Hepatitis in marmosets.

Some species of marmosets are susceptible, not only by parenteral inoculation but also by oral exposure, to human hepatitis A virus present in sera or feces. The stools of animals inoculated parenterally or orally contained fecal antigen during certain times of the incubation period and the early, acute phase of the disease; viruslike particles were present in feces of orally infected animals and such feces were infectious when inoculated into marmosets. The fecal antigen crossreacted both with the fecal virus particles and the immune-adherence antigen (see also papers by Purcell et al and Hilleman et al). The MS-1 and CR-326 strains of hepatitis A appeared antigenically similar or identical whereas the GB strain was antigenically different and may be associated with the recently defined type of hepatitis termed hepatitis C or hepatitis non-A/non-B. On repeated challenge hyperegic responses with diffuse liver cell necrosis occurred in some immune animals and this phenomenon must be taken into account in any future vaccination studies.

University students' knowledge of STDs: labels, symptoms and transmission.

A sample of 630 Victorian university students, aged between 17 and 24, completed a questionnaire on knowledge of sexually transmitted diseases (STDs). Overall students demonstrated moderate levels of knowledge about the names of diseases which are transmitted by sexual contact, symptoms and medical facts and transmission modes of common STDs. However, they had more knowledge about the labels than they did about symptoms and transmission modes and were misinformed about certain clinical aspects of STDs. It was found that the different levels of knowledge varied with the type of STD. Knowledge about symptoms of transmission did not correlate with a disease's incidence or clinical aspects. Sexual experience and having an Australian born mother correlated with higher scores. This study suggests that young people do not have high levels of knowledge about common STDs they may encounter. Identification of a label is of limited personal value if there is no concurrent knowledge about disease transmission and prognosis.
