Enterobacter supplement and ambient conditions determine the performance of sterile male Mediterranean fruit flies

Physiological Entomology, EarlyView.
Partial replacement of Brewer's yeast (protein source) with inactivated Enterobacter biomass during larval development enhanced mating competitiveness of sterile VIENNA 8 GSS males under outdoor field‐cage conditions. Sterile male mating performance was season‐dependent, with highest competitiveness in spring, intermediate in autumn and the lowest ...

Antibiotic‐mediated immune modulation in periodontitis

Periodontology 2000, EarlyView.
Abstract Periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth. Although initiated by dysbiotic microbial communities, its progression is largely driven by the host's uncontrolled inflammatory response. While antibiotics have conventionally been employed in periodontitis therapy for their antimicrobial ...
