LACRYMOCYTE
Definition: Erythrocyte with a tear-drop shape. The central pallor shall be seen.
(the cells are different from pseudolacrymocytes, which have pinched cytoplasm on one of the poles.These cells are observed excessively at the thin parts of the blood film.
Occurrence in blood: normally not present
Comment: In the picture three lacrymocytes are seen. Besides, ovalocytes and anisocytosis are seen. Staining: MGG
Magnification: x 1000

TARGET CELL
Definition: Erythrocyte containing dark stained central area surrounded by lightly stained ring of cytoplasm without hemoglobin.
Occurrence in blood: < 2 % of erythrocytes in normal blood. Sometimes cells may be seen in vitro and may cover large area of the blood film, separated from the area of normal red cells.
Comment: The arrow indicates one of two target cells. Staining: MGG
Magnification: x 1000

Normal Bone Marrow: SUDAN BLACK B REACTION
Reaction product: green or green- black granules, where the lipids are present.
Occurrence:
Neutrophils: positive reaction from the stage of promyelocyte or myeloblast to segmented neutrophils
Basophils: variable reaction, positive or negative
Eosinophils: strong positive reaction from the stage of promyelocyte to segmented leucocyte
Monocytes: a few fine granules, in some of the cells the reaction may be negative.
Lymphocytes, erythroblasts and megakaryocytes do not contain lipids
Staining: Sheehan & Storey method
Comment: Most cells show positive Sudan reaction. These are the granulocytes or the monocytes. Magnification: x 500

Alcaligenes faecalis
Small, grey, smooth colonies which cause no alteration of the blood. The culture has been incubated at 30°C.
General characteristics: Gram-negative. Catalase- and oxidase-positive. Motile. Obligately aerobic. Does not attack sugars. As non-fermentative Gram-negative rods, they are art of the psychrotropic spoilage flora of raw foods. Optimum temperature for growth is 20 - 37°C
