Got a sore throat? Wonder if your painful sore throat is from a cold, strep throat, ortonsillitis? Here's how to tell.
What's the difference between a cold, strep throat, and tonsillitis?A sore throat is often the first sign of a cold. However, a sore throat from a cold often gets better or goes away after the first day or two. Other cold symptomssuch as a runny nose and congestion may follow the sore throat.
Strep throat, which is caused by Streptococcus bacteria, is one of the major causes of sore throat and tonsillitis. With strep throat, the sore throat is often more severe and persists. While a cold goes away on its own, strep throat usually requires antibiotics.
Tonsillitis is a painful infection of the tonsils, the tissue masses located at the back of the throat.
Is a sore throat with a cold caused by a virus or bacteria?Sore throats can be caused by viruses or bacteria. To determine the cause of your sore throat, your doctor may do a strep test. However, there may be some clues. Viral sore throats are often accompanied by other cold symptoms that may include a runny nose, cough, red or watery eyes, and sneezing.
Along with a sore throat, what are other cold symptoms?Other cold symptoms include the following:
- Runny nose
- Sneezing
- Cough
- Headache
- Nasal congestion
- Fever, which may or may not be present and which is more likely in children
While there is no cure for a sore throat caused by a cold virus, to speed healing of your sore throat and cold, be sure to get enough rest. Eating a healthy diet and drinking plenty of fluids can also help speed healing.
Can medications relieve symptoms of a sore throat with a cold?Over-the-counter cold medications may relieve cold and sore throat symptoms. However, the benefits of these medications are minimal. Some cold medications include the following:
- Pain relievers, such as acetaminophen and ibuprofen, to relieve the aches and pains of a cold and sore throat. (Aspirin should not be given to children under the age of 18 because of its link to Reye's syndrome, a disorder that mostly affects children 4 to 12 years old and causes brain damage and death.)
- Sore throat sprays and lozenges to soothe your throat and numb the throat pain temporarily.
- Decongestant nasal sprays to relieve a sore throat caused by postnasal drip -- nasal drainage that runs down your throat. (Be sure to stop using nasal decongestant sprays after 3 days, or you may have an increase in congestion when you stop them.)
Antibiotics should not be used to treat a cold virus and sore throat. Antibiotics are effective only against bacteria. They will not work on sore throats associated with colds, which are caused by viruses, and may cause future infections to be worse and last longer.

What is the indicator that turns the agar medium pink with copper?
MacConkey agar contains bile salts, lactose, peptone. crystal violet dye, and neutral red dye. The agar appears a medium pink with a copper undertone.
Why aerobacter aerogens produces pink colour in EMB agar?
Aerobacter aerogenes produces a pink color on EMB agar due to its ability to ferment lactose, which results in the production of acid byproducts. This acidic environment causes the neutral red pH indicator in the agar to turn pink. This characteristic color change helps differentiate Aerobacter aerogenes from other bacterial species on the agar plate.
What is the color of mac conkey agar of klebsiella?
It's pink, since it can use lactose as it's nutrition source
What is the culture characteristic of Ecoli thst grow on macconkey agar?
E. coli that grow on MacConkey agar typically exhibit lactose fermentation, causing them to produce pink or red colonies. These colonies may also appear mucoid due to the production of a polysaccharide capsule. Additionally, E. coli on MacConkey agar will typically not grow well under acidic conditions, as the agar contains crystal violet which inhibits the growth of Gram-positive bacteria.
What color is S marcescens in an agar slant tube?
Serratia marcescens makes a bright red streak on an agar slant
What is color of YEM agar medium?

Can macConkey Agar plates test for e coil?
Yes, MacConkey Agar plates can help in detecting E. coli. On MacConkey Agar, E. coli typically produces pink colonies due to its ability to ferment lactose, leading to acid production that changes the pH indicator in the agar. E. coli colonies that are pink indicate lactose fermentation, while non-fermenting bacteria will appear colorless.
What will grow pink or red colonies on nutrient agar?
Bacteria such as Serratia marcescens are known to produce pink or red pigmented colonies on nutrient agar. These colonies can range from a bright pink to deep red color and are often used as indicators in microbiology labs.
What is the color of mac conkey agar of klebsiella?
It's pink, since it can use lactose as it's nutrition source

What microorganism forms a pink colony on MacConkey agar?
Well, Macconkey Agar II plates have Gram Crystal Violet in them so there are a number of bacterial species that can absorb it and turn "very pink." The way to narrow it down is to identify whether it grows in chains or clusters. But other than that, it is hard to tell.
How does yersinia look on nutrient agar EMB agar and MacConkey agar?
On nutrient agar, Yersinia appears as smooth, opaque colonies with a pale yellowish color. On EMB agar, colonies may show greenish metallic sheen due to lactose fermentation. On MacConkey agar, Yersinia typically forms colorless to pale pink colonies due to its inability to ferment lactose.
Why colony of agrobacterium is pink on yeast extract agar media?
The pink color of Agrobacterium colonies on yeast extract agar media is due to the production of a pigment called violacein. The presence of violacein is a characteristic feature of Agrobacterium species and contributes to the pink color of the colonies. This pigment production can help to differentiate Agrobacterium from other bacteria on culture plates.
What is the colony morphology of klebsiella pneumonia on macconkeys and nutrient agar?
On MacConkey's agar, Klebsiella pneumoniae appears as pink or mauve mucoid colonies with a metallic sheen. On nutrient agar, it appears as smooth, round, and convex colonies with a pale white or cream color.
