a. Charcoal-treated cotton or rayon
b. Antibiotic-treated calcium alginate
c. Non flexible Shaft of wood and not flexi-ble
d. Dacron-tipped swabs
A
A urogenital swab expressly designed for the collection of such specimens should be used. These swabs are made of cotton or rayon that has been treated with charcoal to adsorb material toxic to gonococci and wrapped tightly over one end of a thin wire shaft. Cotton- or rayon-tipped swabs on a thin wire may also be used to collect specimens for isolation of mycoplasmas and Chlamy-diae. Calcium alginate swabs are generally more toxic for herpes simplex virus (HSV), gonococci, Chlamydiae, and mycoplasmas than are treated cotton swabs. Because Dacron swabs are least toxic, they are recommended for viral specimens. Dacron-tipped swabs on plastic shafts are also acceptable for collecting specimens of Chlamydiae and genital mycoplasmas.
