Aim: To emphasize the role of non-sulfonamides in the treatment of Nocardia infection and reduce the adverse reactions caused by sulfonamides.
Methods: We retrospectively analyzed a case of cutaneous nocardiosis in an immunocompetent individual. The colonies obtained by staining the pus in the lesion with antacid and culturing the agar plates were identified by flight mass spectrometry. The pathogenic identification showed Nocardia brasiliensis infection and the patient was treated with amoxicillin-clavulanic acid.
Results: After treatment with amoxicillin and clavulanic acid, the ulcer gradually peeled and crusted, leaving dark pigmentation. The patient has finally recovered.
Conclusion: Sulfonamides are the first-line antibacterial agents for years in treatment of nocardiosis but are of great toxicity and side effects. This patient was successfully treated with amoxicillin-clavulanic acid and it provided a reference protocol for patients with sulfonamide-resistant Nocardia or sulfonamides intolerance.

The changing epidemiological profile of invasive infections (IIHi) is noted in the post-vaccination era. The aim of this study was to characterize phenotypically and genotypically invasive (Hi) isolates detected in Tunisian pediatric patients. A retrospective study was conducted in the microbiology laboratory of the Children's Hospital of Tunis over ten years (2013-2023).

The global spread of antimicrobial resistance is one of the most significant challenges of the 21st century. The waterfowl sector is an economically decisive part of the poultry industry, yet it remains under-researched, and its antibiotic usage is less monitored. Our study aimed to determine the antimicrobial susceptibility of avian pathogenic strains, which are still prevalent in ducks and geese, against antibiotics critical for both animal and human health, and to compare these findings with human resistance data.

Widespread use of antibiotics has led to a global increase in resistance. The bacterium is a facultative pathogen that often develops antibiotic resistance and is easily transmitted, not only in animal health but also in public health. Within the poultry sector, domestic fowl is widespread and one of the most dynamically growing sectors, which is why regular, extensive monitoring is crucial.

Article Synopsis
- This study forecasts the consumption of the top ten antibacterial drugs in Germany until 2040, using historical prescription data and ARIMA models.
- The best model for forecasting is a simple random walk with drift (ARIMA(0,1,0)), while short-term predictions show minimal variation among complex models.
- Predictions indicate rising prescriptions for some drugs like amoxicillin, but declines for others, emphasizing the need for proactive healthcare planning to address potential shortages.
Objective: Urinary tract infections (UTIs) are common in neonates. Understanding the changes in the prevalence of common uropathogens is essential for early diagnosis and effective treatment of UTIs. This study aims to identify etiological agents and determine the local antibiotic susceptibility patterns of uropathogens causing UTIs.
