[Morphometric characteristics of tularemia infectious process in the organism of immunized guinea pigs].

Aim: Morphometric characteristic of organ and system state of guinea pigs immunized with live tularemia vaccine during infection with virulent culture of tularemia.

Materials And Methods: Morphometric study of histological material from immunized guinea pigs infected subcutaneously at day 30 with a culture of virulent tularemia strain was performed. A standard scheme of sampling and preparation of morphological material and staining of final semifine section with hematoxylin and eosin, impregnation with silver by Masson in Gamperl and Grimelius modificationwas used. Morphometric study was performed by using "Densitomorphometry" program.

Results: Morphometric parameters that characterize functional state of organs and systems in immunized, immunized with consequent infection and infected guinea pigs were established. Reactive processes that take place in the infected animal organism against the background of prior immunization fit into the range of adaptation-compensation reactions.

Conclusion: The morphometric study carried out allowed to adequately evaluate the state of functionally important systems of the organism of experimental animals, this allows to consider perspective the wider use of morphometric analysis in experimental morphology.
