MRSA ST398

MRSA ST398 is a strain of the gram-positive bacterium Staphylococcus aureus, which belongs to the genus Staphylococcus. This genus covers a large group of gram-positive bacteria that are classified taxonomically in the family Staphylococcaceae, order Bacillales, class Bacilli, and phylum Firmicutes. ==Discovery==

MRSA ST398, a new strain of MRSA, was first found in 2003, in Dutch hospitals. The bacteria was found specifically in people who were frequently in contact with livestock, particularly pigs and veal calves. A study from a Dutch farm found that most of the MRSA strains found in livestock and humans were of the CC398 isolate. The study also found that the closer people lived to a livestock farm, the more cases of MRSA ST398 were found. Since then, the strain has also been detected in many other regions of the world. ==Transmission==

The primary method of transmission of MRSA ST398 is through contact with infected animals, which classifies it as a zoonotic agent. People who work with livestock or live in close proximity to them are the most vulnerable to the infection. In healthcare settings, people with open wounds are most susceptible to the infection. Therefore, to prevent transmission, wounds should stay covered and infected patients should not be near each other. As a zoonotic agent, MRSA ST398 can be transmitted from animal to human, human to animals, and human to human, which is an important factor when considering mitigation protocol. Transmission of MRSA ST398 is similar to that of MRSA. MRSA ST398 has an enhanced biofilm formation ability, which increases the survivability of the bacteria and increases its virulence. This increases the fitness of MRSA ST398 in the community and even in the healthcare settings, which poses a severe threat to public health. ==Infection==

Symptoms and signs MRSA ST398 infection symptoms are similar to those of other MRSA infections. This includes skin infections, abscesses, sores, and pneumonia. In severe cases, MRSA ST98 can lead to sepsis and death. Prevention Patient education is a critical component of treatment and prevention. Clinicians are encouraged to educate patients, caregivers, and household members on methods to limit further spread of MRSA in the community. This includes maintaining adequate hygiene and keeping wounds covered with clean, dry bandages. Infected persons should also be excluded from activities that involve close contact with others. Before treatment, prevention is incredibly important to prevent the spread of the MRSA strain. This involves practicing good hygiene and infection control measures, particularly in healthcare settings and for those who work closely with livestock. However, hospitalization and aggressive treatment to treat the symptoms of MRSA ST398 can be employed. And until more information about antimicrobial susceptibilities are known, the ST398 strain should be treated as MRSA is. == References ==
