What is the difference between viral and bacterial spinal meningitis?
Meningitis is an infection of the tissues covering the brain and spinal cord (meninges). Viral meningitis is an infection caused by viruses and bacterial meningitis is an infection caused by bacteria.
What is the difference in the CSF between a patient that has bacterial meningitis and viral meningitis?
The CSF glucose level is usually within the reference range in viral meningitis, but it may be low in some cases of LCM, HSV, mumps virus, or poliovirus infection. The CSF protein level (reference range, 20-50 mg/dL) is usually elevated in bacterial meningitis.
Does a lumbar puncture show viral meningitis?
To diagnose viral meningitis, the doctor performs a lumbar puncture or ‘spinal tap’ to obtain some of the fluid that normally surrounds the brain and spinal cord. Laboratory tests on this fluid help the doctor decide whether the infection is caused by a virus or other germ such as bacteria.
What are the CSF findings in viral meningitis?
* In most cases of viral meningitis, the CSF WBC is within the range of 10 to 500 cells/microL, though higher values can be seen with some viruses. Normal CSF WBC counts can be seen in enteroviral meningitis, particularly in young infants.
How do I know if I have viral or bacterial meningitis?
Doctors diagnose meningitis by taking different samples of fluid and sending them to a laboratory for analysis. This helps determine whether the person has a bacterial or viral infection. Sometimes, the lab can also identify the type of virus or bacteria.
What does CSF look like in bacterial meningitis?
Bacterial meningitis
See the list below: Appearance: Clear, cloudy, or purulent. Opening pressure: Elevated (>25 cm H2 O) WBC count: >100 cells/µL (>90% PMN); partially treated cases may have as low as 1 WBC/µL.
How do you diagnose viral or bacterial meningitis?
Diagnosing meningitis
Doctors diagnose meningitis by taking different samples of fluid and sending them to a laboratory for analysis. This helps determine whether the person has a bacterial or viral infection. Sometimes, the lab can also identify the type of virus or bacteria.
How can you tell the difference between viral and bacterial?
Bacterial Infections
Symptoms persist longer than the expected 10-14 days a virus tends to last. Fever is higher than one might typically expect from a virus. Fever gets worse a few days into the illness rather than improving.
How do you rule out viral meningitis?
If your doctor suspects viral meningitis, he or she may order a DNA-based test known as a polymerase chain reaction (PCR) amplification or a test to check for antibodies against certain viruses to determine the specific cause and proper treatment.
What is the color of CSF in viral meningitis?
Normal CSF is crystal clear. However, as few as 200 white blood cells (WBCs) per mm3 or 400 red blood cells (RBCs) per mm3 will cause CSF to appear turbid.

Cerebrospinal Fluid Supernatant Colors and Associated Conditions or Causes.
| Color of CSF supernatant | Conditions or causes |
|---|---|
| Purulent CSF | |
| Brown | Meningeal melanomatosis |
Why is bacterial meningitis more serious than viral?
Initial symptoms of viral meningitis are similar to those for bacterial meningitis. However, bacterial meningitis is usually severe and can cause serious complications, such as brain damage, hearing loss, or learning disabilities.
What color is CSF in viral meningitis?
Turbid (cloudy) CSF can reflect infection within the CSF (meningitis). A red color occurs with new blood or brownish with old blood.
When should you suspect bacterial meningitis?
Seek immediate medical care if you or someone in your family has meningitis signs or symptoms, such as: Fever. Severe, unrelenting headache. Confusion.
How do you know the difference between viral and bacterial infection?
As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren’t effective against viruses.
What are 5 differences between viruses and bacteria?
Viruses are not living organisms, bacteria are.
Their “life” therefore requires the hijacking of the biochemical activities of a living cell. Bacteria, on the other hand, are living organisms that consist of single cell that can generate energy, make its own food, move, and reproduce (typically by binary fission).
What are 3 differences between viruses and bacteria?
Viruses are tinier: the largest of them are smaller than the smallest bacteria. All they have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can’t survive without a host. They can only reproduce by attaching themselves to cells.
Is CSF clear or cloudy with bacterial meningitis?
In the presence of bacterial meningitis:
CSF is cloudy (purulent) CSF glucose is decreased in half the cases. WBCs are increased.
What does CSF show in bacterial meningitis?
Typical CSF abnormalities associated with bacterial meningitis include the following: Turbidity. Increased opening pressure (>180 mm water) Pleocytosis (usually of polymorphonuclear (PMN) leukocytes); WBC counts > 10 cells/mm.
What color is CSF in bacterial meningitis?
Why do doctors give antibiotics for viral infections?
Antibiotics do kill specific bacteria. Some viruses cause symptoms that resemble bacterial infections, and some bacteria can cause symptoms that resemble viral infections. Your healthcare provider can determine what type of illness you have and recommend the proper type of treatment.
Can a virus turn into a bacterial infection?
Secondary bacterial infections develop in patients during or after initial infection with an infective pathogen, often a virus (Morris et al., 2017; Wang et al., 2018) and are associated with high morbidity and mortality rates (Figure 1) (Mallia et al., 2012).
How can you tell if it’s viral or bacterial?
Bacterial infections are caused by bacteria, while viral infections are caused by viruses.
Bacterial Infections
- Symptoms persist longer than the expected 10-14 days a virus tends to last.
- Fever is higher than one might typically expect from a virus.
- Fever gets worse a few days into the illness rather than improving.
How can you tell the difference between a viral and bacterial infection?
On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.
