JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 1104 OP 1106 DO 10.1136/jcp.41.10.1104 VO 41 IS 10 A1 Shepherd, R C A1 Reed, C L A1 Sinha, G P YR 1988 UL http://jcp.bmj.com/content/41/10/1104.abstract AB Forty nine patients (19 adults and 30 children) with oocysts of Cryptosporidium in their faeces had repeated stool specimens taken until oocysts could no longer be identified. They were found in the stools up to 35 days after the onset of symptoms in one patient, but most had stopped shedding them by 20 days. In 25 of the 49 patients in whom symptoms could be compared with the shedding of oocysts, 19 (76%) had symptoms corresponding to the shedding period while symptoms persisted in four (16%) after shedding had stopped.
