The samples were collected from three sampling points （BM l-south, BM l-north and BMl-west） in Butrinti lagoon located in the south of Albania. The examination confirmed incidence of this pathogen with average value 4.5%. Based on the results, high incidence was reported in winter with 6.7% of analyzed samples. The incidence of L. monocytogenes was also reported respectively in spring of 2009 with 4.35% and in autumn with 2.3% of controlled samples. There is no big difference in values of incidence of L. monocytogenes between summer and autumn. The northern part of the lagoon was more indicated by contamination of L. monocytogenes. Examination of 67 samples of M. galloprovincialis, collected in the northern part of this lagoon, showed five cases or about 7.5% of them to be confirmed as positive. Referring to the study results, periodic controls of the sea products, particularly of live bivalve mollusks, for presence ofL. monocytogenes remains a necessary objective of food inspection in Albania.展开更多
Using the circle method and sieves, the author proves that a positive proportion of positive integers can be represented as the sum of four cubes of primes.
