The lesser kestrel (Falco naumanni) is a small falcon with a Euro-Central and Asian-Mediterranean range wintering in sub-Saharan Africa. In the second half of the 20th century, the European population experienced a steep decline and was classified as at risk; thus, its biological and ecological aspects have been widely investigated. Nonetheless, data on hematology and plasma chemistry are not yet available. Therefore, hematology and biochemistry parameters were investigated in a sampling population of clinically healthy lesser kestrels (21 female and 10 male adults) from an Italian rescue center during breeding season, estimating the 95% (2.5 - 97.5th percentile) reference intervals (RI) for standard tests based on either parametric or robust statistical methods. The effect of sex on the referenced parameters was also tested and showed no statically significant differences. The established 95% RI highlighted values comparable with those of other similar raptors such as American kestrel (Falco sparverius) and peregrine falcon (Falco peregrinus). As the first recorded hematology and serum chemistry RI, these clinical data could support conservation efforts and clarify the effects of various environmental and ecological factors on the clinical and health status of lesser kestrels, although they should be reinforced with further data from healthy wild animals.

Although the red fox (Vulpes vulpes) is a widespread free-living species in Europe and is often treated as a patient in wildlife rescue centers, peer-reviewed published reference intervals (RI) for hematologic and biochemistry variables are not available. The aim of this study was to determine routine RI for common clinical analyses for this species. After rescue events, single blood samples were collected from 14 female and 18 male adult red foxes and submitted for standard hematologic and biochemistry analyses. The RI were determined by either parametric (normally distributed data) or robust (nonnormal data) statistical methods and showed values close to those reported for specimens of similar fox species, but they were not comparable to historical veterinary clinical data gathered from animals following surgeries or pathology sample collections. Sex did not significantly affect the blood variables, except for iron, which was higher in males. This is the first study reporting RI for a large number of blood analytes in free-living red foxes in Italy. The proposed hematologic and serum chemistry RI, which are specific to red foxes that have recovered after veterinary treatments, represent a set of healthy clinical values that will be helpful for both veterinary care and environmental monitoring.

The goal of this study was to establish routine reference intervals (RI) for common laboratory tests for the European badger (Meles meles). Blood samples were collected from 13 female and 11 male adult European badgers in a wildlife rehabilitation facility and used for standard hematology and biochemistry analyses. The established 95% RI (2.5th-97.5th percentile) were determined by either parametric (normally distributed data) or robust (nonnormal data) statistical methods and showed a lower range of variability compared with those reported in previous literature. Sex did not affect any investigated parameters. As the first RI study on free-living European badgers in Italy, these reported hematology and serum chemistry RI provide a set of accurate and reliable laboratory parameters for this species.

This study aimed to investigate how three groups of people of differing ages, and with differing knowledge of the species, perceived the emotional state of African elephants (Loxodonta africana) managed in captive and semi-captive environments. Fifteen video-clips of 18 elephants, observed during three different daily routines (release from and return to the night boma; interactions with visitors), were used for a free choice profiling assessment (FCP) and then analyzed with quantitative methods. A general Procrustes analysis identified two main descriptive dimensions of elephant behavioral expression explaining 27% and 19% of the variability in the children group, 19% and 23.7% in adults, and 21.8% and 17% in the expert group. All the descriptors the observers came up with showed a low level of correlation on the identified dimensions. All three observers' groups showed a degree of separation between captive and semi-captive management. Spearman analyses showed that stereotypic "trunk swirling" behavior correlated negatively with first dimension (free/friendly versus sad/bored) in the children's group; second dimension (agitated/confident versus angry/bored) amongst the adults; and first dimension (active/excited versus agitated/bored) amongst the experts. More studies are needed to investigate other potential differences in assessing elephants' emotional states by visitors of different ages and backgrounds.

The aim of this study was to investigate fetal gastrointestinal motility (FGM) of dogs using ultrasonic imaging and its association with vaginal and rectal temperature, serum progesterone concentrations and fetal heart rate. Pregnant bitches were examined after day 54 of gestation and there were determinations of vaginal and rectal temperature and serum progesterone concentrations. The fetal abdomen was evaluated for 30 s using longitudinal and transversal assessments, and FGM was scored as 0 (no peristalsis) or 1 (evident peristalsis). Number of fetuses with a 1 or 0 score were determined for each bitch (number and the percentage of fetuses with FGM). A total of 135 FGM measurements were recorded. There was FGM in 0/3, 0/6, 1/6 (16.7 %), 3/20 (15 %), 5/18 (27.3 %), 18/28 (64.3 %), 12/17 (70.6 %), 14/22 (63.6 %), 6/9 (66.7 %), 4/6 (66.7 %) fetuses from day -9 until 0 preceding parturition, respectively. In the last 5 days before parturition, 63.3 % of fetuses had FGM. Vaginal and rectal temperature were strongly and positively correlated (P < 0.001). Vaginal temperature was positively correlated with progesterone concentrations and fetal heart rate (P < 0.01), and there was a small negative correlation with FGM (r = - 0.331, P < 0.05). Due to ease of data collection, the assessment of FGM is a valuable procedure for evaluation of fetal maturity in dogs. Vaginal and rectal temperatures are reliable variables to be assessed during the last week of pregnancy for estimating the time of parturition.

Fusarium spp. are pathogens plants, animals and humans, isolated from soil, plants and water systems. They are distributed worldwide and include saprotrophic, biotrophic‑pathogenic or endophytic fungi, or producers of mycotoxins (fumonisins). Human isolates are becoming the leading mycosis affecting immunocompromised patients and frequently involved in mycoses of aquatic mammals and reptiles, included sea turtles or their eggs. Here reported are three severe cases of unusual localizations of Fusarium in loggerhead sea turtle (Caretta caretta) and their diagnostic, therapeutic and clinical output. In the clinical practice, correct genus‑level identification of Fusarium species is critically important to enable correct treatment as in vitroantifungal susceptibility testing is mandatory for each Fusarium‑like isolate. For this reason, susceptibility testing can significantly help the practitioner in choosing the most appropriate therapeutic protocol.

Fluoroquinolone antibacterial drugs are currently used in reptilian medicine because of their broad spectrum of activity including the most frequent pathogens of these species. The disposition kinetics of marbofloxacin (MBX) at a single dose of 2 mg/kg were determined in healthy red-eared sliders after intravenous (IV) and intramuscular (IM) administration. The influence of renal portal system on the bioavailability of the drug was investigated by using forelimb and hindlimb as IM injection sites. Apparent volume of distribution at steady-state (Vss ) and systemic clearance (Cl) of marbofloxacin after IV administration were estimated to be 48.21 ± 5.42 ml/kg and 23.38 ± 2.90 ml/hr·kg, respectively. The absolute bioavailabilities after IM route were 45.96% (forelimb) and 52.09% (hindlimb). The lack of statistically significant differences in most of the pharmacokinetic parameters after the two IM injection sites suggests a negligible influence of renal portal system in clinical use of MBX, although the Cmax after IMfore administration is advantageous, having into account the concentration-dependent action of this antibiotic. The absence of visible adverse reactions in the animals and the advantageous pharmacokinetic properties suggest the possibility of its safe and effective clinical use in red-eared sliders.

GnRH-agonist implants are currently marketed in Europe for use in male dogs but their off label use in female dogs, cats as well as other wild or semidomesticated animals is becoming increasingly popular. Implanted females frequently show a fertile heat after treatment, but the ensuing pregnancy may end spontaneously due to hormonal suppression at the hypothalamic level. This report describes the case of a jill treated with a 4.7 mg deslorelin implant in order to control her cyclicity. A few weeks later she was found to be pregnant and subsequently gave birth to 6 kits. The deslorelin implant did not affect fetal health or pregnancy duration. However, despite normal mammary development with milk production, the jill did not show adequate maternal instinct and did not take adequate care of her kits, 5 of which died during the following weeks. This is the first report of a normal pregnancy following administration of a deslorelin implant in a ferret.

The European hedgehogs may require the use of chemical restraint for clinical examination because of their tendency to roll up as a defensive behaviour. This study evaluated the effects of alfaxalone combined with dexmedetomidine for restraint of hedgehogs undergoing pre-release health checks and atipamezole for recovery. Twenty hedgehogs received alfaxalone 2 mg/kg and dexmedetomidine 0.05 mg/kg intramuscularly in the quadriceps. If the righting reflex was still present, both drugs were administered at half of the initial doses. A semiquantitative scale scored sedation; clinical variables evaluated included pulse rate, respiratory rate, arterial haemoglobin oxygen saturation, end-tidal CO2 and body temperature. The righting reflex disappeared between 141 and 880 seconds. Overweight animals required one additional injection to achieve adequate relaxation. Pulse rate decreased during the procedure and increased after atipamezole administration. Respiratory rate and end-tidal CO2 did not change statistically throughout the procedure but one hedgehog showed haemoglobin oxygen saturation lower than 90%. Recovery after atipamezole was smooth and complete. Body temperature decreased over time. The sedation protocol may represent an effective combination to restrain European hedgehogs and atipamezole provides a rapid antagonism. Additional sedatives administration may be required in overweight animals and an external source of oxygen should be available.

Objectives The purpose of this study was to assess efficacy of deslorelin, a gonadotropin-releasing hormone (GnRH) agonist marketed in Europe for the control of male dog reproduction, for the postponement of puberty in queens. Methods Nine prepubertal queens aged 3–9 months were selected for this study; their general and reproductive health was checked through clinical, haematological, vaginal cytology and hormonal tests. Following treatment with a 4.7 mg deslorelin implant, each cat received a monthly clinical examination and blood was collected for hormonal assay every third month. Cats were monitored for 14.1 ± 5.2 (range 7–23) months. Results All cats were in good body condition and normal health prior to treatment. Their health status remained unchanged throughout the study and no significant variation was observed with regard to serum progesterone or oestradiol. Seven days post-treatment, 1/9 queens showed signs of heat, and one other queen showed complete vaginal keratinisation. No other signs of heat were subsequently observed in any other queen. Five queens were lost during the study after 7, 7, 16, 17 and 18 months of observation (during which time they did not show signs of heat). By the end of the study, no sign of puberty was observed in the four remaining queens at 21–36 months of age. Conclusions and relevance A 4.7 mg deslorelin implant was able to suppress the feline pituitary–gonadal axis, leading to postponement of puberty for up to 21–36 months in the four queens that completed the study. Deslorelin can be considered as a safe method to postpone puberty in queens.

Encephalitozoon cuniculi is a parasite that can infect a variety of animals, including immune-compromised humans. Rabbits are prone to encephalitozoonosis but the subclinical course and high serum prevalence make it difficult to diagnose with certainty in live animals. Different approaches have been used to support the presence of an active infection in symptomatic rabbits: antibodies titers, IgM and IgG serum evaluation, electrophoresis, PCR in urine, and cerebrospinal fluid analysis. In this study, 76 symptomatic rabbits were divided in three groups based on their Ig results: IgM+ IgG+, IgM-IgG+ and IgM-IgG-. By statistical analysis total serum protein was proved not to be effective in predicting an antibody response, in contrast the γ-globulin ranges from serum electrophoresis can predict whether the patient is positive for IgM and/or IgG. In fact, a significant quantitative correlation between percentage of γ-globulins and positive IgM and IgG serum for E. cuniculi was established in symptomatic rabbit. These values can be useful to perform a screening both for symptomatic and asymptomatic rabbits.

ABSTRACT In migratory species female‐ and male‐mediated gene flow are important for defining relevant Management Units, and for evaluating connectivity between these and their respective foraging grounds. The stock composition at five Mediterranean foraging areas was investigated by analysing variation in the mitochondrial D‐loop and six microsatellite loci in a sample of 268 loggerhead turtles ( Caretta caretta ) stranded or accidentally caught by fisheries. This involved a comprehensive Mixed Stock Analysis which considers also recent data from major rookeries in Libya and Turkey, and the generation of a standardized nomenclature of allele sizes at the microsatellite loci. The results indicate: that the north Adriatic, the Tunisian continental shelf, the waters around Malta and the Italian Ionian Sea represent important areas for the conservation of rookeries in Greece, Libya and Turkey, respectively; that waters off the Italian peninsula and the islands of Lampedusa and Malta are mainly inhabited by individuals of Mediterranean origin, with a major contribution from the nearest and largest colonies, while Atlantic turtles are restricted to the western areas; that specific migratory routes exist from rookeries to foraging grounds; a poor bi‐parental genetic structuring, which suggests a high male‐mediated gene flow in the Mediterranean; mixing of small turtles in waters distant from natal rookeries, and recovery of structuring for large‐sized individuals; and that uncommon mtDNA haplotypes are more powerful markers than microsatellite alleles in assessing an individual's origin, owing to their higher geographic specificity.

A 20-yr-old African fur seal (Arctocephalus pusillus) presented with a slowly growing mass located on the dorsum at the level of the last thoracic vertebrae. The mass was hard, 10 cm in diameter, and not adherent to the underlying tissues. Multiple biopsies were collected for histopathology and revealed extensive areas of necrosis, small nodules of malignant mesenchymal proliferation with areas of chondroid metaplasia, and atypical cells in vessel walls. The morphologic diagnosis was suggestive of malignant mesenchymal neoplasia originating from the vascular wall. The mass was removed 1 mo later due to ulceration and infection. Histologically, based on the World Health Organization's classification of neoplastic processes in domestic animals, the tumor was consistent with malignant mesenchymoma. The margins of resection revealed the presence of neoplastic cells. Based on these results, the particular species involved, the high local invasiveness, and the high metastatic index of this malignant tumor in domestic mammals and humans, the prognosis was poor. The animal died 6 mo later with metatastic disease.

The aim of this study was to investigate the prevalence of behavioral complaints in rabbits, mustelids, and rodents that were kept as pets, to help veterinary practitioners while counseling prospective owners toward an informed and responsible choice of a pet. A total of 193 owners participated in the study, filling in a questionnaire, for a total of 371 pets (184 rabbits, 59 mustelids, 128 rodents). The prevalence reported by owners of behavioral complaints was 31.3% (29.3%, 52.5%, and 20.3% for rabbits, mustelids, and rodents, respectively; χ2 = 19.6; P < 0.001). Aggression toward people was reported in 13.2% of the sample (13.0%, 30.5%, and 5.5% for rabbits, mustelids, and rodents, respectively; χ2 = 9.4; P = 0.009). Stereotypic behavioral patterns were reported by owners in 26.4% of the cases (28.3%, 16.9%, and 28.1% for rabbits, mustelids, and rodents, respectively). The owners reported that the prevalence of stereotypies was higher in pets housed more restrictively (Fisher’s exact test; P < 0.001). The overall level of satisfaction was quite high (i.e., 8.6 ± 1.84 points out of 10), but was lower in pets declared to have unwanted behavioral patterns (P < 0.05).

Chemical immobilization of free-ranging and captive wildlife is often required in many clinical situations. In this trial, tiletamine-zolazepam was combined with the alpha2-agonist, detomidine, in order to use the least amount of anesthetic drug possible to achieve a rapid immobilization; to ensure safety for animals and operators; and to be easily reversible with specific antagonists for a fast recovery. Twelve captive Asiatic black bears were anesthetized for clinical procedures, including clinical examination and blood sample collection, and for electrocardiographic and echocardiographic procedures. The combination detomidine-tiletamine-zolazepam, at the dosages of 0.03 mg/kg for detomidine and 1.5 mg/kg for tiletamine-zolazepam, proved to be reliable and effective in immobilizing Asiatic black bears for a 1-hr handling period for routine clinical procedures. Minimal or no respiratory and/or cardiopulmonary adverse side effects were observed, even with dosages calculated on the basis of an estimated body weight. The respiratory rate, pulse rate, and hemoglobin-oxygen saturation remained stable for the entire duration of anesthesia. Cardiac rhythm was always sinusal in all animals. Small injection volumes and darts for blowpipe use were utilized to minimize tissue damage at the site of injection. Induction and recovery were smooth and predictable, and provided for the safety of operators who could observe the bears' activities from a safe distance. Furthermore, the availability of the alpha2-antagonist atipamezole to counteract the effects of detomidine made this anesthetic regimen easily controllable and reversible. Moreover, the recovery time can be shortened by intravenous administration of this antagonist drug.
