Panton-Valentine leukocidin-positive methicillin-resistant Staphylococcus aureus infections in children with cancer.

13 Dec 2009 BACKGROUND: New strains of methicillin-resistant Staphylococcus aureus (MRSA) which frequently carry the Panton-Valentine leukocidin (PVL) genes have been recognized to cause invasive infections in otherwise healthy children and adults. However, the ... Read more...

Anopheles gambiae alkaline phosphatase is a functional receptor of Bacillus thuringiensis jegathesan Cry11Ba toxin.

18 Oct 2009 Alkaline phosphatases (ALPs, EC 3.1.3.1) isolated from lepidopteran and dipteran species are identified as receptors for Cry1Ac and Cry11Aa toxins, respectively [Jurat-Fuentes, J. L., and Adang, M. J. (2004) Eur. J. Biochem. 7, 3127-3135; Fernandez, ... Read more...

The Staphylococcus aureus lineage-specific markers collagen adhesin and toxic shock syndrome toxin 1 distinguish multilocus sequence typing clonal complexes within spa clonal complexes.

29 Sep 2009 Spa typing/based upon repeat pattern (BURP) sometimes cannot differentiate multilocus sequence typing (MLST) clonal complexes (CCs) within spa-CCs. It has been observed previously that virulence factors, such as collagen adhesin (CNA) and toxic ... Read more...
