Testudinid herpesvirus infections in tortoises belonging to the Testudinidae family are well known for decades, but their pathogenesis remains poorly understood and treatments are often empirical. This study describes the in vitro evaluation of selected anti-herpesvirus compounds against Testudinid Herpesvirus 3 (THV-3). A-5021, a compound with known broad-spectrum anti-herpetic activity, showed to be 9 times more potent than acyclovir, with an EC50 of 13.2 µM and inducing a complete inhibition of viral replication at 37.7 µM. Initial pharmacokinetic parameters were determined after a single sub-cutaneous administration of 5 and 10 mg/kg in Hermann’s tortoises (Testudo hermanni, n=3). Blood samples were collected at different time points and plasma concentrations of A-5021 were determined. No adverse effects were clinically observed and plasma concentrations remained above the EC50 for 2.8 and 4.2 h after administration of 5 and 10 mg/kg, respectively. These preliminary data provide a basis for further proof-of-concept studies for a potential prophylactic or therapeutic treatment of THV-3 infection in tortoises [less ▲]

Failure to respond to commercial limited antigen diets can occur in dogs kept on a dietary trial for the diagnosis of adverse food reaction (AFR). The aim of this study was to assess twelve canine dry limited antigen diets (eleven novel protein diets and one hydrolysed diet) for potential contamination by ingredients of animal origin not mentioned on the label. The validity of the two methods adopted for the detection of such food antigens was also evaluated. Each dietary product was analysed by microscopy analysis using the official method described in Commission Regulation EC 152/2009 with the aim of identifying bone fragments of different zoological classes (mammalian, avian and fish) and by polymerase chain reaction (PCR) for the identification of DNA of animal origin. Discrepancies between the results obtained by PCR and/or microscopy analysis and the ingredients listed on pet food packages were found. Only in two pet foods did the results of both analyses match the ingredients listed on the label. In the remaining ten samples, microscopy detected bone fragments from one or two unpredicted zoological classes, revealing avian fragments in six of ten samples followed by those of fish in five of ten and mammalian fragments in four of ten. In two samples, microscopy analysis identified a contamination that would have otherwise passed unobserved if only PCR had been used. However, PCR confirmed the presence of all the zoological classes detected by microscopy and also identified the DNA of an additional unexpected zoological class in two samples. Dogs might fail to respond to commercial limited antigen diets because such diets are contaminated with potential allergens. Both PCR and microscopy analysis are required to guarantee the absence of undeclared animal sources in pet foods. Before ruling out AFR, a novel protein home-made diet should be considered if the dog is unresponsive to a commercial regimen. [less ▲]

The present study investigated the effects of bodyweight (BW) gain on respiratory function and airway responsiveness in healthy Beagles using barometric whole body plethysmography (BWBP). Six adult dogs were examined before and after a fattening diet. The high-energy diet induced a mean increase in BW of 41 ± 6%. BWBP basal parameters were recorded prior to airway reactivity testing (using increasing concentrations of histamine nebulisations). An airway responsiveness index (H-Penh300) was calculated as the histamine concentration necessary to reach 300% of basal enhanced pause (Penh, bronchoconstriction index). The same dogs underwent a doxapram hydrochloride (Dxp) stimulation testing 2 weeks later. Basal measurements showed that obese dogs had tidal volume per kg (TV/BW) that was significantly decreased whilst respiratory rate (RR) increased significantly. H-Penh300 decreased significantly in obese Beagles, indicating increased bronchoreactivity. Dxp administration induced a significant increase in TV/BW, minute volume per kg (MV/BW), peak inspiratory and expiratory flows per kg (PIF/BW and PEF/BW) in both normal and obese dogs although the TV/BW increase was significantly less marked in the obese group. In conclusion, obesity induced changes in basal respiratory parameters, increased bronchoreactivity and a blunted response to Dxp-induced respiratory stimulation. This combination of basal respiratory parameters, bronchoreactivity testing and pharmacological stimulation testing using non-invasive BWBP can help characterize pulmonary function and airway responsiveness in obese dogs.

The effects of the dietary inclusion of two levels of short-chain fructooligosaccharides (sc-FOS) on weight loss, biochemical parameters and serum haptoglobin concentration were investigated in twelve experimental obese Beagle dogs. Dogs were randomised into two groups and submitted to a weight loss program (WLP): the control group (C) received a commercial energy-restricted high-protein diet containing 1 % DM sc-FOS, whereas the test group (T) received the same diet enriched with sc-FOS to attain a 3 % DM content. Body weight (BW) and body condition score were weekly assessed in each dog and blood was collected before and after WLP to measure total plasma cholesterol (CHOL), TAG, NEFA, glucose (GLUC), insulin, serum leptin and haptoglobin. Groups showed similar BW and blood parameters before treatment. When values before and after treatment of the dogs were compared, significant reductions were observed for all parameters, with the exception of NEFA and GLUC. However, when these reductions were compared between C and T groups, significant differences were detected only for haptoglobin (T before v. T after: 1545 v. 605 mg/l, P = 0.03; C before v. C after: 1635 v. 1400 mg/l, P = NS). Positive correlations between haptoglobin and CHOL and between haptoglobin and TAG were observed before but not after WLP. In conclusion, feeding obese dogs with the energy-restricted diet caused significant weight loss and reduction of blood parameters, irrespective of the sc-FOS content included. However, serum haptoglobin level, and the subclinical inflammatory condition associated with it, was significantly lowered in the T but not in the C group. [less ▲]

Ferret's nutritional needs are not discussed, but practical feeding is controversial. The use of dry food is practical while feeding fresh meat or whole prey seems to be most adapted to the physiology of this animal. Dry foods contain carbohydrates in large quantities, while the ferret does not need it. Informations read on the labels do not give the source, quality or digestibility coefficients of the ingredients, so it is necessary to go into detail about commercial products. Dry foods should be of high quality, they should contain high protein and fat levels, low rates of nitrogen-free extract (calculated), and ingredients of animal origin should be at the head of the list. Fresh meat based food is an alternative and its use is already widespread in some countries. Frozen whole prey as day-old chicks or small rodents, are sold by specialized companies who provide zoo and carnivore’s owners. Meat based diets containing muscles, organs, bones, and other animal products may be an alternative to whole preys if they are balanced. The microbiological risk is greater than for dry food, but it remains low if basic principles of food safety are respected. Diseases such as dental disease, gastrointestinal diseases, insulinoma, urolithiasis, nutrient deficiencies and excesses, are diseases of the ferret that may have a nutritional origin. It is therefore important to focus on the choice of the diet for this animal. [less ▲]
