Advantages and disadvantages of Bacteria? Biology Q&A? ›

Most types of bacteria aren't harmful; many are even helpful. They make up your microbiome, which keeps your gut healthy. Other bacteria, called pathogens, can cause infections that require treatment. Healthcare providers can prescribe antibiotics to treat many of these infections.

Dysbiosis of the gut bacteria communities can cause many chronic diseases, such as inflammatory bowel disease, obesity, cancer, and autism.

Bacterial expression system

Disadvantages of this system include difficulty in expressing some mammalian proteins, accumulation of proteins as inclusion bodies, protease contamination from host proteins leading to degradation of expressed protein, and also endotoxin accumulation.

Most bacteria are good for us

The bacteria in our bodies help degrade the food we eat, help make nutrients available to us and neutralize toxins, to name a few examples[7]; [8]. Also, they play an essential role in the defense against infections by protecting colonized surfaces from invading pathogens[8]; [9].

But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick.

This can make genetic manipulation difficult and time-consuming. Additionally, the presence of plasmids and other extrachromosomal DNA can complicate genetic engineering efforts. Bacteria also have the potential to be pathogenic. While many bacteria are harmless, some can cause disease in humans, animals, and plants.

Bacteria break down (or decompose) dead organisms, animal waste, and plant litter to obtain nutrients. But microbes don't just eat nature's waste, they recycle it. The process of decomposition releases chemicals (such as carbon, nitrogen, and phosphorus) that can be used to build new plants and animals.

What are the advantages of bacteria on a biological basis? ›

Bacteria refer to unicellular microscopic organisms that generally lack a distinct nucleus. Bacteria assist in digesting food in the large intestine. Some bacteria produce antibiotics, drugs, and vaccines. Vital vitamins and nutrients can be synthesized using bacteria.

Bacteria cause many common infections such as pneumonia, wound infections, bloodstream infections (sepsis) and sexually transmitted diseases like gonorrhea. Moreover, they have been responsible for several major disease epidemics.

FATTOM is an acronym used to describe the conditions necessary for bacterial growth: Food, acidity, time, temperature, oxygen, and moisture. Foods provide a perfect environment for bacterial growth, due to their provision of nutrients, energy, and other components needed by the bacteria.

Complications of bacterial infections

It's important to seek treatment because untreated bacterial infections can lead to serious problems. For example, an untreated infected cut can cause cellulitis, a spreading skin infection. Untreated bacterial infections can sometimes lead to serious, life-threatening conditions.

Transformation of environmental DNA can provide bacteria with a means to adapt quickly to a changing environment. While this can benefit microbes by facilitating the spread of antibiotic resistance, it can also be harmful if it causes the loss of beneficial alleles from a population.

The bacterial culture is also useful in producing effective antibodies and other pharmaceutical products. This research is conducted to find out how far the methods of cell culture processes used in medical laboratories are effective in deriving the desired level of outcomes from the bacterial culture.
