Neisseria species- habitat Exist as normal flora of the mucous
membranes in
the upper respiratory and urogenital tracts
Neisseria species- primary N. Gonorrhoeae and meningitides
pathogens
___ is NOT considered normal Neisseria gonorrhoeae
biota
and is ALWAYS pathogenic
Neisseria species- general Aerobic, capnophilic, gram-negative
characteristics diplococci
Optimal growth in humid atmosphere
Oxidase and catalase-positive
Non-motile
Non spore forming
Neisseria species- virulence Capsule
factors Pili (Fimbriae)
Lipoligosaccharide (LOS) or endotoxin
Immunoglobulin A (IgA) protease
Receptors for human transferrin
Capsule
,Major outer protein porin proteins Protein I (Por A/B)
Protein II (Opa)
Protein III
Protein I Effective against inflammatory response
and
complement killing
Protein II (Opa) Facilitate adherence to phagocytic and
epithelial
cells
Protein III Block host serum bactericidal action (IgG)
Lipoligosaccharides (LOS) Mediates tissue damage
endotoxin Elicits inflammatory response
Lipid A moiety and core LOS that
differentiates it
from the lipopolysaccharide (LPS)
Humans are the only natural host Neisseria gonorrhoeae
Means "flow of seed" (purulence Gonorrhea
mistaken for semen)
Most commonly transmitted by Gonorrhea
sexual contact
- reportable disease
, Neisseria gonnorrrhoeae: clinical Acute pyogenic infection of the
manifestations - urethra
- endocervix
- anal canal
- pharynx
- conjunctiva of the eye
Gonorrhea in the male 95% infected show no symptoms of acute
infection
(urethritis)
Symptoms include:
- dysuria (painful urination)
- purulent urethral discharge (most
common
manifestations)
Complications:
- epididymitis
- urethral stricture
- prostatitis
Gonorrhea in the female 50% asymptomatic
Endocervix is most common site of
infection
Symptoms:
- dysuria
- cervical discharge
- lower abdominal pain
Complications:
- pelvic inflammatory disease (PID)
- sterility
- ectopic pregnancy
- perihepatitis (Fitz-Hugh-Curtis-syndrome)
