Answer: There should be concern because zoonotic diseases passes from an animal or insect to a human very easily, and although they do not always represent a danger, they can cause serious symptoms and even death.
Explanation:
Zoonotic diseases are caused by microorganisms such as bacteria, virus, parasites and fungi, and they can be transmitted between animals and humans. Some examples of zoonotic diseases are Brucellosis, Anthrax and Rocky Mountain Fever (rickettsiosis)
Sometimes, people with zoonotic infections can get very sick and have symptoms such as fever, diarrhea, muscle pain and others. While in other cases, people may have no symptoms and never get sick, without representing a risk
. <u>Besides being important because they can make many people sick, we have to take into account that the way of transmission or propagation can be very simple.</u> Food can be a source of zoonotic infections, for example when farm animals re infected with parasites and these animals are consumed as food. Another example is when people get trichinosis by eating undercooked meat, or consuming fruit without washing it properly, or raw meat from animals infected with the Trichinella parasite. Also, people can get the parasites swimming in a lake if they accidentally swallow water contaminated with the feces of infected animals. Besides, pets can have parasites and pass them on to people, and wild animals can also have infection from parasites that can infect people.
Therefore, we must be concerned about zoonotic diseases, since they can be transmitted very easily from animals to humans, and although they do not always represent a danger, they can cause serious symptoms and even death.
<u>Answer</u>:
Inhibition of host protein synthesis would not be a potential side effect of standard antimicrobial drugs.
<u>Explanation</u>:
Antimicrobial drugs that are specific to inhibit the protein synthesis only target the units of 70S ribosomes. Hence, the ribosomes of eukaryotes remain unaffected. The microbiota present in digestive system is prokaryotic and gets affected by the antibiotics.
Antibiotics can damage the renal tubular cell of the kidney on long term use. As the excretion of toxic drug bi-products and other metabolites takes place from the kidney hence it is highly exposed to these end products.
For example, aminoglycosides have been shown to be nephrotoxic (damaging to kidney), Allergy reactions such as hypersensitivity reactions and anaphylactic reactions such as asthma, coughing, hives are the other side effects of antimicrobial drugs because the cells of immune system recognize these drugs as foreign molecules and attacks them which causes the allergy reactions.
