The objetive of this study was to compare a single dose of secnidazole versus multiple doses of fenbendazole for the treatment of dogs with asymptomatic Giardia infection. Materials and methods: Twenty-four asymptomatic dogs with a positive test result for Giardia spp were randomized in two equal groups to receive a single dose of secnidazole at 30 mg/kg PO, or fenbendazole at 50 mg/ kg PO q24h for 3 days. Hematological parameters were evaluated before and 8 days after treatment, and feces were re-examined at days 8, 15, and 30 post-treatment by fecal flotation and antigen test. Results: The number of positive dogs in the fenbendazole group was: 1 (day 8) and 3 (days 15 and 30). In the secnidazole group, the number of positive cases were: 4 (day 8), 3 (day 15), and 1 (day 30).  Conclusion: Treatment with secnidazole or fenbendazole, were effective between 75% and 92% to eliminate the excretion of Giardia cysts in canines together with hygienic measures to control, like disinfection with quaternary ammonium of patients and their environment. Further studies that include more animals and multiple fecal exams on consecutive days would be necessary to confirm its efficacy in dogs.
本研究的目的是比较单剂量塞克硝唑和多剂量芬苯达唑对无症状贾第鞭毛虫感染狗的治疗效果。材料与方法:将24只贾第鞭毛虫阳性无症状犬随机分为两组,分别给予单剂量塞克硝唑(30 mg/kg PO)或芬苯达唑(50 mg/kg PO), q24h,连续3 d。在治疗前和治疗后8天评估血液学参数,并于治疗后8、15、30天通过粪便浮选和抗原检测重新检查粪便。结果:芬苯达唑组阳性犬数为:1只(第8天)、3只(第15、30天)。塞克硝唑组阳性病例数为:4例(第8天)、3例(第15天)、1例(第30天)。结论:塞硝唑或芬苯达唑治疗犬贾第鞭毛虫囊的排泄率在75% ~ 92%之间,同时采取季铵消毒等卫生措施加以控制。进一步的研究需要包括更多的动物和连续几天的多次粪便检查,以确认其对狗的有效性。

EFSA released the 89-page Scientific Opinion “Evaluation of the health risks related to the presence of cyanogenic glycosides in foods other than raw apricot kernels”. This opinion, and the ensuring media coverage, has left uncertainty in the minds of consumers, feed and supplement manufacturers and flaxseed producers of how much ground flaxseed can safely be consumed without crossing the threshold of cyanide toxicity. This editorial updates the science and tries to bring clarity to the question “how much flaxseed can I safely feed my dog, cat, horse on a daily basis?” and “how much can I safely eat?” The great majority of ground flaxseed products have a cyanogenic glycoside content of less than 200 mg / kg seed. For people, consuming 30 grams of such flaxseed the average peak blood cyanide concentration will be about 5 µmole / L, much less than the toxic threshold value of 20 to 40 µmole / L favoured by EFSA.  Thus, as much as 120 grams of crushed / ground flaxseed can be consumed by a 70 kg adult person before a toxic threshold of 40 µmole / L is reached (up to 1.7 grams ground flaxseed / kg body weight). The toxic threshold of cyanide for dogs is 2 to 4-fold greater than for humans, and unknown for cats and horses. The daily serving amounts for dogs and cats are about 0.23 grams / kg body mass per day, which will result in blood cyanide well below the toxic threshold. The highest recommended daily serving amount for horses is 454 grams per day, or 0.8 to 2 grams per kg / body mass depending on mass of the horse. This amount for horses should not be exceeded.
欧洲食品安全局发布了一份长达89页的科学意见,题为“对除生杏仁外的食品中氰苷存在的健康风险进行评估”。这一观点以及媒体的持续报道,给消费者、饲料和补充剂制造商以及亚麻籽生产商留下了不确定性,即在不超过氰化物毒性阈值的情况下,可以安全食用多少亚麻籽粉。这篇社论更新了科学,并试图澄清“我每天可以安全地给我的狗、猫、马喂多少亚麻籽?”和“我能安全吃多少?”绝大多数亚麻籽制品的氰苷含量低于200毫克/公斤种子。对于人来说,食用30克这样的亚麻籽,血液氰化物浓度的平均峰值约为5 μ mol / L,远低于欧洲食品安全局推荐的20 - 40 μ mol / L的毒性阈值。因此,一个70公斤的成年人在达到40 μ mol / L的毒性阈值(高达1.7克亚麻籽/公斤体重)之前,可以食用多达120克粉碎/磨碎的亚麻籽。氰化物对狗的毒性阈值是人类的2到4倍,对猫和马的毒性阈值则未知。狗和猫每天摄入的氰化物约为每公斤体重0.23克,这将导致血液中的氰化物远低于有毒阈值。马的最高推荐每日摄入量为每天454克,或每公斤体重0.8至2克,具体取决于马的质量。马匹不应超过这个数量。

The influence of essential oils (EOs) on emotions has been widely described among humans and animals. Several studies have investigated the effects and the actions of EOs on behaviour, mood and perception. In this study, shelter dogs (n=23) were exposed to olfactory stimulation through diffusion of 9 anxiolytic essential oils in one blend (olfactory enrichment) for 8 weeks in order to check long-term effects on behaviour. First, dog’s postures have been evaluated in both groups before and after exposure. Secondly, in order to collect the preliminary results on the distance necessary to obtain an effect of EOs, dogs were divided in 2 groups according to the distance from the diffuser. Our results indicate that olfactory enrichment with this blend of EOs is related to less time spent by dogs in high posture. More research is needed to investigate a potential gradual effect of distance and concentration of EOs on dog’s welfare. 
精油(EOs)对情绪的影响在人类和动物中得到了广泛的描述。一些研究调查了情绪对行为、情绪和感知的影响和作用。在这项研究中,收容所的狗(n=23)在8周的时间里,通过在一种混合物中扩散9种抗焦虑精油(嗅觉富集)来暴露于嗅觉刺激下,以检查对行为的长期影响。首先,对两组狗在暴露前后的姿势进行了评估。其次,为了收集获得EOs效果所需距离的初步结果,根据犬与扩散器的距离将犬分为两组。我们的研究结果表明,这种EOs混合物的嗅觉增强与狗保持高姿势的时间减少有关。需要更多的研究来调查EOs的距离和浓度对狗的福利的潜在逐渐影响。

The major histocompatibility complex (MHC) is an organized cluster of tightly linked genes, present in all vertebrates, playing an important role in the immune system, except the jawless fish [1]. MHC was first identified during tissue transplantation studies in mice [2] and was first known for its role in histocompatibility. Consequently, the role of MHC was discovered in immune regulation [3] and several other functions [4,5]. The important function of the MHC is to code for specialized antigen-presenting receptor glycoproteins, also called as MHC molecules. The products of these genes are involved in the induction and regulation of immune response. These molecules bind processed peptide antigens and present them to T-lymphocytes, thereby triggering immune response.
主要组织相容性复合体(MHC)是一组紧密相连的基因,存在于所有脊椎动物中,在免疫系统中发挥重要作用,但无颌鱼除外[1]。MHC最初是在小鼠组织移植研究中发现的[2],并首先因其在组织相容性中的作用而为人所知。因此,MHC在免疫调节中的作用被发现[3]和其他一些功能[4,5]。MHC的重要功能是编码特殊的抗原呈递受体糖蛋白,也称为MHC分子。这些基因的产物参与免疫反应的诱导和调节。这些分子结合加工过的肽抗原并将其呈递给t淋巴细胞,从而引发免疫反应。

The most significant pollutants are the heavy metals in the aquatic network due to their toxicity, accumulation, and bio-magnification. In an attempt to characterize the physical-chemical and demonstrate the potential water impact of the heavy metal content of wastes in two lakes in Sharkia province, Egypt, this study was developed to determine their toxicity and the potential waste impacts in biochemistry and histology of fish muscle. Samples of water and fish muscles were collected and analyzed for heavy metals using atomic absorption of two different fish species (Oreochromis niloticus and Clarias gariepinus) along two canals in Sharkia province in Egypt during the four seasons in 2018. The water samples were also analyzed for the physicochemical parameters. The impact of heavy metal on the enzymatic antioxidant (superoxide dismutase and catalase) as well as the reduced glutathione content, besides the oxidative stress marker presented by lipid peroxidation levels in fish muscles, were evaluated. Results showed the largest amount of chloride (Cl-) and iron (Fe) in the Sharkia water sample, while Faquas water sample had the highest level of HCO3 and iron (Fe). The manganese concentration in the fish muscle was the highest in Sharkia water and the highest level of Fe was detected in the fish muscles collected from Faquas area. These high levels of some of the physicochemical parameters and heavy metals in the two lakes with two different wastes as seen in this study may be a source of water pollution. The highest accumulation of metals in the muscle of the two fish species, suggesting risk for human consumption. There were seasonal variations in the level of LPO in muscle tissue of two types of fishes with a reverse relationship with antioxidant parameters. This accumulation varied seasonal and spatial as well as according to the species of fish. Increasing the level of heavy metals effect on the biochemistry and histology of fish.Keywords: Heavy metals; Muscle; Oxidative/Antioxidant, Histology, Clarias gariepinus; Oreochromis niloticus
水体网络中最重要的污染物是重金属,其毒性、蓄积性和生物放大性是主要的污染物。为了描述埃及Sharkia省两个湖泊废物中重金属含量的物理化学特征和潜在的水影响,本研究旨在确定它们的毒性和潜在的废物对鱼肌肉生物化学和组织学的影响。在2018年的四个季节,利用埃及Sharkia省两条运河上两种不同鱼类(Oreochromis niloticus和Clarias gariepinus)的原子吸收,收集了水和鱼肌肉样本,并分析了重金属。并对水样进行了理化参数分析。研究了重金属对鱼类肌肉中酶促抗氧化剂(超氧化物歧化酶和过氧化氢酶)、还原性谷胱甘肽含量的影响,以及通过脂质过氧化水平表征的氧化应激标志物。结果表明,Sharkia水样中氯化物(Cl-)和铁(Fe)含量最多,Faquas水样中HCO3和铁(Fe)含量最高。鱼类肌肉中锰的含量在Sharkia水域最高,而铁的含量在Faquas地区的鱼类肌肉中最高。这些高水平的物理化学参数和重金属在两个湖泊与两种不同的废物的研究中看到,可能是水污染的来源。这两种鱼类的肌肉中金属含量最高,表明人类有食用的风险。两种鱼类肌肉组织中LPO含量存在季节变化,且与抗氧化参数呈反比关系。这种积累随季节和空间以及鱼类种类的不同而变化。提高重金属水平对鱼类生物化学和组织学的影响。关键词:重金属;肌肉;氧化/抗氧化,组织学,Clarias gariepinus;Oreochromis niloticus

In order to evaluate condensed tannins (CT) effect on dairy goat gastrointestinal nematodes (GIN) under a grazing and confined systems, two experiments (E1 and E2) were made. On both, goats were kept in two groups of 10 animals each. Groups were: control, without treatment (CG) and CT supplemented (CTG) daily with 25 g (1,25%) in E1 and 75 g (2%) in E2. During the E1, feeding was based on Lucerne (Medicago sativa) grazing and supplementation with 500 g of corn grain and during the E2, stabled milking goats ate 500 g of corn grain and ad libitum lucerne hay. Biweekly, faecal egg counts (FEC) and coprocultures were made. In addition, FAMACHA© technique, body condition score (BCSS) and ingested food were recorded each two weeks during the 90 days (E1) and 76 (E2) days of trial. The FEC values in most of the study were low and no significant differences (p<0.78) were detected between groups. Mean FEC were 534 (CTG) and 357 (CG) during E1 and 509 (CTG) and 484 (CG) during E2. The predominant NGI genera were Trichostrongylussp. (48.1%), Haemonchus sp. (39.9%) and Teladorsagia sp. (12.0%). FAMACHA© scores did not show significant (p<0.41) differences between groups, but the CG (median=3) showed a BCS significantly (p<0.05) higher than those of CTG (median=2.5). The average milk production did not present statistically significant differences between groups (p<0.57), between sampling dates (p<0.23) and group x sampling dates (p<0.65). Under the conditions of these studies 25g or 75 g of CT in the diet had no anthelmintic or productive effects.Keywords: Gastrointestinal nematode; Dairy goat; Condensed tannin; Production
为评价浓缩单宁(CT)在放牧和封闭条件下对奶山羊胃肠道线虫(GIN)的影响,进行了E1和E2两个试验。在两个实验中,山羊被分成两组,每组10只。各组分别为:对照组、不治疗组(CG)和每日添加CT组(CTG), E1组25 g (1,25%), E2组75 g(2%)。E1期以苜蓿(Medicago sativa)放牧为基础,补充500 g玉米粒;E2期以玉米粒和苜蓿干草为基础,随意饲喂500 g。每两周进行粪卵计数(FEC)和共培养。在试验90 d (E1)和76 d (E2)期间,每两周记录一次FAMACHA©技术、体况评分(BCSS)和摄食量。大多数研究的FEC值较低,组间差异无统计学意义(p<0.78)。E1期平均FEC为534 (CTG)和357 (CG), E2期平均FEC为509 (CTG)和484 (CG)。主要的NGI属为毛线虫属。(48.1%)、Haemonchus sp(39.9%)和Teladorsagia sp(12.0%)。FAMACHA©评分组间差异无统计学意义(p<0.41),但CG组(中位数=3)的BCS显著高于CTG组(中位数=2.5)(p<0.05)。平均产奶量组间差异无统计学意义(p<0.57),采样日期组间差异无统计学意义(p<0.23), x组采样日期组间差异无统计学意义(p<0.65)。在这些研究的条件下,饮食中25克或75克的CT没有驱虫或生产作用。关键词:胃肠道线虫;乳制品山羊;缩合单宁;生产

On both, goats were kept in two groups of 10 animals each. Groups were: control, without treatment (CG) and CT supplemented (CTG) daily with 25 g (1,25%) in E1 and 75 g (2%) in E2. During the E1, feeding was based on Lucerne (Medicago sativa) grazing and supplementation with 500 g of corn grain and during the E2, stabled milking goats ate 500 g of corn grain and ad libitum lucerne hay. Biweekly, faecal egg counts (FEC) and coprocultures were made. In addition, FAMACHA© technique, body condition score (BCSS) and ingested food were recorded each two weeks during the 90 days (E1) and 76 (E2) days of trial. The FEC values in most of the study were low and no significant differences (p<0.78) were detected between groups. Mean FEC were 534 (CTG) and 357 (CG) during E1 and 509 (CTG) and 484 (CG) during E2. The predominant NGI genera were Trichostrongylussp. (48.1%), Haemonchus sp. (39.9%) and Teladorsagia sp. (12.0%). FAMACHA© scores did not show significant (p<0.41) differences between groups, but the CG (median=3) showed a BCS significantly (p<0.05) higher than those of CTG (median=2.5). The average milk production did not present statistically significant differences between groups (p<0.57), between sampling dates (p<0.23) and group x sampling dates (p<0.65).
