Modes of Virus Transmission

Virus transmission may be 'horizontal' or 'vertical'. The vast majority of transmission is horizontal, that is, between individuals within the population at risk. Modes of horizontal transmission of viruses can be characterized as direct contact, indirect contact, common vehicle, airborne, vector-borne, iatrogenic, and nosocomial. Vertical or transplacental transmission occurs between the mother and her fetus or newborn. Some viruses are transmitted in nature via several modes, others...

Panherpes PCR with Degenerate Primers

The method is based on the fact that herpesvirus genomes contain highly conserved genes, which are present in all because they code for proteins essential for viral growth. One of the most conserved is the herpesvirus DNA polymerase (DPOL) gene. Investigators aligned the DPOL genes of all herpesviruses for which sequence data were available, in order to identify short blocks of greatest amino acid identity that encode domains essential for DPOL function. This procedure allowed the design of...
