2. viruses

2.1. DNA viruses

2.1.1. Adenoviridiae Double stranded DNA Icosahedral viral capsid infect humans and animals organs affected attaches through capsular knobs inters through endocytosis (receptor mediated) viral replication kills the cell Clinical infections Acute upper respt. tract infection Ocular infection Gastrointestinal RARE infections

2.1.2. Herpesviridiae General features enveloped double stranded DNA LARGE DNA Capsid is icosahedral Tegument contains enzymes Infection lead to latency Viral cycle follow the enveloped DNA cycle alpha Herpes simplex 1,2 VZV beta CMV HHV-6 HHV-7 gama EBV

2.1.3. Hepadnaviridiae enveloped partly circle double stranded DNA partly the short strand is half the negative long one Icosahedra capsid DNA encode DNA capside antigen envelop antigen reverse transcriptase non-structural regulatory protein X Hepatitis B virus parenteral transmission Liver damage due to immunological reaction

2.2. RNA viruses

2.2.1. Orthomyxoviridae (flu) General features Negative strand 8 segments spherical enveloped 2 spikes proteins M protein underlay the viral lipid membrane replication occur in the nucleus 3 groups A,B,C Influenza infection through resp. droplets restricted in the resp. tract symptoms damage to resp. epithelial cells

2.2.2. Paramyxoviridae (measles and mumps) general features ss negative spherical enveloped Helical nucleocapsid Mumps respiratory infection 30% subclinical infects parotid salivary glands and enlarges it can escape to other parts of the body Measles

2.2.3. Flaviviridae

2.2.4. Retroviridea (HIV)
