Toxoplasmosis in a Bar-Shouldered Dove (Geopelia Humeralis) From the Zoo of Clères, France

Jacques Rigoulet et al. Parasite.

Abstract

Toxoplasmosis causes mortality in several avian species, especially passerine birds. Toxoplasmosis was diagnosed in a bar-shouldered dove (Geopelia humeralis) found dead at the zoo of Clères (France). The bird had necrotizing pneumonia and nephritis with intralesional tachyzoites of Toxoplasma gondii. The diagnosis was confirmed by immunostaining with polyclonal rabbit T. gondii antibodies and by transmission electron microscopy. To our knowledge, the bar-shouldered dove is a new host record for T. gondii.

Toxoplasma gondii in a bar-shouldered dove, lung. Two tachyzoites enclosed in a parasitophorous vacuolar membrane (pvm). Note conoid (co), micronemes (mn), rhoptries (ro) with honey-combed contents, and a nucleus (nu) in each tachyzoite. The parasitophorous vacuole has membranous tubules. Transmission electron microscopy.
