How do antibiotics affect animals?

After animals have been fed antibiotics over a period of time, they retain the strains of bacteria which are resistant to antibiotics. These bacteria proliferate in the animal. Through interaction, the resistant bacteria are transmitted to the other animals, thus forming a colonization of antibiotic resistant bacteria.

Do antibiotics damage animal cells?

Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors.

What makes animals more susceptible to disease?

Excessive inbreeding (i.e., the mating of related animals) among all domesticated animal species has resulted in an increase in the number of metabolic diseases and an increase in the susceptibility of certain animals to infectious diseases.

Why antibiotics should not be used in farming?

Antibiotic Resistance and Food

Bacteria can spread between animals and in their environments (such as on farms, in animal markets, and during transport). When animals are slaughtered and processed for food, these bacteria can contaminate meat or other animal products.

Why are antibiotics used in animal feed and why is this problematic?

Extensive use of low-level antibiotics in feeds has brought about concern for potential harmful effects due to development of resistant strains of organisms in host animals that might compromise animal as well as human health. Drug resistance in bacteria was observed soon after the introduction of antibiotics.

How do antibiotics help animals grow?

Antibiotics increase the efficiency of animal growth by inhibiting the growth of microbes in the gastrointestinal tract which triggers immune responses in the host (Gaskins et al., 2002).

Why do farmers give antibiotics to healthy animals?

Antibiotics given to farm animals keep them healthy, which makes healthy food. Responsible use of antibiotics in animals leads to an overall decrease in bacteria. Antibiotics help make food safe by keeping animals healthy and reducing bacteria entering the food supply.

How do antibiotics cure disease?

Antibiotics are used to treat or prevent some types of bacterial infection. They work by killing bacteria or preventing them from reproducing and spreading. Antibiotics aren't effective against viral infections, such as the common cold, flu, most coughs and sore throats.

How do antibiotics affect bacterial cells?

Antibiotics disrupt essential processes or structures in the bacterial cell. This either kills the bacterium or slows down bacterial growth. Depending on these effects an antibiotic is said to be bactericidal or bacteriostatic.

How do animals protect themselves from infection?

Physical barriers and the immune system defend an animal's body against organisms that can cause disease. Physical barriers include outer coverings, such as skin, fur, feathers, and scales.

How do animals fight infection?

All animals possess a primitive system of defense against the pathogens to which they are susceptible. This defense is called innate, or natural, immunity and includes two parts. One part, called humoral innate immunity, involves a variety of substances found in the humors, or body fluids.

Why zoonotic disease is important?

Zoonoses are diseases that can be transmitted between animals and people. There are over 200 zoonoses worldwide and more than 60% of known infectious diseases of people are zoonotic. Zoonotic diseases are an important health risk and concern for people and animals.

Why are antibiotics given to livestock?

Why do farmers use antibiotics in livestock production? First, antibiotics are used to prevent, treat and control bacterial infections in livestock. Just like humans, animals can contract infections, such as pneumonia. Antibiotics are used to humanely and economically treat and prevent these diseases.

Why do cattle industries use antibiotics?

Feed and water antibiotics are used in food animal production to treat active infections or illnesses in sick animals, control spread of bacteria within herds that contain sick animals, prevent emergence of illnesses within herds that are at risk of breaking, and historically to promote efficiency of weight gain and ...
