We can not swab bacteria directly on to a petridish its because swab's front part contain cotton which may damage the evenness of the agar in petridish so its better to draw the bacteria from swab to a broth after 24 hours if it is innoculated on to petridish with sterile loop we can grow the bacteria

What the most common way to grow bacteria is?
The most common way to grow bacteria is in an agar petri dish. The bacteria are usually placed by a swab into the petri dish and incubated for a predetermined period of time (The agar serves as a food source for the bacteria). Then, growth, or no growth, of bacteria will be observed.
How do you test if wiping a doorknob with antibacteria wipes reduce the number of bacteria?
You will test it by before wiping the doorknob with the antibacterial wipe, use a cotton swab and wipe it around the door knob.... use agar and wipe the swab into a petri-dish with the agar. After wiping the doorknob using the antibacterial wipe, use another cotton swab to wipe the doorknob then wipe it into another petri-dishagar= helps grow
What has much bacteria?
Things that have a high concentration of bacteria include:the human moutha human bite, even more than a dog bitethe intestines especially E-Colia dirty stagnant pondstagnant swampy waterGalapagos Monitor salivaa swab from a highly infected wounda petri dish in the lab
Why is a sterile applicator swab used to obtain the specimen?
If you use one that isn't sterile, you will not know where the bacteria are from. The swab or the area you swabbed.
Why is a sterile swab used to collect bacteria in the mouth?
because it is important that in nutrient media to grow up only bacteria that may be present in your mouth.In tha case tha swabs are not sterile in nutrient media will growth mouth and swab bacteria and the will give a flas positive result.
How do you grow bacteria using a petri dish?
To grow bacteria on a petri dish, you will need several items.First you will need a petri dish with lid. The petri dish must contain agar, which is the source of the nutrients for the bacteria you want to grow.Then you will need sterile cotton tipped applicators. They must be sterile so that the bacteria you put in your dish is the only bacteria there, and not extra from an exposed cotton swab. There are also other laboratory tools that can be sterilized to pick up bacteria with.Then you need your source of bacteria.When you know what type of surface you will be swabbing, isolate one area, and swab it thoroughly with the cotton tipped applicator. Then, immediately swab it gently onto the agar surface with a back and forth motion.If testing two different specimens with one petri dish, be sure to only swab half of each side with each specimen. On the bottom of the dish, use a marker to note which side contains which sample.After preparing your petri dishes, place the lid on them and be sure they are labeled for easy identification. Then your specimens need to be incubated. Different types of bacteria thrive better at different levels of incubation and time. See a laboratory manual for incubation times.

What is incubation used for in culturing?
When doctors are trying to determine what bacteria is causing an illness they sometime get a sample from the person and swab it on a shallow glass dish that contains a material the bacteria like and grow on. Once the bacteria has grown into colonies technicians look at them under a microscope to determine what the bacteria is. The process of growing the colonies of bacteria is called culturing

Explain about wound culture and procees of Wound culture?
dgfxfdhmtyhjnrujytrju dgfxfdhmtyhjnrujytrju Hmm, I'm not sure those 2 are really answers... The "wound culture" is a fairly common laboratory test ordered when a physician, PA, or NP wants to know: 1.) exactly what microorganism is causing a wound infection and 2.) exactly what anti-microbial drug to to treat the infection. Most commonly, a nurse or doctor will use a sterile swab to collect material from the wound. The swab is sent to the laboratory to be "plated." This simply means a medical technologist will drag the swab over a variety of "growth media" (petri dishes with firm, jelly like material and nutrients in them) and then incubate the petri dishes at controlled temperatures and gas concentrations. It takes a highly trained person to look at one of these petri dishes after it has been incubated to tell if there are any pathogens growing (pathogens are microorganisms that can cause disease or infection.) Once the medical technologist finds suspicious colonies growing (colonies are millions of bacteria piled up on the petri dish that look like small dots - and can be many different colors) they do a gram stain test, biochemical testing, and an antibiotic test to determine what the organism is and how best to treat it. You can think of it like microbiology detective work. Many times bacteria are found, but fungi can also be found! In most cases, the bacteria and antibiotic susceptibility profile will be complete in 2-3 days. Fungi and "acid-fast" bacteria like the Tuberculosis bacilli, can take much longer 7 days to months!
What is a culture of the sinus?
A culture is when they take a swab of a part of your body and then touch that swab on a medium, which is usually a sort of jelly with nutrients in it. Bacteria from the swab grow on this medium and can usually be identified so the doctor knows what exactly to treat and what drugs would be effective against the strain isolated.
How come a dog's mouth is cleaner than a human's?
To complete this test you will need access to certain supplies. However, take a swab of the inside of a dogs mouth and place it in a petri dish on top of a nutritional solution and do the same thing to yourself. Cover the petri dishes with their counterparts. Then incubate the petri dishes in a warm environment and wait 24 to 48 hours. Then remove the petri dishes and see how many more germ spots have grown on top of the nutritional solution.
When you put food color dye with milk ON A DISH then you take some dish soap with a cottonswab why does THE DYE spread awaY from the swab?
OMG i tried that but im not sure sorry tell me if u find out im curioys
To do Dog saliva science fair project should you get dog spit in al ittle container or swab the gums and rub it on the bacteria?
For a science fair experiment you can experiment if a dog's saliva kills bacteria. First you get bacteria and put it on four microscpe slides. Then, you swab two dogs' mouths for saliva and then you put the saliva of one of the dogs on two of the slides and do the same with the other dog's saliva. Let it set for 24 hours and see if there is less bacteria than before.
