One of the newest techniques used to identify bacteria is to determine their?

genetic signature, specifically by analyzing the unique pattern of genes present in the bacteria's genome. This method, known as whole-genome sequencing, allows for highly accurate identification of bacterial species and strains. It is a powerful tool in microbial ecology, epidemiology, and clinical diagnosis.

What bacteria is a sphere shape bacteria?

Cocci bacteria are spherical in shape. They can exist singly, in pairs (diplococci), in chains (streptococci), or in clusters (staphylococci). Some common examples include Staphylococcus aureus and Streptococcus pneumoniae.

What is the procedure of cryopreservation of bacterial culture?

The procedure of cryopreserving a bacterial culture involves mixing the culture with a cryoprotectant, such as glycerol, to prevent damage from freezing. The mixture is then aliquoted into cryovials and placed in a -80°C freezer or liquid nitrogen for long-term storage. Thawing of the culture involves quickly immersing the vial in a water bath at 37°C and transferring the culture to fresh growth media.

When bacteria in your body how does it defends itself?

the bacteria attaches itself to healthy cell and slowly destroys them when they multiply. this is also true for viruses. when you feel bad or sore throat, that is simply the bacteria/virus being fought off.

Is asbestos a bacteria?

Asbestos is not bacteria. It is a fibrous mineral that has been used for ages in everything from construction to clothing. It was once considered a great building material because of its heat resistant properties among other things.

Asbestos affects the human body when the fibers are inhaled, generally causing cancer.

Does green works by Clorox kill kitchen bacteria?

Sorry, I had to modify the earlier answer. NO, Clorox Green Works is not a disinfectant. From About.com Housekeeping one of the "Cons" of Green Works is that it does not (yet) provide any "antibacterial" properties. In fact, the Clorox site even states that the product is not a disinfectant. So yea....it's kind of awkward.....why use it then? If it doesn't kill germs? There is even a review on that same page, from a user who did "laboratory tests" (take that with a grain of salt) - that showed that it didn't "clean" much. And likely, most of the "cleaning" was due to the friction (read: elbow grease) against the kitchen surfaces.

There are other techniques for counting bacteria such as a direct microscopic count and turbidity Why is the standard plate count preferrend for food?

The standard plate count method is preferred for counting bacteria in food because it provides a simple and reliable way to determine the number of viable bacteria present. It allows for the cultivation of various types of bacteria which may be present in the sample, providing a more accurate representation of the bacterial population. Additionally, the standard plate count method is well-established, widely accepted, and can be easily standardized for regulatory purposes in the food industry.

What is A species of bacteria that lives in the intestines of many mammals?

Escherichia coli (E. coli) is a common species of bacteria that resides in the intestines of mammals, including humans. It plays a vital role in digestion and nutrient absorption.

Which extreme conditions do halophiles thrive?

Halophiles are able to live in salty environments by adopting themselves in unique manner. Generally,a live cell will tend to lose its content when placed in a hypertonic solution and will tend to accumulate liquid inside the cell when placed in hypertonic solution. But,the halophiles combat this situation by accumulating high concentration of kcl inside the cell,so as to provide an isotonicenvironment

What are ways bacteria affect other organisms?

Bacteria live all over and throughout the human body. Bacteria living in our intestines are critical for our digestion, and we need them to live healthily. Others can cause many diseases if they get into or onto our bodies and begin growing.

What rhymes with bacteria?

Some words that rhyme with bacteria are cafeteria and hysteria.

How does bacteria get there food?

Bacteria obtain their food by breaking down organic matter such as sugars, proteins, and fats through a process called enzymatic digestion. Some bacteria are able to produce their own food through processes like photosynthesis, while others rely on consuming dead organic material or other organisms for nutrients.

Endogenous infectious agents arise from microbes that are?

naturally present or originate within the host's body, such as bacteria or viruses. These agents can cause diseases when they disrupt the body's normal functioning and immune response.

What organisms may be mistaken for Neisseria gonorrhea?

Other gram-negative diplococci, like Moraxella and Kingella species, may be mistaken for Neisseria gonorrhoeae due to their similar appearance under the microscope. Additionally, some non-pathogenic Neisseria species, such as Neisseria meningitidis or Neisseria lactamica, could be confused for Neisseria gonorrhoeae in laboratory samples. Confirmation through specific biochemical tests or molecular methods is necessary to accurately identify Neisseria gonorrhoeae.

Is carbol fuchsin the same as safranin?

No. safranin is the classic stain used in gram staining. Concentrated Carbol Fushin is mainly used for the ZN staining procedure to stain organisms such as Vibrio cholerae and Cryptosporidium. Diluted Carbol Fushin can however be used as a replacement counterstain for Safranin in the gram stain.

Is streptococcus curable?

Can I just say why post theese crappy messages the answer boards as people might want to take an interest in human anotomy. Yes meningitis is curable if it is viral meningtis you can have a dose of antibiotics to clear it up and with bed rest it would have been cured within a week or with bacterial meningitis which is a lot more advanced hospital care with penicillin and various different types of drugs to try to cure the disease.

Can bacteria be seen with a compound microscope?

Yes and no. There is a trick you can use to visually detect the presense of bacteria but all you will see is points of light, not the actual shape of the bacteria themselves. The trick is: * have the bacteria suspended in some transparent medium (water or air) * have a black back-drop * shine a bright source of light through the medium at right angles to your perspective * you will see bright points of light against the black back drop but not be able to resolve details.

Can bacteria infection be in the rectum?

Yes, bacterial infections can occur in the rectum. Common examples include bacterial proctitis, which is inflammation of the rectal lining caused by bacterial infection, and sexually transmitted infections like chlamydia and gonorrhea that can affect the rectum. These infections can cause symptoms such as rectal pain, discharge, and bleeding.

Do you have bacteria when you are sick?

No.

A fetus develops inside the amniotic sac.

Its genetic material comes from the egg and sperm which do not give it bacteria.

Only during birth, when the sac is broken and the baby emerges does it encounter bacteria.

Example for gram ve bacteria?

Gram positive bacteria have a thick layer of peptidoglycan in their cell wall, which retains the crystal violet stain in the Gram staining process, causing them to appear purple under the microscope. Examples include Staphylococcus aureus and Streptococcus pyogenes.

What IS Golden Staph and how do you get it?

Golden Staph is a common nickname for Staphylococcus aureus, a type of bacteria that can cause infections. It is often found on the skin and in the nose of healthy individuals without causing harm. Staph infections can occur when the bacteria enter the body through cuts, wounds, or medical devices, leading to skin infections, pneumonia, or more serious conditions like blood poisoning.

What are A natural substance which kills bacteria can be broad spectrum or specific?

An antibiotic is a natural substance that kills bacteria and can be broad spectrum, effective against a wide range of bacteria, or specific, targeting only certain types of bacteria. Examples of broad-spectrum antibiotics include penicillin and amoxicillin, while examples of specific antibiotics include vancomycin and azithromycin.

In what ways bacteria is harmful?

bacteria invades organisms, makes them sick and causes disease. bacteria is also really helpful in many was though. for example, bacteria are decomposers. they also fight off bad bacteria and digest food. they are used in medicine and in foods like cheese, yogurt and sour cream. they even are used to produce electricity and are used for botox.

Explain 2 features of bacteria?

1.they do not have a nucleus or organelles

2. they are prokaryotic cells that absorb nutrients from the environment or produce their own nutrients, through light energy or other processes.
