MDR Full Form
What is the full form of MDR?
The term "multiple drug-resistant" refers to the inability of some microorganisms, such as bacteria, viruses, and fungi, to be treated with antimicrobial medications. Antimicrobial agents are another name for these antimicrobial medications. Multiple drug-resistant organisms are those that are resistant to three or more kinds of medicines. Antimicrobial categories are a group of medications that have similar effects or target groups of organisms. Multiple drug-resistant strains pose a major risk to the public's health.

There are two more words that are frequently used in this sentence. They are both pan drug-resistant (PDR) and extensively drug-resistant (XDR). The absence of susceptibility of the bacteria to all drug categories, with the exception of one or two, is known as extensive drug resistance.
Microorganisms that are resistant to all drug classes and the medications included within them are said to have pan drug resistance.taetae
Multidrug resistant tuberculosis is one of the MDR category's more prevalent illnesses.
Causes For Multidrug Resistance
Currently, it has been found that a number of microorganisms show multiple medication resistance. The fact that these bacteria can now pass on their resistance to other bacteria that are related to them is one of the significant problems with this. Cell-cell conjugation, a process that causes this to occur.
They are no longer dependent on the cell wall's glycoproteins.
Antibiotic deactivation
It becomes less permeable for antibiotics to pass through cell walls (the cell walls do not allow antibiotics to enter the cells of the microorganisms thus not allowing the antibiotics to kill the organism)
These organisms acquire the ability to throw out the infused antibiotics.
They go through severe mutations.
Antimicrobial resistance mechanisms can be divided into four primary groups: (1) decreasing medication uptake; (2) altering drug targets; (3) rendering drugs inactive; and (4) active drug efflux. Limiting drug uptake, drug inactivation, and drug efflux are examples of intrinsic resistance strategies; drug target modification, drug inactivation, and drug efflux are examples of acquired resistance strategies. There are variances between the sorts of mechanisms used by gramme positive and gramme negative bacteria due to structural differences, among other things.
Additionally, a type of fungus called Candida has developed resistance to a particular class of medications.
Origin Of Resistance
Bacteria as a class or species are not always equally vulnerable to or resistant to a given antibiotic. Within bacterial groups that are closely related, resistance levels might vary substantially. The least drug concentration necessary to stop bacterial growth is known as the minimum inhibitory concentration, or MIC, and it is used to determine both susceptibility and resistance. The range of average MICs for a specific antibiotic across the same bacterial species makes up the susceptibility in actuality. A species is deemed to have intrinsic resistance to a medicine if its average MIC falls within the range of resistance. The degree of resistance will vary based on the species and the genes gained, as bacteria may also acquire resistance genes from other related organisms.
Prevention Of Multidrug Resistance
Antimicrobial resistance has been hypothesized to be limited by:
Use the proper antibiotic for the ailment; do not use antibiotics for viral illnesses, for example.
Whenever feasible, pinpoint the pathogenic organism
Choose an antibiotic that specifically targets the bacterium rather than depending on a broad-spectrum antibiotic.
Complete the necessary amount of antimicrobial therapy (not too short and not too long)
Use the right dosage for eradication; as evidenced in food animals, subtherapeutic treatment is linked to resistance.
