Sero-Prevalence and Associated Factors of Hepatitis B Virus Infection among Health Professionals in Adama Town, Oromia, Central Ethiopia
Hepatitis B is an infectious disease that caused by hepatitis B virus infection. Hepatitis B virus replicates in the liver and causes both acute and chronic hepatitis. The virus predominantly transmitted through a blood and sexual contact from potential sources. Healthcare professionals are at great risk of occupational exposure to this virus.
In assisted reproduction of cattle the design and preparation of in vitro culture media has been instrumental in supporting the development of bovine oocytes and embryos. In vitro production (IVP) involves three main sequential steps: oocyte aspiration and in vitro maturation (IVM); in vitro fertilization (IVF); and in vitro culture (IVC) of early pre-implantation embryos.
Requirements for Cryopreservation of In Vitro-Produced Bovine Embryos by a Standard Method of Vitrification
In relation to assisted mammalian reproduction, the goal of cryopreservation is to preserve without significant loss of viability a stock of gametes and/or embryos with a view to thawing those cells for use in in vitro reproduction treatments. There are numerous cryopreservation protocols, which vary in terms of cryoprotectant used, storage temperature, freezing and thawing rates, and the particular cells that they are suitable for preserving.
Streptococcus pneumoniae is a leading cause of meningitis. Although rates of bacterial meningitis have decreased after pneumococcal conjugate vaccine introduction, pneumococcal meningitis has not been eliminated. In this case series, we describe the presentation, serotypes, and outcomes of 11 children with pneumococcal meningitis at a tertiary children’s hospital after the 13-valent pneumococcal conjugate vaccine (PCV13) was introduced, from 2011-2013. The median age of children with meningitis was 7 years. The majority of the isolates (82%) were susceptible to penicillin. Most isolates (73%) were serotyped and there was no evidence of disease caused by serotypes contained in PCV7
