Staphylococcus nasal colonization in three species of non-human primates.

Bacterial nasal colonization is common in many mammals and Staphylococcus represents the main pathogen isolated. Staphylococcus nasal carriage in humans constitutes a risk factor for Staphylococcus infections pointing out the need for animal experimentation for nasal colonization studies, especially for vaccine development. A limitation in addressing this hypothesis has been a lack of appropriate animal model.

Generation and Characterization of Murine Monoclonal Antibodies anti-PBP2a of Methicillin-resistant Staphylococcus aureus.

Methicillin-resistant Staphylococcus aureus (MRSA) is a multidrug-resistant bacterium that causes serious infections worldwide. This pathogen is resistant to all beta lactam antibiotics due the presence of PBP2a, a transpeptidase enzyme that presents very low beta-lactam affinity. Here we report the generation and characterization of mouse monoclonal antibodies to PBP2a of MRSA strains.
