Are sHV-type extended-spectrum beta-lactamase ( ESBL ) encoded in related plasmids from enterobacteria clinical isolates from Mexico?
The dissemination of cephalosporin resistance was due to related plasmids carrying the ESBL genes.
The localization of STEVOR proteins to the merozoite surface and the rhoptries together with its prevalence as a released component in the invading merozoite suggest a role of these antigens in adhesion and/or immune evasion in the erythrocyte invasion process. These observations would also justify STEVORs for undergoing antigenic variation. Even though a role in erythrocyte invasion remains speculative, an association of members of the STEVOR protein family with invasion-related events has been shown.
