Abstract:

Dental caries are one of the leading infectious microbial diseases globally. Streptococcus species are the predominant causative agents for the formation of dental caries. Various antibiotics have been reported for the treatment of dental caries in humans. However, owing to the increasing evidence of microbial resistance, there is a need to develop safe and effective alternative treatments for infections. Traditional medicinal plants and their bioactive products have been explored worldwide for the treatment of various diseases and infections. These plants have great potential for creating nov

Melia azedarach L. belongs to one of the most versatile medicinal plants family meliaceae (mahogany) which has great attraction for researchers. The plant was selected for research because it was one of the least explored members. The presence of saponin, alkaloids, tannins and flavonoids in the leaves extracts of plant indicated its medicinal value. These compounds have pharmacological effects against cancer, viral and malarial infections that are one of the main causes of deaths.

Thus, this review provides an overview of all recently published studies on the development

Abstract:

Staphylococcus aureus is a major public health concern. Methicillin resistant Staphylococcus aureus is not only resistant to methicillin and other β-lactam antibacterial agents but also to other antibacterial agents. Therefore, new agents are needed to treat Methicillin Resistant Staphylococcus aureus (MRSA). The main aim of the present research was to study the antibacterial activity of four plants extract against clinical isolates of Staphylococcus aureus at the purpose of overcoming its infection.

Abstract:

India is found to be a country with rich biodiversity and enormous treasure of herbal plants and consequently called as medicinal garden of the world. Plants are the richest source of natural antimicrobial agents. In recent years drug resistance to human pathogenic bacteria has been commonly reported from all over the world. Therefore, there is a need to develop alternative antimicrobial drugs for the treatment of infectious diseases; one approach is to screen local medicinal plants for possible antimicrobial properties. The present study was designed to evaluate the antimicrobial efficacy of
