| discovery of naturally occurring transmissible chronic hepatitis b virus infection among macaca fascicularis from mauritius island. | despite a high prevalence of hepatitis b virus (hbv) infection in endangered apes, no hbv infection has been reported in small, old-world monkeys. in search for a small, nonhuman primate model, we investigated the prevalence of hbv infection in 260 macaque (cercopithecidae) sera of various geographical origins (i.e., morocco, mauritius island, and asia). hbv-positive markers were detected in cynomolgus macaques (macaca fascicularis) from mauritius island only, and, remarkably, hbv dna was positi ... | 2013 | 23536484 |
| prevalence of antibodies against hepatitis a virus, hepatitis b virus, and treponema pallidum in mauritius. | a seroepidemiological study on the prevalence of antibodies against hepatitis a virus (hav), hepatitis b virus (hbv) and treponema pallidum was conducted in various groups of the population of the state of mauritus (islands of mauritus and rodrigues). 618 sera were tested. the overall prevalence of anti-hav was 86.1% and yielded and age-dependent increase. serological evidence for acute or chronic hbv infection was found in 3.8%; 4.5% were positive for anti-hbc alone, and in 12.6% past hbv infec ... | 1991 | 1662829 |
| the prevalence of hepatitis-b antigen (hb s ag) and its antibody (anti-hb s) among london hemophiliacs and blood donors from london and two tropical areas. | the prevalence of hepatitis-b antigen (hb s ag) and its antibody (anti-hbs) among 49 london hemophiliacs was compared with that among women attending an antenatal clinic and healthy blood donors from london and from two parts of the tropics (mauritius and zambia). the prevalence of hbsag and anti-hbs was low in antenatal patients, london blood donors and blood donors from mauritius. however, a high proportion of hemophiliacs (59%) were anti-hbs positive, this being comparable with zambian blood ... | 1976 | 936273 |
