    • The Treponema of medical importance is the causative agent of syphilis
    Syphilis a disease that, when acquired through
    sexual contact is called VENEREAL SYPHILIS
    Venereal syphilis is caused by the microorganism

    •Primary
    •Secondary
    •Latent
    •Tertiary/Neurosyphilis
  • Primary
    • Lesions appear in genitalia or mouth
    • AKA “Hard chancre or hunterian chancre
    Sore chancre - painless that develop on the site
    where the bacteria enter our body
    • Heal on their own after 3 weeks to 6 weeks but
    infection can still spread in body
    • Occur in 3 weeks
    10-90 days
    • High contagious
    Painless Sore at the site of infection anus, vagina,
    rectum and penis
    Easily treat with medicine
  • Secondary Stage
    •"CONDYLOMA LATA”
    • Appears all over the body
    • Characterize by rashes
    • Appear 2-4 week
    • Appear before it heals
    • Highly contagious
    • Occur that spread throughout the body
    • Rough red, reddish brown rashes, swollen lymph
    nodes, fever, sore throat, headache, body ache,
    extreme tiredness/ fatigue
    • Commonly includes in the palms, sole, foot, hands
    • The symptoms will go away even with no treatment
    but if you're not get treated the infection will get
    worse.
  • Latent“GUMMAS” • No sign and symptoms • Appear through serological test or blood test • The syphilis bacteria are still alive • Not contagious but can still affect the heart, brain, bone and other organ of body • Can last for years • Not everyone who has syphilis can enter this stage of infection
  • TertiaryNeurosyphilis
    Most destructive stage of syphilis if untreated • May begin as early as 1 yr. after infection or anytime during a person lifetime • Start if the symptoms in secondary stage disappear • The infection starts to affects organ • Symptoms: depends on the complications • GUMMATA - large wound in our organs • CARDIOVASCULAR SYPHILIS- heart, blood vessels • NEUROSYHLIS - affect nervous system, affects muscle movements, blind, dementia  
  • Congenital Syphilis
    • Transmission from syphilitic mother to the fetus through the placenta
  • Treponema pertenue
    •The causative agent YawsYAWS - disease of the bone and skin through direct contact
  • Treponema carateum
    •The causative agent of CARATE or PINTAPINTA - primarily restricted to skin • Characterized by hyperpigmentation of lesions • 1-3 weeks incubation period • Initial lesions: enlarged plaques persist for month to years • Late: disseminated, recurrent hypopigmentation or depigmentation of skin lesions, scarring and disfigurement • Transmitted by direct contact with skin lesions • Primitive tropical areas • Hypopigmented Skin Lesions of Pinta: depigmentation is commonly seen as a late sequel with all treponemal diseases
  • LEPTOSPIRES / LEPTOSPIRA
    Thin and fine coil structure • Causative agent WEIL’S DISEASE • WEIL’S DISEASE - an infectious disease transmitted to man from a wide variety of animals
  • Leptospires/ Leptospira
    • The Genus Leptospira contains a large number of species that are saprophytic and harmless to both humans and animals. • Several species, however, are parasitic and caused infections characterized by their effect on the liver, kidney, lungs, and meninges.  
  • Other Name of Leptospires/ Leptospira
    Swineherds disease • Pretibial fever • Fort braggs fever • Autumnal fever • Conical fever
  • Species of Leptospires/Leptospira
    •Leptospira Biflexa •Leptospira Interorgans- hin coiled shape-like a question mark
  • Borrelia
    • “Blood spirochetes” • The Borrelia is the largest of the pathogenic spirochetes, ranging from 10-30μm (micrometer) in
    length and 0.3-0.7μm in width.
    • They are actively motile, exhibiting lashing, twisting
    movement.
    • They have irregularly spaced coils.
