1 µm
0,8 µm
0,1 µm
0,5 µm
For cultivate Leptospira, the optimal temperature is:
28-30°C for non-pathogenic bacteria

10°C for pathogenic bacteria
No one anterior answer is correct
The incubation period for Leptospira is :
Few hours
Few days (2-3)
Few weeks
Many mounts
For cultivate pathogenic Leptospira it needs:
Usual culture media
Solid special media
Liquid special media
Semisolid usual media
Which of the following media is special for obtain Leptospira culture?
EMJH
Coagulated serum blood
Korthoff
Christensen semisolid agar
Which of the following media is special for obtain Leptospira culture?
Fletcher semisolid
Simmons semisolid agar
Hemolised blood agar
Uhlenhuth
Which natural ingredient is used in composition of Leptospira culture media?
Horse hemolised blood
Sheep blood
Egg yolk
Rabit serum blood
For estimate the quality of Leptospiral culture (the presence and abundance of the pathogen) usually is used :
Silver impregnation by Manouelian or Levaditi methods
Electron microscope examination
Dark-field microscope examination
Fontana-Tribondeau method
In the second part of Leptospirosis, the pathogen is present in:
Liver
Kidney (basinet)
Blood
Urine
In the septicemic Leptospirosis, for diagnosis:
Can be detected the specific antibodies in the serum blood
Can be detected the specific antibodies in the urine
Can be find the pathogen into the blood
Can be detected the pathogen in liver or tissues
After 7 days of initial injection, in the second part of Leptospirosis, the pathogen can’t be find in the blood of the infected host. How can be explained this situation?
The pathogen is very sensitive in febril stage of the disease and doesn’t support the high level of the temperature
The immune system reacts and the specific antibodies block the pathogen
The lifespan of Leptospira is limited to one weak
The humoral immune response, based on specific antibodies and complement system, destroy the pathogen

Always, this bacterium presents pathogenic properties
Select correct answers about Fusobacterium necrophorum!
It can be cultivated just in the presence of oxygen
It is a filamentous Gram negative bacteria
It can be find on the superficial mucosa and in intestinal tract of healthy organisms
It produces the neurotic process in affected tissues

Select the correct sentence about Chlamydia and Chlamydophila !
The origin of reticulate bodie is other reticulate bodies
Reticulate bodies reprensent the metabolic inactive form of the pathogen, placed inside to the cytoplasm of infected cells
