Phenotypic diversity and potential virulence factors of the Shewanella putrefaciens group isolated from freshwater fish

isolates collected from fish, whereas ATCC BAA-1097 isolated from sediment and ATCC 8071 collected from food products were classified to separate serological variants (VI and XI, respectively) ( Table 3 ). Over 70% of tested isolates were classified to one of the serological variants. The largest serological variant (II) contained 11% of the isolates, whereas variants VII, VIII, and X laid claim to 9% of the isolates each. Variants IV, V, XIII, and XIV were represented by single isolates. No cross reactivity between antigens of the other reference strains ATCC 7966, ATCC

Effects of dietary phytogenic product on the performance and immune response of pigs

Abstract

The aim of the study was to determine the effects of supplementation of sows’ and weaners’ diet with Stresomix, preparation containing extracts from Magnifera indica, Withania somnifera, Phyllanthus emblica, and Ocimum sanctum, on pig performance and immunity under field condition. The hypothesis was that anti-inflammatory, antistress, and immunomodulatory properties of the herbs would enhance production parameters and immune response, according to the manufacturer's claim. The study was performed on 16 sows and 160 piglets. The following parameters were recorded: concentration and proportion of white blood cells and their populations, concentration of serum immunoglobulins, specific humoral postvaccinal response after vaccination against swine influenza and swine erysipelas, and main production parameters. No significant differences among treatment groups were found with regard to concentrations of leukocyte subpopulations and immunoglobulins, as well as all investigated production parameters (P>0.05). In conclusion, the results of the study did not confirm that the investigated polyherbal product, administered at dose recommended by manufacturer, is able to significantly improve the performance and postvaccinal humoral response in clinically healthy pigs under field condition.

Review of animal models used to study effects of bee products on wound healing: findings and applications

Abstract

Non-healing wounds are associated with high morbidity and might greatly impact a patient’s well-being and economic status. For many years, scientific research has focused on developing and testing several natural and synthetic materials that enhance the rate of wound healing or eliminate healing complications. Honey has been used for thousands of years as a traditional remedy for many ailments. Recently, honey has reemerged as a promising wound care product especially for infected wounds and for wounds in diabetic patients. In addition to its proposed potent broad-spectrum antibacterial properties, honey has been claimed to promote wound healing by reducing wound hyperaemia, oedema, and exudate, and by stimulating angiogenesis, granulation tissue formation and epithelialisation. Several animal models, including large animals, dogs and cats, and different species of laboratory animals have been used to investigate the efficacy and safety of various natural and synthetic agents for wound healing enhancement. Interpreting the results obtained by these studies is, however, rather difficult and usually hampered by many limiting factors including great variation in types and origins of honey, the type of animal species used as models, the type of wounds, the number of animals, the number and type of controls, and variation in treatment protocols. In this article, we provide a comprehensive review of the most recent findings and applications of published experimental and clinical trials using honey as an agent for wound healing enhancement in different animal models.

New method of analysis of nitrofurans and nitrofuran metabolites in different biological matrices using UHPLC-MS/MS

due to safety not being possible to claim for any residue levels ( 4 – 6 ). However, the data from the Rapid Alert System for Food and Feed (RASFF) database for the years 2002 to 2017 showed 854 notification events reported for nitrofurans, indicating that contamination in various matrices is still present ( 12 ). The notifications referred to a wide range of products such as honey, feed and feed water, fish and aquaculture products, and meat and meat products ( 12 ). Many methods have been created for analysis of nitrofuran metabolites in biological matrices ( 8

Detection and molecular analysis of bovine enteric norovirus and nebovirus in Turkey

also bovine enteric caliciviruses associated with enteric diseases in calves ( 3 ), in the aetiology of which several reports claim noroviruses and neboviruses may play a role ( 18 ). In Turkey, bovine noroviruses were detected in diarrhoeic calves for the first time in 2011. Among 70 stool samples collected from calves, 6/70 (8.5%) samples were found to be positive in the Marmara region of Turkey ( 23 ). In another survey study, 4/235 (1.7%) samples were found to be positive for bovine norovirus in 2016 ( 7 ). There is no report of neboviruses in Turkey other than

Effect of TNF-α concentration on selected clinical parameters of swine after burns

Dehne et al . ( 9 ) claim that the concentration of IL-6 and IL-8 as well as TNF-α after burns in humans were dependent on the extent of those burns. Jeschke et al . ( 14 ) showed the correlation between the dynamics of TNF-α concentration increase and the extent of the burn, however, these results have not been confirmed by other authors ( 22 ). The majority of the authors agree that the TNF-α concentration increases after a burn injury, although some state that the concentration of TNF-α in human burn patients does not differ from the concentration in the control
