Laboratory diagnosis of parasitic infections ppt?
Are you tired of boring lab lectures about parasitic infections? Do you want to shake things up in your classroom, impress your professor or amaze your colleagues with some gross-out photos? Well, look no further – we’ve got the perfect solution for you! This comprehensive guide will teach you everything from body fluid tests to fecal floatation techniques.
Introduction
Before we get into the nitty-gritty of laboratory diagnosis, let’s talk a little bit about parasites. They’re pretty much everywhere; they can be found on land, water or even inside animals (including humans!) To put it simply, these tiny creatures live off their hosts by feeding on their blood and tissues. Some common types include tapeworms, roundworms and flukes.
Why is laboratory diagnosis important?
While many parasitic infections are harmless or cause mild symptoms that go away on their own like an annoying itch or cramping belly ache (I mean who doesn’t love being uncomfortably itchy?), others can be life-threatening if not diagnosed in time. Lab analysis helps to identify the presence of parasites in samples such as blood plasma/sperm/semen (yep!)or stool samples.
Now that we understand why diagnosis is important let’s move on to how certain techniques work:
Blood films
Let’s start with blood films. Blood films are useful for diagnosing malaria and babesiosis (a rare disease caused by tick bites). The technique involves placing a small drop of blood onto a slide then staining it with Giemsa stain, which makes any parasites present display vividly red when viewed through a microscope.
Serological Tests
Serological tests enumerate antigen-antibody reactions in serum compounds taken from potential carriers’ bloodstream via immunological markers & help detect protozoan parasites like amoeba, leishmania & trypanosomes.
Fecal Floatation
Stick the poop in water!
One of perhaps the most simple yet effective methods to diagnose gastrointestinal parasitic infections, including tapeworm or roundworm. The fecal matter dissolves into a solution under headspace (science term alert) which will cause any eggs present in it to float above and sit on top. This wastewater can then be extracted using pipettes (suction device u use cause ur mouth is not a tool!) onto slides where they are carefully analyzed for evidence of parasites/eggs/or cysts.
Conclusion
By now you should have a basic understanding of how laboratory diagnoses work when diagnosing parasitic infections. It goes well beyond these techniques, but we hope that introducing just these few has been an enjoyable read filled with juicy details so that you can impress all your horny (ahem I meant “honest”) friends over coffee while discussing bioanalytics at Starbucks from here on out!
