AI Article Synopsis
- The study investigates how oral doxycycline affects the gut microbiota of mice, focusing on the 16S rRNA gene sequencing of fecal samples.
- Doxycycline treatment led to a notable reduction in microbial richness and diversity, with an increase in Bacteroides species in treated mice compared to controls.
- The observed changes in gut microbiota remained even after a week without treatment, indicating that doxycycline can cause lasting dysbiosis, which should be taken into account in related animal model research.
Article Abstract
Objective: This study aims to demonstrate the effect of oral doxycycline on fecal microbiota of mice. Doxycycline is a common effector for control of gene expression using the tet-inducible system in transgenic mice. The effect of oral doxycycline on murine gut microbiota has not been reported. We evaluated the effect of doxycycline treatment by sequencing the V4 hypervariable region of the 16S rRNA gene from fecal samples collected during a 4 week course of treatment at a dose of 2 mg/ml in the drinking water.
Results: The fecal microbiota of treated animals were distinct from control animals; the decreased richness and diversity were characterized primarily by Bacteroides sp. enrichment. These effects persisted when the treatment was temporarily discontinued for 1 week. These data suggest that doxycycline treatment can induce significant dysbiosis, and its effects should be considered when used in animal models that are or maybe sensitive to perturbation of the gut microbiota.

Background: Photodynamic therapy (PDT) is beneficial for managing rosacea, and chlorin e6 derivative-mediated photodynamic therapy (STBF-PDT) has demonstrated efficacy in reducing acne lesions with mild adverse reactions.
Objectives: This study aimed to assess the effectiveness and safety of STBF-PDT for the treatment of moderate-to-severe rosacea.
Methods: In this prospective, randomised, evaluator-blind controlled study, patients with moderate-to-severe rosacea were assigned to receive up to six STBF-PDT sessions or 100 mg of doxycycline daily for eight weeks, followed by a 24-week follow-up.

A 30-year-old male patient with symptomatic Mycoplasma genitalium urethritis failed treatment with oral azithromycin, 2-stage doxycycline-moxifloxacin, and minocycline. Molecular testing confirmed the presence of macrolide resistance mutations. Treatment with oral tinidazole 2 g daily for 7 days resulted in clinical and microbiologic cure.

Objective: This paper evaluates the accuracy of C-reactive protein (CRP), leukocyte count, and neutrophil-to-lymphocyte ratio (NLR) for diagnosing tubo-ovarian abscess (TOA) and assessing the cost-effectiveness of different treatment regimens for pelvic inflammatory disease (PID), with and without TOA.
Method: A retrospective cohort study was conducted between January 1, 2003, and December 30, 2021, including women aged 13-80 years diagnosed with PID. The analysis focused on the incremental cost-effectiveness ratio of different treatment regimens.
