Tomopteris

Tomopteris is a marine planktonic group of polychaete worms. They are very common in all they oceans and seas, many of them living in the deep-sea. All of these tomopteris species emit blue light, called luminescence. Tomopteris helgolandica emits also a yellow light. All Tompteris are transparant . It feeds on other plankton members. (…

Fungus grown on bark

I came across this fungus growing on dead bark of betel nut tree. I picked few fungus, observed there and then using paper slide and cello-tape which I carry in my foldscope kit. I collected the bark sample to prepare the slide of the fungus using Lactophenol blue stain for identification.

Spirochetes in rumen fluid

DBT Foldscope scheme – “Foldscope for diagnosis of rumen acidosis and parasitic infections in cattle” Spirochetes are motile, spiral bacteria. Bovine rumen fluid contains large numbers of spirochetes. Spirochetes are capable of fermenting polymers that are commonly present in the plant materials. Polymers such as xylan, pectin and arabinogalactan are used as substrate by spirochetes….

Holotrich Protozoa identification in a field setting

DBT Foldscope scheme – “Foldscope for diagnosis of Rumen acidosis and Parasitic infection in cattle”. This post is in response to Manu Prakash’s comment on our previous post (Holotrich protozoa – from Rumen fluid). Rumen fluid was collected from an healthy cow  (Figure 1) in a sterile container (figure 2).  A drop of rumen fluid was…

Spores of Fern

Ferns are reproduced from spores that are gathered in clusters called sori, which are usually on the underside of the fronds. The spores can be yellow, green, brown, or black. The sori are sometimes covered with a membrane called an indusium, which will lift up when the spores are ripe.

Fungus

The fungus was isolated from a plates exposed to air and the slide was prepared using no stain. the identification part is still going on.

Workshop on Foldscope at Meghalaya, India

The prop roots of Ficus elastica (rubber tree) are trained over 15-20 years to form the natural living bridge to cross rivers and streams found in Meghalaya. The bridges grow to approximately 50 to 100 feet long and have strong and deep interwoven prop roots providing a boat-shaped foothold. A workshop on Foldscope has been…
