JC also affects people with lymphoma and leukemia
Meningitis after kideny transplant think of Listeria
I think S. pneumoniae is the most common cause of meningitis in adults ??
Yes it is Pneumococcus
I think S. pneumoniae is the most common cause of meningitis in adults ??
So do I !!!!
Ok guys I checked it again
6-60 N.meningitidis
6 months - 6 years It will be pneumococcus
sorry for that
I would like to figure out something ...
CHILDREN (6 MOS–6 YRS)
S. pneumoniae
Neisseria meningitidis
H. influenzae B
Enteroviruses
There is a logical reason why these bugs are common at this age ( mentioned in Clinical Microbiology Made Ridiculously Simple ,N. meningitidis , P50 ) :
High-risk groups are :
1- Infants aged 6 months to 2 years
2- Aemy recruits
During pregnancy , maternal protective antibodied cross the placenta and provide protection to the neowborn , but only for the first few months of life . Infant will not manufacture their own protective antibodies for a few years . Therefor, there is a window period ( from age 6 months to 2 years ) when infants is extremely susceptible to a meningococcal infection ( meningitis or septicemia ) . Note that Haemophilus influenzae haze a similar antibody-free window .
a second scenario for an invasive meningococcal infection occurs when army recrutis from all over the USA are placed together in close quarters and must survive "boot camp" . In this close-knit group , carrier rates are greater than 40% . Each army recruit my be a carrier of a particular strain of meningococcus that the other army recruits ’s immune systems have never been exposed to , increasing susceptibility to invasive disease . Furthe , due to the mentally and physically exhusting training , the immune system’ability to defend itself is weakened .
thanx guys
