What pylum is MRSA?

Methicillin-resistant Staphylococcus aureus (MRSA) belongs to the phylum Firmicutes. It is a type of bacteria classified under the genus Staphylococcus. MRSA is known for its resistance to methicillin and other antibiotics, making it a significant concern in healthcare settings. This resistance is primarily due to the acquisition of the mecA gene, which alters the target of beta-lactam antibiotics.
