The story is different in HIV and immunocompramized patients where you have to think of listeria, fungi, JC virus, and toxoplasmosis.

Kaplan states S. Pneumo as well for <60 year old adults.

Correct Answer Found it !!!

Ok I did some research on google and it seems like UWorld is right; STREP PNEUNO is the most common cause of ADULT Meningitis. Here are the sources and there excerpts -

1) Meningitis is usually caused by one of a number of bacteria. The most common is Streptococcus pneumoniae. Neisseria meningitidis can cause outbreaks in crowded conditions, such as college dormitories or military barracks.
http://www.emedicinehealth.com/menin...s/page2_em.htm

2) Pneumococcus is the most common cause of adult meningitis.
http://ukhealthcare.uky.edu/content/...?pageid=P00789

3) Streptococcus pneumoniae (pneumococcus). This bacterium is the most common cause of bacterial meningitis in infants, young children and adults in the United States. It more commonly causes pneumonia or ear or sinus infections.
http://www.mayoclinic.com/health/men...SECTION=causes

4) S. pneumoniae is the most common cause of bacterial meningitis in adults, children, and dogs, and is one of the top two isolates found in ear infection, otitis media.
http://en.wikipedia.org/wiki/Streptococcus_pneumoniae

However, WIKI states that "In adults, N. meningitidis and S. pneumoniae together cause 80% of all cases of bacterial meningitis, with increased risk of L. monocytogenes in those over 50 years old. Since the pneumococcal vaccine was introduced, however, rates of pneumococcal meningitis have declined in children and adults."
http://en.wikipedia.org/wiki/Meningitis#Causes

So with all that being said, most sources still show that S. Pneumoniae is the most common organism that causes ADULT Meningitis.
