MRSA) greatly complicates the treatment of skin and soft tissue infections (SSTI). It was previously found that subcutaneous (SQ) treatment with the mononuclear phagocyte (MP)-selective activator complements peptide-derived immunostimulant-02 (CPDI-02; formerly EP67) and increases prophylaxis of outbred CD-1 mice against SQ infection with CA-MRSA. Here, we determined if treatment with CPDI-02 also increases curative protection.

Background/objectives: Biofilm-associated infections, particularly those involving Candida auris and Staphylococcus aureus, pose significant challenges in clinical settings due to their resilience and resistance to conventional treatments. This study aimed to synthesize novel triazole derivatives containing a piperazine ring via click chemistry and evaluate their efficacy in disrupting biofilms formed by these pathogens.
Methods: Triazole derivatives were synthesized using click chemistry techniques.

Pathogen bacteria appear and survive on various surfaces made of steel or glass. The existence of these bacteria in different forms causes significant problems in healthcare facilities and society. Therefore, the surface engineering of highly potent antimicrobial coatings is highly important in the 21st century, a period that began with a series of epidemics.
