Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
The nematode Steinernema feltiae under the microscope, the species used as a biopesticide to infect fungus gnats in agriculture and gardening.

Hemlock woolly adelgid (HWA) infestation on underside of eastern hemlock branch in Connecticut. This tiny sapsucking insect from Asia, discovered in Virginia in 1951, is a major killer of eastern hemlocks, which are vitally important to Northeastern forest ecosystems. HWA is named for its woolly egg masses. Thanks to introduction of the Japanese ladybeetle, a predator of HWA, many hemlocks in Connecticut have survived since the first waves of tree mortality some 35 years ago.

Photomicrograph of an ascus with eight ascospores. This preparation was stained with acid fuchsin, which stains the cytoplasm of the ascospores a deep red color. The fungus is an ascomycete, Diplodia corticola, that infects the wood of oak trees, and is one of the causes of oak decline disease.The picture was taken with a microscope equipped with differential interference contrast optical system that gives a three dimensional effect.

stx2a is a subtype of Shiga toxin-producing E. coli (STEC) linked to Hemolytic Uremic Syndrome (HUS), a severe condition impacting kidney function and blood clotting. STEC poses a significant risk of foodborne illness and can spread within communities including family members.

Raspberry rust is a malignant disease caused by the phytoparasitic fungus Phragmidium rubi-idaei. This pathogen forms small ulcers on the leaves through which a huge mass of orange spores breaks through. Under a microscope, this pathogen does not look so sinister.

WHO says that it is estimated that ETEC causes about 220 million diarrhoea episodes globally, with about 75 million episodes in children under 5 years of age, resulting in between 18 700 and 42 000 deaths in children younger than 5 years. Several vaccines are in the pipeline.\nETEC is also a very common cause of traveler's diarrhea, this infection is usually self limiting, with no need for antibiotics. ETEC is common in developing countries.

Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.

Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
