The CDC added that most cases have been reported among gay, bisexual, and other men who have sex with men in Illinois, Minnesota, and Montana and among international travelers, but cases are also occurring among other populations.Īmpicillin and TMP-SMZ are effective for susceptible strains amoxicillin is less effective than this because of its rapid absorption high in the GI tract. In June 2015, the Centers for Disease Control and Prevention (CDC) warned that they received reports of infections with Shigella strains that are not susceptible to ciprofloxacin and/or azithromycin. ![]() Recently, Shigella isolates with decreased susceptibility to azithromycin (DSA- Shigella), with minimum inhibitory concentration (MIC) greater than 16 µ g/mL has been described by the CDC. Oral first- and second-generation cephalosporins are inadequate despite in vitro susceptibility. Amoxicillin is less effective than ampicillin for treatment of ampicillin-sensitive strains. ![]() If an ampicillin and TMP-SMX resistant strain is isolated or if susceptibility is unknown, parenteral ceftriaxone sodium, fluoroquinolone (eg, ciprofloxacin, ofloxacin), azithromycin dihydrate (off-label indication), or oral cefixime are the drugs of choice.
