Lamivudine, telbivudine and adefovir resistance Older antiviral agents, lamivudine, telbivudine and adefovir which are no longer recommended for use in Australia, are sometimes used by people arriving from countries overseas. HBV genotype appears to play no role in the development of resistance or response to therapy.

Alternative antiviral therapy — interferon The development of longer-acting pegylated forms of interferon IFN has stimulated renewed interest in treating patients with immunomodulatory agents. New antiviral drug targets Recent advances in understanding HBV replication have identified a number of potential antiviral drug targets.

Conclusion Resistance has not been a critical issue in the management of patients with CHB in Australia because long-term therapy with the first-line NAs tenofovir disoproxil and entecavir have a high genetic barrier and good safety profile.

This would involve finding or creating a viral agent that could not only be controlled, but could be used to create new bio-weapons by infecting a host organism and mutating it into a powerful creature that could act as a soldier and follow orders, as well as spread the virus that created it into enemy territory.

On December 4, , the three men succeeded, with the discovery of the Progenitor virus and from this came the birth of the Umbrella Corporation. The Progenitor virus , also known as the Founder or Mother virus, is the first of the mutagenic viruses, and the basis for all of the ones that followed.

According to the series timeline, it was discovered on December 4, , by Dr. Edward Ashford, Dr. James Marcus, and Lord Ozwell E. Though Ashford wanted to use the virus' regenerative abilities to help the handicapped, Marcus and Spencer wanted to use it for the bio-weapons project, and after Ashford's death in , they were able to begin their desired research.

The only known survivor of an experiment involving Progenitor is Lisa Trevor, who bonded with the virus in a way that baffled everyone involved with the project.

It produces rapid and uncontrollable mutation in a host's genetic code, but the mutations were not coordinated enough to produce effective B.

In hosts with a genetic structure less complex than humans, mutations are less pronounced, and usually restricted to increases in size and aggression. In order to enhance the virus's mutagenic properties, Umbrella created a variant of it through synthesizing it with the Ebola virus, but this strain retained Ebola's photosensitivity.

The Tyrant virus , or t-virus , is the main virus used by Umbrella, and is responsible for the creation of most of their B. According to reports in the game, Dr. Through this synthesis, the photosensitivity of the early Progenitor strain was replaced with pyrosensitivity, a property that can be seen in most of the series' enemies. The Tyrant virus allegedly operates similarly to most other viruses, but also has the abilities to animate dead tissue, to substantially mutate its host, and to infect nearly any tissue in any type of host.

It animates dead tissue by killing and replacing any mitochondria in infected cells, and then combining with these cells to produce enough energy for motor and lower brain functions. By doing this, most of the body's systems, such as the circulatory or respiratory systems, are made redundant. However, this process has the drawback of severe necrosis in the host, and produces the distinctive rotted appearance of most B.

The mutations are produced when the virus incorporates itself into the host's genetic code and considerably alters it.

Creatures with genetic structures different than humans generally show less severe mutations, and usually only increase in size. As a side effect of the virus' consumption of its host, specifically its digestion of the host's frontal lobes, all hosts suffer from greatly increased aggression. The virus also damages the hypothalamus , which results in a flood of neurotransmitters, enzymes, and hormones which induce a psychopathic rage and hunger in the host.

The Daylight is the only t-virus vaccine , but must be taken before transformation. The non-canon Live-action film series also present a preventative vaccine known simply as the Anti-virus , which must be taken within several hours after the initial infection.

Most people recover in a week or two, but RSV can be serious, especially for infants and older adults. RSV is the most common cause of bronchiolitis inflammation of the small airways in the lung and pneumonia infection of the lungs in children younger than 1 year of age in the United States.
