RESUMEN
Coronaviruses have tremendous evolutionary potential, and three major outbreaks of new human coronavirus infections have occurred in the recent history of humankind. In this paper, the patterns of occurrence of new zoonotic coronavirus infections and the role of bioveterinary control in preventing their potential outbreaks in the future are determined. The possibility of SARS-CoV-2 infection in companion animals is considered. Diverse human activities may trigger various interactions between animal species and their viruses, sometimes causing the emergence of new viral pathogens. In addition, the possibility of using probiotics for the control of viral infections in animals is discussed.
RESUMEN
Despite significant advances in andrology, the problem of penile cavernous fibrosis remains not fully understood. Many studies on the epidemiology of erectile dysfunction have been published, but consensus on the place and role of this pathology in the structure of sexual disorders has not yet been reached. The data obtained at different time intervals and in different geographical areas are strikingly different. Also, the role of organic disorders in the penis, including fibroplastic changes, in certain etiological factors has not been determined. In addition, the relationship between etiological factors and morphological changes in penile tissues is disputed due to the small amount of data obtained from the pathohistological study of human penis biopsies. This review is devoted to the systematization of epidemiological data and etiological factors of cavernous fibrosis, the definition of the relationship between them, the analysis of clinical and experimental studies, which study the relationship between the degree of severity of damaging agents and the formation of typical fibrogenic reactions.
