Is epilepsy viral or bacterial?
Infections are important cause epilepsy in developing countries, the frequency of which may differ widely in different locations. Viral, bacterial, fungal and parasitic infections can result in epilepsy.
What are the 7 pathogens?

- Bacteria. Bacteria (bak-TEER-ee-uh) are tiny, single-celled organisms that get nutrients from their environments.
- Viruses. Viruses are even smaller than bacteria.
- Fungi. Fungi (FUN-guy) are multicelled, plant-like organisms.
- Protozoa.
What magnification is required to see bacteria?
While some eucaryotes, such as protozoa, algae and yeast, can be seen at magnifications of 200X-400X, most bacteria can only be seen with 1000X magnification. This requires a 100X oil immersion objective and 10X eyepieces.. Even with a microscope, bacteria cannot be seen easily unless they are stained.
What can I see at 1000x magnification?
At 1000x magnification you will be able to see 0.180mm, or 180 microns.
Why do you start on the lowest magnification?
When using a light microscope it’s important to start with the low power objective lens as the field of view will be wider, increasing the number of cells you are able to see. This makes it easier to find what you’re looking for.
What magnification do you need to see Tardigrades?
20-50X
Are Tardigrades in tap water?
Don’t use tap water, which may contain chlorine that can kill tardigrades.
How do you kill a Tardigrade?
It took heating to 82.7 °C (180.9 °F) to kill half of tun-state tardigrades within 1 hour. Longer exposure time decreased the temperature needed for lethality, though. For 24 hours of exposure, 63.1 °C (145.6 °F) was enough to kill half of the tun-state tardigrades.
How do I identify a Tardigrade?
Most tardigrade species will be easiest to spot with a light source from above against a dark background. The bottom of the petri dish can be painted with black enamel paint. Systematically search through the dish with a stereomicroscope using 20-30x magnification.
