Hello, Mrsflib.
Welcome.
Re: Is this the rhrplus forum?
By definition, this is the M.D.'s Forum [as I call it], the "Ask Microbe Detectives Forum". However, since the Forum owners head RHR Plus, you can say they're 'linked' of course, yes.
Re:
"
I believe I have contracted several parasites when ingesting 'dirty' raw milk last November.
A question I have is, 'how long is the life cycle of most parasites?'
"
I think the best answer I can give you is "I don't know".
In order for anyone to answer that question with precision, ALL the parasites would have to be known by the person, and believe me, there are many. Most experts would agree that many details of most species remain unknown, I'm sure.
Take an insect known as the "Magicicada septendecim", by its scientific name, for example; this organism has been studied to have a parasitic life cycle of 5 years, but an entire life cycle of 17 years:
---------------------------------------------------------------------------------
"...Magicicada is the genus of the 13- and 17- year periodical cicadas of eastern North America. These insects display a unique combination of long life cycles, periodicity, and mass emergences. They sometimes go by the common name "seventeen-year locust"[citation needed], but they are not locusts; locusts belong to the order Orthoptera...."
(from
http://en.wikipedia.org/wiki/Magicicada
),
and:
"...The Magicicada septendecim, a most notable periodical cicada, has the longest life cycle of any insect. There are 3 species with 13-year life cycles and another 3 species with 17-year cycles. They are synchronized perfectly that they are nearly absent as adults in the 12 or 16 years between emergence...."

------------------------------------------------------------------------------------
How can we be sure there aren't any longer periods?
Many of the "common" worms that infect man have life cycles as long as months.
Also, there are worms that depend on a host to ingest their eggs in order for them to complete their life cycle. This could be a long time, being a fact that many parasite eggs remain viable for quite long. E. granulosus eggs [which infect man from dogs, by the way] can survive in the soil for YEARS. This next excerpt below mentions E. granulosus egg survival of "at least a year", but I ASSURE YOU that that statement, while truthful, perhaps, is very conservative:
--------------------------------------------------------------------------
"...The eggs can survive at least a year in the environment as they are highly resistant to environmental stress. The eggs are vulnerable to high temperatures and desiccation however, dying in two hours under these conditions. Egg survival time is increased in damp and cool (the eggs can survive freezing) conditions (for example near watering holes). Once passed in the feces the eggs can be transported by the wind, water, and insects (flies). Egg shedding in the definitive host may be cyclical and each worm can produce by sexual means up to 1000 eggs every 10 days for up to 2 years. Each egg contains an embryo or onchosphere that serves as the infective stage. When the eggs are voided from the canid definitive host they contaminate vegetation and are accidentally ingested by the cervid intermediate host. Humans can be infected by ingestion of eggs acquired from contaminated food or water, from handling live canids or pelts from dead canids, or by handling canid fecal material...."

And those are just quick examples. I've read authors suggesting decades, maybe hundreds of years, maybe more [I'm not sure of the scientific worthiness of this last comment, but just so you have an idea]. Personally, sometimes I suspect even worse.
"
My symptoms are chronic...about every two weeks. I tend to have one week between flareups of good health. Is this systematic of parasites?
"
Can be, in my opinion, but I wouldn't go around believing that it is just yet. I'd need proof first. Evidence.
"
How does the lab work? I mean do I bring in stool samples to my doctor to send to your lab?
"
Nah, this is very personal between you and RHR Plus. You're running your own show, no middlemen. You send the samples, you get the results, no one else.
"
Is this in conjunction with my local hospital lab?
"
This is in conjunction with no one, as far as I'm concerned. It's all between you and RHR, no one else. After you get your results, however, it's up to you. You may wish to take those results along to your doctor or to anyone else that could help you, for example; or, if you fear a diagnosis of "delusional parasitosis" with an unasked prescription of antidepressants and related drugs [as it's happened so many times before], you could keep them in record as part of your medical history. I would say that such kinds of records are VERY useful for an entire family, because many of these infections/infestations are contagious and could play a part in an entire family's future. I've seen it happen many times before.
"
What about blood samples? I can't obtain those myself...unless you use a pin prick on my finger!
"
For precision, I would prefer to have those sorts of questions answered to you directly [email] by DD or through the website's FAQ, but blood samples aren't that hard to obtain.
"
Do you send me actual pics of the varmins?
"
Sure. Pictures are sent to you of whatever is found that looks 'suspicious'.
"
I truly wish I had a scientific mind to understand these things.
"
In my opinion, it depends how far deep you'd like to understand them. All it takes is a mind, discipline and time, if you wish to understand things, I would say. However, many studends lack the discipline and that is part of their failure, as I've observed.
Reading GOOD material helps greatly, and it's a very good start, I believe. The 'trick' is how to tell "good" material apart from the rest. That's where a GOOD tutor comes in. The 'trick' then is how to tell a "good" tutor from the rest. That's where discernment comes in.
