摘要: We studied mating behavior of 2 pairs of South China tigers (Panthera tigris amoyensis) using focal sampling and all occurrences sampling in the Shanghai Zoological Park, November 2004-March 2005. Mating behaviors occurred mostly during 9:00-11:00 and 13:00-17:00, with a peak at 13:00-15:00. The female displayed solicitating behavior before mating, and if successful in soliciting a male, groveled on the ground while awaiting being mounted. The mating period was 5-6 days and mating bouts averaged 25.6±12.1 seconds. We found are a highly significant difference in mating duration between the 2 males (one-way ANOVA). We also documented some abnormal mating behaviors of the males, such as lack of sexual impulse, incapable of mounting, and excessive vigilance.
摘要: 钩端螺旋体病(Leptospirosis)为致病性钩端螺旋体引起的人畜共患传染病,在世界范围内分布(Levett, 2001),可感染鼠科、猴科和犬科等多种动物(Desvars et al., 2012)。人或动物通过接触带菌动物的粪便、尿液污染的水和土壤而感染(娄银莹等,2019),可造成黄疸、急性肾功能衰竭、出血性素质和严重肺部疾病等,因血清型或地域不同,呈现不同的临床表现(McBride et al., 2005;Goldstein et al., 2006)。
