Microsporum canis

Photomicrograph (magnification of 475X) of the fungus Microsporum canis revealing some of the ultrastructural morphology, large spindle-shaped macroconidia. This organism is a zoophilic dermatophyte often found in cats and dogs. It belongs to the Ascomycota phylum and frecuently causes of tinea corporis and tinea capitis in humans. The infection can affect skin on almost any part of the body as well as fingernails and toenails. Symptoms typically appear between 4 and 14 days after the skin comes in contact with the fungi.

Legionella pneumophila

Legionella pneumophila image under a magnification of 43,700X (transmission electron microscopy (TEM) - negatively stained - uranyl acetate) showing the organisms in the process of cell division. This organism causes Legionellosis. Infection is typically caused by inhalation of mist from water that contains the bacteria. The mist may come from hot tubs, showers, or air-conditioning units in buildings. Infection can lead to two different illnesses: Legionnaires’ disease or Pontiac fever.

This bacteria is a gram-negative, microaerophilic free-living soil organism. This microbe is able to fix nitrogen and thus plays an important role in the environmental nitrogen cycle. Nitrogen fixation is a process where atmospheric nitrogen (N2) is converted into ammonia (NH3) and other compounds making these available for uptake by other organisms.
