Following is true of T. pallidum except -
Option 1 Culture: - Pathogenic treponemes cannot be grown in aificial culture media but are maintained rabbit testes. - However, nonpathogenic treponemes (e.g. Reiter treponemes) can be cultured in Smith Noguchi media Option 2 - It is actively motile. Endoflagella are responsible for motility of the bacteria. Option 3 Direct Microscopy: - Dark field microscopy - Direct IF staining from sample (DFA-TP) - Silver impregnation method Option 4 - TPI : Specific Treponemal test for diagnosis of Syphilis.
Systemic Bacteriology (Haemophilus, Yersinia, Spirochaetes, Ricketssia, Chlamydia, Mycoplasma and Miscellaneous Bacteria)
Can be maintained in rabbit testis
Motile by peritrichate flagella
To visualise, dark ground microscopy is used
TPI test is very-useful
Motile by peritrichate flagella
