Oh Boy. I'm not used of people paying this much attention!
"Do you check this yourself or send stools to labs for analysis"?
I check my own samples, because most labs do processed tests, with technicians trained to identify text book particulates. Most have little training in protozology or parasitology and even less in mycology [study of fungi].
So unless things jump out, 'negative' is what you will hear most of the time.
I reviewed a few healthy people as well, which is great information to compare normal from abnormal--did cultures too.
"What do you have"?
I have an infection with microsporidium. This is what to watch for. It is protozoan, but with properties of fungi, and has no mitochondria. Labs all over the world are missing it. Everybody tests mitrochrondrial DNA when doing PCR scans, and you have to "break" the cells open before doing a run, which they often fail to do as well. Plus, you have to have the right primers, which cost money and must be ordered in most cases.
"Has a negative correlation between lactobacteria and yeast/ parasites
been been proven in scientific trials"?
Yes. But the studies often involve animals in agricultural setting.
When animal looses the upper gut bacteria, the gram negative types increase. This places burden on lower bowel to digest food, causing higher ammonia output which is bad for environment etc. [hence the interest in doing the study]
Porcine studies are best to examine when making comparisons to humans.
"Are all gram negative bacteria 'bad' bacteria? What are lacto-rods? When you say 'temporary', are you saying you only take them for short periods or that the probiotics are transient"?
In a way, your "bad bacteria" are more important than the good, but you need a balance of both. All bacteria are connected to the host in ways we are just beginning to understand. It does involve chemical mediators, especially hormones. I am saying the probiotics will lose viability with time, unless supported by the host's hormonal balance.
Lacto-rods are the main types in upper gut, and produce lactic acid. They are important for enzyme production and many other important functions. In affected individuals, the lacto bacteria is mostly transient, but also killed off or consumed by predatory microbes such as protozoa, yeasts.
"What other hormone factors"?
Things like adrenaline, norepinephrine, serotonin, dopamine, melatonin, all of these, and their subunits, and neurotransmitters etc. Some have negative effect, some have positive effect.
[If some of you guys want to research this in better depth, and obtain links to recent reports, that will help me out in a big way time-wise].
As for the chininase producing bacteria......
Gut bacteria that produce chitinase [an enzyme that breaks down chitin] could reduce the number of fungal spores that eventually lead to yeasts. Some yeasts including candida, have a tough outer membrane wall made of....chitin. The microbes that cause most systemic chronic symptoms have cysts made of this. You can see the importance of having this enzyme around. The body produces it, but microbes may block it's production in macrophages[hypothetically].
