Serological studies on leptospirosis in domestic animals in Quebec.

During a period of 30 months, from January 1977 to June 1979, Leptospira agglutinins were detected in 355 (6%) of 5841 bovine sera, 52 (10.1%) of 511 porcine sera, one (5%) of 20 equine sera and one (12.5%) of eight canine sera. Bovine, porcine and equine sera reacted predominantly with L. pomona. Reactors to L. hardjo/sejroe, L. icterohaemorrhagiae and L. grippotyphosa were also detected in cattle. One porcine serum reacted with L. grippotyphosa and one canine serum with L. icterohaemorrhagiae. Al the sera originated from suspected cases of leptospirosis.

[Rate of precocious sexual intercourse in adolescents in disadvantaged socioeconomic environments. (University of Quebec in Montreal)].

This article presents a preliminary study, a descriptive one, on the sexual intercourse precocity rates at adolescence. 765 male adolescents francophones, 13 years old, from low economic status answered the QAS, questionnaire on aspects of sexual life including. The results show that 11.3% of subjects are sexually active by 13 years old. The first sexual partner is known from many months to many years from the majority of subjects. The majority (61.8%) of the non-sexually active subjects of the research would be near to transit to the first sexual intercourse if we consider the results of our predictive measure of the transition. Discussed at the light of the literature, these results show that early sexual behaviors are: 1) a concrete reality for an important proportion of male adolescents from low economic status; 2) to consider in the future in terms of research priority.
