Characterization of serum complement activity of saltwater (Crocodylus porosus) and freshwater (Crocodylus johnstoni) crocodiles

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2006
We employed a spectroscopic assay, based on the hemolysis of sheep red blood cells (SRBCs), to assess the innate immune function of saltwater and freshwater crocodiles in vitro. Incubation of serum from freshwater and saltwater crocodiles with SRBCs resulted in concentration-dependent increases in SRBC hemolysis. The hemolytic activity occurred rapidly,

Molecular phylogenetic analyses of genus Crocodylus (Eusuchia, Crocodylia, Crocodylidae) and the taxonomic position of Crocodylus porosus

Molecular Phylogenetics and Evolution, 2010
The genus Crocodylus consists of 11 species including the largest living reptile, Crocodylus porosus. The current understanding of the intrageneric relationships between the members of the genus Crocodylus is sparse. Even though members of this genus have been included in many phylogenetic analyses, different molecular approaches have resulted in ...

Pharmacokinetics of tildipirosin in estuarine (Crocodylus porosus) and freshwater (Crocodylus siamensis) crocodiles

The Veterinary Journal
Tildipirosin is a macrolide antimicrobial. It is authorised for the treatment and prevention of respiratory disease in cattle and pigs. There are no data on its administration in crocodiles. Therefore, this study evaluated the disposition kinetics of tildipirosin after intravenous (dose: 2 mg/kg) and intramuscular (doses: 2 and 4 mg/kg) administration ...

Thermoregulation in crocodilians—II. A telemetric study of body temperature in the Australian crocodiles, Crocodylus johnstoni and Crocodylus porosus

Comparative Biochemistry and Physiology Part A: Physiology, 1976
Abstract 1. Body temperature of Crocodylus johnstoni and C. porosus were recorded using radio telemetry. 2. Mean preferred temperature ranges were similar for both species, but those of C. johnstoni (31·3-32·5°C) were slightly lower than those found of C. porosus (32·0–33·1°C). 3. Little variation occurred in the mean daily body temperature.

PARAPHIMOSIS AND AMPUTATION IN A NILE CROCODILE (CROCODYLUS NILOTICUS)

Journal of Zoo and Wildlife Medicine, 2005
A captive Nile crocodile (Crocodylus niloticus) developed recurrent episodes of paraphimosis over a 2-yr period, which eventually led to hemorrhage and obvious inflammation. Two months postsurgery, the crocodile remained clinically normal.

Aeromonas hydrophila-Associated Septicemia in Captive Crocodiles (Crocodylus johnstoniandCrocodylus porosus)

Journal of Zoo and Wildlife Medicine, 2011
Five 25-yr-old crocodiles (Crocodylus johnstoni and Crocodylus porosus) were diagnosed with Aeromonas hydrophila-associated septicemia accelerated by improper thermoregulation. At necropsy, pulmonary congestion and pleural effusion were the main lesions in the thorax.

Cryopreservation of saltwater crocodile (Crocodylus porosus) spermatozoa

Reproduction, Fertility and Development, 2017
The aim of the present study was to develop a protocol for the successful cryopreservation of Saltwater crocodile spermatozoa. Sperm cells were frozen above liquid nitrogen vapour in phosphate-buffered saline (PBS) containing either 0.3 M trehalose, 0.3 M raffinose or 0.3 M sucrose and compared with glycerol (0.3–2.7 M).

Crocodylus moreletii in captivity

2017
This study documents results of the husbandry of Crocodylus moreletii in captivity, in cooperation with the Tiergarten Schönbrunn in Vienna. The first chapter reveals the incubation methods and proves that temperatures above 34°C in the first third of the incubation period will lead to abnormalities and even to the death of crocodile embryos, while ...

Bombesin-like immunoreactivity and the effect of bombesin in the gut, circulatory system and lung of the caiman, Caiman crocodylus crocodylus, and the crocodile, Crocodylus porosus.

Experimental biology, 1990
The presence of bombesin-like material in nerves and endocrine cells of the gastrointestinal canal, the circulatory system and the lung of the caiman, Caiman crocodylus crocodylus, has been investigated with immunohistochemistry (IHC) and radioimmunoassay (RIA).
