Abstract:
Lechiguana is a disease of cattle characterized by large, hard, subcutaneous swellings that grow rapidly and result in death after 3-11 months in untreated animals. Cattle treated with antibiotics recover. The disease has been reported from five states in south and southeastern Brazil. Histologically, the lesion consists of focal proliferation of fibrous tissue infiltrated by plasma cells, eosinophils, lymphocytes and sometimes neutrophils. The primary lesion is an eosinophilic lymphangitis, which results in eosinophilic abscesses, with occasional rosettes containing bacteria in their centres. Much experimental and epidemiological evidence, reviewed in this article, supports the suggestion that lechiguana is caused by an association of Pasteurella granulomatis (syn: Mannheimia granutomatis) and Dermatobia hominis.
