A spreadsheet population dynamics model was constructed to evaluate the impact of female dog sterilization on the domestic dog population for the province of Teramo, Italy. Baseline owned dog population structure as well as the annual number of births, adoptions, abandonments, and purchases were estimated based on regional managed kennel data in addition to a telephone questionnaire administered to members of the local population. Age- and gender-dependent death rates were based on domestic dog life tables. The model predicts that at the current female dog sterilization rate of 30%, the owned dog population will most probably continue to increase. After 20 years, a mean annual increase of 2.6% (median: 2.5%, 95% CI: −3.2% to 8.8%) is projected assuming that the average age at sterilization is 3 years. A sterilization rate of at least 55% is estimated to be needed to halt population growth if the current age structure for female dog sterilization is maintained. However, if the province of Teramo were to focus on sterilizing female dogs less than 1 year of age, the required sterilization rate to arrest population growth could be reduced to as low as 26%. 相似文献

犬类呼吸道疾病是宠物犬常见病,严重者导致犬只死亡。但是,目前在临床上该病用药缺乏科学指导。本实验采集了西宁地区5家宠物医院共63例健康犬及92例呼吸道患病犬的标本,进行呼吸道多菌群的分离培养、染色镜检和全自动微生物分析仪鉴定,并对检出菌进行了Kirby-Bauer纸片扩散法药敏试验。结果发现,犬呼吸道正常菌群有缓慢葡萄球菌、放射根瘤菌、少动鞘氨醇单胞菌等;主要致病菌有金黄色葡萄球菌、肺炎克雷伯菌臭鼻亚种。通过对所有样品的菌株分离发现犬上呼吸道是以革兰阳性菌偏多,阳性菌株分离率(65.9%),阴性菌株分离率(34.1%)。药敏试验结果显示,革兰阳性细菌敏感的药物为头孢噻肟、头孢曲松,敏感率>50%。革兰阴性细菌敏感的药物为恩诺沙星、丁胺卡那,敏感率>70%。同时,两类菌群对阿莫西林、林可霉素都有明显的耐药性(耐药率>70%)。 相似文献

In some places of the northeastern Peruvian Amazon the harvesting and local trade of parrot nestlings is still a common practice (loreada) that takes place every year between February and April, despite being banned by the national laws. Between 1996 and 1999, I monitored the use of these birds in 3890-ha of Mauritia flexuosa-palm swamps, located close to the village of Victoria (Loreto, Peru). Seven species of parrots were collected by local poachers in the study area, with Amazona amazonica (61.1% of the captures) and Ara ararauna (25.9%) the most commonly harvested. The total number of nestlings taken during the 4-year study period was 1718, ranging from 680 birds harvested in 1996 to 166 in 1998. The two methods used to collect nestlings, cutting down the nesting tree or opening a hole in the trunk to reach the nest cavity, are not sustainable because nest-trees become useless and the next generation is completely removed. The analyses of demographic data and annual harvest rates suggest that at least three species (Ara ararauna, Ara macao and Amazona amazonica) are being over-harvested and may be seriously threatened in the long term. 相似文献
