Virus Could Behave Like a 'Late-life-acting' Biopesticide Against Malaria
Analysis following infection showed that although AgDNV levels increased modestly during larval development they still replicated slower resulting in significantly decreased virus levels during this stage.
Additionally, virus levels greatly increased in 7-to-10-day-old adults.
"Ultimately, we expect that a properly engineered LLAI AgDNV can be deployed in the field to significantly modulate malaria transmission," said the researchers.
A prior study showed that H5N1 could replicate in the skin cells of feathers and further suggested that those that drop off the body could potentially contaminate the environment.
Here, researchers evaluated the environmental risk posed by contaminated feathers by inoculating domestic ducks with H5N1, collecting feathers, feces and drinking water three days following, and then storing them at 39 degrees and 68 degrees Fahrenheit for 360 days.
Results showed that H5N1 persisted the longest in feathers at both temperatures.
"These results indicate that feathers detached from domestic ducks infected with highly pathogenic avian influenza virus (H5N1) can be a source of environmental contamination and may function as fomites with high viral loads in the environment," said the researchers.
The study has been published in the latest issue of the Journal of Virology.
