Week 20 Posted on May 28, 2023 by Riya Ghandi Please answer the following questions: Step 1 of 2 50% Please check which of the statement(s) are Recommendations by the Interim Guideline for the Detection and Identification of Group B Streptococcus (2020)(Required) Nucleic acid amplification-based identification of GBS from enrichment broth is acceptable, but not sufficient for all patients. Report GBS in any quantity from urine cultures from pregnant women during all trimesters. Collect vaginal-rectal specimens using a flocked swab and place in a liquid-based transport medium such as Amies transport media. Culture media and GBS isolation methods should detect both hemolytic and nonhemolytic strains. Use a single swab to obtain a screening specimen first from the lower vagina and then from the rectum without use of a speculum. Perform antimicrobial susceptibility testing on all GBS isolates from pregnant women with severe penicillin allergy. Acceptable phenotypic and proteomic methods of identification of candidate isolates include CAMP test, latex agglutination, and (MALDI-TOF). Incubate GBS screening specimens in selective enrichment broth prior to agar media plating or NAAT. Latex agglutination directly from enrichment broth and direct-from-specimen immunoassays are unacceptable methods for GBS detection. Please select the correct statement(s)(Required) In pregnant women with positive group B streptococcus screening, both clindamycin and erythromycin susceptibility results should be reported. Group B streptococcus colonization isolates from pregnant women with severe penicillin allergy (high risk for anaphylaxis) should be tested for inducible clindamycin resistance. Universal screening at 36-37 weeks' gestation for maternal GBS colonization and use of intrapartum antibiotic prophylaxis has resulted in substantial reductions in early-onset GBS disease among newborns.
