Which EM waves can kill bacteria on food and surgical tools?
EM waves like X-rays and gamma rays are efficient at killing bacteria on food and surgical tools. These are ionizing radiations and cause breaks in the DNA of the organisms. On sufficient exposure, the breaks are irreparable and the bacteria on the food and surgical tools are killed.
You are probably asking about Cloxacillin. This is a prescription drug used as an antibiotic of the same type as penicillin. It is partially synthetically produced. (Do not use if you have an allergy to penicillin.)
Brand names of this antibiotic include: Cloxapen, Cloxacap, Orbenin, and Tegopen.
What is the term for an infection of the middle ear caused by a bacteria or virus?
Otitis media is the term used for an infection of the middle ear. Oti- means ear; -tis means inflammation and med- means middle. This infection occurs between the tympanic membrane (ear drum) and the inner ear. Either bacterial infections, which include Staph, or viral infections, due to Influenza, are causes. Fungal infections also occur.
What protects your hands better from bacteria handgloves or handsantizer?
Gloves always are better than a hand sanitizer. Constant use of sanitizers can and does produce resistant forms of bacteria. It is better to use soap and water at home and to use the sanitizer if you are working in a clinical setting.
What bacteria produces enterotoxins?
Several bacteria produce enterotoxins, including Staphylococcus aureus, Clostridium perfringens, Vibrio cholerae, and Escherichia coli. These enterotoxins can cause gastrointestinal illnesses, such as food poisoning and diarrhea, when ingested.
Does b burgdorferi produce endospores?
B. burgdorferi is a spirochete and doesn't produce endospores. It is the cause of Lyme's Disease which is carried by a tick. The microbe is found in the saliva of the tick. It is passed with the bite of the tick.
Contains bacteria that feed on material passing through?
This describes the bacterial flora found in the intestines, which includes both beneficial and harmful bacteria. The beneficial bacteria help in the digestion of food and the absorption of nutrients, while also playing a role in supporting the immune system.
Are mitochondria associated with bacterial cells?
No, mitochondria are only present in eukaryotic cells. Bacteria are prokaryotic cells.
When bacteria form in strings they are called?
If it's a string of circular bacteria it's a chain of cocci (spherical) bacteria.
What is the function streptococcus?
Any and all bacteria are part of the normal ecosystem. Their main function is to act as decomposers. These break down other organisms into nutrients that will be recycled.
Which bacteria grow in the betadine?
Burkholderia cepacia complex (BCC) is a group of catalase-producing, lactose-nonfermenting, Gram-negative bacteria composed of at least 17 different species, including B. cepacia, B. multivorans, B. cenocepacia, B. vietnamiensis, B. stabilis, B. ambifaria, B. dolosa, B. anthina, and B. pyrrocinia.B. cepacia is an important human pathogen which most often causes pneumonia in immunocompromised individuals with underlying lung disease (such as cystic fibrosis or chronic granulomatous disease).It also attacks young onion and tobacco plants, as well as displaying a remarkable ability to digest oil.
Pathogenesis
BCC organisms are typically found in water and soil and can survive for prolonged periods in moist environments. Person-to-person spread has been documented; as a result, many hospitals, clinics, and camps have enacted strict isolation precautions for those infected with BCC. Infected individuals are often treated in a separate area from uninfected patients to limit spread, since BCC infection can lead to a rapid decline in lung function and result in death.
Basic Concepts for Micro Specimen Collection
1. Universal precaution guidelines must be followed for collection and transport of all specimens. Specimens should be placed in tightly sealed containers; the containers should be free of any external spillage, and the specimens should be transported in bags.
2. Collect the specimen from the actual site of infection, avoiding contamination from adjacent tissues or secretions.
3. Collect the specimen at optimal times (i.e. early morning sputum for AFB culture).
4. Collect a sufficient quantity of material.
5. Use appropriate collection devices: sterile, leak proof specimen containers. Use appropriate transport media. (Anaerobe transport system Amies or Stuart's for bacterial cultures, Cary-Blair for stool culture, M4 for viral and chlamydia cultures.)
6. Whenever possible, collect specimens prior to administration of antibiotics or antivirals.
7. Properly label the specimen including the date, time, and initials of collector. The source of specimen is required.
8. Minimize transport time. Maintain an appropriate environment between collection of specimens and delivery to the Laboratory.
9. If appropriate, decontaminate the skin surface. Use 70-95% alcohol (ALC) and 1-2% tincture of iodine (TIO) or chloroprep containing chlorhexidine gluconate 2% and isopropyl alcohol 70% to prepare the site. Allow a contact time of two minutes to maximize the antiseptic effect.

Will microwaving a wet sponge for 2 minutes kill all the bacteria and germs?
Microwaving a wet sponge for 2 minutes can help kill some bacteria and germs, but it may not eliminate all of them. It is more effective to regularly replace sponges or clean them by soaking in a bleach solution and allowing them to air dry.
What pH and water activity (aw) levels do bacteria grow best?
pH levels vary among bacterial species. For example; acidophillic bacteria grow best at low pH. While alkalophiles grow better at alkaline (high) pH. Most bacteria grow best at high aw (>0.90). While few bacterial species such as xerophiles grow best at an aw of 0.6-0.7
How many healthy food handlers carry dangerous bacteria that could spread to the food they serve?
It is estimated that about 1 in 6 food handlers may carry dangerous bacteria that could potentially spread to the food they serve. Proper food safety practices and hand hygiene are crucial in preventing the transmission of pathogens to food.
Why does hydrogen peroxide kill bacteria but not human skin cells?
Hydrogen peroxide kills bacteria by generating reactive oxygen species that damage bacterial cell membranes and proteins. Human skin cells contain enzymes like catalase that break down hydrogen peroxide into water and oxygen, protecting them from its harmful effects. This allows human skin cells to survive exposure to hydrogen peroxide while bacteria cannot.
Do bacteria adapted better life on the earth than human beings?
Perhaps as bacteria have been around millions of years longer than humans.
Which of these patrol the body seek out invaders destroy bacteria and aid in immunity?
White blood cells
*shall and no question mark at the end..
What is the bacteria which has the longest incubation period in intestinal infection?
Parasitic infections have the longest incubation period in an intestinal infection. One in particular such as the Giardia infection has an incubation period of one to as many as four weeks.
What is bigger bacteria or viruses?
In this case, bacteria can grow more and divide into more organisms, but fungus, however, can grow into mushrooms that are bigger than organisms. so in opinion, it is fungus.
Are bacteria considered simple organisms why or why not?
Bacteria are considered simple organisms because they are single celled, they do not have a nucleus with a membrane and no membrane-bound organelles.
