“Much of the fortress was left in ruins, never to be rebuilt, but the latrines on its lower floors survived…Cambridge researchers Evilena Anastasiou and Piers Mitchell, who study ancient parasites, collected samples from one of those cesspools, rehydrated the waste and strained it through a micro-sieve to catch parasite eggs, each smaller than a tenth of a millimeter.”

Stomach ache
By J. Russell Stothard, Liverpool School of Tropical Medicine
On the left are Schistosoma bovis collected from the gut mesenteries of an African cow, and on the right are paramphistomes (stomach flukes of ruminants that mainly affect cattle and sheep) collected from the stomach of the same cow. S. bovis typically causes low mortality but continuous poor health and poor productivity of a herd. Only the immature paramphistomes (flukes) cause disease and mortality, whereas the adult flukes do not cause obvious disease.

New research has revealed there may be some truth behind the garlic repels vampire myth. A scientist from James Cook University has found that fish fed garlic-enriched diets have less chance of being infected by fanged Neobenedenia sp. parasites than fish that don’t eat garlic. The parasites cost fish farmers heavily in lost animals each year.Find out more about studying at JCU (you can even study aquaculture): http://bit.ly/1aDe21Rand read the full story here: http://bit.ly/19ndOrP

Parasitic Complexity (Wired)

For decades, parasites were viewed primarily as pests: something to ignore, perhaps with a sniff of disgust, unless they harmed humans, in which case they were enemies. In recent years, though, scientists have come to appreciate the nuanced, often important roles played by parasites in animal life.
Much of that appreciation involves the relationship between parasites and immune system function, but there’s an ecological angle, too. Witness this computer-modeled food web: When parasites are included in its parameters, it’s revealed as a far more complex system than it appeared without them.

Homosexuality in microscopic parasites

bogleech:

Schistosomes or “blood flukes” are microscopic parasites who live out their adult lives in permanent mated pairs.

Usually, the thread-like female lives in a groove along the male’s boat-like body.

Sometimes, however, two males will pair up. One takes on the female role, staying smaller…

Richard III’s remains riddled with roundworms
NBC News: New analysis of the Richard III’s remains indicate that the king had a clear case of intestinal parasites. A team of researchers  found the eggs of Ascaris lumbricoides, a roundworm, in a sample taken from Richard III’s remains. Roundworm eggs were not found at other locations on the site where Richard III’s remains were found, suggesting the worms were buried with the king.

Added a few more pendants to the old Etsy! Lots of ferns this week; Dryopteris intermedia, being an evergreen fern, is one of those few winter plants I still have access to.

As always, thank you for reblogging! It helps more than you know.
