Agentes bacterianos responsables de infecciones secundarias a procesos dermatológicos causados por ácaros en caninos y felinos domésticos

Abstract

The skin fulfills indispensable functions, the most important being that of a protective barrier; composed of several layers and microbiota; and that for various factors whether mechanical, biological, or underlying pathologies this extensive organ suffers damage in its structure thus appearing the lesions that are initial or primary and secondary as a consequence of the advance of the first ones. In the daily clinic many are the cases of pets with skin problems; being more frequent in dogs than in cats. One of the main causes of the dermopathies are the ectoparasites like the mites, one of them, Demodex spp that being own in the skin of the mammals and depending on the conditions of health of the animal can get to be pathogenic and other mites like Sarcoptes scabiei, Otodectes cynotis, Notoedres cati behave as opportunists causing alterations that become the entrance door of microorganisms such as Escherichia Coli and Proteus spp and reason for the cutaneous microbiota mainly bacteria such as Staphylococcus spp, Streptococcus spp. and Pseudomonas aeruginosa go from being part of the skin to being pathogens, thus originating bacterial infections or pyoderms; these infections have been classified according to the affected surface; thus having surface pyoderms that affect the epidermis, superficial pyoderms causing damage to the epidermis and hair follicle and the deep ones whose lesions reach the dermis. To determine what the pyoderms are and to be able to apply an adequate treatment, it is necessary to use complementary tests such as cytology and bacterial cultures.
