Re: Request for contributions: Helminth egg analysis methodologies (Determining helminth egg quantities (measurement techniques))
Hey, Richard et al.
Please find more details about our study of pathogen degradation in alternating dual-pit latrines at the first link below and about the Mini-FLOTACT method of enumerating viable (i.e., pathogenic) Ascaris ova at the second link below. I'd be happy to chat anytime about our study or methods.

Dear Elizabeth
Thank you for the follow-up on the progress of the study. Yes! I did read the thread on the forum and got some ideas. The thesis was done with some good insights that need further testing in the field, I would say, however, it is not yet ready for sharing but I promise I will share as soon as the embargo period is over in January 2022.
Warm regards,
Richard

Re: Request for contributions: Helminth egg analysis methodologies
Hi Richard,
Good luck with your research. Please keep us informed how you get on and what you find.
I am wondering if you have already browsed the threads in this sub-category:
Determining helminth egg quantities (measurement techniques)
If not, then you might find some useful pointers and connections there. (If you've already been there, you can just ignore my post.)
It's an important research field and I see quite a few people trying to come up with better or more standardised methods.
This one was a big project, I am wondering if there are any updates for it:
Developing a uniform Soil-transmitted helminth (STH) analysis consortium for analyzing fecal waste samples (DUT, South Africa) - helminth egg measurements
I think they had a follow-on project from that one but can't remember them posting about it on the forum.
Regards,
Elisabeth

Re: Request for contributions: Helminth egg analysis methodologies
Thank you very much for the reply. The research aims to identify quantitative helminths eggs testing methodologies suitable for the field (resource-constrained settings), specifically environmental samples in remote areas and humanitarian contexts (e.g. refugee camps). From the list of existing methodologies, a centrifuge seems to be key equipment, which might not always be available or used in the field. Firstly, my research, therefore, seeks to gather information and identify methodologies being used in the field whether modifications or pure. Secondly, I need to gather information on the expected key performance characteristic of a methodology to improve the accuracy and reliability of results for proper risk assessment before faecal sludge disposal or reuse. Finally, I would like to try and develop a decision making guide when choosing a methodology to use in the field under specific analysis objectives and conditions like availability of resources.
I believe some methods even the clinical ones like Mini-FLOTAC needs tweaking a bit to analyze environmental samples though not accurately but better than nothing.
For now, I would prefer that members complete the key informant's questionnaire and is not restricted to parasitologist only but anyone with experience or interest working with any helminths testing methodology.
@James I would be very happy to hear more about your project in Cambodia.
Thank you and my apology for the late reply

Hey, Richard.
Thanks for your post. I am PI for a study of the effectiveness of alternating dual-pit latrines in Cambodia, and we plan to measure viable helminth ova in fresh fecal sludge samples using the Mini-FLOTAC method. I'm interested to hear more about your research, as Paresh above is. Please tell us more, and if you'd like to be updated on our study in Cambodia, let me know. I'll also be filling out your survey this week; so, expect that soon. Have a great rest of your day!
Cheers,

Re: Request for contributions: Helminth egg analysis methodologies
Dear Richard,
Welcome to the forum.
That is an interestingly relevant area of work and I hope you get many responses. It would be helpful if you could tell us more about your research and about potential respondents to your two questionnaires. The latter will help respondents choose which form they should use.
regards
paresh

Request for contributions: Helminth egg analysis methodologies
Greetings
Am an MSc student at IHE-Institute for water education, currently carryout out research on "helminths eggs analysis methodologies with special focus on those used for testing environmental samples like compost manure, fecal sludge, and the soils. Attached are the two questionnaires that willing members can complete; one for key informants and the other for general professionals. One makes a choice on the tool complete. Please assist disseminate within the forum or you can provide a contact for specific individuals or organizations.
Sincerely
Richard Mwembe
