The International Symposium on Frontiers in Microbiology has been de dicated to Prof. P. De Somer, whom I succeeded shortly after his death on 17 June 1985 as Rector of this now more than 560-year old University. When Prof. De Somer became the head of the University he started to remodel it, giving our old Alma Mater a more transparent administrative structure, strengthening its scientific and cultural autonomy, and establishing close links with the most prestigious national and foreign institutions. This made De Somer to one of the greatest, if not the greatest, of rectors in the history of...

HIV infection has been a greater challenge to current medicine than any other viral disease ofmodem times. HIV leads to a persistent infection and the virus has an immense genetic flexibility under selective pressure. During its replica tive cycle in patients, HIV accumulates mutations at such a high rate that the selective pressure inflicted on the immune system, or generated by antiviral drugs rapidly triggers the appearance of escape mutants. Currently available drugs, when used singly, are not capable of suppressing virus replication in patients to such a level that the generation of...

Antiviral chemotherapy has come of age, and, after an initial slow pro gress, the development of new antiviral agents has proceeded at a more rapid pace and the perspectives for their clinical use have increased considerably. Now, 25 years after the first antiviral assay (idoxuridine) was introduced in the clinic, it is fitting to commemorate the beginning of the antivirals' era. In its introductory chapter B.E. Juel-Jensen touches on what may be con sidered as five of the most fundamental requirements of an antiviral drug: efficacy, relative non-toxicity, easy solubility, ready availability...

An extensive assessment of combination therapy of AIDS. Main focus is put on the Highly Active Antiretroviral Therapy (HAART) but other therapies like salvage therapy are also discussed. The chapters cover efficacy, treatment, causes of treatment failure, clinical care, guidelines, pharmacology. The volume closes with an outlook on future perspectives.
