clostridium
|
obligate anaerobes, endospore forming rods, produce toxins
Human D:tetanus, botulism, diarrhea, gangrene. Very large & lives inside a fish. Daughter cell not through bianary fussion gives birth to daughter cells |
|
bacillus
|
endospore forming rods, common in soil, many produce antibiotics, human D & animal D: anthrax, food poisoning. Pathogen of insects and catipillars
|
|
staphylococcus
|
cocci in clusters, tolerate high osmotic pressure (salty locations)& low moisture (up your nose). can survive on human skin & nose. Human D:food poisoning ...(rapid onset, got sneezed onto your food), toxic shock syndrome..skin infection. Can swap genes creating antibiotic resistance MRSA.
|
|
lactobacillus
|
on human mucosa: GI, vagina, oral cavity. perform lactic acid fermt. of carbohy. used for sauerkraut, pickles, buttermilk, yogurt
|
|
streptococcus
|
cocci in chains, produce tissue & cell digesting toxins & enzymes, evade phagocytosis, by forming a caspsule around themself. Cause many human D: scarlet fever, pharyngitis, erysipelas, impetigo, rheumatic fever, neonatal sepsis, pneumonia, dental caries. lots of human infections
|
|
enterococcus
broke streptococcus down |
on human mucosa: GI, vagina, oral cavity leading cause of (hospital infections) nosocomial infections: surgical wounds, UTI antibiotic resistant

|
|
mycobacterium
|
usually bacilli, occasionally filamentous, cell wall has mycolic acid (waxy)=acid fast, drug & dehydration resistance hard to get drugs thru waxy cell wall, they are slow growers, human D:leprosy & tuberculosis

|
|
gardnerella
|
gram variable, pleomorphic human D: vaginitis
|
|
streptomyces
|
common in soil filamentous, arerobes produce external asexual spores degrade and fly away. Recycle tough organics produce many antibiotics. Earthy smell in soil
|
|
actinomyces
|
filamentous, falcultative anaerobes in human oral mucosa human D:actinomycosis, tissue degrading disease of head, neck & lungs, starts in mouth
|
|
nocardia
|
filamentous, reproduce by fragmetation, acid fast, aerobes, in soil, human D:pulmonary infections, mycetoma. thick skin on hands and feet, 3rd world, no shoes, warm soil.
