Intestinal and extraintestinal Isospora belli infection in an AIDS patient. A second case report.

A 30-year-old black female, from Burkina Faso, had AIDS in 1990. She died in March 1993 following a cachexia secondary to a chronic intestinal isosporiasis. The autopsy revealed a massive parasitic infection by I. belli of the small intestine mesenteric and mediastinal lymph nodes and liver and spleen. The parasite stage observed in extra intestinal sites corresponded to unizoite tissue cysts. This is the first report of I. belli infection in liver and spleen.

Isospora automoli, a new coccidian parasite (Apicomplexa: Eimeriidae) from the buff-throated foliage-gleaner Automolus ochrolaemus and the olive-backed foliage-gleaner A. infuscatus from South America.

A new species of isosporan parasite is described from the faecal contents of the buff-throated foliage-gleaner Automolus ochrolaemus and the olive-backed foliage-gleaner A. infuscatus collected in the rainforests of eastern Ecuador. Sporulated oöcysts are subspherical to ovoidal, 23.4 x 21.3 (18-28 x 17-24) microns, colourless, with a smooth, double-layered wall with the inner layer darker and thinner; the shape-index (length/width) is 1.1 (1-1.22). Oöcysts contain one polar granule, but lack a micropyle and an oöcyst residuum. Sporocysts are ovoidal, 15.4 x 9.9 (14-17 x 8-11) microns, with a smooth single-layered wall and a small nipple-like Stieda body attached to a small, inconspicuous, acentric substieda body. Sporozoites are vermiform with one prominent posterior, refractile body (c. 4 x 5 microns), and a centrally located nucleus of equal size. Sporozoites are randomly arranged in the sporocysts with a subspherical sporocyst residuum composed of coarse granules.
