background aseptic meningitis is the most common type of meningitis and is characterized by meningeal inflammation that is not linked to identifiable bacterial pathogens in cerebrospinal fluid (csf). objectives this study aimed to evaluate the frequency of aseptic meningitis caused by herpesviruses, namely herpes simplex types i and ii (hsv-1, hsv-2), epstein-barr virus (ebv), cytomegalovirus (...

Gram-negative cocci found in samples of purulent spinal fluid during routine laboratory examinations are apt to be reported as meningococci without further confirmation. While the meningococcus no doubt is the most common gram-negative coccus associated with acute meningitis, there are many others which play a r6le, particularly in sporadic cases. Error in diagnosis is also apt to occur in cert...

Among hospital-associated infections, healthcare-associated central nervous system infections are quite important because of high morbidity and mortality rates. The causative agents of healthcare-associated meningitis differ according to the status of immune systems and underlying diseases. The most frequent agents are Gram-negative bacilli (Pseudomonas spp., Acinetobacter spp., Escherichia col...

The simultaneous detection of Neisseria meningitidis, Haemophilus influenzae, and Streptococcus sp. was assessed by polymerase chain reaction (PCR) for the diagnosis of bacterial meningitis, as well as the applicability of PCR as a routine test. A cohort study was carried out with 182 children (2 months to 12 years of age) with suspicion of bacterial meningitis. Routine tests identified the eti...

objective: bacterial meningitis is a dangerous and sometimes fatal infection that affects the central nervous system. because some antibiotics can prevent some types of these bacteria and supress them from spreading and infecting, therefore it is important to know what type of virus or bacterium is causing meningitis. haemophilus influenzae and neisseria meningitides are the two main pathogens...

INTRODUCTION Clinically, increased cerebrospinal fluid (CSF) adenosine deaminase (ADA) level is an important diagnostic clue of tuberculous meningitis. However, increased CSF ADA level can be caused by other neurological diseases. CASE DESCRIPTION We report a case of a 67-year-old woman with cryptococcal meningitis presented with increased ADA level of the CSF. In parallel with her recovery, ...

OBJECTIVE To assess the performance of cerebrospinal fluid (CSF) lactate as a biomarker to differentiate bacterial meningitis from viral meningitis in children, and to define an optimal CSF lactate concentration that can be called significant for the differentiation. METHODS Children with clinical findings compatible with meningitis were studied. CSF lactate and other conventional CSF paramet...
