Cancer chemotherapy compromises the patient’s oral health through dysbiosis of oral microbiota and increases the prevalence of dental cavities, gingivitis, oral mucositis, and xerostomia. This research aimed to evaluate the effect of a common chemotherapeutic agent, Fluorouracil (5-FU), on certain microorganisms that are common within the oral cavity. Varying concentrations (50 μM, 75 μM and 100μM) of 5-FU were used to simulate the dosage that reaches the oral cavity after intravenous delivery. The microorganisms tested were Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus faecalis, Streptococcus mutans, Lactobacillus rhamnosus and Streptococcus salivarius. These are some of the most common ones found in the …

The oral microbiome is an important predictor of health and disease. We recently reported significant yet modest effects of HIV under highly active antiretroviral therapy (ART) on the oral microbiome (bacterial and fungal) in a large cohort of HIV-positive (HIV+) and matched HIV-negative (HIV-) individuals. As it was unclear whether ART added to or masked further effects of HIV on the oral microbiome, the present study aimed to analyze the effects of HIV and ART independently, which also included HIV- subjects on preexposure prophylaxis (PrEP) therapy. Cross-sectional analyses of the effect of HIV devoid of ART (HIV+ ART- versus matched …
