Research of Roman chamber pots show unusual infections

[guy]

 

Researchers have determined that ancient Romans suffered from various infections after studying the residue of ancient Roman chamber pots along the lower Danube in modern-day Bulgaria. Along with tapeworm eggs, the researchers found evidence of Entamoeba histolytica and Cryptosporidium.

The pots date from the 2nd and 4th centuries AD. The finding of Cryptosporidium is among the earliest in Europe.

Cryptosporidium is unusual in the Roman chamber-pot findings because protozoan parasites (like Cryptosporidium and Entamoeba) almost never survive in archaeological contexts, and Cryptosporidium oocysts are especially tiny, fragile, and easily destroyed. Finding them at all is extremely rare in paleoparasitology.

 

Cryptosporidium is unusual in the Roman chamber-pot findings because:

• Its oocysts are too small for standard recovery methods
• They rarely preserve in archaeological sediments
• European sites almost always test negative
• Protozoan paleoparasitology is far less successful than helminth detection
• Any confirmed detection would be one of the rarest protozoan finds in Roman archaeology

 

Cryptosporidium oocysts:

• are shed in low numbers compared to helminths
• are susceptible to desiccation, pH changes, and mineralization
• lack the thick chitinous shells that protect helminth eggs for millennia

 

Helminth eggs (whipworm, roundworm, tapeworm) have thick, durable shells and survive thousands of years.

Protozoa like Cryptosporidium have thin-walled, delicate oocysts that:

• degrade rapidly in soil
• are chemically unstable
• are easily mistaken for fungal spores or debris
• lack distinctive morphology under light microscopy

This is why the paleoparasitological record of Cryptosporidium is described as "elusive" and extremely sparse.

Have there been any written ancient records in regards to treatment of these conditions?  

Tapeworm - ugh.  I have two outside cats that I treat regularly for tapeworm, as they are mousers and hunters of other small creatures. And consumers of them.  I can't imagine having this ailment, so disgusting.

Classic Vaudeville routine:  Patron ordering at a restaurant-- "I'll have a piece of burnt toast and a rotten egg...I've got a tapeworm and that's good enough for him."

Worms, Giardia, Cryptosporidium and many others were common infections among humans everywhere prior to the advent of flush toilets. While Pliny alludes to the concept of contagious diseases spread by bad air (mal' aria) and foul water, without the benefit of the microscope, the ancients couldn't possibly know that the agents of infectious disease were microbes.

The study posted above is not amazing in that these diseases were present, but that they have actually been documented for the technical reasons outlined. Absence of proof is not proof of absence. Now we have the proof.

Latin for chamber pot is matella, and the word appears in several of the graffiti in Pompeii.
