3). This demonstrates that this assay is an effective and robust method to confirm the identity

of a BCG sub-strain. The establishment of WHO Reference Reagent of BCG vaccine of Moreau-RJ sub-strain was approved by WHO ECBS in October 2012 with a content of 6.51 million CFU or 24.69 ng ATP per ampoule. This Reagent (NIBSC code: 10/272) is available and distributed by NIBSC-MHRA, UK. All the Reference Reagents of BCG vaccine are stored in a −20 °C facility with a trend monitoring system. The real-time stability of these Reference Reagents is monitored annually to ensure the viability of the content is within an acceptable range. The data collected in the first few years demonstrated that these Reference Reagents of BCG vaccine are very stable when stored at −20 °C. The intended uses of these Reference Reagents Crizotinib cell line are as comparators (1) for viability assays (such as cultural viable count and modified ATP assays); (2) for in vivo assays (such as the absence of virulent mycobacteria, dermal reactivity and protection assays) in the evaluation of candidate TB vaccines in non-clinical models; (3) for identity assays using molecular biology techniques. Special thanks are due to Fundação Ataulpho de Paiva for preparing and donating of ampoule-filled lyophilized BMS-777607 manufacturer preparation

of BCG vaccine for the establishment of the WHO Reference Reagent for BCG vaccine of Moreau-RJ sub-strain. Fundação Ataulpho de Paiva was supported by funds of Decit/SCTIE/MS-MCT-CNPq-FNDCT-CAPES to Brazilian

National Institute of Science and Technology for on Tuberculosis (INCT-TB) and would like to acknowledge financial support awarded by FAPERJ (Grant E-26/190.025/2011). “
“Respiratory syncytial virus (RSV) is the leading cause of severe lower respiratory tract disease in infants and young children worldwide [1] and is an important pathogen in elderly and high risk adults [2]. The World Health Organization (WHO) has estimated that the global annual burden of infections and mortality due to human RSV are 64 million and 160,000, respectively [3]. In industrialized countries, nearly all children have been infected with RSV by 2 years of age [4]. Most infected children present with mild upper respiratory tract symptoms, but a subset develops severe lower respiratory tract disease characterized by tachypnea, hyperinflation, crackles, and expiratory wheezing (i.e., bronchiolitis and pneumonia). The most severe disease occurs within the first months of life in largely full term, healthy infants. Data from the United States (US) and Australia suggest that 1.7–2.6% of infants are hospitalized for RSV infection before one year of age [5], [6] and [7]. In the US, approximately 75,000–100,000 infants less than 1 year of age [8] and [9] and 132,000–172,000 children less than 5 years of age [10] are hospitalized due to RSV disease annually.
