This document discusses the isolation and cultivation of viruses. It defines viruses as infectious, intracellular, obligate parasites. It describes methods for cultivating animal viruses, including using embryonated chick eggs, live animals, and tissue culture. The primary purposes of cultivating viruses are to isolate and identify viruses in clinical specimens, prepare viruses for vaccines, and do research on viral structure, multiplication cycles, genetics, and effects on host cells. Specific tissues and viruses that can be cultivated are also listed.

1.  ISOLATION AND
CULTIVATION OF VIRUSES

2. Cultivation and identification of viruses
 What are viruses?
Viruses are infectious ,intracellular,obligate,parasites
 Methods to cultivate animal viruses:-
1) Embryonated Chick egg
2)Live animals
3)Tissue culture
 The primary purposes of viral cultivation are:
1. to isolate and identify viruses in clinical specimens
2. to prepare viruses for vaccines
3. to do detailed research on viral structure,
multiplication cycles, genetics, and effects on host cells.
