Here are some I’ve done: Life Cycle of Hookworm: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZY5aYYR053Q.html Grandma Remembers Hookworm: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OfWmVl3mvSE.html
" ... typically don't hear much about schistomiasi in the United States .... " ... but you do hear a lot ( if you're listening ) of " idiosyncratic diagnoses . I propose a transmission method not mentioned. Suppose a newly arrived immigrant arrives , from Somolia, Ehiopia, some " Third Wolrd " origin and they don't have a lot of money. Where can you make $50? --- Donate blood. As far as I know, he screening consists of questions , one of which is " have you been overseas recently ? We all know that no one will lie for $$ -- so , -- let's just keep calling things " idiosyncratic". ( if fluke can live up to 10 years in the body, they don't even have to lie ) --- If there is a procedure for screening, filtering , detection & discarding , I'd like to know. I assume it would not bu discarded, but processed for plasma, which I'm sure would eliminate undetectable traces. ( sarc) .. Remember, flukes can also multiply by regrowth. Pieces can regenerate ( stem cells ) into adults.
Dear Professor! Hi, I am someone doing MSc Infections and Immunology. I found your lectures very helpful to me. But I want to double-check with you, that my lecturer told me a schistosoma only lives 10-20 days in an immunocompetent person being. But You said 10 years. Are you sure about it?
“Schistosomes live an average of 3-10 years, but in some cases as long as 40 years, in their human hosts.” www.ncbi.nlm.nih.gov/pmc/articles/PMC4672382/
The estimated life span of schistosome worm is 3-6 years. So, she was true when she said 10 years. It's not 10 to 20 days. But if the cercariae do not penetrate the skin within a few hours, it will die.
I had and still do although less schistosmiasis, I also know a ton of Americans that have them, I heard 80nto 90 percent of all humans have some parasite...
Schistosomiasis and parasites in general are not common in the US. Of course, nearly 100% of humans all over the world have things like mites on their skin (like DEMODEX FOLLICULORUM), but parasites that cause disease (hookworm, schistosomiasis, giardiasis, etc.) are relatively unusual in the US.
I am diagnosed as bladder cancer and my bladder is removed. Now having Chemotherapy, If I have/had Schistosome how I could understand ? should I have blood test or urine test ? also are there any other parasites bacteries causing bladder cancer ?
Please ask your doctor about being tested. Schistosomiasis is the only infection I am aware of that is directly connected to bladder cancer, but I suppose chronic cystitis caused by other infections could also raise the risk.
Typically, it is differences in the morphology of the eggs that help distinguish the species. I don't know if the larvae are different enough to be used to distinguish species. parasite.org.au/para-site/text/schistosoma-text.html
Yes, it can be done for pet snails under advice from a vet. Deworming an entire population of underwater snails in regions of high poverty and low resources (where schistosomiasis mostly occurs) is not very feasible though.
It is the eggs in the urine and they are microscopic. 110-170 µm long by 40-70 µm wide, more or less. So you need a microscope to see eggs in urine. The actual worms are bigger and can be seen with a naked eye, but they will be in the bladder, not the urine.
I apologize for causing offense. It was not my intention to seem insensitive or to seem like I am judging. Every human being deserves a life free from the burden of this kind of disease. I often remind my students that diseases like this only reinforce the cycle of poverty and make it more difficult for individuals and communities to prosper. I am very lucky to live somewhere that I don’t have to worry about schistosomiasis, hookworm, malaria, dengue fever, yellow fever, cholera, etc. I also apologize for lumping so many countries into one “developing countries” category, without acknowledging the diversity of experiences that actually exist.
