Lecture 3 Flashcards
Corynobacterium
is a genus of Gram-positive bacteria - Mostly in Skin microbiota - in moist sites
Pseudomonodota
is a major phylum of Gram-negative bacteria. - Their old name is proteobacteria- They are second major group on the skin after corynobacterium - Mostly on dry sites
clostridium perfringes
is a Gram-positive, bacillus (rod-shaped), anaerobic, spore-forming pathogenic bacterium of the genus Clostridium - can be part of normal flora in some individuals.
Streptococcus
Streptococcus is a genus of gram-positive coccus (plural cocci) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales. - they tend to form pairs or chains that may appear bent or twisted. - many streptococcal species are not pathogenic, and form part of the commensal human microbiota of the mouth, skin, intestine, and upper respiratory tract.
Staphylococcus
Staphylococcus is a genus of Gram-positive bacteria in the family Staphylococcaceae from the order Bacillales. Under the microscope, they appear spherical (cocci), and form in grape-like clusters - Many species cannot cause disease and reside normally on the skin and mucous membranes of humans and other animals - in some individuals, They are residing in nose microbiota and are part of its normal flora
Cutibacterium
Cutibacterium (formerly known as Propionibacterium) species are nonsporulating, gram-positive anaerobic bacilli that are considered commensal bacteria on the skin. Genus
Propinobacterum acnes
Cutibacterium acnes (formerly Propionibacterium acnes)[1][2][3][4] is the relatively slow-growing, typically aerotolerant anaerobic, gram-positive bacterium (rod) linked to the skin condition of acne - If C.acnes and S.aurose be together on the skin they can form biofilm(acne)
Staphylococcus epidermis
s a Gram-positive bacterium, and one of over 40 species belonging to the genus Staphylococcus.[1] It is part of the normal human microbiota, typically the skin microbiota - by producing ESP S.epidermis inhibit biofilm production by S.aureuse and C.acnes.
Staphylococcus hominis
Staphylococcus hominis is a coagulase-negative member of the bacterial genus Staphylococcus, consisting of Gram-positive, spherical cells in clusters. located on the skin - They produce lantibiotic which inhibit aureuse
Staphylococcus lugdunenesis
Located on the skin- produce lugdunin which inhibit aureuse
Conjunctiva microbiota
Staphylococci - Diphteroid - Poropionibacteria - Streptococci
Diphteroid
This term is used to represent corynobacteria that are nonpathogenic
Oral microbiota
Streptococcus - Viellonela - Neisseria - Fusobacterium - Porphyromonas - Rothia - Haemophilus - Prevotella
Prevotella
Prevotella is a genus of Gram-negative bacteria.
Prevotella spp. are members of the oral, vaginal, and gut microbiota and are often recovered from anaerobic infections of the respiratory tract. -
Haemophilus
Haemophilus is a genus of Gram-negative, pleomorphic, coccobacilli bacteria belonging to the family Pasteurellaceae. These organisms inhabit the mucous membranes of the upper respiratory tract, mouth, vagina, and intestinal tract.
Rothia
Rothia is a Gram-positive, aerobic, rod-shaped and non-motile bacterial genus from the family Micrococcaceae. Rothia is prevalent in human saliva and it produces enterobactin.
Porphyromonas
Porphyromonas is a Gram-negative, non-spore-forming, obligately anaerobic and non-motile genus from the family Porphyromonadaceae. located in oral cavity
Fusobacterium
Fusobacterium is a genus of obligate anaerobic, Gram-negative,[2] non-sporeforming bacteria[3] belonging to Gracilicutes. located in oral cavity
Neisseria
Neisseria is a large genus of bacteria that colonize the mucosal surfaces of many animals. located in oral cavity. Neisseria species are Gram-negative bacteria included among the Pseudomonadota, a large group of Gram-negative forms.
Veillonella
Veillonella are Gram-negative bacteria (Gram stain pink) anaerobic cocci, unlike most Bacillota, which are Gram-positive bacteria.[1] This bacterium is well known for its lactate fermenting abilities. It is a normal bacterium in the intestines and oral mucosa of mammals
Porphyromonas gingivalis
Porphyromonas gingivalis belongs to the phylum Bacteroidota and is a nonmotile, Gram-negative, rod-shaped, anaerobic, pathogenic bacterium. It is found in the oral cavity. as well as in the upper gastrointestinal tract, the respiratory tract and the colon. It has been isolated from women with bacterial vaginosis. It can cause esophageal cancer as well as pancreatic cancer. They can be the cause of atherosclerosis.
Aggregatibacter actinomycetemcomitans
Cause panceratic cancer
Fusobacteria
Cause colorectal cancer by means of immune responses that produce oncogenes
Streptococcus mutans
Streptococcus mutans is a facultatively anaerobic, gram-positive coccus (round bacterium) commonly found in the human oral cavity and is a significant contributor to tooth decay. can be the cause of atherosclerosis.
Seudomonase auroginosa
Pseudomonas aeruginosa is a common encapsulated, Gram-negative, aerobic–facultatively anaerobic, rod-shaped bacterium that can cause disease in plants and animals, including humans. it is not part of oral flora but can cause pneumonia if it enters into airway.
Moraxella
Moraxella is a genus of gram-negative bacteria in the family Moraxellaceae. can be found in nasal and nasopharynx cavity.
Dolosigranulum
Dolosigranulum is a Gram-positive, non-spore-forming, facultatively anaerobic and non-motile bacterial genus from the family of Carnobacteriaceae. can be found in nosopharynx
Leptotichia
Leptotrichia is a gram-negative anaerobic bacillus and is a very commonly observed genus in the human oral cavity. can be seen in nosopharynx.
Tropheryma whipplei
can be found in the lungs.
Nasal cavity
Staphylococcus spp - propinobacterium spp - corynobacterium spp - Moraxella spp - Streptococcus spp
