Zoonoses and potential zoonoses of bears

Captive and free‐ranging wild bears can carry and transmit several zoonotic pathogens. A review of nearly 90 years of scientific publications concerning confirmed and potential zoonotic diseases that can be present in any of the eight species of bears in the world was conducted. The findings were organized amongst the following disease sections: bacterial, viral, protozoal, mycotic, helminth and arthropod‐borne. The most commonly reported pathogens of concern were of parasitic (Trichinella, Toxoplasma) and bacterial (Francisella, Brucella) origin.     

The interaction between microbiome and pig efficiency: A review

The existence of genetic control over the abundance of particular taxa and the link of these to energy balance and growth has been documented in model organisms and humans as well as several livestock species. Preliminary evidence of the same mechanisms is currently under investigation in pigs. Future research should expand these results and elicit the extent of genetic control of the gut microbiome population in swine and its relationship with growth efficiency. The quest for a more efficient pig at the interface between the host and its metagenome rests on the central hypothesis that the gut microbiome is an essential component of the variability of growth in all living organisms. Swine do not escape this general rule, and the identification of the significance of the interaction between host and its gut microbiota in the growth process could be a game-changer in the achievement of sustainable and efficient lean meat production. Standard sampling protocols, sequencing techniques, bioinformatic pipelines and methods of analysis will be paramount for the portability of results across experiments and populations. Likewise, characterizing and accounting for temporal and spatial variability will be a necessary step if microbiome is to be utilized routinely as an aid to selection.     

Morphology of the Atlantic salmon (Salmo salar) tongue

The Atlantic salmon (Salmo salar) is a freshwater and marine fish of the family Salmonidae, widely farmed in aquaculture facilities in several countries. The salmon are carnivorous, but in aquaculture, alternative foods have been experienced. It is well known that feeding in captivity should cause adaptation and modifications of the morphological characteristics of the oral cavity, especially of tongue; therefore, the aim of this study was to investigate, by light, laser confocal and scanning electron microscopy, the morphological characteristics of the tongue dorsal surface, considering the importance of the correlations between feeding habits and the anatomy of the tongue. Scanning electron microscopy demonstrates the presence of caniniform teeth with oro-aboral orientation surrounded by numerous filiform papillae, single, fused or arranged in row. Oro-aborally, the papillae show an appearance like a rosette and they disappear at level of the root. Light and laser confocal microscopy demonstrates that the mucosa is covered by a non-keratinized stratified pavement epithelium with, in the deepest layer, the presence of a triangular structure whose apex is cranially directed and base facing aborally. In this structure, spindle-shaped cells are present, with a vimentin immunoreactivity, that for their characteristics could be adult mesenchymal stem cells. The obtained data could be useful not only for further studies on the nutrition, but it is interesting the detection of tissues typical of the embryo-fetal phase in the adult specimens tongue, thus giving a basis for studies of potential applications, if any, regarding cell therapies for different clinical indications.     

紫苏叶提取物对高脂血症家兔血脂及脂质过氧化的影响（英文）

[Objective] The preventive and therapeutic effects of Folium perillae extract(FPE)on hyperlipemia induced by feeding rabbit with high fat forage were observed.[Method] The high fat and cholesterol diet were adopted to create the hyperlipemia model of rabbit.The rabbits were randomly and equally divided into 5 groups which were NC(normal control)group,HLM(high lipid model)group,LFPE,MFPE and HFPE group(low,middle,high dosage of FPE were 0.17 g/kg,0.5 g/kg and 1.5 g/kg respectively).The contents of TC,TG,LDL-C,HDL-C,MDA and the activity of SOD in serum were detected respectively.[Result] The three FPE groups could decrease the contents of TC,TG,LDL-C,MDA significantly(P<0.01)compared with these of HLM group,and the contents of HDL-C(P<0.01))and the activity of SOD(P<0.05)in serum was increased significantly.[Conclusion] FPE could regulate blood-fat and counteract lipid peroxidation.
