Low G + C Gram Positive Bacteria
Form endospores (spherical or oval)
Strictly anaerobic rods found in soil, water, intestinal tract of humans & other animals.
Also in Sewage , marine sediments, and decaying vegetation.
Bacteria lacking cell walls and cannot synthesized peptidoglycan precursor.
Gram negative by default.
Genus Mycoplasma, Ueraplasma, and Spiroplasma.
Produces a human disease called atypical pneumonia or walking pneumonia.
Most freguently affects person 5-25 years old.
Causal agent in 25% of all pneumonias in young adults.
hydrolyzes urea and requires a 10% urea medium to grow.
Approx 1-2.5 million ppl in the U.S. are infected and can result in NGU.
The organism tightly to sperm and can be transmitted by them to sexual pertners.
Can be cultured from urethral and vaginal discharges.
Estimated that it accounts for more than half of all infections that make couples infertile.
causes citrus stubborn disease.
Transmitted by leafhopper.
Cells rod shaped, straight, or nearly so.
Form endospores with only one per cell.
Sporulation not repressed by exposure to air.
Gram positive or positive in the early stages of growth.
Motility by peritrichous flagella or nonmotile.
Aerobic or facultatively anaerobic.
Most species are saprophytes in soil, water, and vegetation.
Motile by peritrichous flagella
Aerobic or facultative anaerobic.
usually form irregular clusters.
Natural populations mainly assoicated with skin, skin glands, and mucous membranes of warm blooded animals including humans.
Species are opportunistic pathogens of humans and/ or animals.
Long rods to short rods.
Large amounts of lactic acid formed.
Important in production of yogurt and sauerkraut
Also parasites in the mouth, intestinal tract and vagina of humans and warm blooded animals.
Pathogenicity is rare.
Cocci arranged in pairs or chains.
Heterofermintative- form CO2 and ethanol or acetic acid in addition D - lactic acid
Nonpathogenic to plants and animals.
Important in production of sauerkraut.
Cell arrangeed in pairs or chains.
Most species are facultative anaerobes.
Homofermentative- production of one primary product as a result of fermentation.
With the production of L + lactic acid.
Commensals or parasites on humans or animals
Some are highly pathogenic.
