What organism produces Hemagglutinin, influenza virus (ha)?
What is the action of hamagglutinin?
What is the purpose of hamagglutinin?
- binds lipids to epithelial cells
- binds glycoproteins to neutophils
- allows membrane fusion y enveloped viruses
- facilitates attachment to cells
- causes neutorophiles to phagocytize the pathogen and allow the pathogen to live within neutrophils.
What organism produces neuraminidase (sialidase)?
What is the action of neuraminidase?
What is the purpose?
Pseudomonas aeruginosa and the influenza virus, Bordetella pertussis.
cleaves neuramic (sialic) acids.
enhances attachment to cell receptors
What organisms produce proteins a and g?
What is the location of the proteins and their organisms?
What is the cation of these proteins?
What is their purpose?
- protein a: Staphylococcus aureus
- protein g: Streptococcus pyogenes
binds to the Fc protion of anitbodies.
interferes with pahocytoces and enhances attachment to host cells while making pathogen resistant to heat and acidic environments.
What is m protein?
What organism produces that protein?
What is the action of m protein?
What is the purpose of matrix protein?
- adherance to keratinocytes
- prevents opsoniztion by complement
What organisms produce porins?
What are porins?
- salmonella enterica and neisseria
- tirmetric proteins that span the plasma membrane and facilitate the transport of molecules.
What two organisms produce mycolic acid?
What is the action of Mycolic acid?
- inhibits phagocytosis
- protects against cheimcal inhibitors of growth.
What two organisms produce h2o2 and ammonia?
Are they waste products of metabolic activity within the pathogen?
What is the action of h2o2 and ammonia?
mycoplasma and ureaplasma
damages epithelial cells in the respiratory tract and the urogenital tract
