What is the inclusion depicted in this image called? pic42(1).jpg  

Several people from a picnic came down with a gastrointestinal disturbance, and public health officials suspected a case of food poisoning. The food, especially hot dogs, were cultured and after 24 hours of growth on sheep blood agar (SBA), there was a small, round, smooth, translucent colony surrounded by a narrow zone of β-hemolysis. A Gram stain showed short, gram-positive rods. Motility medium was inoculated and an umbrella pattern of motility was observed at room temperature. What organism was isolated as the cause of the illness?

 A microbiologist is reading an anaerobic culture and observes a double zone of hemolysis on an anaerobically incubated sheep blood agar plate. The Gram stain of that organism was a spore-forming, gram-positive bacillus. What organism is this?

What bacteria’s morphology is described as large, box-car, square-ended, gram-positive or gram-positive rods found singly or in chains?

Why is it that although Nocardia spp. grow well on most common nonselective laboratory media, many are missed when the cultures are read?

 How long are anaerobic cultures routinely held in the laboratory?

What type of blood is shown in the image?

Identify the structure A.

Name the blood cell shown in the image.
