ESBL stands for Extended-Spectrum beta-Lactamase. Beta lactamases are enzymes that are produced by many types of bacteria (germs) which make them more resistant to antibiotics and can make the infection harder to treat.
Beta interferons are recommended for the treatment of 'active' relapsing MS. This has been defined in guidelines as when you have two or more relapses in the last two years. But more and more MS specialists are defining 'active' MS as one recent relapse and/or signs on MRI scans that MS is active. You can take beta interferons: If you have relapsing MS and you've had a recent relapse and/or if MRI scans show new signs that your MS is active (you have new lesions).
