Neisseria Meningitidis is MC in adults than Strep to my knowledge.. this is what i have been sticking with for quite some time now, and have been correctly answer q's. Elderly patients (60+ ull see more Strep). Cheers.

agree with armani i guess that NM is more frequent in young adults ( peak 3-18yo) and strep is more frequent in elederly patients ( peak 50yo and/or immunocompromised...)
hope this helps...G.L/. good article from http://www.emedicine.com/med/topic2613.htm Raymund R Razonable, MD, Consultant, Division of Infectious Diseases, Mayo Clinic of Rochester; Assistant Professor of Medicine, Mayo Clinic College of Medicine ( Last Updated: Aug 28, 2007) Changing Epidemiology of Acute Bacterial Meningitis in the United States* Bacteria 1978-1981 1986 1995 H influenzae 48% 45% 7% Listeria 2% 3% 8% NM 20% 14% 25% S.AGALACT 3% 6% 12% STREP.P 13% 18% 47%

s pn.: it is the most common bacterial cause of meningitis, accounting for 47% of cases. It is also associated with one of the highest mortality rates among the bacterial agents that cause meningitis (19-26%).
18-50 years means adult yes?
