Respiratory cryptosporidiosis in the acquired immune deficiency syndrome. Use of modified cold Kinyoun and Hemacolor stains for rapid diagnoses
P. Ma, T. G. Villanueva, D. Kaufman and J. F. Gillooley
We report three cases of primary intestinal cryptosporidiosis with
bilateral interstitial pneumonia. The diagnoses were made using two rapid
(one-minute) staining procedures, modified cold Kinyoun's solution and a
Hemacolor set, on touch preparations of lung biopsy material, sputum, and
stool. Intracellular cryptosporidia oocysts in alveolar macrophages suggest
possible hematogenous spread of this agent. Opportunistic cryptosporidiosis
should be included in the differential diagnosis of pneumonia in patients
with acquired immune deficiency syndrome.
