Published	08/28/2024	Chlamydia are {{c1::obligate}} intracellular. They have 2 distinct forms:1. {{c2::Reticulate}} bodies: replicating inside host cells2. {{c2::Elementar…
Published	08/28/2024	The best time to target bacteria is during the {{c1::log/exponential}} phase of the growth curve.
Published	08/28/2024	All organisms other than {{c1::viruses}} and {{c1::prions}} are made up of at least 1 cell
Published	08/28/2024	{{c1::Bacillus/bacilli}}: rod-shaped
Published	08/28/2024	Curved: rods with one or more curves; sometimes called {{c1::vibrio}}
Published	08/28/2024	{{c1::Filamentous}}: rods that remain attached to each other. Resemble fungi

Published	08/28/2024	{{c1::Spirochete}}: spiral-shaped
Published	08/28/2024	Functions of gut microbiota include: {{c1::metabolic}}, {{c1::devensive}}, and {{c1::trophic}}
Published	08/28/2024	Escherichia coli and other coliforms are normally found in the {{c1::colon}}, {{c1::vagina}}, and {{c1::outer urethra.}}
Published	08/28/2024	Gardnerella {{c1::vaginalis}} are normally found in the vagina.
Published	08/28/2024	Lactobacillus species are normally found in the {{c1::mouth}}, {{c1::colon}}, and {{c1::vagina}}.
Published	08/28/2024	Staphylococcus aureus are normally found in the {{c1::nose}} and {{c1::skin}}.
Published	08/28/2024	Viridans streptococci are normally found in the {{c1::mouth}} and {{c1::nasopharynx}}
Published	08/28/2024	Archaea are {{c1::never}} pathogens
Published	08/28/2024	Antibiotics, poor diet/nutrition, and medical procedures could disrupt the normal {{c1::flora}}.
Published	08/28/2024	{{c2::Gram-negative}} bacterial have both and inner and outer membrane, with a think layer of {{c1::peptidoglycan}} in between.
Published	08/28/2024	Gram-{{c1::negative}} bacteria has lipopolysaccharides on the outer surface.
Published	08/28/2024	Gram-{{c1::positive}} bacteria has strands of {{c2::lipoteichoic}} acid and {{c2::teichoic}} acid within its thick peptidoglycan outer layer.
Published	08/28/2024	Gram-{{c2::negative}} bacteria outer membrane contains a {{c1::lipid A}} portion (endotoxin). It is a potent stimulator of the immune system.
Published	08/28/2024	peptidoglycan is made up of a {{c1::sugar}} backbone and {{c1::peptide}} interbridges.
Published	08/28/2024	Gram-{{c1::Positive}} – Purple – LOTS of Peptidoglycan
Published	08/28/2024	• Staphylococcus: Gram-{{c1::positive}} cocci in grape-like {{c1::clusters}} • Escherichia: Gram-{{c2::negative}} rods • Bacillus: Gram-{{c3::pos…
Published	08/28/2024	{{c1::Mycoplasma}}, Chlamydiae, Ricketsiae, and {{c1::Mycobacterium}} don't gram-stain.
Published	08/28/2024	Mycobacterium have a high {{c1::lipid}} content in their cell walls, making them resistant to {{c1::gram staining}} ("acid-fast").

Published	08/28/2024	{{c1::Aerotolerant anaerobes}}: Use fermentation to produce ATP • Do not use oxygen, but can protect themselves from reactive oxygen molecules
Published	08/28/2024	{{c1::Microaerophillic}}: requires environments containing lower levels of oxygen.
