Colorized scanning electron micrograph of a human neutrophil ingesting MRSA. Methicillin-resistant Staphylococcus aureus (MRSA) is a group of gram-positive bacteria that are genetically distinct from other strains of Staphylococcus aureus. MRSA is responsible for several difficult-to-treat infections in humans.
Although S. aureus can be present on the skin of the host, a large proportion of its carriage is through the anterior nares of the nasal passages [2] and can further be present in the ears. [129] The ability of the nasal passages to harbour S. aureus results from a combination of a weakened or defective host immunity and the bacterium's ability ...
The anterior nares can act as a colonizing point from which the infection can spread. [2] This can be particularly troublesome if the strain is an antibiotic-resistant (commonly MRSA or ORSA) strain. MRSA (first discovered in the UK in 1961) has become particularly widespread in hospitals and is commonly considered a super bug.
In one study, 30 percent of patients with MRSA thought the infection was a spider bite). Remember, if you don’t live in the states where brown recluses live, it’s probably not a brown recluse ...
Problematically, methicillin-resistant Staphylococcus aureus (MRSA) has become a major cause of hospital-acquired infections. MRSA has also been recognized with increasing frequency in community-acquired infections. [7] The symptoms of a staphylococcal infection include a collection of pus, such as a boil or furuncle, or abscess.
“Symptoms also may not be as bad at night,” Dr. Coleman says. But if you’ve been dealing with a cough for a while, or if it feels like your cough is getting worse, he says it’s time to see ...
Here are the symptoms to look for, plus how long you're contagious for, per an infectious disease doctor. Norovirus cases are surging in the US, the CDC says. Here are the symptoms to look for ...
Although the disease is easily treatable, in severe cases boils may form inside the nostrils, which can cause cellulitis at the tip of the nose. The condition becomes serious because veins at that region of the face lead to the brain, and if bacteria spreads to the brain via these veins, the person may develop a life-threatening condition called cavernous sinus thrombosis, which is an ...
