分别对辽宁省益康生物制品厂1998年生产的3批乳康生进行活芽孢计数,样品采用封闭自然连存。隔19个月后用同样的方法进行计数,利用前后两次计数的均数差和时间差计算出活芽孢的半衰期。为生产乳康生制定质量标准和有效期提供依据。

鸡白痢沙门氏菌病是目前养鸡业中常见的传染病,虽然能够用于预防鸡白痢沙门氏菌病的抗菌药物很多,但是由于鸡白痢沙门氏菌易产生抗药性,防治效果不理想。作为生态防治类药物乳康生应用于临床报告较少。

Infection with human papillomavirus(HPV) is the major cause of pre-invasive and invasive lesions of the urogenital tract, resulting in morbidity and mortality worldwide. HPV-related infection is responsible for most cases of cervical cancer, a leading cause of cancer death in women worldwide. Developed countries have screening programs in place to detect precancerous lesions at early stages; in resource-limited settings however, HPV related diseases are often identified in advanced stages. This is due to limitations in the availability and roll out of effective screening programs. The relatively recent availability of the HPV vaccine has provided a new public health opportunity to decrease the incidence of HPV-related disease. The high mortality rates seen in developing countries could be reduced through effective implementation of HPV vaccination programs. Large trials have proven the efficacy of bivalent, quadrivalent vaccine and most recently 9-valent vaccine. Uptake in vaccination remains low due to multiple barriers including lack of education, lack of access, and costs. New strategies are being assessed to increase access, increase knowledge and reduce costs that may result in feasible vaccination programs worldwide. The goal of this article is to review the effectiveness and safety of the current HPV vaccines available, vaccine delivery strategies, cost effectiveness, and efforts to improve the acceptability. A literature search was conducted through Pub Med using the terms "HPV vaccination, and safety, and males, and acceptability and strategies, and cost effectiveness,"focusing on articles published between 2006 and 2015. The most relevant and larger scale trials were evaluated for discussion. 展开更多

Zoonotic transmissions of emerging pathogens from wildlife to human have shaped the history of mankind. These events have also highlighted our poor understanding of microorganisms circulated in wild animals. Coronaviruses and astroviruses,which can be found from a wide range of mammals,were recently detected in bats. Strikingly,these bat viruses are genetically highly diverse and these interesting findings might help to better understand the evolution and ecology of these viruses. The discoveries of these novel bats viruses not only suggested that bats are important hosts for these virus families,but also reiterated the role of bats as a reservoir of viruses that might pose a zoonotic threat to human health. 展开更多
