Hematological and serum biochemical values of white ibis (Threskiornis melanocephalus)

Hematological and biochemical values are important for diagnosis of clinical signs, showing how disease processes change. This is the first report to demonstrate hematological and serum biochemical values of white ibis (Threskiornis melanocephalus) in Thailand, which are rare species in tropical countries. The study was carried out in ten healthy white ibises (male, n=5; female, n=5), at the age of 4 years from Khow Khoew Open Zoo, Chon Buri province, Thailand. The results revealed the following information: total red blood cell, hemoglobin concentration, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total white blood cell, percentage of lymphocyte,percentage of heterophil, percentage of monocyte, percentage of eosinophil, percentage of basophil and thrombocyte of white ibis were 2.78±0.70 × 106 cells/µl, 18.75±1.32 g/dl, 46.00±3.59%, 173.51±38.52 fl, 70.73 ±15.42 g/dl, 40.82±1.65 pg, 1.49± 0.66 × 104 cells/µl, 89.70±6.40%, 8.50±6.34%, 0.50±0.97%, 0.90±1.29%, .30±0.95% and 16.2±0.49 × 103 cells/µl, respectively. Serum biochemistry values i.e. serum glucose, serum creatinine, serum glutamic oxaloacetic transaminase, and serum glutamic pyruvic transaminase of white ibis were 12.55±1.90 mmol/dl, 69.95±13.05 mmol/l, 204.82±56.76 IU/L and 30.43±8.66 IU/L, respectively. Hematological and biochemical values between males and females white ibis were not significantly different (P>0.05)

A study on karyotype of the pileated gibbon, Hylobates pileatus (Primates, Hylobatidae), by conventional staining

Cytogenetics of the pileated gibbon (Hylobates pileatus) at Nakhon Ratchasima Zoo, Thailand, was studied. Bloodsamples were taken from two female and two male gibbons. After lymphocyte culture, the mitotic chromosome preparationwas done by hypotonic-fixation-air-drying method and conventional Giemsas staining. The results show that diploid chromosomenumber was 44 (2n=2x=44), and the fundamental number (NF) were 88 chromosomes in both female and male.The autosomes consist of 12 large metacentric, 6 medium metacentric, 2 medium submetacentric, 2 medium acrocentric, 12small metacentric and 8 small submetacentric chromosomes. In addition, the chromosome 15 showed clearly observablesatellite chromosomes. The X chromosome was a medium submetacentric chromosome and the Y chromosome was a tinyacrocentric chromosome. The karyotype formula for the pileated gibbon is as follows:2n (44) = Lm12+Mm6+Msm2+Ma2+Sm12+Ssm8+sex-chromosome

A comparative chromosome analysis of Thai wild boar (Sus scrofa jubatus) and relationship to domestic pig (S. s. domestica) by conventional staining, G-banding and high-resolution technique

This research is the first comparative chromosome analysis report of Thai wild boar (Sus scrofa jubatus) and its relationship to domestic pig (S. s. domestica) by conventional staining, G-banding and high-resolution technique. Blood samples of the Thai wild boar were taken from two males and two females kept in Nakhon Ratchasima Zoo. After standard whole blood lymphocyte culture at 37 oC for 72 hr. in the presence of colchicine, the metaphase spreads were performed on microscopic slides and airdried. Conventional staining, G-banding and high-resolution technique were applied to stain the chromosomes. The results showed that the number of diploid chromosomes of Thai wild boar was 2n (diploid) = 38, and the fundamental numbers (NF) were 62 in the male and female. The type of autosomes were 12 metacentric, 14 submetacentric, 4 acrocentric and 6 telocentric chromosomes, with X and Y chromosomes being metacentric chromosomes. We found that chromosomes 1, 5, 7, 8, 10, 11, 12, 13, 14, 16, 17, 18, X and Y had the same Gbanding and high-resolution technique patterns as those of domestic pig chromosomes. Chromosomes 2, 3, 4, 6, 9 and 15 are similar to those of domestic pig chromosomes. These results show the evolutionary relationship between the Thai wild boar and the domestic pig

Cytogenetics of Stump-tailed Macaque, Macaca arctoides (Primate, Cercopithecidae) in Thailand by Conventional Staining

The cytogenetics of the stump-tailed macaque (Macaca arctoides) in Thailand was studied. Blood samples were collected from this species maintained in Nakhon Ratchasima Zoo and Songkhla Zoo. After standard whole blood lymphocytes were cultured in the presence of colchicine, metaphase cells were spreaded on the slide and air-aired. Chromosomes were observed using Conventional Giemsa staining under a light microscope. The results show that the number of diploid chromosomes of the stump-tailed macaque is 2n=42, and the fundamental number (NF) are 84 chromosomes in the female and male. The types of autosomes are 6 large metacentric, 8 large submetacentric, 4 medium metacentric, 12 medium submetacentric, 8 small metacentric and 2 small submetacentric chromosomes. In addition, the pair of chromosome 13 is a clearly observable satellite chromosome. The X chromosome is medium submetacentric and the Y chromosome is the smallest submetacentric chromosome

The first chromosome characterization of the family Tragulidae (Artiodactyla) in Thailand by conventional staining

Karyotypes were studied from the family Tragulidae of Thailand, representing a single genus with two species namely; lesser Malay mouse-deer (Tragulus javanicus) and larger Malay mouse-deer (Tragulus napu). Blood samples were taken from the two species kept in Khoa Kheow Open Zoo, Chonburi province and Songkhla Zoo, Songkhla province,Thailand. After standard whole blood lymphocyte culture in presence of colchicine, the metaphase spreads were performed on microscopic slides and air-dried. Conventional Giemsa’s staining was applied to visualize chromosomes. The karyotype of lesser Malay mouse deer showed that diploid chromosome number was 2n=32 and fundamental numbers (NF) were 64 in both female and male. The autosomes consist of 6 large metacentric, 6 large submetacentric, 14 medium metacentric,2 submetacentric and 2 small metacentric chromosomes. The X chromosome was a large submetacentric chromosome while the Y chromosome was a small metacentric chromosome. For our result, the first karyotypic study of T. napu, the larger Malay mouse-deer, the karyotype shows that diploid chromosome number was 2n=32, and NF were 64 in both female and male. The autosomes consist of 6 large metacentric, 6 large submetacentric, 12 medium metacentric, 2 medium submetacentric, 2 medium acrocentric and 2 small submetacentric chromosomes. The X chromosome was a large submetacentricchromosome while the Y chromosome was the smallest metacentric chromosome

Blood cell characteristic, hematological and serum biochemistry values of Painted Stork (Mycteria leucocephala)

Blood cell characteristics, hematological and serum biochemistry values were examined in 10 mature healthy Painted Storks (Mycteria leucocephala) (5 males and 5 females) from Khow Khoew Open Zoo, Chonburi province, Thailand. The morphology of erythrocytes, leukocytes and thrombocytes were similar to those of other avian species, but oval shaped granules of heterophils were less stained by Giemsa-Wright solution. Erythrocytes, hemoglobin, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total white blood cells, percentage of leukocytes (lymphocyte, heterophil, monocyte, eosinophil, basophil), thrombocytes, serum glucose, serum creatinine, serum glutamic oxaloacetic transaminase and serum glutamic pyruvic transaminase values of Painted Storks were 3.24 + 0.82 106cells / μl, 0.82 106cells /μl, 17.67 + 1.56 g/dl, 42.40 + 3.57 %, 139.47 + 38.70 fl, 58.56 + 18.24 g/dl, 41.76 + 2.90 pg, 3.88 + 2.60 104cells /μl, 76.10 + 10.28 %, 10.60 + 9.49 %, 0.00 + 0.00 %, 12.00 + 8.54 %, 1.00 + 1.33 %, and 1.29 + 0.42104cells /μl, 270.50 + 42.85 mg/dl, 6.19 + 1.70 mg/dl, 249.47 + 42.19 IU/L and 124.29 + 8.81 IU/L, respectively. Total erythrocytes and mean corpuscular volume (MCV) differed significantly between male and female Painted Stork (P < 0.05)

High resolution karyotype of thai crab-eating macaque (Macaca fascicularis)

Comparative chromosome banding analysis and/or fluorescence in situ hybridization (FISH) studies are established approaches to compare human and ape chromosomes. FISH-banding is a relatively new and not routinely applied method suited very well to provide to a better understanding of the evolutionary history of primate and human phylogeny. Here multicolor banding (MCB) applying probes derived from Homo sapiens was used to analyze the chromosomes of Thai crab-eating macaque (Macaca fascicularis). The results agree with those of previous studies in other macaques, e.g. Macaca sylvanus or Macaca nemestrina. This result pinpoints, that morphological differences within the Ceropithecoidae must be founded rather in subchromosomal changes or even in epigenetics than in gross structural alterations
