The life course of affective episodes was determined for 95 consecutively admitted patients from eastern India fulfilling RDC criteria for definite mania during the current episode, using SADS-L interviews. There was a significantly greater frequency of manic compared to depressive relapses. Presentation as recurrent mania was very common. The total numbers of affective and manic episodes were significantly higher among those with recurrent mania and in cases where the first illness episode was manic.

Horizontal transmission of Campylobacter jejuni amongst broiler chicks: experimental studies.

Horizontal transmission of Campylobacter jejuni was investigated in campylobacter-free broiler chicks. One hundred and twenty chicks housed individually, were provided with water containing 10(2)-10(9) c.f.u./ml C. jejuni. Colonization was rapid [47 of 73 (64%) positive cloacal cultures within 3 days and 65 of 73 (89%) within 7 days], dependent on C. jejuni strain and inoculum size but independent of chick age. Groups of 5-24 chicks in isolators were exposed to C. jejuni-contaminated water or colonized seeder chicks. Transmission occurred in 2-7 days concurrent with a gradual increase of C. jejuni in litter, water and feed. Environmental samples were culture-negative within 3 days following removal of colonized chicks. Treatment of 1-day-old chicks with adult caecal microbiota did not affect colonization. Treated and control chicks were all C. jejuni-positive within 3 days of seeder challenge.
