INTRODUCTION
PROPERTIES
NOT CELLULAR, CONTAIN COMPACT AND ECONOMICAL STRUCTURE
-
-
-
OBLIGATE INTRACELLULAR PARASITES OF ANIMAL, PLANT, BACTERIA, FUNGI, PROTOZOA AND ALGAE
-
BASIS STRUCTURE OF VIRUS USUALLY CONSISTS OF ENVELOPE OR CAPSID OR PROTEIN SHELL WRAPPED AROUND THE NUCLEIC ACID CORE
-
-
-
-
VIRUS MULTIPLY BY TAKING OVER THE HOST CELL GENETIC MATERIAL AND REGULATING SYNTHESIS AND ASSEMBLY THE NEW VIRUSES INSIDE THE HOST CELL
CHARACTERISTICS
-
-
-
WHEN VIRUS INVADE THE SUSCEPTIBLE HOST, THEY DISPLAY SOME PROPERTIES OF LIVING ORGANISMS AND APPEAR TO E BORDERLINE BETWEEN LIVING AND NON LIVING
-
VIRUSES DO NOT UNDERGO DIVISION, THEY UNDERGO REPLICATION
-
VIRUSES CANNOT REPRODUCE ON THEIR OWN, INSTEAD THEY NEED HOST TO MULTIPLY
VIRUSES ARE NOT MADE OF CELL, THEY ARE PARTICLE OR ACELLULAR PARTICLE
COMPONENTS
-
ENVELOPE
ENVELOPE COMPOSED OF PROTEIN, LIPID BILAYER AND CARBOHYDRATE
-
-
ENVELOPED VIRUS HAVE A TYPICAL BILAYER MEMBRANE OUTSIDE THEIR CAPSID AND TEH VIRIONS IN THE CELL ACQUIRE THEIR ENVELOPE AFTER THEY ASSEMBLED IN THE HOST CELL AND "BUD" THROUGH HOST MEMBRANE
-
-
SPIKE
-
SPIKE ARE THE GLYCOPROTEIN, AID IN ATTACHMENT TO THE HOST CELL
-
-
GLYCOPROTEIN
GLYCOPROTEIN IS TEH SURFACE PROJECTION THAT SERVE TO ATTACH VIRIONS TO A SPECIFIC RECEPTOR SITES ON THE SUSCEPTIBLE HOST CELL SURFACE
-
BACTERIOPHAGE
-
PHAGES ARE UTILIZED IN TYPING OF BACTERIA, IN DIAGNOSTIC SYSTEMS AND AS POLLUTION INDICATOR
-
INTEREST IN THERAPEUTIC POTENTIAL OF PHAGES, DUE LARGELY TO RAPID EMERGENCE OF ANTIBIOTIC-RESISTANT BACTERIA AND A NEW INFECTIOUS DISEASE
T-EVEN PHAGE (T2, T4, AND T6): "T" STANDS FOR TYPE, USED TO UNDERSTAND THE PHAGE REPLICATION
-
PHASE
EXTRACELLULAR
PROCESS FEW ENZYMES, DO NOT REPRODUCE
-
INTRACELLULAR
-
EXIST MAINLY AS REPLICATING NUCLEIC ACID THAT CONTROL THE HOST CELL METABOLISM IN THE SYNTHESIS OF NEW VIRUSES
