Characterization of tetracycline and methicillin resistant Staphylococcus aureus strains in a Spanish hospital: is livestock-contact a risk factor in infections caused by MRSA CC398?

Unlabelled: Tetracycline-resistance (Tet(R)) has been postulated as a marker of the livestock-associated methicillin-resistant Staphylococcus aureus (MRSA) lineage CC398.

Objectives Of The Study: to determine the spa-types and assigned MLST clonal complexes (CCs) among all 98 MRSA-Tet(R) strains recovered during 2011-2012 (from different patients) in a Spanish Hospital, analyzing the possible correlation with livestock-contact of the patients. All 98 strains were assigned to 9 CCs: CC398 (60.

[Kingella kingae pediatric septic arthritis].

Kingella kingae is a bacterium that colonizes the upper respiratory tract. Despite its low pathogenicity in this location, previous respiratory pathological processes may favor its systemic spread causing bone and joint infections, mainly in children under five years. It can be considered an emerging pathogen in osteoarticular infection in pediatric patients.
