Bacteria

The yeast used in baking is

Kingdom:Fungi

Phylum:Ascomycota

Subphylum:Saccharomycotina

Class:Saccharomycetes

Order:Saccharomycetales

Family:Saccharomycetaceae

Genus:Saccharomyces

Species:S. cerevisiae

However, yeast itself is can't be classified further than the kingdom yeast because it encapsulates a large amount of diverse organisms. http://en.wikipedia.org/wiki/Saccharomyc...

All animal, humans, insects, carpet, furniture, personal belongings, dirt, sand, toilets, pools.

bacteria are divided in three type acording to temperature tolerance

thermophilic bacteria that grow in extremlly termall gaizers.

mesophilic bacteria that grow 20 and 45 °C (68 and 113 °F)

psychophile macteria that growth −15°C to +10°C.

most of bacteria are mesophilic that it doesent meaan thay grow from 20 to 45 °C (68 and 113 °F)

One rare role of bacteria is their ability to produce antibiotics. Some bacteria species can produce compounds that inhibit the growth of other bacteria, fungi, or even viruses. This natural antibiotic production is not common among bacteria, making it a rare and valuable trait.

Spores are a dormant, protected form of bacteria that can withstand harsh conditions, while vegetative bacteria are actively growing and reproducing. Spores are highly resistant and can survive for long periods, while vegetative bacteria are more vulnerable to environmental stresses. Spores can germinate and grow into vegetative bacteria when conditions become favorable.

Its really simple if you think about it. if you have a bacterial infection your white blood cell count would increase because as the wbc's are fighting off the infection they die off releasing a chemical into the blood stream that tells your body to increase production of white blood cells. so the hematocrit would have a thicker buffer layer. the buffer layer being the white blood cells. With a higher production of white blood cells the rbc production would very slightly decrease which would decrease the ratio of rbc to whole blood volume.

The primary bacteria that causes acne is Propionibacterium acnes. It is a normal part of the skin microbiota but can contribute to acne when it multiplies excessively in hair follicles, leading to inflammation and the formation of pimples.

Firstly, many bacteria are pathoges, and so can directly cause disease. For example, the bacteria known as Salmonella causes food poisoning.

Secondly, bacteia compete with us for food, and so tend to eat the food which we eat, there by making it unedible for us.

Anthrax is a bacterium that has been used in the past as a biological weapon. It produces toxins that can be lethal when inhaled or ingested. Other bacteria such as Yersinia pestis (plague) and Francisella tularensis (tularemia) have also been associated with bioterrorism.

Chlorine is a greenish-yellow gas that is known for its antibacterial properties and is commonly used as a bleaching agent in various industries.

The oxidative-fermentative test is used to determine if gram-negative bacteria metabolize carbohydrates oxidatively, by fermentation, or are nonsacchrolytic and therefore have no ability to use the carbohydrate in the media.

The bacteria commonly associated with diseases in lime fruits is Xanthomonas citri, known to cause citrus canker. This bacterium infects the plant through wounds and natural openings, causing lesions on leaves, stems, and fruit. Control measures include pruning infected branches and using copper-based sprays.

Bacteria such as Bacillus cereus, Clostridium perfringens, and Staphylococcus aureus are common culprits for contamination in starchy foods like rice, potatoes, and pasta. These bacteria can produce toxins that cause food poisoning when the contaminated food is consumed. Proper storage, handling, and cooking techniques can help prevent contamination by these bacteria.

It happens when the manure containing E. coli is used for fertilizer (a common practice to help crops grow) or if water contaminated with E. coli is used to irrigate the crops. Cows or other animals that eat the crops that was infected can infect the animals.

The white blood cells react to recognise, engulf and destroy the invading cells.

There arw also lymphocytes and T-Cells and B-Cells which are activated with sensors so that Attatch to specific antigens. The T-Cells tell the B-Cell what shape antibody they need to attatch to the antigen on the invading cell. When all teh antigens on the invadingcell are sruck to a antibody the cell has been engulfed and destroyed. The cells also make copies(memory cells) of the antigens so that the will recognise and react fast as they already have the right antibodies prepared.

However - some virus' etc mutate (such as flu) so when this invades a second timethe antigens are different and the body doesn't recognise it and has to behin the process from start.

No. Pasteurization is designed so that the quick heating and cooling kills these harmful bacteria "spores" that come with milking cows. Bacteria are not found in the udder or teat, rather just as the milk enters from the teat.

Measles is a viral infection caused by the measles virus, which primarily infects and replicates in immune cells such as T lymphocytes and macrophages in the respiratory system.

They are Gram-negative bacteria; they photosynthesize in the same manner as plants and are believed to be responsible for first introducing oxygen into primitive atmosphere. If care is not taken in disposing of industrial, agricultural, and human wastes, phosphates drain into lakes and ponds resulting in a "bloom" of these organisms. The surface of the water becomes turbid, and light cannot penetrate to lower levels. When a portion of cyanobacteria die off, the decomposing prokaryotes use up the available oxygen, causing fish to die from lack of oxygen

Bacteria Certain bacteria can use nitrogen from the air to make nitrogen-containing substances called nitrites. Other bacteria can turn nitrites into nitrates-another group of nitrogen-containing substances.

Some heat-resistant organisms include thermophiles like bacteria of the genus Thermus and archaea of the genus Pyrococcus. These organisms have adapted to extreme temperatures, such as boiling hot springs or deep-sea hydrothermal vents, and can survive in these harsh conditions.

Mercurochrome acts as an antiseptic that can inhibit the growth of bacteria by disrupting their cell membranes and interfering with their metabolic processes. This can lead to the death of the bacteria and ultimately help in preventing infection. However, it is important to note that the use of Mercurochrome has been limited due to concerns about its mercury content.

Blood agar medium is commonly used for the isolation and identification of Staphylococcus aureus due to its ability to differentiate between various types of staphylococci based on their hemolytic patterns. Staphylococcus aureus typically produces beta-hemolysis on blood agar, creating a clear zone around the colonies. Additional biochemical tests such as coagulase testing can further confirm the identity of Staphylococcus aureus.

Bacteria can decrease in number due to factors like lack of nutrients, changes in environmental conditions (such as temperature or pH), competition with other microorganisms, exposure to antibiotics or disinfectants, and the immune response of the host organism.

Exposure to snow alone is not sufficient to kill viruses or bacteria on bloody tissue. Proper cleaning and disinfection using appropriate agents and techniques are necessary to effectively remove and kill microorganisms on contaminated tissue.
