Staphylococcal wound infections are treated with antibiotics. Methicillin-resistant Staphylococcus aureus (MRSA) may not be effectively treated by antibiotics alone. Once a MRSA infection is suspected, antibiotics are no longer effective, and a surgical debridement and closure of the wound is necessary to eradicate the MRSA infection.
The main cause of MRSA infection is the presence of the organism in the nasal mucosa. When nasal mucosa becomes inflamed, the bacteria are able to survive and multiply in the host's body. MRSA is usually spread through breaches in mucous membranes and contact with objects that contain the organism. When MRSA bacteria infect the skin, they can stay there for hours or even days and are easily spread. In the community, MRSA may be spread through saliva on teeth from people in close contact.
Approximately 10 million Americans have had a hospital-acquired staphylococcal infection each year. In contrast to skin infection, this review shows that the number of infections per patient is much higher than per patient for gastrointestinal infections.
MRSA is an opportunistic human pathogene that can cause serious illnesses in susceptible hosts. It is responsible for about 55 percent of hospital infections among the immunocompromised, and can be found in a variety of settings and conditions. Many studies on MRSA have been conducted to better understand the biology of this microorganism and its potential hazards to human health. However, it is only recently that MRSA had entered the research agenda. This article describes the microbiology, pathogenesis, and epidemiology of MRSA and its importance in medicine and healthcare.
Signs of MRSA, and the risks associated with MRSA, include increased frequency of skin lesions, such as boils, abscesses, eczema, and gangrene. Additionally, MRSA infections may be related to the spread of infection from the skin to the bloodstream. MRSA can also cross the blood-brain barrier into the brain where it may cause brain damage or infection. Lastly, MRSA is often spread through an infected catheter.
Without further research, there is currently no way to cure MRSA. However, with current treatments, significant outcomes have been demonstrated in trials such as VOCAER trial. However, further research is necessary to develop more effective and more targeted antibiotics.
Because our study demonstrates an association between MRSA carriage and S. aureus carrier status, we recommend a systematic screening of family members of MRSA carriers to detect carriers early and offer appropriate treatment.
In this case, all we can give our patients is vancomycin for life, although we use a different approach to treatment because we acknowledge that the emergence of vancomycin resistance has increased.
The age range of individuals being treated in the United States is 15.7 to 49.2 years, with an average age of 31.0 years. Infected males are more prone to having serious complications. Males are more likely than females to have complicated mrsa infections. Children infected with MRSA are younger than those infected with S. aureus. When MRSA is the sole pathogen found, males, ages 15 and over, have more severe disease compared with female and younger patients. Infected children with mrsa are more prone to complications. M. uber septicemicus is more common in males and adults over the age of 50 years. M.
Vancomycin is capable of inactivating virtually all strains of gram positive pathogens including MRSA. It is probably the most active of all penicillins known in the USA, and is routinely considered as the drug of choice for MRSA infections. While there is a long history of use of vancomycin, there is no clear evidence of its efficacy against MRSA. It may be more effective against MRSA strains that express vancomycin resistance genes, which is a relatively infrequent occurrence. Another possible explanation for inconsistencies in its efficacy might be the low potency of vancomycin against MRSA. Thus, more research on this compound and other antibacterial agents and their efficacy on MRSA must be conducted.
Pharmacokinetic and pharmacodynamic properties are being improved by increasing the oral bioavailability of this drug. It is the oral bioavailability of a drug that is a key indicator of its therapeutic efficacy, and the oral bioavailability of vancomycin is being increased by improving its dissolution and absorption from the gastrointestinal tract.
