The bovine filarial parasite Onchocerca armillata contains the endosymbiont Wolbachia and elicits a limited inflammatory response.

摘要

It was determined that the filarial parasitic nematode of West African cattle O. armillata carries in its tissues Wolbachia, an endosymbiotic, Rickettsia-like bacteria. The host inflammatory cell environment around the adult worms is dominated by macrophages and fibroblasts. Thus, O. armillata appears to be protected from eosinophil degranulation, but the mechanism involved is unknown.
