A newborn presented with a skin “wound” (lesion) that grew predominantly beta hemolytic colonies of 5% sheep blood agar. The gram stain revealed gram positive cocci. The newborn was covered with tiny “blister like” eruptions that resembled a burn. The isolate was catalase positive. Which tests might the MLS conduct to confirm their suspicion?

A suspect spore-forming, gram-positive Bacillus species that is γ-hemolytic, nonmotile, and penicillin-susceptible and that produces a wide zone of lecithinase on egg yolk agar can be identified as:

A Group B streptococci screening test was processed by placing the genital swab in LIM broth for enrichment, followed by a nucleic acid based test.
