The aim of this work was to determine the recovery rate of feline calicivirus (FCV-F9) infectious particles and genome from water after a concentration step using either adsorption elution on glass wool or filtration through an electropositive membrane. The results showed that the membrane filtration technique allowed a 75% recovery rate of FCV-F9 infectious particles while the yield was only 5.3% for FCV-F9 genome. Using the glass wool adsorption-elution technique, the recovery rate of FCV-F9 infectious particles was 0.5% while the yield was 102.5% with Poliovirus 1.

Background: Monitoring the efficacy of the sterile insect technique (SIT) programs, it is desirable to discriminate between wild and sterile tsetse males captured in monitoring traps. Currently, this is primarily achieved by marking sterile males with fluorescent dye powder before release, and identifying them using a fluorescence camera and/or microscope. However, the accuracy of this method is limited due to defective marking and wild flies contaminated with a few dye particles in the monitoring traps.

Background: Tuberculosis is one of the leading causes of death from infectious diseases in the world, with approximately 25% of the global population having latent tuberculosis infection. Secondhand smoke exposure has been recognised as a significant risk factor in the development of active Tuberculosis in individuals with latent tuberculosis infection.
Study Design And Methods: This study used the Systematic Literature Review method based on PRISMA guidelines.
Mycobacteriophages are viruses that specifically infect bacteria of the Mycobacterium genus. A substantial collection of mycobacteriophages has been isolated and characterized, offering valuable insights into their diversity and evolution. This collection also holds significant potential for therapeutic applications, particularly as an alternative to antibiotics in combating drug-resistant bacterial strains.

Oncolytic adenoviral therapy is a promising approach for pancreatic cancer treatment. However, the limited capacity of murine cells to produce infectious viral progeny precludes the full evaluation of the virotherapy in a suitable immunocompetent mouse model. Here, we report that the murine KPC-I cell line, established from pancreatic tumors developed in ; ; mice, is susceptible to adenoviral replication and generates a progeny of infective virions similar to those from infected human A549 cells.
