BACKGROUND An outbreak of Escherichia coli O157:H7 was identified in Oregon through an increase in Shiga toxin-producing E. coli cases with an indistinguishable, novel pulsed-field gel electrophoresis (PFGE) subtyping pattern. METHODS We defined confirmed cases as persons from whom E. coli O157:H7 with the outbreak PFGE pattern was cultured during(More)
Congenital tuberculosis (CTB) due to maternal genitourinary (GU) TB infection is a rare occurrence, as infection of the genital tract in women generally leads to infertility. Increasing availability of assisted reproductive technology creates the potential for CTB to emerge as a significant problem. We describe five infants (two sets of twins and a(More)
Cryptosporidium, a parasite known to cause large drinking and recreational water outbreaks, is tolerant of chlorine concentrations used for drinking water treatment. Human laboratory-based surveillance for enteric pathogens detected a cryptosporidiosis outbreak in Baker City, Oregon during July 2013 associated with municipal drinking water. Objectives of(More)
CONTEXT AND OBJECTIVES Synthetic cannabinoids are illegal drugs of abuse known to cause adverse neurologic and sympathomimetic effects. They are an emerging health risk: 11% of high school seniors reported smoking them during the previous 12 months. We describe the epidemiology of a toxicologic syndrome of acute kidney injury associated with synthetic(More)
OBJECTIVE To establish a statewide network to detect, control, and prevent the spread of carbapenem-resistant Enterobacteriaceae (CRE) in a region with a low incidence of CRE infection. DESIGN Implementation of the Drug Resistant Organism Prevention and Coordinated Regional Epidemiology (DROP-CRE) Network. SETTING AND PARTICIPANTS Oregon infection(More)
Carbapenem-resistant Enterobacteriaceae (CRE) are an urgent public health threat. We evaluated the capacity of the Carba NP test to detect carbapenemase production in 206 isolates: 143 Enterobacteriaceae identified by Oregon's CRE surveillance program in 2013 and 63 known carbapenemase-positive organisms. Overall, test sensitivity and specificity were 89%(More)
BACKGROUND Health care worker (HCW) hand hygiene (HH) is the core strategy to prevent health care-associated infections (HAI). Suboptimal HCW HH rates continue despite hospital efforts to increase compliance. OBJECTIVES To determine whether parents of hospitalized children perceive they have a role in preventing HAI and whether they are willing to remind(More)
OBJECTIVE To determine the scope, source, and mode of transmission of a multifacility outbreak of extensively drug-resistant (XDR) Acinetobacter baumannii. DESIGN Outbreak investigation. SETTING AND PARTICIPANTS Residents and patients in skilled nursing facilities, long-term acute-care hospital, and acute-care hospitals. METHODS A case was defined as the(More)
The first Oregon case of New Delhi metallo-β-lactamase-1 (NDM-1)-producing Escherichia coli was reported during November 2013. Epidemiologic investigation revealed only local outpatient medical care and no travel outside Oregon for both the patient and his household contact. Environmental sampling discovered a matching isolate from the patient's household(More)
