Flea diversity on small carnivores in the Northern Cape Province, South Africa

Small carnivores are parasitized by various ectoparasites that include fleas  (Siphonaptera). To date few parasite studies in South Africa, and especially the  Northern Cape, have focused on fleas, while those that have are biased by small sample sizes. In an attempt to address the paucity of information fleas were collected from five small carnivore species trapped at Loxton and Kimberley in the Northern Cape  Province, South Africa. The aim of the study was to contribute to current data on the flea diversity found on various small carnivore species. Small carnivores were trapped and while anesthetized the fleas were manually removed from the fur of the animals. In total 48 small carnivores were trapped of which 30 harboured fleas. Of the five flea species that were recorded the most numerous and prevalent was Echidnophaga  gallinacea followed by Ctenocephalides connatus and Ctenocephalides damarensis. Fleas were more numerous and prevalent on the small-spotted cat, Felis nigripes, followed by the yellow mongoose,  Cynictispenicillata. The flea community on the small carnivores consisted of fleas that prefer carnivores as principal hosts and also fleas that prefer rodents. The latter maybe acquired through predation on rodents.Key words: Siphonaptera, fleas, small carnivores, South Africa

Body condition scoring (BCS) in corn snakes (Pantherophis guttatus) and comparison to pre‐existing body condition index (BCI) for snakes

In the veterinary profession, the body condition score (BCS) plays an important role in the assessment of patients. It is a subjective, tactile method of evaluating body fat and muscle mass and is used in numerous species. Recognizing obesity (or the contrary, emaciation) is important for veterinarians treating reptiles and could be facilitated by a BCS. An existing form of body condition assessment already used is the body condition index (BCI), where the residuals from a regression of body mass on body length are calculated. Therefore, the goal of this study was to provide practitioners with a BCS system for corn snakes (Pantherophis guttatus) and to test it against the BCI. A total of 22 corn snakes (Pantherophis guttatus), stationed at the "Auffangstation für Reptilien" in Munich (reptile rescue centre, RRC), were subject of this study. Each had the following measurements taken: body weight (BW), snout-tail tip length (STL), snout-vent length (SVL) and circumference in the middle (C). Manual palpation of spine, area between vertebral spinous and transverse process, ribs and neck of each snake was performed by three veterinarians and assigned to specific scores by each examiner. A BCS (mean of examiners' scores) was given to each snake according to manual palpation. The BCS system was chosen to be out of 5 in 0.5-point steps with 2.5 considered as ideal BCS. In the studied snakes, the BCS ranged from 1.5 to 3.5, with a median of 2.5. The median BW was 309 g (75-967 g), the median STL was 123 cm (79-153 cm), the median SVL was 104 cm (73-133 cm) and the median C was 7.5 cm (4.3-11 cm). BCS and BCI were positively correlated. A BCS includes a manual palpation of the animal and thus gives the examiner additional information to the objectively measured/calculated index
