Mechanism of Action of Essential Oils and their Major Components
Abstract: The essential oil of lemongrass, palm rosa and eucalyptus were found to be good antimicrobial agents. To a large extent the results suggest their potential use as chemotherapeutic agents, food preserving agents, and disinfectants. However before considering these compounds as chemotherapeutic agents against human/animal diseases, it is important to study their cytotoxic and mutagenic effects. Studies were then carried to investigate the probable mechanism by which these compounds act against …

Virulence Factors in pathogens :mechanisms of infection & disease progression
Abstract: Pathogens, like bacteria, viruses, fungi, and parasites, have evolved specialized tools – known as virulence factors – that help them infect hosts, escape the immune system, and cause disease. These factors play a key role in determining how severe an infection becomes, how quickly it spreads, and how the body responds. Some pathogens use adhesins to stick to host cells, while others produce toxins that damage tissues or disrupt normal …
