The basic cytodiagnosis of inflammation, tissue hyperplasia, malignant neoplasia and normal cellu- larity are easily differentiated from each other (see Figures 10. One who is well versed in mammalian cytodiagnosis should have little trouble in the interpretation of avian samples. The goal is to 10 achieve a quick presumptive or definitive diagnosis during the patient’s initial visit to the veterinary clinic in an effort to provide an immediate and spe- cific treatment plan. Cytology can then be used to monitor the success of therapy by evaluating changes in microbial and cell populations within or on the host. Cytology should be considered as a part of the minimum database in birds with discharges, masses or swellings. Cytological samples are of greatest value if they are collected fresh and immediately processed for evaluation. To obtain a cytologic sample and send it to an outside laboratory defeats the purpose and usefulness of cy- Terry W. This will serve to improve understanding of the pathogenesis and cellular effects of a disease process. The needle is moved at different angles in the tissue without releasing the vacuum. It is impor- Sample Collection tant to release the vacuum before withdrawing the needle from the tissue, because the aim of the proce- dure is to obtain a small amount of sample in the lumen of the needle only, not in the syringe itself. A variety of sample collection methods can be used to Once the needle has been withdrawn from the tissue, obtain samples for cytologic examination. Cytologic sample inge, and with the point of the needle lying against collection methods can be divided into two broad the slide surface, the air within the syringe is used to categories: aspiration and contact smears.

Two specimens for cytologic examination are sive procedure for obtaining material for cytologic thus created. Using an alcohol swab, the “squash preparation technique” because the sam- the skin overlying the biopsy site is cleansed and ple is compressed between the two slide surfaces. A hypodermic needle (eg, 22 ga, Abdominocentesis is an aspiration biopsy procedure one-inch needle) attached to a syringe (12 ml or used to collect cytologic samples from birds with larger) is inserted into the tissue to be sampled. The abdominal space vacuum is applied to the syringe using the syringe is small in normal birds and contains little fluid. Because the abdominal air sacs occupy a large por- tion of the abdomen, it is difficult to enter the perito- neal cavity of normal birds. However, as peritoneal fluids accumulate, the air sacs are compressed later- ally, increasing the size of the peritoneal cavity and making it easier to sample. Abdominocentesis begins with a surgical preparation of the site along the ventral midline just distal to the point of the keel. The needle (21 to 25 ga, one-inch) is attached to a syringe and is directed through the body wall at the midline, pointing toward the right side of the abdo- men to avoid the ventriculus, which lies to the left of the midline (Figure 10. The abdominal fluid is aspirated into the syringe and prepared for cytologic examination, either by making a direct smear as one would prepare a blood film or by using a concentra- tion method. The goal of abdominocentesis is to collect fluid from the abdominal cavity for diagnostic purposes. The material that is collected (eg, gut contents, unwillingness to fly and depression. The hen had been incubating egg yolk, cells from a mass) should be evaluated with eggs, and it was uncertain how long she had been clinically symp- respect to its potential source.

Articular gout is common in birds that become dehydrated or that have primary or secondary renal disease. The fluid is placed in a plastic test tube and centrifuged at 600 G (gravity) for ten minutes. Unlike urine sediments, cytologic sediments from poorly cellular fluids do not have a visible button or pellet at the bottom of a spun tube. Therefore, the concentrated cells are usually obtained by aspirating the fluid at the bottom of the tube into a pipette or syringe. The sample is then placed onto a microscope slide and a smear is made in the manner described for concentrating cells in a smear. Special cytocentri- fuge equipmenta is available for concentrating cells on microscope slides while absorbing the fluid onto filter paper. This equipment is expensive and not practical for the average veterinary laboratory. Because centrifugation distorts the appearance of the cells, a cell concentration method that utilizes gravity provides a concentrated sample with normal appearing cells. A simple, inexpensive sedimentation device can be made for use in the veterinary labora- tory.
