Hematology, cytochemistry and ultrastructure of blood cells in fishing cat (Felis viverrina)

Abstract

Hematological, cytochemical and ultrastructural features of blood cells in fishing cat (Felis viverrina) were evaluated using complete blood cell counts with routine and cytochemical blood stains, and scanning and transmission electron microscopy. No statistically significant difference was found in different genders of this animal. Unique features of blood cells in this animal were identified in hematological, cytochemical and ultrastructural studies. This study contributes to broaden hematological resources in wildlife animals and provides a guideline for identification of blood cells in the fishing cat.

Hematologic, cytochemical, ultrastructural, and molecular findings of Hepatozoon‐infected flat‐headed cats (Prionailurus planiceps)

“…This is the first report to describe the hematologic findings of flat‐headed cats. Most hematologic findings and blood cell morphology were similar to those of another wild cat in Southeast Asia, the fishing cat ( Felis viverrina ), 5 as well as domestic cat 6 . Some differences were observed, however, which may be species‐related or may be the result of Hepatozoon infection.…”

“…These data support species heterogeneity in eosinophil morphology. The cytochemical staining reactions of eosinophils were similar to those of domestic cats 2 but different from those of the fishing cat 5 . The ultrastructural findings for other leukocytes and platelets were not different from those of fishing cats or other mammals 5,9 …”

“…The eosinophil granules in flat‐headed cats were different from those of domestic cats, which contain a crystalloid region, 9 and were also different from those of fishing cats, which are homogeneous 5 . These data support species heterogeneity in eosinophil morphology.…”

The method matters: The effect of handling time on cortisol level and blood parameters in wild cats

“…Basal level of RBC in far‐east wild cats was higher than in most cat species (Caro et al., ; Kocan et al., ; Prihirunkit et al., ; Salakij, Prihirunkit, Narkkong, Apibal, & Tongthainun, ), but very similar to leopard cat ( P. bengalensis ), which was physically immobilized also without anesthesia within an hour (Salakij et al., ). We showed that RBC number decreased in 20 min after the beginning of capture procedure.…”

“…During the last 30 years, the use of blood profiles to estimate the welfare of wild cats in both captive and wild settings has become a usual practice among zoo veterinaries and field zoologists. At present, for 17 of the 38 wild cat species blood profiles have been obtained and described in scientific literature (Akuzawa, Mochizuki, & Yasuda, ; Brown, Lappin, Brown, Munkhtsog, & Swanson, ; Caro et al., ; Dunbar, Nol, & Linda, ; Erasmus, ; Kocan, Blouin, & Glenn, ; Marco, Martinez, Pastor, & Lavin, ; Prihirunkit, Salakij, Apibal, & Narkkong, ; Salakij, Salakij, Narkkong, Sirinarumitr, & Pattanarangsan, ,b, b, , , and others). However, blood profiles can be influenced significantly by the sampling procedure, including capture method, type of anesthesia, and time to blood collection (Moen, Rasmussen, Burdett, & Pelican, ; Serieys et al., ).…”
