Cattle can catch a disease that destroys the villi. How does this effect them?

They can die from this disease.

NO its not going to kill everybody if it keeps as it is at the moment.\nYou can get it just by contact with sick animals.\nBut this kind o virus can change behavior. \nThat was what happened in 1918 in the Spanish flu.\nSee in\nhttp://www.therealleiman.com/history.html\nIf that happens now with this virus \nWell , ....let us hope its not going to happens.

They have only one real purposre.  First, they dramatically increase the total surface area of your small intestines to help absorb nutrients.  That's why when you get sick and get diarrhea, it's because the illness (virus,bacteria, etc.) has destroyed those villi and decreased the surface area of your intestine and all the stuff you eat just goes right through you.  Second, they say that it assists with motility (moving stuff through) but that isn't really true. You have muscles around your intestines that squeeze in a rythmic pattern and slowly push through section by section.

They can kill off plants or animals that other animals compete with causing an overpopulation of that species. Or they can introduce a new species into a previously stable ecosystem. The new species may have no competition in the new environment and may overpopulate or it may eat another species and wipe it out.

All animals can carry bacteria, so this could be possible, but the doctors should be able to detect this.  Best of luck.

They have their own STD. \n\nBut thinking more about your question, I would say I do not know. Because too little humans are sick zoophilics, who could try this way, no material for big generalisations. Besides they had to be bi- in certain sense, for could catch a disease afroma human nd transmit it to animal... \n\nSome theories say that HIV passed from apes, so why some viruses and microbes could not do be passed (including mutations) to animals? Really probable thing.

You probably mean "why can't we kill viruses?" Right?\n\nThe problem is that viruses tend to live inside host cells. To destroy the virus you need to destroy the cell.  Viruses also modify cell receptors so they can't properly work, which limits the ability to find something that can both penetrate the cell and kill the virus without damaging the functions of the cell.

all viruses work by taking over the reproductive mechanism of cells and making them manufacture copies of themselves.  Frequently the viral cells put out toxins that cause various illnesses.  "Stomach" viruses do this in the GI tract.

It depends on the state you are in.  I live in a cattle state as well.  You cannot kill cattle, because of property destruction and animal cruelty.  Your can however, contact local authorities and find the owner, and make them replace your fence and landscaping.

I too am a zoology major (science grad) and cows have a stomach with 4 chambers; rumen, reticulum, omasum and the abomasum. The cow ingests food and masticates it to break the cell wall. After entering the first two chambers, the cow regurgitates the cud to further break down the food (fibres); this assists the body in accessing nutrients within the cell which are difficult to obtain due to the nature of plant cells. These chambers contain bacteria (symbiotic) that break down cellulose. The liquid pulp then passes into omasum, which removes water. Finally the food enters the true stomach, abomasum which acts like any typical stomach. Cows should actually be known as bacteriophages, simply because its actually the bacteria that gain all the energy and nutrients required...

It is a protective measure.  If the virus has mutated, the handler takes a risk of becoming infected by the virus. There are also other diseases that birds may carry that can infect humans.\n\nCooking infected meat kills the virus, so it no longer poses any real danger.  And yes, if you're planning on preparing a chicken that was infected, it would be a good idea to suit up.  Keep in mind though, that most birds that enter the food supply are not infected, or did not die as a result of being infected.  Birds that die before being slaughtered are not used for human consumption (not in the U.S., anyway).  These birds are either destroyed, or in some cases used for pet food.

The excreta and saliva  of birds contain the virus.They get dried up on earth.Contamination of these with food is one way.Birds are not boiled but only fried.This does not destroy virus.Eating ill cooked birds is another way.

A phagocyte will engulf the bacteria, in the phagocyte, like a macrophage, there is a cell organell called a lysosome. In the lysosome are powerful hydrolytic enzymes. In the phagocyte the lysosomes fuse with the bacterial vesicle and the enzymes destroy the bacteria. This by the way does not work for the bacteria that causes TB.\na cell can produce a protein and exocytose the protein in a pinched off part of the plasma membrane called a vesicle.The final packaging of the protein is done by the golgi apparatus in the cell.\nActive transport is transport that uses energy. the energy source used is ATP produced by the mitochondria in the cell. A prime example of active transport is the sodium/potassium pump each living cell employs.

No\n\n"Vitiligo (vit-ill-EYE-go) is a pigmentation disorder in which melanocytes (the cells that make pigment) in the skin, the mucous membranes (tissues that line the inside of the mouth and nose and genital and rectal areas), and the retina (inner layer of the eyeball) are destroyed. As a result, white patches of skin appear on different parts of the body. The hair that grows in areas affected by vitiligo usually turns white."\n\nCause is still unknown\n\n"Leprosy is a chronic infectious disease which attacks the skin, peripheral nerves and mucous membranes (eyes, respiratory tract). Leprosy is also known as Hansen's disease because the bacillus which causes it was discovered by G.A. Hansen in 1873. It is most common in warm, wet areas in the tropics and subtropics."\n\n"Leprosy is characterized by multiple lesions accompanied by sensory loss in the affected areas. Usually, sensory loss begins in the extremities (toes, fingertips). In many advanced cases, gangrene sets in, causing parts of the body to "die" (necrosis) and become deformed."

I totally agree with your thinking on the first two, I have often made the Cinderella argument myself. However, mad cow disease is a real thing, BSE - Bovine (meaning cows) Spongiform Encephalitis. Encephalitis is a form of brain disease, hence the 'mad' element. The human variant is CJD - Creutzfeldt-Jakob Disease, and can be caught from eating contaminated meat.

Cows give bacteria an appropriate microenvironment to develop and grow, well protected from the harsh conditions of the outside environment. The bacteria also get enough food to live. \nIn return, bacteria process the cellulose present in plants (which mammals can´t digest) into simpler sugars that can be absorbed and utilized by the cow as an energetic source.
