10. Dark-field photomicrograph of spirochetes

11. Structure of spirochete

12. Structure of spirochete cell

13. Bacterial flagella

14. Electron micrographs of spirochetes Treponema Borrelia Leptospira

15. Phase contrast photomicrograph of free-living spirochete

16. Spirochetes morphology Treponema Leptospira Borrelia

19. Treponemes in the specimen from a patient with syphilis

22. Electron micrograph of the Tr.pallidum attached to cells . Tip of spirochete Host cell

25. Congenital syphilis A profuse nasal discharge that obstructs breathing Hutchinson's teeth Consequences: from mild to the extremes of spontaneous miscarriage or stillbirth Signs - nasal discharge , skin eruptions and loss, bone deformation, and nervous system abnormalities. In the late form - formation of Hutchinson's teeth

26. Nonsyphilitic Trepanematoses Yaws (frambesia tropica) Bejel (endemic syphilis)

28. Immunofluorescence microscopy. Treponemes in the specimen from a patient with syphilis

32. Scanning electron micrograph of Borrelia

38. Borrelia in blood smear Romanowsky-Giemsa staining

39. The main reservoir – small mammalians (mice), upon which the nymphs feed. Large mammalians (deer), are an obligatory host in the tick’s life cycle but are not an important reservoir of the Borrelia. There is no human-to-human spread
