Arguably the most widely known drug-resistant infections is methicillin-resistant Staphylococcus aureus or MRSA. This resistant infection is often associated with hospitals. Others you may have heard of include C. diff (clostridium difficile), drug-resistant malaria and streptococcus pneumoniae.
The bacterial strains staphylococci, enterococci, and pneumococci pose some of the most serious problems in terms of antimicrobial resistance. Scientists have now acquired detailed information about how these bacteria develop drug resistance.
There are three types of public health antimicrobials: sterilizers, disinfectants, and sanitizers.
The high priority category includes bacteria such as Enterococcus faecium and Staphylococcus aureus that are resistant to various antibiotics, such as vancomycin and fluoroquinolones.
MRSA is one of the most common antibiotic-resistant bacteria. Symptoms of MRSA infection often begin as small red bumps on the skin that can progress to deep, painful abscesses or boils, which are pus-filled masses under the skin. These need to be surgically opened and drained.
Antibacterials act against bacteria, antivirals act against viruses, antifungals act against fungi, and antiprotozoals act against protozoa (www.amrls.cvm.msu.edu).

The most common types are bacteria, viruses and fungi. There are also microbes called protozoa.
Endospores are considered the most resistant structure of microbes. They are resistant to most agents that would normally kill the vegetative cells they formed from. Mycobacterial infections are notoriously difficult to treat.
How do healthcare providers treat antibiotic-resistant bacteria? Treatment options are often limited. Providers look for a type of antibiotic, or a combination of medicines, that'll treat your infection. For example, carbapenems are antibiotics that work well against antibiotic-resistant bacteria.
Various microorganisms have medical significance, including bacteria, viruses, fungi, and parasites. Antibiotics are compounds that target bacteria and, thus, are intended to treat and prevent bacterial infections.
The germs are listed in three categories—urgent, serious and concerning—based on level of concern to human health.
There is no one type of antibiotic that cures every infection. Antibiotics specifically treat infections caused by bacteria, such as Staph., Strep., or E. coli., and either kill the bacteria (bactericidal) or keep it from reproducing and growing (bacteriostatic).
The carbapenems, imipenem and meropenem, are considered the most potent of any antibiotic class, and are for use in serious infections or when resistance compromises all other agents.
Antimicrobial resistance mechanisms fall into four main categories: (1) limiting uptake of a drug; (2) modifying a drug target; (3) inactivating a drug; (4) active drug efflux.
Antimicrobial resistance (AR) happens when germs develop the ability to defeat the drugs designed to kill them. AR has the potential to affect people at any stage of life, as well as the healthcare, veterinary and agriculture industries. This makes it one of the world's most urgent public health problems.
Fungal spores and non-enveloped viruses are generally less susceptible. Mycobacteria, bacterial endospores, and protozoal oocysts are highly resistant to most disinfectants.
Strains of pathogens that've developed resistance to multiple drugs are the hardest to get rid of. Infections like MRSA and CREs are often resistant to more than one type of antibiotic, so finding one that's effective (or a combination of medications that work together) can be challenging and take a long time.
