 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Hematozoa of Snakes in Queen Saovabha Memorial Institute) ผู้เขียน: นายเจริญศักดิ์ ศาลากิจ, รองศาสตราจารย์ , ดร.เฉลียว ศาลากิจ, ศาสตราจารย์ , นางสาวนวลอนงค์ นาคคง,  Lawan Chanhome, Nirachra Rochanapat, Piyawan Suthunmapinunta สื่อสิ่งพิมพ์:pdf AbstractDuring December 1997 to March 2001, 275 blood samples of snakes from eighteen species of four families, including Pythonidae, Colubridae, Elapidae and Viperidae, at Queen Saovabha Memorial Institute were examined for blood parasites. 111 samples (40.4%) were positive for hematozoa infections. The single infection (38.2%) were following genera : Hepatozoon (32.4%), Haemogregarina (4.0%) and trypanosome (1.8%). The incidence rates of mixed infections between Hepatozoon and Haemogregarina and between Hepatozoon and trypanosome were 0.4% and 1.8% respectively. Hepatozoon infections were found in mangrove snake (Boiga dendrophila melanota), mask-faced water snake (Homalopsis buccata), rainbow water snake (Enhydris enhydris), copper head racer snake (Elaphe radiata), common rat snake (Ptyas mucosus), Siamese spitting cobra (Naja siamensis), golden spitting cobra (Naja sumatrana), king cobra (Ophiophagus hannah), banded krait (Bungarus fasciatus), Malayan krait (Bungarus candidus), mangrove pit viper (Trimeresurus purpureomaculatus) and Siamese russell’s viper (Daboia russellii siamensis). There were three types of gamont of Hepatozoon sp., including small gamont (3.0 ? 10.9 ?m, n=120), medium gamont (3.3 ? 14.8 ?m, n=60) and the large gamont (3.9 ? 15.0 ?m, n=140). Haemogregarina infections were found in Burmese python (Python molurus bivittatus), mangrove snake, mask-faced water snake and rainbow water snake. The gamonts of Haemogregarina sp. were very large (7.6 ? 15.2 ?m, n=40). Trypanosomes were found only in mask-faced water snake and rainbow water snake. They were large flagelate hematozoa with 10-20 ?m body width (14.1 ? 3.0 ?m, n=120). |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Hematology, Morphology and Ultrastructure of Blood Cells and Blood Parasites from Puff-faced Watersnakes (Homalopsis buccata)) ผู้เขียน:ดร.เฉลียว ศาลากิจ, ศาสตราจารย์, นายเจริญศักดิ์ ศาลากิจ, รองศาสตราจารย์, Piyawan Suthunmapinunta, Lawan Chanhome สื่อสิ่งพิมพ์:pdf AbstractBlood samples of 45 puff-faced watersnakes (Homalopsis buccata) in the Queen Saovabha Memorial Institute were collected from ventral caudal vein for both basic hematology and light microscopic, scanning and transmission electron microscopic features of blood cells. Seventeen samples (37.8%) were positive for hematozoa infections. The single infection of Hepatozoon sp., trypanosome and Haemogregarina sp. was found in 4, 4 and 5 snakes respectively. The other four snakes were infected by both trypanosome and Hepatozoon sp. There were no significant differences of all hematological value between the hematozoa-negative and the hematozoa-positive snakes except fibrinogen concentration which was found higher in the negative group. Lymphocytes were the most commonly observed leukocytes and average 6- 8 ?m in diameter. Azurophils were the second most commonly observed leukocytes, average 10-17 ?m in diameter and might play a major role in eliminating the trypanosome. Heterophils were the largest leukocytes, average 16-19 ?m in diameter and the third commonly observed leukocytes. Eosinophils usually were medium-sized cells, average 10-14 ?m in diameter but in some occasion the very large cells were also detected. Basophils were smaller than heterophils and eosinophils. Scanning electron microscopy revealed the membrane surfaces of normal and abnormal erythrocytes, Hepatozoon sp. infected erythrocytes, thrombocytes, eosinophil and trypanosomes. Transmission electron microscopy revealed the organelles within azurophil, eosinophil, heterophil and trypanosome. |
