| Gram variable to gram (-) rod, bacterial vaginosis, symptoms: asymptomatic, thin white-yellow discharge, odor, itching, burning lactobacilli are low/absent other microbes involved bacteroides, fusobacterium, mycoplasma | Gardenerella vaginalis |
| Gram (-), diplococcus symptoms: painful urination, discharge, PID, intermenstrual bleeding Virulence: fimbriae , LOS endotoxin can spread -> joints, meninges, heart, skin can cause neonatal conjunctivitis high resistance to antibiotics | Neisseria gonorrhoeae |
| Gram (-), obligate intracellular , coccobacillus disease: chlamydia, NGU symptoms: often asymptomatic, discharge, painful urination can cause: epididymitis, orchitis, salpingitis, PID, neonatal conjunctivitis | Chlamydia trachomatis |
| associated with high risk of cervical cancer serovars can cause lymphogranuloma venereum -> release pus through skin | Chlamydia trachomatis |
| Gram (-), spirochete Disease: syphilis sexual contact, congenital 1- hard chancre , 2- rash on palms, fever, swollen nodes, 3- latent, 4- gummas, cardiovascular damage, neurosyphilis, congenital syphilis- deformities, lesions passed during preg | Treponema pallidum |
| yeast infection, symptoms: inflammation, itching, thick white yellow discharge, odor opportunistic infection disruption of lactobacilli ( via antibiotic therapy) not an STI Virulence factors: can adhere to host cells, form biofilms, | Candida spp |
| Most common nonviral STI Flagellated protozoan w/ undulating membrane amoebaid shape (oval) found only as trophozoite ( no cysts) | Trichomonas vaginalis |
| Virulence factors : adhesins, cable of phagocytosing other microbes of the normal microbiota symptoms: itching, irritation, discharge, burning associated w/ pregnancy complications such as preterm birth | Trichomonas vaginalis |
