Pantoea septica bacteremia in a 3-month-old infant with RAG2 severe combined immune deficiency: A case report.

We present the case of a 3-month-old immunocompromised infant who developed a vascular catheter-related bloodstream infection caused by Pantoea septica. Susceptibility testing results for this isolate and 10 additional clinical strains are provided to help define the susceptibility profile of this infrequently recovered organism.

Syphilis in pregnancy and infant outcomes in Manitoba.

Background: Infectious syphilis has been increasing in incidence in Manitoba since 2012, especially in heterosexual women of childbearing age resulting in an increasing number of infants with in utero exposure and who are at risk for congenital syphilis (CS). We aimed to evaluate the impact of syphilis in pregnancy on infants and to describe our experience with CS.

Methodology: This retrospective 2012 to 2018 cohort study reviewed women with syphilis in pregnancy and short-term infant outcomes.

Infectivity of severe acute respiratory syndrome coronavirus 2 in children compared with adults.

Background: The role of children in the transmission and community spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unclear. We aimed to quantify the infectivity of SARS-CoV-2 in nasopharyngeal samples from children compared with adults.

Methods: We obtained nasopharyngeal swabs from adult and pediatric cases of coronavirus disease 2019 (COVID-19) and from their contacts who tested positive for SARS-CoV-2 in Manitoba between March and December 2020.

Successful Treatment of High-Level Aminoglycoside-Resistant Bacteremia in a Preterm Infant with Ampicillin and Cefotaxime.

Enterococcal bloodstream infections are usually treated with single-agent antibiotics. In persistent infections, synergistic combination therapy is often required with a beta-lactam and an aminoglycoside antibiotic. High-level aminoglycoside-resistant (HLAR) enterococci are increasingly prevalent and preclude the use of this combination.
