MDCK-Adaptive Mutation of A169S Changes Glycosylation Pattern of Hemagglutinin and Enhances MDCK-Based H7N9 Vaccine Virus Production without Loss of Antigenicity and Immunogenicity [PDF]
The adaptation of egg-derived H7N9 candidate vaccine virus (CVV) in the mammalian cell line is an approach to developing a high-growth virus strain for the mass production of vaccine manufacturing.

Seasonal Influenza H3N2 virus poses a great threat to public health, but its vaccine efficacy remains suboptimal. One critical step in influenza vaccine production is the viral passage in embryonated eggs. Recently, the strength of egg passage adaptation

آنالیز توالی ژن S1 سویه های واکسینال برونشیت عفونی طیور(H120 & H52) و ارزیابی تاثیر پاساژهای متوالی در تخم مرغ جنین دار بر آنها [PDF]
بیماری برونشیت عفونی طیور(IB) یکی از بیماریهای حاد و بشدت واگیردار طیور است که عمدتاً موجب ابتلاء دستگاه تنفس میشود. وجود تعداد زیاد سویهها و سروتیپهای ویروس عامل بیماری که قادر به ایجاد ایمنیت متقاطع بر علیه یکدیگر نیستند مهمترین مانع کسب نتایج ...

Low 2012-13 influenza vaccine effectiveness associated with mutation in the egg-adapted H3N2 vaccine strain not antigenic drift in circulating viruses. [PDF]
Influenza vaccine effectiveness (VE) is generally interpreted in the context of vaccine match/mismatch to circulating strains with evolutionary drift in the latter invoked to explain reduced protection.

Predicting Egg Passage Adaptations to Design Better Vaccines for the H3N2 Influenza Virus [PDF]
Seasonal H3N2 influenza evolves rapidly, leading to an extremely poor vaccine efficacy. Substitutions employed during vaccine production using embryonated eggs (i.e., egg passage adaptation) contribute to the poor vaccine efficacy (VE), but the evolutionary mechanism remains elusive. Using an unprecedented number of hemagglutinin sequences (n = 89,853),

Passage of Meloidogyne Eggs in Human Stool: Forgotten, but Not Gone [PDF]
Recently, we were involved in a project to train staff from the Atoifi Adventist Hospital (AAH) in East Kwaio, Malaita, Solomon Islands, in applied research and laboratory methods. The project, run by AAH, included the performance of a cross-sectional survey for soil-transmitted helminths in ...
