ABSTRACT

A total of 60 samples of dry sausages were analyzed (50 of "salami" and 10 of "chorizo" "candelario" type) obtained at random in markets authorized for their commercialization, for the purpose of evidencing the presence of bacteria of the genus Listeria (Listeria monocytogenes and Listeria spp.). The results obtained in salami were the following: 10 (20%) isolates of Listeria spp., were characterized: 1 (2%) strain as L. monocytogenes type 1, 7 (14%) strains as L. innocua, 2 (4%) strains as L. welshimeri. In chorizo candelario type 6 (60%) isolates of Listeria spp., were characterized: 2 (33%) strains as L. monocytogenes type 1 and 4 (66%) strains as L. innocua. The total percentages of isolations were: 26.6% of Listeria spp., 5% of L. monocytogenes type 1, 18.3% of L. innocua and 3.3% of L. welshimeri. In conclusion, we consider that methodologies of control must be developed and implemented in order to guarantee the inocuity of these products.

ABSTRACT

Listeria monocytogenes has been recognized as a bacteria that produces severe illness in animals and humans. Considering the importance of the presence of L. monocytogenes in soft paste cheeses, a study of diverse cheeses from supermarkets of direct sale to the public was carried out. From the 35 analyzed cheeses, 4 strains were isolated (11.4%). The result of the serological study showed that all the strains corresponded to the serotype 4. The proteic profiles of the isolated strains showed similarity with the used pattern (4b). Several authors reported the importance of L. monocytogenes as contaminant in foods ready to eat like the soft paste cheeses. Thus, it must be remarked the importance of the good handling practices in the production, transport, refrigeration and exhibition of this product.

ABSTRACT

OBJECTIVES: This study compared the frequency, glucose tolerance test results, and parameters of blood glucose control in twin and singleton pregnancies associated with gestational diabetes mellitus and carbohydrate intolerance. STUDY DESIGN: Twin and singleton pregnancies associated with gestational diabetes mellitus and carbohydrate intolerance were compared as follows: frequency, maternal age, weight, 1-hour screen, glucose tolerance test results, posttreatment blood glucose values, insulin requirement, and insulin dose. Statistical analysis included the chi(2) and Student t tests. RESULTS: Gestational diabetes mellitus was increased in twins (7.7% vs 4.1%; P <.05). The maternal weight at first visit was significantly less, and the 3-hour glucose tolerance test value was significantly greater than that for singletons. The other parameters were not different. CONCLUSIONS: There is a significant increase in the incidence of gestational diabetes mellitus and disturbance of the 3-hour glucose tolerance test in twin pregnancies. However, insulin requirements were not different, suggesting a mild disturbance of carbohydrate tolerance that was effectively managed by the strategies used to achieve blood glucose control in singletons.
