Toxin-neutralizing Abs are associated with improved T cell function following recovery from Staphylococcus aureus infection.

BACKGROUNDT cell responses are impaired in Staphylococcus aureus-infected children, highlighting a potential mechanism of immune evasion. This study tested the hypotheses that toxin-specific antibodies protect immune cells from bacterial killing and are associated with improved T cell function following infection.METHODSS.

Antibiotic Treatment of Staphylococcus aureus Infection Inhibits the Development of Protective Immunity.

Recurrent Staphylococcus aureus infections are common, suggesting a failure to elicit protective immunity. Given the emergence of antibiotic resistance, a vaccine is urgently needed, but there is no approved vaccine for S. aureus.

Impaired T-Lymphocyte Responses During Childhood Staphylococcus aureus Infection.

Background: Staphylococcus aureus infections are common throughout the lifespan, with recurrent infections occurring in nearly half of infected children. There is no licensed vaccine, underscoring the need to better understand how S. aureus evades protective immunity.
