OBJECTIVE
To measure transmission frequencies and risk factors for household acquisition of community-associated and healthcare-associated (HA-) methicillin-resistant Staphylococcus aureus (MRSA).
DESIGN
Prospective cohort study from October 4, 2008, through December 3, 2012.
SETTING
Seven acute care hospitals in or near Toronto, Canada.
PARTICI...

Staphylococcus aureus
(MRSA) bloodstream infections (BSI) are associated with considerable morbidity and mortality, especially with persistent (PB) or recurrent bacteremia (RB).
OBJECTIVE: To determine the frequency of PB and RB in patients with MRSA BSI, and to characterize the isolates from these patients.
METHODS: Surveill...
In 1995, a publicly funded pneumococcal vaccination program for 23-valent polysaccharide vaccine (PPV23) was introduced in Ontario. Conjugate vaccines were authorized in 2001 (PCV7), 2009 (PCV10) and 2010 (PCV13).
From 1995-2011, active, population-based surveillance for invasive pneumococcal disease (IPD) was conducted in Metropolitan Toronto and...
Background: Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is distinct from healthcare-associated MRSA (HA-MRSA) in its epidemiology and microbiologic characteristics. This study describes MRSA transmission and body site colonization patterns within households (HH) of known colonized/infected individuals.
Methods: Inde...
In October 1999, 7 patients with postoperative infections caused by Serratia marcescens were identified at a community hospital in Ontario, Canada. We describe the investigation of this outbreak.
We undertook a case-control study to determine risk factors associated with infection. Case subjects consisted of patients who had undergone surgery and a...
The first case of pneumococcal endometritis with peritonitis in a woman using tampons is described. The patient responded to removal of the tampon and administration of broad spectrum antibiotics. The pathogenesis of pneumococcal endometritis and peritonitis and the potential significance of a tampon in situ are discussed.
