Renal Coccidial Infection in North American Northern Gannets (Morus bassanus)

Description
Summary:	We identified by light microscopy micro- and macrogametes and oocysts of renal coccidia in 78 of 220 (35.5%) Northern Gannets (Morus bassanus) from the western North Atlantic population. This infection was not considered clinically significant in any of the affected birds, although the potential effect of this parasite in breeding colonies, particularly among nestlings, is unknown. Analysis of the 18S rRNA gene from frozen renal tissue by PCR and subsequent sequencing revealed 95.6% identity with Eimeria auritusi from Double-crested Cormorants (Phalacrocorax auritus), suggesting a novel Eimeria sp. in the Northern Gannets.
