Study Notes
Gonococcal Infections
- Gonococcal infections affect the endocervix first, leading to cervicitis and urethritis with mucopurulent discharge.
- Complications of gonococcal infections include salpingitis and infertility.
Non-Venereal Infections
- Gonococcal bacteremia can occur.
- Ophthalmia neonatorum is an eye infection of newborns transmitted from the mother during labor.
- Gonococcal vulvo-vaginitis can affect young girls due to contaminated toilets.
Antigenic Variation and Virulence Factors
- Antigenic variation occurs in Gonococci.
- Virulence factors include pili (fimbriae) and IgA protease.
Diseases Caused by N. Gonorrhea
- Gonorrhea is a disease caused by N. gonorrhea.
- Gonococcal urethritis is a specific urethritis, a sexually transmitted disease that affects both males and females, manifesting with discharge and dysuria.
Urethritis
- Urethritis is defined as inflammation of the urethra, accompanied by dysuria, frequency, urgency, and itching.
- Classification of urethritis includes gonococcal urethritis (specific) and non-gonococcal urethritis (non-specific).
Causes of Urethritis
- Gonococcal urethritis is caused by N. gonorrhea.
- Non-gonococcal urethritis is caused by:
- Chlamydia trachomatis
- Mycoplasma genitalium
- Ureaplasma urealyticum
- E. coli
- Acinetobacter
Characteristics of Urethritis
- Gonococcal urethritis has a short incubation period, sudden onset, and profuse discharge with pus.
- Non-gonococcal urethritis has a long incubation period, gradual onset, and little discharge with pus.
- Specimens of gonococcal urethritis contain gonococci, while those of non-gonococcal urethritis do not.
Morphology of Neisseria Gonorrhoeae
- Neisseria gonorrhoeae are Gram-negative diplococci, arranged in pairs with a kidney-shaped appearance.
- They are present intracellular and extracellular in pus cells.
This quiz covers the symptoms, complications, and transmission of gonococcal infections, including cervicitis, urethritis, and ophthalmia neonatorum.
