Final answer:
The statement about the genus Staphylococcus being gram-positive cocci and developing antibiotic resistance is true. These bacteria are common on the human body and certain strains, like MRSA, are particularly concerning for public health.
Step-by-step explanation:
The statement 'The genus Staphylococcus includes gram-positive cocci that are abundant on the human body surface. Also of great significance is the ability of this organism to develop antibiotic resistance' is true. Members of the genus Staphylococcus, namely Staphylococcus epidermidis and Staphylococcus aureus, are facultative anaerobes, halophilic, and nonmotile. They appear in grape-like clusters under microscopic examination and frequently colonize the human skin and mucous membranes.Of particular concern is Staphylococcus aureus, which can cause serious skin infections and other health issues. Some strains of Staphylococcus aureus, such as methicillin-resistant Staphylococcus aureus (MRSA), have developed resistance to multiple antibiotics, posing a significant challenge to healthcare. These resistant strains are particularly problematic because their surface antigens vary, which can help them evade the immune system and make them difficult to treat.
