Chapt 24-25 Chlamydia, Mycoplasma & Ureaplasma

Question 0

Elementary body

Answer 0

Metabolically inactive infectious form of Chlamydia

Question 1

Obligate intracellular parasite

Answer 1

Microorganism or virus unable to to live independently outside a living cell

Question 2

Reticulate body

Answer 2

Metabolically active noninfectious form of Chlamydia

Question 3

Trachoma

Answer 3

Chronic severe eye infection associated with specific serovars (A, B, Ba, & C) of Chlamydia trachomatis

Question 4

Lymphogranuloma venereum

Answer 4

Severe invasive STD associated with specific serovars (L1, L2, L2a, & L3) of Chlamydia trachomatis

Question 5

Nongonococcal urethritis (NGU)

Answer 5

Infectious condition of the urethra in males that is not caused by gonorrheal infection

Question 6

Atypical pneumonia

Answer 6

Pneumonia that differs from the typical pneumonia caused by Strep. pneumoniae, most often caused by Mycoplasma pneumoniae

Question 7

Cell wall deficient

Answer 7

Refers to gram(+)/gram(-) bacteria lacking a cell wall aka L-forms, exposure to antimicrobial agents that inhibit cell wall synthesis can lead to this condition… mycoplasma

Question 8

Zoonosis

Answer 8

Disease that human acquire from exposure to infected animals or products made from infected animals

Question 9

Chlamydia

Answer 9

Obligate intracellular parasites, unable to produce/store ATP (energy molecule), stain poorly with gram stain, requires Direct Fluorescent Stains to observe, Chlamydia trachomatis is most common bacterial STD

Question 10

Chlamydia Life Cycle

Answer 10

Elementary Body (EB)->Phagocytosis of EB by host cells->EB(->Reticulate Body->) Release of EBs from host cells

Question 11

Non-gonococcal urethritis

Answer 11

Serotypes D-K

Question 12

Trachoma

Answer 12

Serotypes A-C

Question 13

Lymphogranuloma venereum

Answer 13

Serotypes L1-L3

Question 14

Mycoplasma

Answer 14

Smallest free living organism, “cell wall deficient”, lack a rigid cell wall, pleomorphic, resistant to cell wall agents (Penicillin)

Question 15

Mycoplasma pneumoniae

Answer 15

Causative agent of “atypical pneumonia”, high titers of IgM anti-I antibody, “cold agglutination syndrome, complex nutritional requirements, difficult to culture in vitro

Question 16

Ureaplasma

Answer 16

Similar to Mycoplasma, associated with non-gonococcal urethritis & newborn pneumonia

Question 17

Rickettsia & Ehrlichia

Answer 17

Obligate intracellular parasitess, fastidious, difficult to culture in vitro, ID’d by serological tests
