Nonetheless, for the basis of the human treatment in clinical microbiology, it is fundamental to group bacteria according to their vulnerability to specific drugs as it enhances the ease of management of an illness. Therefore classification is critical in the enhancement of human treatment.
Full Answer
What is the purpose of classification of bacteria?
Bacteria are classified and identified to distinguish among strains and to group them by criteria of interest to microbiologists and other scientists. Nomenclature Bacteria are named so that investigators can define and discuss them without the necessity of listing their characteristics.
What is the best approach to bacterial taxonomy?
In practice, the approach to bacterial taxonomy should be polyphasic (Fig. 3-3). The first step is phenotypic grouping of strains by morphological, biochemical and any other characteristics of interest.
What is a primary distinguishing characteristic of bacteria?
A primary distinguishing characteristic is whether an organism grows aerobically, anaerobically, facultatively (i.e., in either the presence or absence of oxygen), or microaerobically (i.e., in the presence of a less than atmospheric partial pressure of oxygen). The proper atmospheric conditions are essential for isolating and identifying bacteria.
How are organisms classified for classification purposes?
For classification purposes, organisms are usually organized into subspecies, species, genera, families, and higher orders. For eukaryotes, the definition of the species usually stresses the ability of similar organisms to reproduce sexually with the formation of a zygote and to produce fertile offspring.
Why is classification of bacteria important in medicine?
Doctors classify bacterial infections based on the various ways they classify the bacteria. For example, infections may be classified as caused by gram-negative or by gram-positive bacteria. This distinction is important because treatment of the two types may require different types of antibiotics.
How can bacteria be used to treat human diseases?
Gut bacteria have been altered to produce therapeutic molecules to treat metabolic conditions, kill pathogens and trigger immune responses to cancers. A strain of Escherichia coli engineered to produce the proteins needed to correct rare metabolic deficiencies is now in clinical trials.
Why do bacteria plays an important role in human disease and in health?
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].
How are bacteria classified in medicine?
The classification of bacteria is based on various criteria, such as the nature of the cell wall, staining characteristics, ability to grow in the presence or absence of oxygen, and ability to form spores. The criterion currently used is the base sequence of the genome DNA.
Can we use bacteria to improve health?
A plant-based diet can improve health and prevent disease by feeding the good bacteria in your digestive tract. Trillions of bacteria live in your digestive tract and play an important role in health.
What is a beneficial use for bacteria of the microbiome in treating disease?
The bacteria in the microbiome help digest our food, regulate our immune system, protect against other bacteria that cause disease, and produce vitamins including B vitamins B12, thiamine and riboflavin, and Vitamin K, which is needed for blood coagulation.
Why are bacteria important to humans economically?
Bacteria are economically important as these microorganisms are used by humans for many purposes. The beneficial uses of bacteria include the production of traditional foods such as fudge, yogurt, cheese, and vinegar. Microbes are also important in agriculture for the compost and fertilizer production.
What is the importance of bacteria?
Bacteria play important roles in the global ecosystem. The cycling of nutrients such as carbon, nitrogen, and sulfur is completed by their ceaseless labor. Organic carbon, in the form of dead and rotting organisms, would quickly deplete the carbon dioxide in the atmosphere if not for the activity of decomposers.
What is bacterial classification?
Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters.
Why is bacteriology important in medical technology?
The primary mission of the clinical bacteriology laboratory is to assist the health care provider in the diagnosis of infectious diseases. Due to the variety of specimens submitted to the bacteriology laboratory, many of the steps related to the processing and workup of a specimen have remained manual.
Which reason best explains why bacteria are good at causing infections in other organisms?
Which reason best explains why bacteria is good at causing infections in other organisms? Bacteria are transmitted easily and reproduce quickly.
