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

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
