White Spots

Swiss cheese made from fully pasteurized milk developed white spots during hot room stay. This cheese was bitter and eye development was generally retarded. Streptococcus faecalis subsp. liquefaciens was isolated in high numbers from the spot; it caused bitterness in milk cultures with complete dissolution of the milk clot. The isolate was inhibitory to propionibacteria and Lactobacillus fermentum; CO2 production by Propionibacterium was depressed in broth culture in the presence of the S. faecalis subsp. liquefaciens isolate.

Challenge Control

A total of 35 pigs aged 15 weeks old, and 21 pigs aged 8 weeks old were divided into 7 groups. Groups 1 and 2 were uninfected and challenge control groups, respectively. Groups 3 and 4 were infected weekly with 6 increasing doses of Ascaris suum eggs, and group 4 was additionally treated with pyrantel. Groups 5, 6, and 7 were immunized weekly with the 14, 42, or 97 kDa fractions from adult worms, respectively. Animals of groups 2–7 were challenged with 10 000 A. suum eggs 7 days after the last infection/immunization. Serum was sampled weekly and specific IgG1, IgG2, and IgM responses were measured. Pigs of groups 5, 6, and 7 showed high IgG1 and IgG2 responses especially against adult worms antigens, while infected groups had high IgG1 and IgM responses, especially against larva. The IgG1 responses were negatively correlated to the numbers of larvae in the lungs, and positively associated with the liver white spot numbers. There was a positive correlation between IgG2 and the numbers of white spots and lung larvae, while IgM was negatively correlated with these parasitological measures. These findings are discussed and it is suggested that acquired resistance against A. suum larvae is correlated with the induction of IgG1 and IgM, and not with IgG2, and that future vaccination protocols may focus on inducing the Th2 activity.

White Spots

The aim of the present study was to describe a clinical protocol for the treatment of white spots with the use of an abrasive material. A four-year-old patient presented with a white spot on tooth 51 and a white spot associated with a carious lesion in the cervical region of tooth 52. Treatment was planned with microabrasion and restoration of the upper right lateral incisor. Prophylaxis was first performed, followed by protection with a dental dam and the application of the abrasive material (silicon carbide and hydrochloric acid 6%). Five applications were needed to remove the spots. The restoration of the upper right lateral incisor was then performed with a resin composite. A good esthetic outcome was achieved and both the patient and her guardians were satisfied with the results. Microabrasion is a conservative treatment option that achieves satisfactory results with regard to tooth color.
