[Histonet] Treponema tissue blocks

[Tony Henwood]

Hi John,

I'm still around (though now retired). Histopeeps? I suppose I have been called worse but my thick formalinised skin (or xylene addled brain, which assumes I had one in the first place) probably skips over the "Histopeeps". Anyway, I often marvel and I am truly appreciative of the value of Histonet to my professional life. Many posts have caused my (microtome) cogs turning.

I can communicate with thousands across the world in real time or wait 12 hours till everyone, not in our time zone, wakes up! Well Australia is a heck of a long way away.

Many seeds for my publications were sown by Histonet. The Histonet archives is a godsend. I am not sure whether Facebook or Instagram offers the same.

Anyway, I'm off to play golf.


Regards,

Dear Bob,
Good to see that you're still histonetting!  Until I saw your recent message I was contemplating abandoning the web site after reading and occasionally contributing for more than 30 years.
The current abundance of emails addressed to "histopeeps" is insulting, especially to professionally qualified technologists. Relia, whoever you are, give us all a break.
We need more correspondence of the kind we had in earlier decades, about the technology.
Hopefully you and I are not the only remaining elderly histonetters.
Others, young or old, please show yourselves.
Cheers,  John Kiernan

In reply to Ni Nie's request:

The best source of Treponema pallidum control tissue used to be necrotic
liver from necropsies of syphilitic stillbirths. These were only 25 years
in the past when I was a pathology resident in the 1960s. Possibly some of
this material is still around. As congenital syphilis returns, there might
be such material available today - one such case could supply the world for
years, after all.

Mycobacterium tuberculosis control tissue can be obtained from necropsies
on monkeys with tuberculosis, most commonly rhesus macaques in India.
