OK - as promised i am updating this thread with my latest run of slides - this time taking capillary blood from an ear lobe - as per Dr Lindner's method - then staining with Giemsa stain as before.
i had some technical issues which made getting perfect resolution pretty hard.
The task of achieving perfect resolution of objects much smaller than red blood cells with transmission light microscopy is quite tricky in the first place, as its right on the lower limit of what is possible and requires everything in the preparation and equipment to be optimised.
this is critical because we really need high definition to tell these very small objects apart from random artefacts and formations of debris etc.
for example - when looking for piriform shapes - something appearing as piriform could be a single piriform organism - or it could be a small random object next to another slightly larger one - and due to the poor resolution - these two different things can appear exactly the same under the microscope.
so, when sampling many slides and many objects within them - it may be possible to find suspect looking things that are simply random debris - rather than organisms.
this is especially so as the same regions of the slides that we are told to look at according to Dr L's method - areas around blue stained fragments of "fibrin nests" and areas around small clots - are areas that are typically pretty chaotic and littered with fragments of debris.
that said, there are some rather suspicious objects in some of the slides - and i will try to share a few images below so you can see what i mean
this 1st slide is of a an area with a typical chunk of blue crystalline looking "fibrin nest material"
there are a lot of objects that could be described as piriform or coke-bottle-shaped - of about
the right size for babesia (approx. 1/4 to 1/2 the diameter of a RBC) and picking up purple and pink stain as apicomplexans do with Giemsa stain
VIEW IMAGEIn the slide below I was photographing what looked like platelet aggregates and activated white blood cells ( i saw a lot of those - much more than i saw in the venous blood slides previously) and it wasn’t until reviewing later that I noted that there seem to be quite a number of elongated suspicious shapes that were picking up stain in some of the red blood cells or around them – I was centred on the platelets so the focus is not ideal – but they are all the right size – all elongated or pear shaped – one is a crescent shape (red arrow) - and all picking up stain in pink and purple colours like babesia. And something was causing the WBC’s to be activated in the first place ….. interesting
VIEW IMAGEthere were not many chunks of blue "fibrin nests" in my sample" probably because i have been taking fibrinolytic enzymes for some months now - so i looked at more of these areas with activated white blood cells
this image is about
the maximum magnification i can achieve
a white blood cell – a neutrophil I think – Is clearly activated and seems to be trying to absorb red blood cells. Then on closer inspection I saw several clearly stained piriform or crescent shapes (from Schaller Babesia lab guide these crescents are typical Babesia forms – esp crescents with dot on each end) - also what looks like a coke bottle shape piriform – so perhaps that what has activated the WBC..... - note what look like 3 grouped intracellular piriformis top right also
VIEW IMAGEfinally - i went back to review previous images i had saved of blue crystalline deposits from earlier slide runs and here i found the clearest example of a piriform shape yet - per Dr Lindner
– see solid red circles – and others that are somewhat similar but less convincing – see dashed red circles
VIEW IMAGEwhen viewing these we have to bear in mind - that when looking for something through hundred of images we are likely to find things that look like what we are looking for - and that random debris can easily look like piriform shapes - but, even so, i am leaning towards this being Babesia
esp when taken alongside the activated white blood cells, and the blue fragments.
i plan to do another run to see if i can improve resolution and make it more definitive
-more slides - more chances
-better stain - better definition / less noise
-sample other capillary
