| Abstract: | Infectious factorial diseases of domesticated small animals are infection dependent diseases, whose pathogenesis is finally activated by additional, secondary factors, that influence the multiplying and spreading of latent and clinical symptomless infective agents present in the animals. These factorial diseases are not autonomous infectious processes, but only special types and courses of diseases by secondary activated infective agents. Secondary factors may be of exogenous origin (housing, climate, feeding, managing) or may arise by endogenic processes (immunity, resistance disregulations a.o.). In fur bearing animals and rabbits infectious factorial diseases arise by activation of latent, symptomless infections of mucosal membranes in the nose and oral cavity, in the intestinal tract, in the descending urinary tract and on the external skin. The majority of infection activating secondary factors go back on wrong housing conditions, extreme climate, malnutrition and simultaneous infections, but also animal specific situations and immunosuppression may influence the activation of latent infections. - Typical factorial diseases in fur bearing animals and rabbits are: the infectious coryza (Pasteurella multocida, Bordetella bronchiseptica) in rabbits, the Coli-dysentery and the enterotoxemia in rabbits and herbivorous fur animals, the ascending infections of urinary tract, particular in young male minks, and the different types of microbial dermatitis in all small animals. - In the prevention and control of infectious factorial diseases the improvement of housing and living conditions as well as feeding the animals with species conforming and nonobjectionable food are most important and essential measures. |
