Evidence of transmission of Clostridium difficile in asymptomatic patients following admission screening in a tertiary care hospital.

Background: Clostridium difficile (CD) is the leading cause of infectious health-care associated diarrhea. However, little is known regarding CD carriage and transmission amongst asymptomatic colonizers. We evaluated carriage, characterized strains and examined epidemiologic linkages in asymptomatic colonized CD patients.

Outbreak of extended-spectrum β-lactamase-producing Klebsiella oxytoca infections associated with contaminated handwashing sinks(1).

Klebsiella oxytoca is primarily a health care-associated pathogen acquired from environmental sources. During October 2006-March 2011, a total of 66 patients in a hospital in Toronto, Ontario, Canada, acquired class A extended-spectrum β-lactamase-producing K. oxytoca with 1 of 2 related pulsed-field gel electrophoresis patterns.

Strategies for retaining midcareer nurses.

One method of reducing predicted shortages because of the aging nursing workforce is to increase retention. Few studies have examined the unique needs of midcareer nurses. A mixed-method approach including surveys and focus groups was used to identify key retention strategies and desires for midcareer nurses.

Combination antibiotic susceptibility of biofilm-grown Burkholderia cepacia and Pseudomonas aeruginosa isolated from patients with pulmonary exacerbations of cystic fibrosis.

We identified double and triple antibiotic combinations effective against biofilm-grown Burkholderia cepacia and Pseudomonas aeruginosa sampled from cystic fibrosis (CF) patients undergoing acute pulmonary exacerbations. Sputum bacteria from 110 CF patients were grown as biofilms. Combination antibiotic susceptibility testing was used to test 94 double and triple antibiotic combinations.
