Gram-Positive Rods on a Cerebrospinal Fluid Gram Stain

Cerebrospinal fluid (CSF) access device placement in the pediatric population presents challenges due to the development of infections following placement, access or revision, and/or shunt malfunctions. Here we report an unusual pediatric case of L. monocytogenes ventriculitis/VP shunt (VPS) infection and associated pseudocyst with an emphasis on the importance of VPS removal in clearing the in...

Comparison of bacterial antigen test and gram stain for detecting classic meningitis bacteria in cerebrospinal fluid.

The bacterial antigen test (BAT) screens cerebrospinal fluid (CSF) or other body fluids for antigens of classic bacterial meningitis pathogens (i.e., Streptococcus pneumoniae, Haemophilus influenzae type b [Hib], group B Streptococcus species, Neisseria meningitidis, and Escherichia coli K1) (7). The utility of the BAT has been questioned in several published reports (2, 5, 6, 8, 12, 15). Furth...

Post-neurosurgical meningitis; gram negative bacilli vs. gram positive cocci

Background: Post-neurosurgical meningitis is a significant cause of mortality and morbidity. In this study we aimed to compare the differences of clinical, laboratory features and outcomes between the post-neurosurgical meningitis caused by gram-negative bacilli (GNB) and gram-positive cocci (GPC). Methods: Cases of post-neurosurgical meningitis (with positive CSF culture) were included. After...
