Abstract


Beginning with November 2016 beekeepers from Timiș county reported bee colonies losses. During the winter months the situation became more the situation has become more severe, increasing losses of bee families. From November 2016, untill February 2017 were been received samples of dead bees from 23 different apiaries in Timiș county. The dead honey bees were analized in the way to discover what kind of causes produced all these losses. Was also proceeded to analyze the bacterial flora from bees intestine. Bacteriological examination of bees intestine and the cultivation on special medium of culture emphasized rich cultures of Paenibacillus larvae subsp. larvae (Bacillus larvae), etiologic agent for American foulbrood. These bacteria were been isolated from bee intestine in samples provided from 18 apiaries (78.26%). There are many causes of high degree of bee mortality in winter 2016-2017 but the isolation of Paenibacillus larvae subsp. larvae maybe was one of them.
