Explain why the absence of bacteria in the food does not necessarily mean the food is safe to eat.

Biology

svlad2 [7]1 year ago

Even if the bacteria is absent from the food, several fungi, mycotoxins, protozoa me be present in the food.

  • Foods are rarely sterile and often contain natural chemical substances. They contain a diverse population of microbes that come from many sources of the natural micro flora.
  • From the time of harvest to the time of preparation and consumption, microbes contaminate the food.
  • A food's microflora is primarily influenced by the type of microbe, the features of the food, contamination, and the conditions during preparation and storage.
  • Foods may contain bacteria, fungus, protozoa, algae, viruses, and other microbial species.
  • The absence of bacteria does not guarantee that the food is safe to consume because there may still be enterotoxins, mycotoxins, fungi, and other difficult-to-identify microorganisms present.

D.H., a 54-year-old resort owner, has had multiple chronic medical problems, including type 2 diabetes mellitus (DM) for 25 year
Paha777 [63]

Answer:

Chances are, you haven't infected the bacteria in a hospital setting or surgery, as you could have contacted them anywhere.

What happened with said patient was the face of the immunosuppressive treatment, the defense of the patient was decreased and it generated a worse picture with a bacterium that would not act in such a pathogenic way in another person who does not receive corticosteroid treatment.

This deduction could be made since prior to pneumonia and meningitis there were other infections that occurred in the patient indicating immunosuppression or lowered immunity, which were alerts for professionals.

Explanation:

The immunosuppression generated by corticosteroids is an adverse effect of said drug, thus causing bacteria or other pathogenic microorganisms to more easily generate lethal diseases that occur, similar to the human immuno-insufficiency syndrome.

These pneumonias and meningitis are very common in children but not in adults, which means that the defense of acquired immunity throughout life would not be serious.

In patients like these where corticosteroids suppress the path of humoral defense factors, thus inhibiting the presence of COX and thromboxane A2 in the immune lineage, that is why the immunological tests are weakened and the bacteria have more spread or harmful effects such as this patient.

The bacterium does not indicate that it is intra-surgical or hospital-based because of the severity of the disease it triggered, but because the patient is immunosuppressed.

Compare and contrast the genetic material between a bacterium and a fungus. ​
Sati [7]
Bacteria and Fungi come under different categories; the former one is the prokaryotic cell while the latter one is Eukaryotic cells. Apart from this, there are many differences between them like bacteria need a host to live, and they can be autotrophs as well as heterotrophs, whereas fungi grow their own and are heterotrophs which depend on others for their food. Bacteria do not have nuclear membrane enclosing nucleus, while Fungi (eukaryotes) have well- defined nucleus surrounded by the nuclear membrane.
