FACTORS THAT INCREASE THE INTENSITY (PATHOGENICITY OR VIRULENCE) OF VIRAL INFECTIONS
The ability of a pathogenic virus to cause disease in a host (i.e., viral pathogenesis or virulence) is usually affected by several factors which are […]
VIRAL TROPISM AND PATHOGENESIS
Pathogenic viruses exhibit cell/tissue tropism – in which a given virus shows affinity to specific host cells or tissues after entry. Tropism in this case,is […]
VIRAL INFECTIONS
Pathogenesis is simply defined as the mechanism of disease development in a host. The interaction of pathogenic viruses (inclusive of DNA and RNA containing viruses) […]
ANIMAL INOCULATION AND CELL/TISSUE CULTURE SYSTEMS OF VIRUS CULTIVATION
The animal models used for viral inoculation include experimental animals such as transgenic animals, monkeys, primates or non-human primates (NHPs), hamsters, guinea pig, and laboratory […]
VIRAL CULTIVATION IN THE MICROBIOLOGY LABORATORY
Viral cultivation unlike the cultivation or culture of other microbial forms including bacteria and fungi is quite unique and different from the usual routine cultivation […]
