A patient has presented with symptoms consistent with bacterial meningitis. A rapid latex agglutination test has been used to detect bacterial antigen in cerebrospinal fluid (CSF). The test can detect antigen from: Streptococcus group B Haemophilus influenzae type b Streptococcus pneumoniae (pneumococcus) Neisseria meningitidis (meningococcus) groups A, B, C, Y or W135 Escherichia coli K1 All of these aforementioned bacterial pathogens can cause the disease meningitis. Note: the E. coli K1 antigen and the Neisseria meningitidis (meningococcus) group B antigen are structurally and immunologically related and cannot be distinguished by this test.

Question

A patient has presented with symptoms consistent with bacterial meningitis. A rapid latex agglutination test has been used to detect bacterial antigen in cerebrospinal fluid (CSF). The test can detect antigen from:  Streptococcus group B Haemophilus influenzae  type b Streptococcus pneumoniae  (pneumococcus) Neisseria meningitidis  (meningococcus) groups A, B, C, Y or W135 Escherichia coli  K1 All of these aforementioned bacterial pathogens can cause the disease meningitis.    Note: the  E. coli  K1 antigen and the  Neisseria meningitidis  (meningococcus) group B antigen are structurally and immunologically related  and  cannot  be distinguished by this test.  
 View and interpret the test results shown below. A positive control has also been included.

Select the most accurate interpretation of the test result:

Answer

The test result indicates the presence of the  Neisseria meningitidis  (meningococcus) groups A, C, Y  or W135  antigen  OR   N. meningitidis  group B in the test sample

Answer

The test result indicates the presence of the  Haemophilus influenzae  type b antigen in the test sample

Answer

The test result indicates the presence of the  Streptococcus  group B (Strep B) antigen in the test sample

Answer

The test result indicates the presence of the  Streptococcus pneumoniae  antigen in the test sample

Answer

The patient is negative for bacterial meningitis and may instead be presenting with symptoms consistent with viral meningitis

Answer

The test result indicates the presence of the  Neisseria meningitidis  (meningococcus) groups A, C, Y  or W135  antigen in the test sample.  N. meningitidis  group B is not present.
