Abstract

This work examined the reproductive phenology of the Sardinian warbler (Sylvia melanocephala melanocephala) in North-eastern Algeria, which is its main geographical nesting area. Twenty-eight (28) nests were studied during two successive seasons (2016 and 2017). The results obtained in this study confirm that the nests were constructed at an average height of (01.97±01.04 m) from the ground. The laying period lasted eight (08) weeks (midMarch to the beginning of the second week of May), so fifty-four (54) days. The mean clutch size is (4.14±0.97) eggs per brood. The recorder traits were previously observed in European populations. The average of hatching success was (47.38 %) and mean reproductive success (45.24 %) were relatively low compared to European populations.

Abstract

Development of novel antimicrobials capable of providing long-lasting disinfection on surfaces requires the implementation of new standardized methods to support claims recognized by regulatory authorities. Surrogates for viral pathogens are often desired in order for BSL-2 labs to conduct these new efficacy tests safely and efficiently, however, the knowledge of surrogate suitability for these tests is limited. Here, for the first time, we determine the resistance profile of the bacteriophage Phi6 to quaternary ammonium compounds (QACs) in a variety of test conditions. Additionally, we show that Phi6 can be used to demonstrate the long-lasting virucidal efficacy of a novel antimicrobial, Actizone™ F5, and that the Phi6 is more resistant to QACs following the UK standard long-lasting disinfection test BSI PAS2424:2014 than Vaccinia virus, which is the marker strain for claims of activity against enveloped viruses in Europe. Surface stability as well as benefits and limitations of Phi6 use relative to other enveloped viruses for antimicrobial testing is also discussed.
