A total of 520 clinical and environmental isolates of the family Micrococcaceae that fermented glucose anaerobically were tested for their ability to produce coagulase, thermostable nuclease, and deoxyribonuclease. Of these, 450 isolates coagulated rabbit plasma, produced thermostable nuclease, and were identified as Staphylococcus aureus, 447 of which produced a 3+ to 4+ clot. The remaining th...
the main objective of this study was to purify and characterize an esterase from shewanella sp f88. the enzyme was purified 41-fold and an overall yield of 21 %, using a two-step procedure, including ammonium sulfate precipitation and q-sepharore chromatography. molecular weight of the enzyme was 62.3 kda according to sds-page data. the enzyme showed an optimum activity at ph 6.5 and 58 ˚c. evo...
Background: A COVID 19 vaccine is a intended to provide acquired immunity against severe acute respiratory syndrome corona virus 2. Ad26.COV2.S (Johnson & Johnson) adenovirus vector-based that targets the spike protein of SARS-CoV-2 virus, when it enters body stimulates immune response. Materials and methods: This was cross sectional study, health facility base, Conducted in Vacci...
Although effective rabies virus vaccines have been existing for decades, each year, rabies virus infections still cause around 50.000 fatalities worldwide. Most of these cases occur in developing countries, where these vaccines are not available. The reasons for this are the prohibitive high costs of cell culture or egg grown rabies virus vaccines and the lack of a functional cold chain in many...
The need to increase the COVID-19 vaccine manufacturing capacity at low middle-income countries (LMIC) led a growing focus on Novavax (NVX-CoV2373), thermostable protein subunit manufactured using baculovirus and insect cell system (BICS) platform. This study aimed conduct techno-economic analysis assess BICS platform of compare it mRNA saRNA data from patent for formulation steps were used sim...
Polymorphic parasite antigens are known targets of protective immunity to malaria, but this antigenic variation poses challenges to vaccine development. A synthetic MSP-1 Block 2 construct, based on all polymorphic variants found in natural Plasmodium falciparum isolates has been designed, combined with the relatively conserved Block 1 sequence of MSP-1 and expressed in E.coli. The MSP-1 Hybrid...
Humoral immune response of vaccine-I (supermatent from sonicated sporulated oocyst), vaccine –II (sediment from sonicated sporulated oocyst) and vaccine –III (un-sonicated sporulated oocyst) against conccidiosis in chickens was determined by indirect haemagglutination (IHA) test. IHA antibody titre was significantly higher (p
Spray dried vaccine formulations might be an alternative to traditional lyophilized vaccines. Compared to lyophilization, spray drying is a fast and cheap process extensively used for drying biologicals. The current study provides an approach that utilizes Design of Experiments for spray drying process to stabilize whole inactivated influenza virus (WIV) vaccine. The approach included systemati...
