While the antibiotic potential of some materials used in historical medicine has been demonstrated, empirical tests of entire remedies are scarce. This is an important omission, because the efficacy of “ancientbiotics” could rely on the combined activity of their various … Continue reading
Staphylococcus infections are common in the hospital setting and in the community, but the strains that are prevalent in these two environments differ somewhat. A group in Denmark found that pressure from antibiotic use in hospitals is driving some unexpected evolutionary … Continue reading
To establish infection successfully in the human body, pathogenic bacteria require various iron acquisition mechanisms to obtain iron from host tissues. Continue reading
Staphylococcus aureus is responsible for the vast majority of bacterial skin infections in humans. The propensity for S. aureus to infect skin involves a balance between cutaneous immune defense mechanisms and virulence factors of the pathogen. The tissue architecture of … Continue reading
Gathering and sharing of information is extremely important in human society. Especially in times of war, the difference between victory and defeat can depend on the ability to obtain, encrypt, and share information, and sophisticated systems have been developed for … Continue reading
Methicillin-resistant Staphylococcus aureus (MRSA), first identified in the 1960s, was initially considered to be a nosocomial pathogen (hospital acquired infection). Beginning in the late 20th century, a specific clone of MRSA known as USA300 emerged as a leading cause of … Continue reading
Two new papers in PLoS Pathogens offer new potential strategies against superbugs. Continue reading
The emergence of resistance against most current drugs emphasizes the need to develop new approaches to control bacterial pathogens. Is bacterial fatty acid synthesis a valid target for antibacterial drug discovery? Continue reading
Staphylococcus aureus is an important human pathogen that is found in the nasal passages of approximately 1/3 of the population. The nose serves as a reservoir for spread of this pathogen and predisposes the host to potential infection. Factors contributing to S. aureus nasal colonization are only beginning to be understood.
