BEFORE
NEUROTROPHIC, VIRUS THAT INFECT NERVE CELL
VISCEROTROPIC, VIRUS THAT INFECT ORGAN AND DIGESTIVE TRACT
-
PNEUMOTROPIC, VIRUS THAT INFECT RESPIRATORY SYSTEM
-
REASON
CAN BE APPLY TO ALL ANIMAL VIRUSES, PLANT VIRUSES AND BACTERIAL VIRUSES
-
-
-
TAXONOMIC GROUP

BALTIMORE
ADVANTAGES
THIS METHOD HELP CLASSIFY BETWEEN THE (+) STRAND RNA VIRUSES THAT DO (CLASS VI) AND DO NOT (CLASS IV) UNDERGO REVERSE TRANSCRIPTION
THIS METHOD CAN ALSO CLASSIFY BETWEEN THE DSDNA VIRUSES THAT DO (CLASS VII) AND DO NOT (CLASS I) UNDERGO REVERSE TRANSCRIPTION
VIRUS
RNA VIRUS
GENERAL PROPERTIES
OTHER SSRNA VIRUSES HAVE (-) SENSE RNA AND THE RNA ACTS AS TEMPLATE DURING TRANSCRIPTION TO MAKE A COMPLEMENTARY (+) SENSE MRNA
-
-
RNA VIRUSES MUST EITHER CARRY ENZYMES OR HAVE GENES FOR THOSE ENZYMES IN ORDER TO COPY RNA GENOMES AFTER INFECTING A HOST CELL
-
-
DNA VIRUS
GENERAL PROPERTIES
-
DSDNA VIRUSES ARE FURTHER SEPARATED INTO FAMILIES ON THE BASIS OF THEIR DNA SHAPE, CAPSID SHAPE AND THE PRESENCE OR ABSENCE OF ENVELOPE
JUST LIKE RNA VIRUSES, THE ANIMAL DNA VIRUSES ARE GROUPED INTO FAMILIES ACCORDING TO THEIR DNA ORGANIZATION
AMBISENSE GENOME IS A VIRUS GENOME COMPOSED OF SSDNA OR SSRNA THAT IS PARTLY (+) SENSE AND PARTLY (-) SENSE
-
-

-
DEFINITION
THE DIVISION OF VIRUSES INTO CLASSES BASED ON GENOME, MODE OF REPLICATION AND TRANSCRIPTION
