The set of all microorganisms that’s re associated with that organism

Question 11

Resident organisms

Answer 11

Microbiota that vary from location to location on organisms and from organism to organism

Question 12

Gram negative bacteria classification

Answer 12

Proteobacteria, cytophaga-favobacterium-bacteriodes (CFB) and spirochete groups

Question 13

Gram positive bacteria classification

Answer 13

Low and high GC groups
(Guanine and cytosine)

Question 14

Phylum proteobacteria (4)

Answer 14

1) ***Alphaproteobacteria (all obligate or facultative intercellular bacteria) ; infectious and disease

2) Betaproteo (metabolic diversity) ; important meningitis, gonorreha, sicca

3) ***Gammaproteobacteria ; ecoli, vibrio colora, samonella, yersinia

4) Espilonproteobacteria ; least relevant and smallest group

Question 15

Aphaproteobacteria

Answer 15

Can survive on low nutrients

Clinically relevant ;

bartonella henselae (cat scratch fever)

brucellosis abortus & meletensis (undulating fever)

Coxiella burnetii (Q fever)

Erlichia spp. (Erlichosis)

Rickettsia spp. (Rocky Mountain spotted fever & epidemic thyphus)

Question 16

Betaproteobacteria

Answer 16

Highly metabolically diverse ( heterthrophs, chemotrophs, phototrophs)

Clinically diverse;

Bordetella pertussis (whooping cough)

Burkholderia pseudomallei (pneumonias)

Neisseria mengitis, gonorrhorea, sicca

Question 17

Gammaproteobacteria

Answer 17

Most diverse of all proteobacteria includes soil, deep sea, important human pathogens, and bioluminescence marine bacteria

Escherichia coli – contains a wide variety ranging from mutualists (normal intestinal flora) to pathogens (E. coli O157:H7)

Hemophilus influenzae – respiratory disease

Klebsiella pneumoniae – alcoholic’s pneumonia

Legionella pneumophila – Legionnaire’s disease

Proteus spp. – urinary tract infections and sepsis

Pseudomonas aeruginosa – soil bacterium that is a multidrug-resistant opportunistic pathogen; wound infections, pneumonias, sepsis

Serratia spp. – nosocomial infections

Shigella spp. – dysentery, hemorrhagic diarrhea

Vibrio cholerae, parahemolyticus, vulnificus – water-acquired diseases

Cholera, shellfish food poisoning, dangerous wound infections

Yersinia pestis – bubonic plague

Salmonella serovars – salmonellosis, typhoid fever

Question 18

Epsilonproteobacteria

Answer 18

The smallest class of proteobacteria

Clinically relevant Epsilonbacteria:

Campylobacter jejuni – food poisoning causes a severe enteritis, often with extremely high fevers

Helicobacter pylori – a usually beneficial human gut bacterium, it has been associated with chronic gastritis, ulcers, and perhaps even stomach cancer
