Tree squirrels (Sciurus spp.) have exhibited high seroprevalence rates, suggesting that they are commonly exposed to West Nile virus (WNV). Many characteristics of WNV infections in tree squirrels, such as the durations and levels of viremia, remain unknown. To better understand WNV infections in fox squirrels (S. niger), we subcutaneously inoculated fourteen fox squirrels with WNV. Peak viremi...

In Belgium, the incorporation of phages into magistral preparations for human application has been permitted since 2018. The stability such is high importance to guarantee quality and efficacy throughout treatments. We evaluated ability preserve infectivity four different active against three bacterial species in five buffer infusion solutions commonly used medicine biotechnological manufacturi...

Poly-γ-glutamic acid (γ-PGA) is a naturally occurring polymer, which due to its biodegradable, non-toxic and non-immunogenic properties has been used successfully in the food, medical and wastewater industries. A major hurdle in bacteriophage application is the inability of phage to persist for extended periods in the environment due to their susceptibility to environmental factors such as temp...

Correlation between infectivity and physical virus particles in human cyto-megalovirus. J. Bacteriol. 92:1555-1561. 1966.-Infectivity titers [measured as plaque-forming units (PFU)] and particle counts by the sedimentation pseudo-replication ...

CRISPR-Cas systems silence plasmids and viruses in prokaryotes. CRISPR-Cas effector complexes contain CRISPR RNAs (crRNAs) that include sequences captured from invaders and direct CRISPR-associated (Cas) proteins to destroy corresponding invader nucleic acids. Pyrococcus furiosus (Pfu) harbors three CRISPR-Cas immune systems: a Cst (Type I-G) system with an associated Cmr (Type III-B) module at...

OBJECTIVE To analyse pharmacist intervention (PI) resulting from the implementation of the Dáder Pharmacotherapeutic Follow-Up Program (PFU). DESIGN Descriptive study of the findings from the PFU program during the first year. SETTING Community pharmacists in area of the College of Pharmacists of the Province of Cordoba (Argentina). PARTICIPANTS A total of 202 patients were included in th...

A nucleic acid sequence-based amplification (NASBA) technique for the detection of hepatitis A virus (HAV) in foods was developed and compared to the traditional reverse transcription (RT)-PCR technique. Oligonucleotide primers targeting the VP1 and VP2 genes encoding the major HAV capsid proteins were used for the amplification of viral RNA in an isothermal process resulting in the accumulatio...
