genetic variation and widespread dispersal of nosema ceranae in apis mellifera apiaries from argentina. | using molecular techniques, we documented the presence of nosema ceranae in honeybees (apis mellífera) from argentina. samples were collected from a. mellifera colonies in 38 districts of buenos aires province, argentina. molecular characterization was achieved with a multiplex pcr-based method, which allows parallel diagnosis of n. ceranae and n. osema apis. n. ceranae was identified in all the samples analyzed. moreover, coinfections with n. apis were detected in balcarce and maipú districts. ... | 2011 | 21808980 |
