Phycomycosis

 

an infectious disease of farm animals (mainly the young), as well as mink and fish, caused by pathogenic fungi of the family Mucoraceae. The disease also affects humans. Infection takes place through the respiratory organs, the alimentary canal, injured skin, or mucous membranes, in which nodules of tissue (granulomas) and suppurative ulcers form. The disease affects the viscera, mainly the intestine and lungs, the skin of the extremities and head, and the mucous membranes of the nose and its accessory sinuses. Depending on the site of infection, animals may suffer from diarrhea, exhaustion, swelling of the subcutaneous lymph nodes, ulceration of the skin and nasal septum, and miscarriage.

An effective means of treating phycomycosis has not been developed. Prevention mainly includes the observance of sanitary conditions in housing and feeding animals. Supervising the quality of feed is especially important.

Entre los diagnosticos diferenciales se encuentran: pythiosis cutanea, habronemosis cutanea y sarcoide fibroblastico; por lo que se puede realizar el diagnostico basado en la exclusion por las caracteristicas clinicas y epidemiologicas de la lesion; es asi como la pythiosis cutanea presenta forma de crater, pruriginosa, fibrinosanguinolenta, con trayectos fistulosos y salida de material caseificado llamados Kunkers (Cardona et al., 2013a; 2014; 2016a), la habronemosis es una lesion en forma de crater, seca y con salida de pequenos materiales blanquecinos parecidos a granos de arroz que corresponden a larvas muertas del parasito (Cardona et al., 2016b; 2017), mientras que el sarcoide fibroblastico es una lesion exofitica, lisa, brillante y seca (Cardona et al., 2013b).
