Q

Simple Stain

A

Simple staining involves directly staining the bacterial cell with a positively charged dye in order to see bacterial detail, in contrast to negative staining where the bacteria remain unstained against a dark background

Q

Differential Staining

A

What is Differential Staining? Differential staining is a procedure where more than one dye is used to differentiate between different types of microorganisms on a slide. This type of staining helps to differentiate between cell types and cell structures.

A

flat worm

33
Q

cestodes

A

tapeworm

34
Q

COncentration Techniques

A

USED TO INCREASE THE LIKELIHOOD OF DETECTING PARASITES BY CONCENTRATING THE PARASITE FORMS AND SEPARATING PARASTIES FROM FECAL DEBRIS AND HTHUS MAKING THEM EASIER TO SEE

35
Q

Flotation Technique

A

uses solutions of higher specific gravity than the parasites causing the parasites to float to the solutions top while heavier fecal debris settle to the bottom

36
Q

Sedimentation Technique

A

uses solutions of lower spesific gravity than the parasites, causing parasites to collect in the sediment when the specimen is centrifuged

A

infections deeper then skin affecting the muscle and connective tissue

42
Q

Systemic infection

A

affect the lungs and can disseminate to the internal organs or the deep tissues of the body

43
Q

Culturing Fungi Temp and Time
