Calibration of the 7th British Working Standard for factors II, IX and X, concentrate
Publication date: Available online 24 August 2018Source: BiologicalsAuthor(s): Graham Roberts, Helen Wilmot, Thomas Dougall, Peter Rigsby, Elaine GrayAbstractSeven laboratories from 5 different countries participated in the calibration of the 7th British Working Standard (BWS) for blood coagulation factors II, IX and X. The candidate, 15/182, was assayed for Factors II and X potencies against the 4th International Standard (IS) for Factors II and X, Concentrate (11/126) and for Factor IX potency against the 5th IS for Factor IX, Concentrate (14/148). Intra-laboratory GCVs for all 3 factors were less than 10%, with the majo...

Re-evaluating the LD50 requirements in the codified potency testing of veterinary vaccines containing Leptospira (L.) serogroup Icterohaemorrhagiae and L. serogroup Canicola in the United States
Publication date: Available online 17 August 2018Source: BiologicalsAuthor(s): Angela Walker, Renee Olsen, Mindy Toth, Geetha SrinivasAbstractApproximately one-third of the reportable USDA Category D and E laboratory animals in the United States are expended on the potency testing of leptospiral vaccines by the codified hamster vaccination-challenge assay. Valid tests require ≥80% of challenge controls to succumb to disease and an LD50 between 10 and 10,000. This work evaluates the risk associated with the removal of LD50 limits; thereby, eliminating back-titration hamsters from in vivo potency assays for Leptospira (L.)...

Report of the international conference on next generation sequencing for adventitious virus detection in biologicals
Publication date: Available online 6 August 2018Source: BiologicalsAuthor(s): Arifa S. Khan, Luca Benetti, Johannes Blumel, Dieter Deforce, William M. Egan, Ivana Knezevic, Philip R. Krause, Laurent Mallet, Dietmar Mayer, Philip D. Minor, Pieter Neels, Guanhua WangAbstractA fundamental aspect of biological product safety is to assure absence of adventitious agents in the final product. Next-generation or high-throughput sequencing (NGS/HTS) has recently demonstrated detection of viruses that were previously missed using the recommended routine assays for adventitious agent testing of biological products. This meeting was c...

Proteome-wide identification of epitope-based vaccine candidates against multi-drug resistant Proteus mirabilis
Publication date: Available online 2 August 2018Source: BiologicalsAuthor(s): Nosheen Ehsan, Sajjad Ahmad, Syed Sikander Azam, Thanyada Rungrotmongkol, Reaz UddinAbstractProteus mirabilis is one of the important pathogens of urinary tract and exhibits resistance to multiple drugs. Development of vaccine tends to be the most promising and cost-effective remedy against the said pathogen. Herein, we implement a combinatorial approach for screening proteins harboring potential broad-spectrum antigenic epitopes in the proteome of P. mirabilis. The targets are host non-homologous, essential and virulent, and have localization in...

Baculovirus expression and purification of peste-des-petits-ruminants virus nucleocapsid protein and its application in diagnostic assay
Publication date: Available online 17 July 2018Source: BiologicalsAuthor(s): Suresh H. Basagoudanavar, Madhusudan Hosamani, D. Muthuchelvan, R.P. Singh, R. Santhamani, B.P. Sreenivasa, P. Saravanan, A.B. Pandey, R.K. Singh, Ramamurthy VenkataramananAbstractPeste-des-petits-ruminants (PPR) is a contagious and highly devastating disease of small ruminants. For control of endemic PPR, adequate supply of affordable and reliable diagnostics is critical for effective surveillance, along with the use of highly efficacious live vaccines that are currently available. The nucleocapsid (N) protein of PPR virus (PPRV) is an important ...

Ishii, Kentaro Tanemura, Takuo Mizukami, Isao HamaguchiAbstractRecently, many vaccine adjuvants have been developed; however, most of the newly developed adjuvants have been dropped out of preclinical and clinical trials owing to their unexpected toxicity. Thus, the development of highly quantitative and comparable screening methods for evaluating adjuvant safety is needed. In a previous study, we identified specific biomark...

Human challenge trials in vaccine development, Rockville, MD, USA, September 28–30, 2017
The objective of this meeting was to examine the use of HCT, in response to the continuing human suffering caused by infectious diseases, preventable by the development of new and improved vaccines. For this, the approach of HCT could be valuable, as HCT can provide key safety, tolerability, immunogenicity, and efficacy data, and can be used to study host-pathogen biology. HCT can generate these data with speed, efficiency and minimal expense, albeit not with the same level of robustness as clinical trials. Incorporated wisely into a clinical development plan, HCT can support optimization or down-selection of new vaccine c...

Identification of T cell and B cell epitopes against Indian HCV-genotype-3a for vaccine development- An in silico analysis
Publication date: May 2018Source: Biologicals, Volume 53Author(s): Varun Chauhan, Mini P. Singh, Radha K. RathoAbstractHepatitis C virus (HCV) infects almost 150 million people and is a leading cause of liver disease worldwide. It has been classified into seven genotypes; the most common genotype affecting Indian population is genotype 3 (60–70%). Currently there is no vaccine for any genotype of HCV. In order to develop peptide based vaccine against HCV, it is important to identify the conservancy in the circulating genotypes, along with the Human Leucocyte Antigen (HLA) alleles in the target population. The present stu...
