SOME PROBLEMS IN THE EPIDEMIOLOGY OF DEEP MYCOSES
Abstract
The soil is the main factor in the transmission of the causative agent of deep mycoses. Having entered the soil from the source of infection - an animal (and possibly also man) with excretion, and probably by other routes, the causative agents of deep mycoses, under specific conditions, may be preserved in it for a long time. Spores of the causative agents are brought into the organism of man primarily with soil dust (air-dust mechanism of infection) or when carrying out excavation work in natural foci, in the event of disturbance and contamination of outer covering layers (contact route of transmission). Considering that clinically deep mycoses sometimes proceed with symptoms of damage to the gastro-intestinal tract (ulcerative colitis), the fecal-oral mechanism of transmission is not excluded. In animals the routes of infection are more diverse: digging of burrows, eating infected feed (plants), carcasses, inhalation of infected dust, etc. Transplacental transmission of histoplasmosis was observed in horses. It is also possible to assume the transmission of infection from animal to animal by blood-sucking arthropods, ticks in particular.
