RESUMEN
Periodontitis is an inflammatory disease caused by microbial infections of the gum. At an advanced stage, periodontitis can even destroy the alveolar bone. Fusobacterium nucleatum, Prevotella intermedia, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Capnocytophaga gingivalis, and Pr. nigrescens are the major pathogens in periodontitis. Scaling and root planning are used together with local or systemic antibiotics to treat periodontitis. The difficulty in complete eradication of periodontal pathogens frequently leads to the relapse of the disease. As not many new antibiotics are available in the market, many researchers are now focusing on developing alternative strategies against periodontal microbes. This review provides an overview of the possible use of bacteriophages, lysins, honey, plant extracts, metallic salts, nanoparticles, and vaccines as alternative therapeutic agents against periodontal infections. The information provided here could help in designing alternative therapeutics for the treatment of periodontal infections.

Pseudomonas aeruginosa is a leading cause of nosocomial infections and is responsible for â¼10% of all hospital-acquired infections worldwide. It continues to pose a therapeutic challenge because of the high rate of morbidity and mortality associated with it and the possibility of development of drug resistance during therapy. Standard antibiotic regimes against P. aeruginosa are increasingly becoming ineffective due to the rise in drug resistance. With the scope for developing new antibiotics being limited, alternative treatment options are gaining more and more attention. A number of recent studies reported complementary and alternative treatment options to combat P. aeruginosa infections. Quorum sensing inhibitors, phages, probiotics, anti-microbial peptides, vaccine antigens and antimicrobial nanoparticles have the potential to act against drug resistant strains. Unfortunately, most studies considering alternative treatment options are still confined in the pre-clinical stages, although some of these findings have tremendous potential to be turned into valuable therapeutics. This review is intended to raise awareness of several novel approaches that can be considered further for combating drug resistant P. aeruginosa infections.
