Infectious parasitic #roundworm found in #raccoon feces is rare, seen in only two dozen documented cases over several decades, but recently has infected two people in #LosAngeles with the dangerously deadly and oft #neuro damaging effects.Those who do survive infection are often left with severe neurological outcomes, including blindness, paralysis, loss of coordination, seizures and cognitive impairments.

The #CDC suggests #fire may be best , perhaps only way, to fully fight this particularly potent #plague.

Human cases of raccoon parasite may be your best excuse to buy a flamethrower

The infection is very rare, but it’s definitely one you want to avoid.

Roundworm study reveals essential genes for sperm and egg cell formation

The common roundworm has helped Monash University researchers unlock new information about fertility and genes. Professor Roger Pocock of Monash University's Biomedicine Discovery Institute has led a team which has found new and very specific genes, in the worms, which help grow 'germ' cells, or germination cells. These, depending on specific genes, become either sperm cells or egg cells.

I've been thinking about organic gardening, #infectious #parasites and their effect on gardeners, catching up on research I noticed re #diseases in ancient Egyptian civilisations.

Given that as society breaks down we are going turn more and more more to #human waste spread on land both as means of disposal and enrichment, what can do to protect ourselves from intestinal and skin parasites? (#Roundworm, #tapeworm etc)

I know we already use composting toilets etc, but this relies on #composting human waste for around a year (or more) and maybe there will be a need to speed up (ot shortcut) the process as "normal" society collapses.

So, what are the bare minimum requirements of a "safe" process, and are there any home remedies (#herbal brews, #salves and #potions) that have been used to treat these #infections in the past?

Pet Poop Can Be Much More Dangerous Than You Might Realize

Have you ever been out on a walk and as you take that next step, you feel the slippery squish of poop under your foot? It's not just gross.

First molecular data on the human roundworm Ascaris lumbricoides species complex from the Bronze and Iron Age in Hallstatt, Austria - Scientific Reports

Palaeoparasitological studies can provide valuable information on the emergence, distribution, and elimination of parasites during a particular time in the past. In the prehistoric salt mines of Hallstatt, located in the Austrian Alps, human faeces have been conserved in salt. The aim of this study was to recover ancient DNA of intestinal parasites from these coprolites. Altogether, 35 coprolites from the Hallstatt salt mines, dating back to the Bronze Age mining phase (1158–1063 BCE) and the Iron Age mining phase (750–662 BCE), respectively, were analysed by microscopy and molecular methods. In 91% of the coprolite samples, eggs of soil-transmitted helminths (STH), namely of Trichuris and/or Ascaris were detected by light microscopy. The Ascaris eggs were exceptionally well preserved. For further analysis, DNA was extracted from the palaeofaecal samples and species-specific primers targeting different genes were designed. While amplification of Trichuris DNA remained unsuccessful, sequence data of A. lumbricoides species complex were successfully obtained from 16 coprolites from three different genes, the mitochondrial cytochrome c oxidase subunit 1 gene (cox1), the mitochondrial cytochrome B gene (cytB) and the mitochondrial NADH dehydrogenase subunit 1 gene (nadh1). Importantly, these included two Ascaris sequences from a coprolite from the Bronze Age, which to the best of our knowledge are the first molecular data of this genus from this period.

Living roundworm pulled from brain of patient, suspected to have come from python poo

In a world first, doctors have extracted a living roundworm usually found in carpet pythons, from a patient's brain. They believe the infection occurred after the patient ate contaminated native greens.

"Scientists woke up a 46,000-year-old roundworm from Siberian permafrost

A female microscopic roundworm that spent the last 46,000 years in suspended animation deep in the Siberian permafrost was revived and started having babies in a laboratory dish."
