HLTH 2501: STDs Flashcards
STDs
encompass a broad range of infectious diseases that are spread by sexual contact; some are declining but some are rising
concerns of STDs
recurrent infections, more than one may be present at a single time, spread is easy due to some being asymptomatic, some have no cures, there are risks associated with infections, fetuses can become infected, and partners can be hard to trace
most common STD
chlamydia
leading cause of PID
chlamydia
causative agent in chlamydia
C trachomatis which is a gram-negative obligate intracellular parasite that requires s host cell to reproduce
how does chlamydia develop?
the infectious agent invades the epithelial tissues of the urogenital tract, causing inflammation
lymphogranuloma venereum
occurs when C trachomatis can enter the lymph nodes and cause infection here
females and chlamydia
they are asymptomatic until PID develops; some may experience urethritis, bartholinitis, servictis, or salpingitis
men and chlamydia
urethritis (dysuria, itching, and white discharge from the penis) and epididymitis (painful, swollen scrotum, fever, and swollen lymph nodes); rectal inflammation (proctitis) may occur in those practicing anal intercourse
newborns and chlamydia
can be infected during passage through the cervix and vagina, resulting in conjunctivitis or pneumonia
treatment for chlamydia
tetracycline or azithromycin
STDs seen in conjunction
chlamydia and gonorrhea
treatment for chlamydia and gonorrhea
doxycycline and azithromycin
gonorrhea causative organism
N gonorrhoeae which is a gram-negative aerobic diplococcus that uses the pili to attach to epithelial cells and then damage th mucosa
most common site of gonorrhea in males
the urethra, resulting in dysuria and a purulent urethral discharge
most common site of gonorrhea in females
the endocervical canal (asymptomatic) or the skene and bartholin glands, causing thick greenish, yellow, or creamy white discharge
gonorrhea complications
in men in can persist to epididymitis and for women PID or gonococcal arthritis
newborns and gonorrhea
may become infected during birth resulting in an eye infection called ophthalmia neonatorum
orogenital contact of gonorrhea
can lead to pharyngitis, tonsillitis, or lymphadenopathy
treatment for gonorrhea
is often resistant to common antibiotics like tetracycline or penicillin
syphilis causative organism
is treponema pallidum, an anaerobic spirochete
syphilis primary stage
is identifiable by the presence of a chancre where organisms reproduce (this is asymptomatic in females); this heals on its own
