Outbreaks of methicillin-resistant Staphylococcus aureus among staff and dogs in Swedish small animal hospitals.

Methicillin-resistant Staphylococcus aureus (MRSA) was found in a dog for the first time in Sweden in 2006. Between October 2006 and May 2007, MRSA was diagnosed in 7 more dogs that had been treated in 3 different small animal hospitals, located 150-200 km apart, in different counties of Sweden. Screening of the animal hospital staff and environment in these small animal hospitals showed 20 of 152 staff to be positive for MRSA, with rates between 2% and 18% in the different hospitals, while all 128 environmental samples were negative.

Alarming spread of vancomycin resistant enterococci in Sweden since 2007.

The total number of persons infected or colonised with vancomycin-resistant enterococci mandatorily reported to the Swedish Institute for Infectious Disease Control increased dramatically during 2007 and 2008. During a period of twenty months from 1 July 2007 to 28 February 2009, a total of 760 cases were reported compared with 194 cases reported during the entire period from 2000 to 2006. This rise was mainly attributed to a wide dissemination of vancomycin resistant enterococci which started in a number of hospitals in Stockholm in the autumn of 2007 and was followed by dissemination in various healthcare facilities (hospitals and homes for the elderly) in a further two Swedish counties in 2008.

Once- versus twice-daily amikacin regimen: efficacy and safety in systemic gram-negative infections. Scandinavian Amikacin Once Daily Study Group.

Three hundred and sixteen patients with serious infections verified or suspected to be of Gram-negative aetiology were treated in an open, randomized, comparative multicentre study with amikacin 15 mg/kg/day given either as a single dose or in two divided doses at 12 h intervals. Two hundred patients were evaluated for efficacy and all 316 for safety. The efficacy of both dosage regimens was very good with a satisfactory clinical response in 90% of the patients.
