Atresia
is a condition in which a body orifice or passage in the body is abnormally closed or absent.
Reverse transcriptase
a polymerase that catalyzes the formation of DNA using RNA as a template
Viremia
the presence of a virus in the blood stream
Tropism
an involuntary orienting response; positive or negative reaction to a stimulus source
Syncytia
Expression of glycoproteins on the surface of infected cells triggers the fusion of neighboring cells into multinucleated giant cells
Prodrome
Incubation period may proceed without symptoms (asymptomatic) or may produce nonspecific early symptoms such as fever, head or body ache, or chills
Prions
Infectious protein particles that do not have a genome.
Peyer patches
Gut-associated lymphoid tissue present in the wall of the small intestine, especially the ileum.
Papillomas
a benign tumor (as a wart) resulting from an overgrowth of epithelial tissue on papillae of vascularized connective tissue
Oncogenic
causing tumors
lymphadenopathy
chronic abnormal enlargement of the lymph nodes (usually associated with disease)
Intussusception
growth in the surface area of a cell by the deposit of new particles between existing particles in the cell wall
integrin
A receptor protein built into the plasma membrane that interconnects the extracellular matrix and the cytoskeleton.
Cervical Carcinomas
Cervical cancer is a disease in which the cells of the cervix become abnormal and start to grow uncontrollably, forming tumors
Clathrin
Protein that plays a major role in vesicle formation during receptor mediated endocytosis; forms a coated pit on the plasma membrane
Demyelination
loss of the myelin covering of some nerve fibers resulting in their impaired function
Arboviral
diseases reflect the life cycle of the arthropod vector or its reservoir (e.g., birds)
Apoptosis
programmed cell death
Pleomorphic
the appearance of two or more distinctly different forms in the life cycle of some organisms
Hematemesis
vomiting blood
Epistaxis
bleeding from the nose
Ecchymosis
the escape of blood from ruptured blood vessels into the surrounding tissue to form a purple or black-and-blue spot on the skin
Chikungunya
virus (CHIKV) is an insect-borne virus, of the genus Alphavirus, that is transmitted to humans by virus-carrying Aedes mosquitoes. Severe and crippling arthritis
Neuraminidase
glycoprotein found on the surfaces of viruses, that catalyzes the hydrolysis of terminal acylneuraminic residues from oligosaccharides, glycoproteins, and glycolipids
Hemagglutinin
Major cell surface glycoprotein; Facilitates binding to host cell receptors and endosomal fusion
Oophoritis
inflammation of one or both ovaries
Croup
a disease of infants and young children; difficult breathing
Parotitis
inflammation of one or both parotid glands
Bronchiolitis
inflammation of the membranes lining the bronchioles
Encephalitis
inflammation of the brain usually caused by a virus
Exanthem
eruption on the skin occurring as a symptom of a disease
Photophobia
pain in the eye resulting from exposure to bright light
Conjunctivitis
inflammation of the conjunctiva of the eye
Pleurodynia (Bornholm disease)
aka devil's grip, excruciating chest and abdominal pain
Herpangina
vesicular ulcerated lesions around the soft palate and uvula
Bulbar poliomyelitis
more severe, effects pharynx, vocal chords and lungs, 75% death rate
Integrase
an enzyme used by retroviruses to splice itself to a genome
Kaposi sarcoma
A cancer that causes patches of abnormal tissue to grow under the skin, in the lining of the mouth, nose, and throat or in other organs. The patches are usually red or purple and are made of cancer cells and blood cells
Interferon
Inhibits proper processing (splicing) and translation of viral mRNA
Nucleoside Analofues
Modification of base, sugar or both
Viral Integrase Inhibitor
antiviral class
Virion Assembly and Release
Glycoprotein processing
Virion Integrity
Nonoxynol-9
