Stool specimens from attendees were positive for oocysts of the coccidian parasite Cyclospora cayetanensis, and an epidemiologic investigation was begun by the Philadelphia Department of Public Health and the Centers for Disease Control and Prevention (CDC).
The prevalence of infection was calculated for each parasite and for each sampling event, and the infection intensity was assessed for the gill coccidian, the RLO, and the hemocytic infiltration foci.
The health issues included ear mites, ear infections, giardia, nasal discharge, pneumonia, kennel cough, parasites, vomiting, diarrhea, parvovirus, roundworms, coccidian, lethargy, congenital defects and hypoglycemia.

The higher cecal lesion score that was observed in the control group correlates well with the higher mortality in the same group, as Eimeria tenella is usually considered the most pathogenic of the coccidian parasites and the mortality due to coccidiosis is usually associated with this species (McDougald, 1998).
Results of the study demonstrated equipotent efficacy of pure berberine in comparison to that of standard drug amprolium on the basis of reduction in coccidian oocyst output, body weight gain of chicken and feed conversion ratio.
The entire 18S rRNA gene (1,796 bp) was obtained from 2 DNA fragments amplified by PCR from DNA extracted from 3 fecal specimens by using procedures and primers for genetic analysis of coccidian parasites (4,7,8).
