Funding information: We are grateful to Dr. Mariano Higes for providing samples of bees infected with N. ceranae and N. apis . We would like to thank beekeepers who provided samples. We thank Gabriela Wlasiuk for improving this manuscript and the three anonymous reviewers for their comments. This study was funded by Instituto Nacional de Investigación Agropecuaria (INIA).  aABSTRACT. The microsporidium Nosema ceranae is an emergent pathogen of European honeybees Apis mellifera. Using a PCR-RFLP diagnosis, 29 samples of infected honeybees obtained in 2007-2008 (N = 26), 2004 (N = 2) and before 1990 (N = 1) were analyzed for the presence of Nosema apis and N. ceranae. Only N. ceranae was found in all samples, indicating that this species dispersed to Uruguay (and likely the region) at some time before 1990. The presence of N. ceranae in Uruguay is not associated with an increase of Nosemosis, and its role in colony loss seems to be irrelevant. © 2009 Elsevier Inc.
