 virology | the study of viruses. |
| virus | can infect almost any cell. |
| viron | complete virus particle. Consists of one or more molecules of DNA or RNA, but not both. |
| virus | simple, acellular organization and pattern of reproduction. |
| capsid | viruses are enclosed in a coat of protein called: |
| virus | unable to reproduce independent of cells and carry out cell division as prokaryotes and eukaryotes do. |
| virus | range in size from 10 to 300 or 400 nm in diameter |
| virons | all, even if they posses other constituents, are constructed around a nucleocapsid core. |
| virus | can cause the formation of an inclusion body within the cytoplasm and/or nucleus of the cell it infects. |
| inclusion body | collanies of viruses. |
| replication | process of making a copy of a DNA molecule |
| virus | reproduce through replication |
| virus | strict intercellular parasites |
| virus | smallest form of life known |
| virus | known to cause hyperplasia of host cells |
| hyperplasia | an increase in size and number of a cell |
| direct contact | process by which viruses generally spread from host to host |
| fomite | inanimate object that can become contaminated |
| virual infection | produces a long last immunity |
| elective localization/tissue affinity site | viral infections in humans can be classified according to: |
| dermotropic | skin |
| pneumontropic | lungs |
| neurotropic | nerves |
| viscerotropic | organ |
| immuno-ropic | immune |
| dermotropic | Ex: Variola, varicella/varicella zoster, rubeola, rubella, herpes simplex I, herpes simplex II. |
| variola | small pox. transmitted by droplet spray, enters respiratory tract, placental transfer possible. vaccination available. (dermotropic) |
| cowpox | variola vaccination. |
| varicella | chicken pox. direct contact with droplet spray. enters respiratory tract, mild in children. (dermotropic) |
| varicella zoster/herpes zoster | shingles. reactivation of the chicken pox. Severe in adults. (dermotropic) |
| rubeola | meales. transmitted by direct contact with droplet spray. enters the respiratory tract. (dermotropic) |
| koplik spots | produced by rubeola virus |
| rubella | german measles. 3 day measles. transmitted by direct contact with droplet spray. enters the respiratory tract. enlarges the liver and spleen. (dermotropic) |
| herpes simplex I | cold sores/fever blisters appear on the weather line of lips and nostrils. transmitted by direct contact with droplet spray (oral and respiratory secretions). enters the respiratory tract. (dermotropic) |
| herpes simplex II | genital herpes (herpes progenitalis). transmitted by direct contact with lesion exudates (pus). enters the genital urinary tract. linked to cervical cancer. (dermotropic) |
| pneumotropic | Ex: influenza, cold virus, hantavirus |
| influenza virus | transmitted by direct contact with droplet spray OR indirect contact with fomites. enters the respiratory tract. opportunistic to bronchopneumonia. vaccine provides one year immunity (pneumotropic) |
| type a | hong kong flu |
| type b | swine flu |
| cold virus | rhinovirus, corzya |
| cold virus | common cold. transmitted by direct contact with droplet spray, enters the respiratory tract. no immunity. (pneumotropic) |
| rhinovirus | most commonly occuring aliment in human beings |
| hantavirus | hantavirus pulmonary syndrome |
| hantavirus | transmitted by contact with contaminated dust from the nests or droppings of rodents. enters the respiratory OR digestive tract. (pneumotropic) |
| neurotropic | Ex: rabies, viral encephalitis, poliomyelitis |
| rabies | hydrophobia. transmitted by animal vectors, deep puncture wound, rarely aerosol infections. enters the skin. non-communicable disease. affects the CNS-causes possible paralysis. Fatal if left untreated. (neurotropic) |
| viral encephalitis | ARBO virus (arthropod borne). effects the brain. transmitted by deep puncture wounds, mostly by mosquito's, ticks, and flies. affects only man and horses. non-communicable. (neurotropic) |
| encephalomyelitis | arthropod borne disease affecting the brain and spinal column. |
| poliomyelitis | paralytic polio (infantine paralysis) transmitted by direct contact with droplet spray, fecal/oral route. enters the respiratory tract or gastrointestinal tract. (neurotropic) |
| poliomyelitis | 3 forms: subclinical (95% go unnoticed), non=paralytic, paralytic |
| viscerotropic | Ex: hepatitis A, hepatitis B, hepatitis C, infectious mononucleosis, cytomegalovirus, epidemic parotitis virus |
| hepatitis type A virus | infectious hepatitis. transmitted by direct contact with contaminated feces, enters through any normal portal of entry. Symptoms: enlarged liver, jaundice condition of tissues, fever, nausea.(viscerotropic) |
| hepatitis type B virus | serum hepatitis. transmitted by direct contact with contaminated blood. enters through skin-deep puncture wound. endemic in intraveous drug use. (viscerotropic) |
| hepatitis type C virus | non A/ non-B hepatitis. transmitted though contaminated blood. enters though skin-deep puncture wound. (viscerotropic) |
| infectious mononucleosis | "kissing disease". transmitted by direct contact with droplet spray/saliva. rarely through a blood transfusion. enters the GI/ respiratory tract. (viscerotropic) |
| cytomegalovirus "CMV" | disease of glands, salivary and/or liver. transmitted by direct contact with saliva, urine, blood or bile. enters through respiratory/GI/GU tract. (viscerotropic) |
| epidemic parotitis virus | mumps. transmitted by direct contact with droplet spray. enters the respiratory tract. |
| immunotropic | Ex: HIV Virus, AIDS |
| HIV virus | AIDS. transmitted by direct contact with various bodily fluids. causes a reduction in immune defense. (immunotropic) |
