Abstract
BACKGROUND Despite their popularity, hematology reference intervals (RIs) have not been established in big-bellied seahorses (Hippocampus abdominalis). OBJECTIVE The objectives of this study were to establish hematologic RIs to compare values between sex in regard to cytochemical staining of blood cells. We also sought to compare white blood cell concentrations using the Natt and Herrick technique vs blood smear estimates. METHODS Forty-three healthy individuals from the Aquarium du Québec (22 females and 21 males) were included. Normal health status was confirmed by an unremarkable physical examination in five individuals and by necropsy of five other individuals, of which all were excluded from further analyses. Venipuncture was performed from the ventral coccygeal vein in the remaining 33 individuals without anesthesia using heparinized insulin syringes. A blood volume of 0.05 to 0.1 ml was collected to prepare Wright Giemsa-stained blood smears and hematocrits immediately after venipuncture. Whole blood was stored in heparinized Eppendorf tubes to determine red and white blood cell concentrations using the Natt and Herrick technique with a hemocytometer in 10 individuals; these results were compared with blood smear estimates. Additional blood smears were stained with alkaline phosphatase substrate, periodic acid Schiff, and toluidine blue stains. RESULTS The reference intervals included the packed cell volume (27.4-67.5%), thrombocyte count (19.5-197.7 × 109 /L), and white blood cell (WBC) count (2-54.8 × 109 /L), including neutrophils (1.1-21.3 × 109 /L), lymphocytes (2.7-45.5 × 109 /L), and monocytes (0-2.2 × 109 /L). The WBC hemocytometer counts showed no correlation with blood smear estimates (Spearman's rho = 0.2). There was also no significant difference between the sexes. CONCLUSIONS These preliminary reference intervals will help assess the health of seahorses.

Left shift and toxic change in heterophils and neutrophils of non-mammalian vertebrates: A comparative review, image atlas, and practical considerations. Vet Clin Pathol 2022; 51:18-44. [PMID: 35199862 DOI: 10.1111/vcp.13117] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 12/02/2021] [Accepted: 01/11/2022] [Indexed: 11/30/2022]
Abstract
Heterophils and neutrophils are important first cellular responders to inflammatory conditions. In addition to quantitative shifts in the numbers of these cells in blood, inflammatory disease states often have accompanying increases in immature precursor stages (left shift) and/or evidence of toxic change on blood film evaluation. Recognition of left shift and toxic change morphologies is a salient diagnostic finding with clinical relevance across species. The objectives of this report are to (a) review heterophil and neutrophil function and structure across the vertebrate animal kingdom, (b) compare morphologic features of left shift and toxic change in heterophils and neutrophils of non-mammalian vertebrates (NMV) to mammals, (c) provide an image guide demonstrating the breadth of morphologic diversity of heterophil and neutrophil lineages in health and disease across taxa, and (d) discuss practical considerations for clinical pathologists and other professionals involved in the recognition and interpretation of observations in the inflammatory leukogram of NMV.

The White-Spotted Bamboo Shark Genome Reveals Chromosome Rearrangements and Fast-Evolving Immune Genes of Cartilaginous Fish. iScience 2020; 23:101754. [PMID: 33251490 PMCID: PMC7677710 DOI: 10.1016/j.isci.2020.101754] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Revised: 09/17/2020] [Accepted: 10/28/2020] [Indexed: 01/27/2023] Open
Abstract
Chondrichthyan (cartilaginous fish) occupies a key phylogenetic position and is important for investigating evolutionary processes of vertebrates. However, limited whole genomes impede our in-depth knowledge of important issues such as chromosome evolution and immunity. Here, we report the chromosome-level genome of white-spotted bamboo shark. Combing it with other shark genomes, we reconstructed 16 ancestral chromosomes of bamboo shark and illustrate a dynamic chromosome rearrangement process. We found that genes on 13 fast-evolving chromosomes can be enriched in immune-related pathways. And two chromosomes contain important genes that can be used to develop single-chain antibodies, which were shown to have high affinity to human disease markers by using enzyme-linked immunosorbent assay. We also found three bone formation-related genes were lost due to chromosome rearrangements. Our study highlights the importance of chromosome rearrangements, providing resources for understanding of cartilaginous fish diversification and potential application of single-chain antibodies.
