ABSTRACT

We report a case of a 62-year old man treated for a Streptococcus pneumoniae meningitis by ceftriaxone and dexamethasone. After a neurological improvement, neurological degradation by vasculitis occurred, despite effective concentrations of ceftriaxone in serum and CSF. S. pneumoniae with increased MICs to third-generation-cephalosporins (3GC) was isolated from the ventricular fluid ten days after the isolation of the first strain. Isolates analysis showed that a mutation of penicillin-binding proteins in PBP2x has occurred under treatment.

I am an Italian blogger, active since 2005 with main focus on emerging infectious diseases such as avian influenza, SARS, antibiotics resistance, and many other global Health issues. Other fields of interest are: climate change, global warming, geological and biological sciences. My activity consists mainly in collection and analysis of news, public services updates, confronting sources and making decision about what are the 'signals' of an impending crisis (an outbreak, for example). When a signal is detected, I follow traces during the entire course of an event. I started in 2005 my blog ''A TIME'S MEMORY'', now with more than 40,000 posts and 3 millions of web interactions. Subsequently I added an Italian Language blog, then discontinued because of very low traffic and interest. I contributed for seven years to a public forum (FluTrackers.com) in the midst of the Ebola epidemic in West Africa in 2014, I left the site to continue alone my data tracking job.
