Viral meningitis | An increase in lymphocytes (200-500), normal glucose, and slightly elevated protein levels. |
| |
Bacterial meningitis | An increase in neutrophils (500-20,000), decreased glucose, and elevated protein levels. |
| |
45-100 mg/dL | Normal glucose value. |
| |
14-45 mg/dL | Normal protein level. |
| |
<5 lymphs/mL | Normal lymphocyte count for CSF. |
| |
57% | S. pneumoniae urine test accuracy. |
| |
Haemophilus influenzae | Gram negative coccobacillary rod that is hard to see on a gram stain, but can be found in RBCs. |
| |
Haemophilus influenzae | Smells like a Micro lab hallway. |
| |
positive, positive | Haemophilus influenzae is catalase:____________ and oxidase:____________. |
| |
X Factor | Heat stable tetrapyrrole compounds that are found often in iron-containing pigments. |
| |
V Factor | NAD or NADP |
| |
Heat | What allows Haemophilus to grow on sheep's blood agar? |
| |
Porphyrin test | This test looks for X factor independent Haemophilus. |
| |
Fluorescence | A positive result in the porphyrin test is... |
| |
Porphobilinogen or porphyrin | What is produced by an X factor independent organism in the Porphyrin test? |
| |
Neisseria meningitidis | Gram negative diplococci that look like kidney beans. |
| |
BAP, CHOC, and Thayer Martin | Agars that Neisseria grows well on. |
| |
positive, positive | Neisseria meningitidis is catalase:____________ and oxidase:____________. |
| |
Beta-lactamase | Always do this test if Neisseria meningitidis is discovered. |
| |
Optochin sensitivity | This test requires CO₂ incubation and shows sensitivity at >14mm of zone. |
| |
Bile solubility | This test looks for the presence of autocatalytic enzymes in S. pneumoniae. |
| |
alpha-hemolysis | Streptococcus pneumoniae shows this kind of hemolysis. |
| |
Viridans strep | Other alpha streps are called this... |
| |
GBS | Gram positive cocci that are in pairs and short chains and have large colonies and small zones of beta-hemolysis. |
| |
GBS | This organism is responsible for childbed fever and related fatalities in women and babies. |
| |
CAMP, Hippurate, Bacitracin, PYR | The four identifying tests for GBS. |
| |
Listeria | Gram positive rod that is a facultative anaerobe that is non-sporeforming. |
| |
Listeria | Grows well on BAP and looks like GBS with small zone of hemolysis excepting that the catalase result is positive as opposed to the GBS. |
| |
Listeria | Likes cold temperatures and refrigeration, and is found often in dairy products during outbreaks |
