Characteristics of hospital- and community-acquired meticillin-resistant Staphylococcus aureus in Tehran, Iran.

abstract：:Francisella tularensis has been recognized as the causative agent of tularaemia for almost a century. Since its discovery in 1911, it has been shown to infect a wide range of hosts, including humans. As early as the 1920s it was suggested to be an intracellular pathogen, but it has proven to be an enigmatic organism, ...

abstract：:The possession of any of eight different plasmids by Staphylococcus aureus strain 649--either singly or simultaneously (in no. 649MR)--caused changes in growth kinetics. Six of the plasmids caused an increase in exponential doubling time (by 8-25%), and most also altered the duration of the lag period. Strain 649MR wa...
