Background: The occurrence of antibiotic resistance and the use of broad-spectrum antibiotics are relatively low in Norway. The national recommendation in febrile neutropenia (FN) is prompt initial therapy with penicillin G plus an aminoglycoside. We sought to evaluate the evidence behind this recommendation.
Methods: We did a literature search in Medline and EMBASE with search terms penicillin, aminoglycoside and febrile neutropenia.
Results: Seven Norwegian studies (six adult and one pediatric) conducted over the last 25 years were identified. They all conclude that penicillin G plus an aminoglycoside are effective and safe initial empiric antibiotic therapy in FN provided the regimen is modified if the clinical response is unsatisfactory. Overall 40-50% of the patients required only penicillin G and an aminoglycoside during their FN episode. The overall fatality rate was similar in the Norwegian and in international studies.
Conclusion: Many countries use a broad-spectrum β-lactam as initial therapy in FN. International experts are sceptic towards the Norwegian recommendations. We discuss the arguments for and against penicillin G plus an aminoglycoside in FN. The main arguments to continue the Norwegian treatment tradition are the satisfactory clinical results and the reason to believe that it contributes to the low levels of antibiotic resistance in Norway.

Antibiotic Prescription Practice and Resistance Patterns of Bacterial Isolates from a Neonatal Intensive Care Unit: A Retrospective Study from Jordan.
Antibiotics (Basel)

Pharmacy and Clinical Pharmacy Directorate, Ministry of Health, Amman 11941, Jordan.
: Neonatal sepsis is a systemic inflammation in neonates caused by bacteria, viruses, or fungi that can progress into severe conditions. In developing countries, neonatal sepsis is a major cause of mortality and a major public health issue with a high prevalence. This study aims to evaluate the antibiotic prescription practice and resistance patterns of bacterial isolates from the neonatal intensive care unit (NICU) at the largest governmental hospital in Amman, Jordan.

Although is a key cause of subclinical mastitis in Danish dairy cows, its sensitivity to antimicrobials remains unexplored. Here, we analyzed sixty isolates derived from 42 dairy cows across six conventional dairy herds in Denmark. Phenotypic resistance was measured by antimicrobial susceptibility testing and minimum inhibitory concentration (MIC) analysis, and genotypic resistance was examined through whole-genome sequencing and identification of antimicrobial resistance genes (ARGs).

Background: is a conditionally pathogenic bacterium that is inherently resistant to polymyxin and tigecycline, largely due to antibiotic resistance genes (ARGs). These ARGs can be horizontally transferred to other bacteria, raising concerns about the Inc plasmid-mediated ARG transmission from , which poses a serious public health threat. This study aims to investigate the presence of Inc plasmid types in pig-derived in Kunming, Yunnan, China.

Medical Microbiology, Leeds Teaching Hospitals Trust, Leeds, UK.
Background: Guidelines suggest treating fully penicillin-susceptible Enterococcus faecalis strains causing infective endocarditis with amoxicillin combined with gentamicin or ceftriaxone, but clinical evidence to support this practice is limited and monotherapy cohorts were excluded from studies. We describe antibiotic treatment, complications, and outcomes in patients with Enterococcus faecalis infective endocarditis, specifically comparing monotherapy versus combination therapy.
Methods: Retrospective analysis of prospectively collected cohort of patients with definite or possible infective endocarditis from 2 English centres between 2006 and 2021.

Background: Cancer is a significant global health issue due to its high incidence and mortality rates. In recent years, the relationship between the human microbiota and cancer has garnered attention across various medical fields. This includes research into the microbial communities that influence cancer development, tumor-associated microorganisms, and the interactions between the microbiome and tumor, collectively referred to as the oncobiome.
