Viruses of Chelonia

Journal of Veterinary Medicine, Series B, 1993
SummaryViruses occurring in turtles and tortoises are hetergeneous but according to ecologic characteristics and pathogenic properties they can be divided in two major groups:1. Arboviruses(toga‐, flavi‐, rhabdo‐ and bunyaviruses) transmitted by arthropods cause severe diseases in homoiothermic vertebrates.

Abstract 1. 1. Seven species of turtles, Gopherus berlandieri, Terrapene ornata, T. carolina, Clemmys insculpta, Pseudemys scripta, Chelydra serpentina and Trionyx muticus, were analyzed for ornithine-urea cycle enzyme activities and for the nitrogenous wastes in the blood, urine and bladder deposits. 2. 2.

On the Formation of the Germinal Layers in Chelonia

Journal of Cell Science, 1886
ABSTRACT IN the spring of 1884 we made the acquaintance of Mr. Hattori, the proprietor of a large fish-hatching establishment in Honjō, a suburb of Tokyō. His father before him, and he, had succeeded in making the snapping turtle—Trionyx Japonicus, Schlegel—breed freely and naturally in captivity, and thus in furnishing the market with a

Modulated Reproductive Periodicity in Chelonia

Ecology, 1970
After 15 yr tagging at the nesting ground of Chelonia mydas at Tortuguero, Costa Rica, 447 remigration returns have been recorded. These confirm previous indications that some Tortuguero females return to nest every 2 yr and some every 3 yr, with the latter being the more frequent cycle.

KARYOLOGICAL RELATIONSHIPS IN TURTLES (REPTILIA: CHELONIA)

Canadian Journal of Genetics and Cytology, 1972
The mitotic chromosomes of 33 species of chelonians representing 22 genera and six families were investigated. Chromosome number and morphology are the same for most members of a given family and range from 66 in Trionyx to 34 in Pelomedusa. Most emydid genera have 50 chromosomes.

Endoscopic renal evaluation and biopsy of chelonia

Veterinary Record, 2004
Sixty‐nine tortoises, turtles and terrapins representing 28 species of the order Chelonia, class Reptilia were evaluated by endoscopy for renal disease. Under general anaesthesia, coelomic and/or extracoelomic endoscopic evaluations and biopsies of the kidney(s) were undertaken. Endoscopic approaches required a 2 to 4 mm skin incision in the prefemoral

การตรวจหาชิ้นดีเอ็นเอที่มีความจำเพาะต่อเพศในเต่าตนุ Chelonia mydas

เพื่อหาวิธีการตรวจเพศของลูกเต่าตนุโดยลูกเต่าที่ผ่านการตรวจสอบยังคงมีชีวิตอยู่จึงทำการทดลองเพื่อหาชิ้นดีเอ็นเอที่มีความจำเพาะต่อเพศของเต่าตนุโดยใช้เทคนิคทางพันธุวิศวกรรม 2 เทคนิค คือ RFLP (เซาท์เทิร์นบลอทไฮบริไดเซชัน) และ PCR–based DNA fingerprinting ใช้ GATA repeats จำนวน 21 เบส ซึ่งเป็นลำดับเบสที่จำลองมาจากส่วน conserved sequence ใน Bkm sequence ซ ...
