The idea that they might be “spider droppings” shocked her. She posted in a Facebook group, “Does anyone have any idea what these spots might be?”.
The results are puzzling. Numerous studies claim that the antibacterial properties of various spider venoms – and their blood – could explain the observed absence of germs. These broad-spectrum antibacterial peptides have been shown to be effective against E. coli, staphylococcus species, enterococcus species, Pseudomonas species and other bacteria.
Melissa Gaver-Wainwright, a graduate student in entomology at Washington State University, conducted preliminary research to answer these questions.
To determine whether black widow (Latrodectus Hesperus) waste could transmit disease, she took a fecal sample in a sterile container and dipped it in a culture medium to increase the amount of bacteria in the sample.He then amplified a conserved section of the 16S rRNA gene using universal bacterial primers to determine fecal-bound microbes. No pathogens were detected in the spider droppings.
Many questions remain to be answered.
