title: Serological investigations for antibodies against Treponema pallidum on the Cape Verde Islands (Santiago and Santo Antao)--2. report.
abstract: On the Cape Verde Islands, Santiago and Santo Antao 581 human blood samples were collected. The VDRL and TPHA tests were employed in the serological examinations of samples for antibodies against Treponema pallidum. Positive reactions were shown in 2 of the 191 sera from the Santiago Island and in 12 of the 390 sera from the Santo Antao Island in both the VDRL and the TPHA tests. Including the alone TPHA-positives of 5 and 8 sera respectively, results in a 3.7% of positive sera for Santiago and a 5.1% for Santo Antao. By not taking into account children under 13 years of age, the positivity rises to 4.2% and 7.6% respectively. Giving a total contamination rate of 6.3% for Treponema pallidum.
