在哈尔滨地区采用群体采样法分别从6个区218个鸡场采集新鲜粪样,经饱和盐水漂浮法检查,有136个鸡场感染艾美球虫,感染率为62.39%,表明哈尔滨地区鸡球虫感染现象比较普遍.经临床症状及卵囊形态观察,共检出6种艾美球虫,分另q是柔嫩艾美球虫、堆形艾美球虫、毒害艾美球虫、早熟艾美球虫、和缓艾美球虫与巨型艾美球虫,其中柔嫩艾美球虫为哈尔滨地区鸡球虫病病原的优势虫种.  相似文献

Respiratory pathogens have been detected in forensic investigations using multiple techniques; however, no study has examined the use of automated, nested, multiplex polymerase chain reaction (ANM‐PCR), commonly used in living patients, in the forensic setting. This retrospective study assessed the utility of ANM‐PCR in detecting respiratory pathogens in the pediatric forensic setting. Respiratory samples from 35 cases were tested for up to 20 respiratory pathogens. 51.4% of these cases yielded a positive ANM‐PCR result, 20% of which were considered the cause of or contributory to death. The most commonly detected pathogens were rhinovirus/enterovirus and respiratory syncytial virus, and these were the only pathogens determined to play a significant role in cause of death. The sampled sites and postmortem intervals tested did not affect the likelihood of a positive or negative test. ANM‐PCR panels are effective, affordable, and rapid ancillary tools in evaluating cause of death in the forensic pediatric population.  相似文献

利用人回盲肠癌(HCT-8)细胞作为感染细胞,采用不同的接种细胞浓度和培养血清浓度进行培养,观察细胞的生长状况;在培养细胞中加入1×105个经活力检测的微小隐孢子虫卵囊,培养72h后用荧光标记的隐孢子虫卵囊、子孢子染色试剂盒Crypt-a-Glo和Sporo-Glo进行染色,观察不同发育阶段的隐孢子虫形态。结果显示,在六孔培养板中接种10×105个细胞后,24h后长成80%~100%单细胞层,可以用来接种微小隐孢子虫。培养72h后观察到了隐孢子虫各个阶段虫体的形态。结果表明,成功建立了微小隐孢子虫感染HCT-8细胞模型。  相似文献

Sudden fatal cases of influenza B infection in a 4-year-old girl and a 2-year-old boy are presented. Both children complained of abdominal pain without respiratory, neurologic or cardiac symptoms; additionally the girl had vomiting within 2 days of death. Autopsy revealed histological changes in the respiratory system consistent with a viral infection. Influenza B infection was identified by immunohistochemistry in the girl and real-time polymerase chain reaction in the boy. Additional testing including cultures, toxicology, and screening for metabolic disorders were negative. These cases illustrate the usefulness of viral testing, especially for influenza, in the medical legal autopsy of children even when the classic respiratory symptoms of flu are lacking.  相似文献

SUMMARY

During National Collegiate Alcohol Awareness Weeks of 1992, 1994, and 1995, blood alcohol concentration (BAC) feedback was offered to pedestrians. Two BAC feedback stations were set up near bars frequented by many university students, and were staffed for either two or three consecutive nights. These stations provided passers-by with their. BAC, as determined by portable breathalyzers. Across the three years of the study, a total of 1,590 individuals (1,192 men, 398 women) participated. The mean BAC for all participants was 0.063 (S.D. = 0,039), ranging from 0.0 to 0.310. Data analysis revealed a main effect for BAC across days, with average BAC being significantly greater on Thursdays than Fridays. A main effect was also found for time, with BACs becoming higher as the night progressed. No main effect for gender was found. However, a significant gender by day of the week interaction resulted from female BAC levels being higher than those of males on Thursdays but male BAC levels being higher than those of females on Fridays. Implications of findings for intervention efforts aimed at curtailing DUI and other alcohol-related problems are discussed.  相似文献
