| observations on syphilis in addis ababa. 2. prevalence and natural history. | sera from various groups were tested for syphilis by cardiolipin, fluorescent treponemal antibody-absorbed (fta-abs), and treponemal haemagglutination (tpha) tests. the proportion of positive results, 12.7%, obtained from an unselected urban population suggested that the prevalence of the disease had declined since 1953. the probable explanation is the widespread use of penicillin. late manifestations of syphilis are much rarer in ethiopia than would be predicted from the high incidence at the i ... | 1977 | 589422 |

| decline in prevalence of hiv-1 infection and syphilis among young women attending antenatal care clinics in addis ababa, ethiopia: results from sentinel surveillance, 1995-2001. | from 1995 to 2001, five rounds of sentinel surveillance were carried out for young women attending antenatal care clinics at four health centers in addis ababa, the capital city of ethiopia, to monitor trends in the prevalence of hiv infection and syphilis. serum samples were tested for antibodies to hiv (enzyme-linked immunosorbent assay and western blotting) and antibodies to treponema pallidum (t. pallidum hemagglutination assay and rapid plasma reagin test). prevalence ratios for an increase ... | 2002 | 12131574 |
| lipoidal antigen and tpi reactions in sera from ethiopia. effect of long-distance serum transportation on antibodies. | in order to evaluate results obtained in addis ababa with lipoidal antigen tests for syphilis on 269 human sera, and, if possible, to determine how many positive seroreactors were in fact infected with treponema pallidum, these sera were sent by air to copenhagen for re-examination by the vdrl, kahn, cwrm and tpi tests.approximately 60% of sera reactive in vdrl tests in ethiopia were also vdrl-reactive in copenhagen, and some 75% were tpi-reactive. as the same vdrl techniques were used in the tw ... | 1964 | 14163960 |
