- near lower lip or face
- primarily causes oral-labial lesions
What are some characteristics of HSV (herpes simplex virus) type 2 ?
- 90 to 95% of all genital herpes lesions
- lives in sacral dorsal root ganglia
- base of the spine and tends to reoccur in the genital area
What bacteria causes Syphilis ?
treponema pallidium
What are the characteristics of stage 1 Syphilis ?

- noncurable
What are some characteristics of Treponema Pallidum ?
causes syphilis
- gram (-) bacterium
- spirochete in shape
- usually in mucous membranes when infecting someone
How does antibiotic resistance happen ?
- lots of germs and some are drug resistant
- antibiotics kill the bacteria causing the illness as well as the good bacteria protecting the body from infection
- the drug resistant bacteria is now able to grow and take over
- some bacteria give their drug resistance to other bacteria
When getting tested for Chlamydia what other STI are they also tested for ?
Neisseria Gonorrhoeae
- tested for them together and vice versa but have different treatment plans
Why is a definitive diagnosis important for Chlamydia ?
symptoms of chlamydia resemble those of Gonorrhea
What are some general characteristics of Chlamydia ?
- gram (-) obligate intracellular organism
- non motile
- ARE NOT VIRUSES
- steals energy from its host because they can’t produce their own
- women and men often are asymptomatic
- have to be within the cell of an organism
Which Chlamydia in the whole family causes the STD pathogen ?
C. Trachomatis
What diseases can Chlamydia Trachomatis cause ?
- trachoma
- inclusion conjunctivitis
- LGV (lymphogranuloma vernereum)
- PID
In how many hours does transition of EB to RB occur with Chlamydia ?
6-12 hrs
In how many hours does replication of Chlamydia occur ?
12-24 hrs
In how many hours does RBs reorganize back to EBs ?
24-36 hrs
In how many hours does lysis or extrusion of Chlamydia occur ?
48-72 hrs
With Chlamydia Trachomatis how do the cells appear under a microscope ?
- chlamydia infected cells appear pink while uninfected cells appear blue upon staining with a dye
What can happen to untreated Chlamydia in females ?
permanent damage to fallopian tubes
- can lead to future infertility and increased risk of ectopic pregnancy
- during pregnancy it can increase a woman’s risk of preterm labor
What are some symptoms of Chlamydia ?
- vaginal and penal discharges
- abdominal pain
- pain during micturition (UTI) symptoms
What can be passed onto the baby with a mother with chlamydia ?
eye damage and pneumonia in newborns

What are chlamydia symptoms in men ?
- penile discharge
- burning/painful urination
- testicular swelling
What are chlamydia symptoms in women ?
- vaginal discharge
- burning/painful urination
- bleeding between periods
What can untreated STDs lead to ?
PID (pelvic inflammatory disease)
Why may men have lower chlamydia report rates ?
men can report less chlamydia testing or may be more likely to be asymptomatic
What is Trachoma ?
bacterial infection that affects your eyes
- leading preventable cause of blindness worldwide
- most blinding trachoma occurs in poor areas of Africa
How is Trachoma spread ?
spreading through contact with the eyes, nose or throat secretions of infected people, and from handkerchiefs
- contagious
What causes adult inclusion conjunctivitis ?
sexually transmitted Chlamydia trachomatis
- a follicular trachomatis
What does conjunctival scraping determine ?
whether chlamydia is present in cells taken from the conjunctiva
Where is adult inclusion conjunctivitis rarely got from ?
contaminated, incompletely chlorinated swimming pool water
What is Trichomoniasis ?
very common STC caused by the infection with a protozoan parasite called Trichomonas vaginalis
What bacteria causes Trichomoniasis ?
Trichomonas Vaginalis
What are the symptoms of Trichomoniasis in females ?
most people are asymptomatic
- grey or yellowish vaginal discharge

- discharge from urethra
- burning during urination or after ejaculation
