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 ...

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 ...

Poxvirus infection in Nile crocodiles (Crocodylus niloticus)

Research in Veterinary Science, 1990
An outbreak was encountered of numerous yellowish cutaneous nodules in one- to two-year-old farmed Nile crocodiles (Crocodylus niloticus) in Kasaba Bay Crocodile Farm at Lake Tanganyika in Zambia during 1988. Out of 4000 crocodiles of different age groups, 300 yearlings were affected and 82 of those affected died. The lesions were prominent on the head,

Evolutionary history of Cuban crocodiles Crocodylus rhombifer and Crocodylus acutus inferred from multilocus markers

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2011
AbstractAmong crocodilians, Crocodylus rhombifer is one of the world's most endangered species with the smallest natural distribution. In Cuba, this endemic species coexists with the American crocodile (Crocodylus acutus). Hybridization between these two species is well known in captivity and might occur in the wild, but has never been demonstrated ...

Nile crocodiles, Crocodylus niloticus, and estuarine crocodiles, Crocodylus porosus, show similar osmoregulatory responses on exposure to seawater

Comparative Biochemistry and Physiology Part A: Physiology, 1988
1. Nile crocodiles, reared in fresh water and exposed acutely to seawater, suffer marked dehydration and hypernatraemia. Cloacal urine osmolarity and potassium concentration increased markedly but urine sodium remains low. 2. Hypernatraemia is increased when secretion from the lingual salt glands is prevented. 3. C.

Hybridization between Crocodylus acutus and Crocodylus moreletii in the Yucatan Peninsula: II. evidence from microsatellites

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2008
AbstractDetecting and quantifying hybridization between endangered or threatened taxa can provide valuable information with regards to conservation and management strategies. Hybridization between members of the genus Crocodylus has been known to occur in captivity and in some wild populations.

Detection of Crocodylus mindorensis x Crocodylus porosus (Crocodylidae) hybrids in a Philippine crocodile systematics analysis

Zootaxa, 2012
The Philippine crocodile (Crocodylus mindorensis) is considered one of the most endangered of the crocodilian species.Rumors or anecdotal concerns have existed for some time as to the possibility of hybrid individuals existing in a captivecollection under consideration for providing reintroduction candidates; however, visual observations failed to ...

Patterns of Metabolic Rate in Embryonic CrocodiliansCrocodylus johnstoniandCrocodylus porosus

Physiological Zoology, 1990
The metabolic rate of Crocodylus johnstoni eggs was measured through incubation at 29° and 31° C, and in C. porosus eggs at 30° C. The pattern of metabolic rate in both species ispeaked, similar to patterns recorded in other embryonic reptiles that develop in hard:shelled (cleidoic) eggs. Maximum $\dot{V}_{O_{2}}$ occurs when incubation is less than 90%

Wariness in Crocodylus porosus (Reptilia : Crocodilidae)

Wildlife Research, 1979
Of 1364 C. porosus sighted at night, 954 (69.9%) could be approached by a boat and spotlight to within 5 ft, and 1191 (87.3%) to within 20 ft. The percentage which could be approached to within 5 ft decreased with increasing body size and varied between rivers.
