Outbreak of Multiresistant OXA-24- and OXA-51-Producing Acinetobacter baumannii in an Internal Medicine Ward.

Outbreak of Multiresistant OXA-24- and OXA-51-Producing Acinetobacter baumannii in an Internal Medicine Ward. Jpn J Infect Dis. 2013;66(4):323-6 Authors: Tena D, Martínez NM, Oteo J, Sáez D, Vindel A, Azañedo ML, Sánchez L, Espinosa A, Cobos J, Sánchez R, Otero I, Bisquert J Abstract Here we describe the clinical, microbiological, epidemiological, and molecular characterization of an outbreak of multidrug-resistant Acinetobacter baumannii (MRAB) involving 5 patients admitted to the internal medicine ward of our hospital. Over a 6-week period, 5 MRAB isolates were recovered from 5 patients, including 1 with fatal meningitis, 3 with skin and soft tissue infections, and 1 with respiratory colonization. One sample obtained during environmental monitoring in the ward was A. baumannii-positive. According to the pulsed-field gel electrophoresis typing results, the strains isolated from all patients and the environmental sample belonged to a single clone, identified as ST79 by multilocus sequence typing. The blaOXA-24 and blaOXA-51 carbapenemases were detected in all isolates. Four patients died, but only the death of the meningitis patient was probably related to the A. baumannii infection. The infection source was probably the hands of the healthcare workers because the outbreak strain was isolated from the surface of a serum container. The results of the present study revealed the importance of strict adherence to control measure...

ConclusionsThis study provides initial perspectives on measles preparedness among Idaho CAHs, despite limited generalizability. Future studies should explore whether self-reported preparedness measures reflect the ability of the CAHs to control measles spread when cases present for care.

Authors: De Wolfe TJ, Safdar N, Meller M, Marx J, Pfau PR, Nelsen EM, Benson ME, Soni A, Reichelderfer M, Duster M, Gopal DV Abstract Duodenoscope use in healthcare facilities has been associated with transmission of multidrug resistant pathogens between patients. To assist healthcare facilities in monitoring the quality of their duodenoscope reprocessing procedures and limit patient risk of infection, the Centers for Disease Control and Prevention (CDC) deployed voluntary interim duodenoscope sampling and culturing surveillance protocols in 2015. Though the interim methods were widely adopted, alternative surveill...

DufourAbstractIn the French bovine tuberculosis (bTB) surveillance program, tracing-on and back investigations have a major importance as, in 2016, they represented about 21% of the detected outbreaks. Building on our previous work on the other surveillance system components (Poirier et al., 2019), we evaluated for the first time the sensitivity and the cost of the two existing protocols of bTB’s tracing-on investigations trough scenario tree modelling with a stochastic a...
