Antibiotics take toll on beneficial microbes in gut
... normal microbes after an untreated mouse was placed in the same cage. That wasn't a complete surprise, since mice have a habit of eating the feces
of their cage mates and therefore picked up normal gut microbes quickly.
Not a lesson applicable to humans? In patients with refractory ...
New tracking approach will help protect polar bears
... the meat are sent to Dr. Boag's lab, where the number and sex of the animals are determined using DNA markers. At the same time, samples of bear feces
are collected and genetically screened by collaborators at the Laboratory of Wildlife Diseases at the San Diego Zoo for the presence of ...
Diuscovery in amber reveals ancient biology of termites
... evolutionary scale the termites began producing a liquid that contained protozoa that they would excrete. The termite offspring in turn consume the feces
and thereby gain the protozoa in their digestive systems.
It took time for all of this to get worked out, the study indicated. The successful ...
Diabetics on high-fiber diets might need extra calcium, report UT Southwestern researchers
... digestive system, absorbing water and easing defecation. Calcium is a nutrient found in food that is absorbed by the body and then excreted in urine, feces
or sweat. It is the most abundant mineral in the human body.
Prior research at UT Southwestern has shown that a high intake of dietary fiber, ...
In many fungi, reproductive spores are remarkably aerodynamic
... of ascomycetes, the largest phylum of fungi. These fungi enter the sexual phase of their life cycle when they deplete nutrients in the deposits of feces
or decaying matter where they reside.
In these species, spores are held in fluid-filled sacs where pressure builds until they eventually explode, ...
Transporting broiler chickens could spread antibiotic-resistant organisms
... no effective barrier to prevent release of pathogens into the environment. Previous studies have reported that these crates become contaminated with feces
The new study was conducted on the Delmarva Peninsulaa coastal region shared by Maryland, Delaware and Virginia, which has one of ...
Rapid test for pathogens developed by K-State researchers
... apart from another and determine antibiotic resistance.
Traditionally, it takes days and multiple lab workers to screen a sample of soil, water or feces
for just one pathogen. Additional time is then needed to look for resistance to antibiotics. The new test developed at K-State simultaneously looks ...
Novel fungus helps beetles to digest hard wood

Primate's scent speaks volumes about who he is
... different scents. Other lemur species also have glands on their heads, chests and hands. Add to these scents the signals that can be conveyed in feces
and urine, and there's a lot of silent, cryptic communication going on in lemur society.

Indiana U scientists uncover potential key to better drugs to fight toxoplasmosis parasite
... animals and birds, but it reproduces in cats, which can shed the parasite in their feces. Humans can be infected through contact with the infected feces
or litter. People can also become infected by consuming undercooked meat.
A vaccine to prevent infection in cats and livestock could prevent a ...
Fecal microorganisms inhabit sandy beaches of Florida
... the shoreline water is affected by bacterial run-off from the sand.
This has implications for beach managers since the number of bacteria from feces
(fecal bacteria) in the water is used to assess the presence of sewages. A high count of these indicator bacteria would require the beach to be ...
Ant parasite turns host into ripe red berry, biologists discover
... the parasite's eggs more broadly, since the eggs pass directly through into the feces. Ants become infected when they feed to ant larvae the bird feces
containing parasite eggs. The nematodes hatch and migrate to the gaster of the ant pupae, where they mate. After the pupae become adults, the adults ...

Parasites' impact goes beyond host to affect ecosystem
... host. Shorebirds ?more prevalent on Appledore than on the mainland ?are the final hosts, contracting infection by eating infected fish, then in their feces
excreting the eggs of C. lingua, which are in turn eaten by the snails.
