Suzanne writes (re Aphids):
The best way to get rid of aphids in the garden (the ants in my yard love to herd them onto my okra) is a sharp stream of water from the hose. Aphids wash right off! They don't tend to come back right away, either.
My research is focused on the biofilms formation, Motility (swarming and swiming ) and QS in fluorescent Pseudomonas (P. aeruginosa and P. fluorescens).
In laboratory a interaction had been with insect and bacteria metabo... Read More

In cells with latent HIV infection, the virus is dormant, and such cells are therefore not attacked by the immune system or by standard antiretroviral therapy. To eradicate the virus from the human body and truly cure a patient, reservoirs of latently infected cells need to be activated and elim... Read More
Just when we think we know everything, a story comes along to remind us that there is something fundamental--and seemingly elementary--that we still haven't figured out. “Why are we the size we are? Why are our organs the size they are? Why are the cells in those organs a stereotypical size? Wha... Read More

Shown here is a picture of a hookworm egg found on a concentrate in an ova & parasite exam
Human hookworms include the nematode species, Ancylostoma duodenale and Necator americanus. These species have indistinguishable eggs and can only be distinguished by their larvae.
Infective larvae g... Read More
Plant-like microorganisms called algae are pretty interesting little creatures - some species form expansive 'algal blooms' that harm the environment, whereas others can be used to produce biofuel and food sources. Some can even infect humans and mess with their brains.
This diverse organism ... Read More
Paenibacillus species have been isolated from a wide variety of sources including soil, water, the plant rhizosphere, plant materials, food, fodder, faeces and diseased insect larvae. They are facultative anaerobes or strict aerobes and mostly motile, endospore forming rods. This is the first ti... Read More

It's well known that antibiotics can disrupt our gut bacteria. But when mosquitoes snack on blood laced with antibiotics, the same can happen to their microbiome. And that depletion of gut bacteria actually increases mosquitoes' susceptibility to the malaria parasite. Meaning they may be more li... Read More
Washington, DC - July 30, 2015 - In research that could lead to protective probiotics to fight the “chytrid” fungus that has been decimating amphibian populations worldwide, Jenifer Walke, PhD, a postdoctoral researcher at Virginia Tech University, Blacksburg, and her collaborators have grown ba...

The TWiV gang reviews ten fascinating, compelling, and riveting virology stories from 2014.
Here's an Ebola puzzle for you: If the virus isn't airborne, why do doctors and nurses need to wear full protective suits, with face masks, while treating patients?
After we dug through studies and talked to scientists, the answer slowly emerged.
Ebola does spread through the air. But not ... Read More
Researchers have created a synthetic DNA analog that can bind to and silence the gene responsible for NDM-1, a severe form of antibiotic resistance that can make ... Read More
A permissive vaccine prevents disease in the immunized host, but does not block virus infection. Would a permissive vaccine lead to the emergence of more virulent viruses?
This hypothesis is based on the notion that viruses which kill their hosts too quickly are not efficiently transmitted, a... Read More
