what is rickettsia?
gram negative. rod shaped bacteria. transmitted to humans by insect and tick bites. enter host cell by phagocytosis.
what is ehrlichia?
gram negative. live obligately in white blood cells. transmitted by ticks and causes ehrlichiosis, which can be fatal.
what is high G+C?
gram positive bacteria with a high proportion of guanine and cytosine nucleotides in their chromosomal DNA.
what is low G+C?
relatively low ( less than 50%) cytosine and guanine bases
what is fusiform?
tapering at both ends. spindle shaped.
what are mycoplasmas?
a group of small parasitic bacteria that lack cell walls and sometimes cause disease.
what are obligate intracellular parasites?
their reproduction is entirely reliant on intracellular resources.
what are serovars?
a distinct variation within a species of bacteria or virus or among immune cells.
what is an alpha hemolytic?
when alpha hemolysis is pr4esent, the agar under the colony is dark and greenish.
-displayed by S. pnemonidae and S. mutans
-partial or incomplete hemolysis
what is beta hemolysis?
complete lysis of red blood cells
-media is lightened yellow or transparent
-S. pyogenes and S. aureus
What is a gamma hemolytic?
what is pleomorphic?
existence of irregular and variant forms in the same species or strain of microbes
