synercid is effective against members of which genera? more than one answer may be correct
□ enterococcus
□ proteus
□ enterobacter
□ staphylococcus
□ pseudomonas

Explanation:

Synercid (quinupristin - dalfopristin) is an antibiotic effective against gram - positive bacteria. Enterococcus, Staphylococcus, and Streptococcus (not listed here, but among the options, Enterococcus, Staphylococcus, and also note that Proteus, Enterobacter, Pseudomonas are gram - negative and Synercid is not effective against them. Wait, correction: Synercid is active against Enterococcus (e.g., vancomycin - resistant Enterococcus in some cases, though with varying efficacy), Staphylococcus (including MRSA), and also note that the options: Enterococcus is a gram - positive genus, Staphylococcus is gram - positive. Proteus, Enterobacter, Pseudomonas are gram - negative and Synercid is not effective against them. So the correct genera are Enterococcus and Staphylococcus. Wait, let's re - check: Synercid (quinupristin/dalfopristin) is indicated for infections caused by Enterococcus faecium (vancomycin - resistant strains, VRE), Staphylococcus aureus (including MRSA), Streptococcus pneumoniae, etc. Among the given options: Enterococcus (gram - positive), Staphylococcus (gram - positive) are the ones Synercid is effective against. Proteus, Enterobacter, Pseudomonas are gram - negative, so Synercid is not effective against them.

Answer:

A. Enterococcus, B. Staphylococcus (Wait, in the image, the options are: Enterococcus, Proteus, Enterobacter, Staphylococcus, Pseudomonas. So the correct ones are Enterococcus and Staphylococcus. So the checkboxes for Enterococcus and Staphylococcus should be selected. So the answer is:

• Enterococcus (the checkbox next to Enterococcus)
• Staphylococcus (the checkbox next to Staphylococcus)
