Dental spirochaete, shorter and with shallower coils than Treponema pallidum, and more easily stained.  

Dental spirochaete, larger and more actively motile than Treponema pallidum.  

Rabbit-infecting treponema, morphologically indistinguishable from Treponema pallidum, and a hazard when using rabbits for propagation of the latter.  

Pathogenic non-venereal treponeme morphologically as Treponema pallidum but immunologically distinct. Causes pinta, a disease with many of the aspects of syphilis, and which is diagnosed and treated by the same methods as the venereal disease. The causative agent of pinta, an infectious disease of the skin.  

Benign treponema found in normal genital secretions. The spirals are broader than with Treponema pallidum, and the body thicker and more glistening.  

Canned tomato juice/casein hydrolysate/milk agar, used for lactobacillus counts on saliva (in dental bacteriology).  

Those which can endure (but not grow) at high temperatures—for example, many spore-bearers.  

Index of the heat resistance of a microbial species. Normally the lowest temperature which, applied to a standard suspension of the organisms under moist conditions, causes their death in 10 minutes. The thermal death point of the non-sporing mesophilic bacteria may lie between 50°and 65°C, and between 100°and 120°C for most spore-bearers. Using dry heat…

Enrichment medium for the isolation of salmonella species, consisting of nutrient broth plus chalk, iodine, sodium thiosulphate and phenol red indicator.  

The main component of Cl. tetani exotoxin, a necrotoxin of most pronounced potency. A toxin produced by tetanus bacilli in an infected wound. The toxin diffuses along nerves, causing paralysis, and may reach the spinal cord and brain, when it causes violent muscular spasms and the condition of lockjaw. A component of the toxin produced…
