Wild animals in Zoos across the globe are kept for aesthetic, educational, recreational and conservation purposes. Collections of rare and endangered species are also preserved in Zoos. Lions do well in captivity but are prone to excessive worm burden especially round worms and tapeworms though these conditions can easily be managed with adequate Veterinary services. Incidence of toxocariasis in captive African lions (Panthera leo) in Nigeria has largely not been reported. Jos Zoo and Wildlife Park both in Plateau State of Nigeria have lost significant number of lions to toxocariasis due to inadequate Veterinary attention A fatal case of toxocariasis in an African Lioness in Jos Zoological Garden, Nigeria was presented as a case study.
世界各地的动物园里的野生动物都是出于审美、教育、娱乐和保护的目的而饲养的。动物园里还保存着一些珍稀和濒危物种。狮子在圈养中表现良好,但容易受到过多的蠕虫负担,特别是圆虫和绦虫,尽管这些情况可以通过适当的兽医服务轻松控制。尼日利亚圈养非洲狮(Panthera leo)弓形虫病的发病率在很大程度上没有报道。由于兽医关注不足,尼日利亚高原州的乔斯动物园和野生动物园因弓形虫病失去了大量狮子。尼日利亚乔斯动物园的一头非洲狮发生致命弓形虫病,这是一个案例研究。

Brucellosis is one of the most important zoonosis in the world; it is highly contagious and caused by a group of organisms in the genus Brucella. The disease remains endemic in Nigeria and its actual incidence and prevalence are unknown due to both inadequate surveillance and systems of reporting outbreaks. This study was designed to determine the sero-prevalence of bovine brucellosis in Ilorin, Kwara State, a gateway to states, and countries engaging in livestock trades within and around Nigeria. A total of 224 blood samples were randomly collected from cattle slaughtered at the two metropolitan abattoirs in the city. The study employed a combination of 2 serological techniques; the Rose Bengal Plate Test (RBPT) and the Serum Agglutination Tube Test (SAT). Of the 224 cattle screened, 10.71% tested positive with Rose Bengal Antigen, while 11.16% tested positive for Serum Agglutination Tube Test (SATT). Prevalence was higher in cows (11.44%) than in bulls (8.69%). There was no significant relationship between the prevalence of bovine brucellosis and any of the variables examined. However, the overall prevalence (11.16%) observedin the study was significant. Thus, the need for drastic public health interventions/control measures on brucellosis in the livestock industry in Nigeria.
布鲁氏菌病是世界上最重要的人畜共患病之一;它具有高度传染性,由布鲁氏菌属的一组生物引起。该病在尼日利亚仍为地方病,由于监测和疫情报告系统不足,其实际发病率和流行率尚不清楚。本研究旨在确定尼日利亚境内及周边从事牲畜贸易的国家的牛布鲁氏菌病血清流行情况。Kwara州是通往各州的门户。随机抽取了该市两个大都会屠宰场屠宰的牛的血液样本共224份。该研究采用了两种血清学技术的组合;玫瑰孟加拉平板试验(RBPT)和血清凝集管试验(SAT)。在筛选的224头牛中,玫瑰孟加拉抗原阳性10.71%,血清凝集管试验(SATT)阳性11.16%。母牛的患病率(11.44%)高于公牛(8.69%)。牛布鲁氏菌病的流行与所检查的任何变量之间没有显著的关系。然而,研究中观察到的总体患病率(11.16%)是显著的。因此,有必要对尼日利亚畜牧业中的布鲁氏菌病采取严厉的公共卫生干预/控制措施。

Multiple drug resistant (MDR) strains of Salmonella are frequently encountered with increased rates in recent years. Many variants of the organism have developed MDR genes which they retain even when antimicrobial drugs are no more in use, limiting the choice of drugs for therapy of Salmonella infections resulting in morbidity and mortality in both man and animals and raising more public health questions. The objective of this study was to evaluate the susceptibility of Salmonella spp. to twelve antimicrobial agents using the disk diffusion method. Eight Salmonella spp. isolated from wildlife were tested. All the isolates exhibited MDR, showing resistance to at least four and up to nine antimicrobial agents. They were all highly resistant (100%) to ceftazidime, cephazoline, cefuroxidine and ampicillin but were susceptible to nalidixic acid and ciprofloxacin. Six resistant patterns were observed, with ampicillin-cefuroxime sodiumcephazolin-ceftazidime and streptomycin-ampicillin-cefuroxime sodium-cephazolin-ceftazidime resistant patterns exhibited by two isolates each. The substantial multiple resistance pointed to the fact that limitations could be faced in choosing drugs for the treatment of Salmonella infections and that mortality and economic losses could be experienced especially if sensitivity tests are not carried out before antimicrobial choice is made for treatments in both man and animals.
近年来,沙门氏菌的多重耐药(MDR)菌株经常出现,并且发病率上升。沙门氏菌的许多变种产生了耐多药基因,即使在不再使用抗微生物药物的情况下,这些基因仍保留着,这限制了治疗沙门氏菌感染的药物选择,导致人类和动物发病和死亡,并引发更多的公共卫生问题。本研究采用纸片扩散法对沙门氏菌对12种抗菌药物的敏感性进行了评价。对从野生动物中分离的8种沙门氏菌进行了检测。所有分离株均表现出耐多药,对至少4至9种抗菌素具有耐药性。对头孢他啶、头孢唑啉、头孢呋啶和氨苄西林均有高度耐药(100%),但对萘啶酸和环丙沙星敏感。观察到6种耐药模式,其中氨苄西林-头孢呋辛钠-头孢他啶和链霉素-氨苄西林-头孢呋辛钠-头孢唑林-头孢他啶各有2种耐药模式。大量的多重耐药性表明,在选择治疗沙门氏菌感染的药物时可能面临限制,特别是如果在选择用于治疗人和动物的抗菌素之前不进行敏感性试验,可能会造成死亡和经济损失。

Fatal Parasitic Gastroenteritis and Pneumonia In A Captive African Civet (Civettictis civetta) 圈养非洲果子狸致死性寄生虫肠胃炎和肺炎(果子狸炎)

The African civet cat (Civetticus civetta) is native to Ethiopia, Guinea, Senegal, and other places in equatorial Africa. Civet cats are grouped under order Carnivora and family Viverridae and are wild viverids of the tropics. They are nocturnal and solitary animals that only mix during mating. Though, civet cats are primarily carnivorous, they are opportunistic omnivores, but feeds on a mixture of fruits and vegetables, maize meal and meat (1kg/civet), eggs, insects, rodents, invertebrates and birds. Parasitic and infectious diseases have become a major concern in the conservation of endangered species as they can cause mortality, dramatic population declines, and even contribute to local extinction events. This report concern is about a Civet which was acquired in May, 2016 by the private forest garden. It showed no previous sign of illness prior to its death in July. The carcass weighed approximately 4kg and was in good bodily condition. Congestion of the lungs were evident, while the stomach was empty, but the duodenum contained cream-coloured mucoid exudates admixed with two long cestodes, measuring up to 52cm and numerous short segments of this worm, (up to 2 cm in length) within the lumen of the proximal 1/3rd of the duodenum and extending to the jejunum and ileum. Parasitological examination revealed that the cestodes was Dipylidium spp. It was concluded that, the Civet could have died as a result of parasitic gastroenteritis and pneumonia 53 days after it was introduced into the forest garden. It is most likely that the infection was acquired from the wild before the animal was introduced into the forest garden.
非洲麝香猫(Civetticus civetta)原产于埃塞俄比亚、几内亚、塞内加尔和赤道非洲的其他地方。果子狸属于食肉目和果子狸科,是热带地区的野生果子狸。它们是夜行性独居动物,只在交配时交配。虽然果子狸主要是肉食性动物,但它们是机会主义杂食动物,但以水果和蔬菜、玉米粉和肉(每只果子狸1公斤)、鸡蛋、昆虫、啮齿动物、无脊椎动物和鸟类为食。寄生虫病和传染病已成为保护濒危物种的一个主要问题,因为它们可能导致死亡、种群急剧下降,甚至导致局部灭绝事件。本报告关注的是一只麝香猫,它于2016年5月被私人森林花园收购。它在7月份死亡之前没有任何疾病迹象。这具尸体重约4公斤,身体状况良好。肺充血明显,胃空,但十二指肠含有奶油色粘液渗出物,混合有两个长蛔虫,长52cm,在十二指肠近1/3的管腔内有许多短段蛔虫(长2cm),并延伸到空肠和回肠。经寄生虫学检查,该果子狸属双子狸科,可能是在进入森林花园53天后,因寄生虫性肠胃炎和肺炎而死亡。最有可能的是,这种感染是在动物被引入森林花园之前从野外获得的。

Free radicals are implicated as a cause and consequence of diverse health pathologies including neuro-degenerative diseases, cardiovascular ailments, diabetes mellitus, cancer, nephropathies, inflammatory disorders, auto-immune diseases, idiosyncratic reactions etc. There is however a renewed interest in the study of plants for novel antioxidants. The present study evaluated the antioxidant properties of the ethanol extract of Date palm (Phoenix datylifera L.) fruit using 2,2 diphenyl-1-picrylhydrazyl (DPPH) assay and also conducted phyto-chemical analysis using standard protocols. The crude extract produced a reduced antioxidant effect compared to ascorbic acid. Specifically, at high test concentrations (0.50 and 0.25 mg/ml), the mean antioxidant activity of the extract was 65.7% and 55.2% respectively relative to 79.0% and 76.8% with ascorbic acid at the same concentration. The extract also induced an abysmally low antioxidant activity of less than 32% below 0.25 mg/ml. Phyto-chemical analysis revealed that the extract contained flavonoids, alkaloids, steroids, terpenoids and cardiac glycosides. Phoenix datylifera L. fruit could be a potential source for isolation of potent antioxidant principles..
自由基是多种健康疾病的起因和结果,包括神经退行性疾病、心血管疾病、糖尿病、癌症、肾病、炎症性疾病、自身免疫疾病、特异性反应等。然而,人们对研究植物的新型抗氧化剂重新产生了兴趣。本研究采用2,2二苯基-1-苦味酰肼(DPPH)法评价了枣椰树果实乙醇提取物的抗氧化性能,并采用标准方案进行了植物化学分析。与抗坏血酸相比,粗提取物的抗氧化作用降低。在高浓度(0.50和0.25 mg/ml)下,提取物的平均抗氧化活性分别为65.7%和55.2%,而在相同浓度下,抗坏血酸提取物的平均抗氧化活性分别为79.0%和76.8%。当浓度低于0.25 mg/ml时,其抗氧化活性低于32%。植物化学分析表明,该提取物含有黄酮类化合物、生物碱、类固醇、萜类化合物和心脏苷类化合物。凤凰果可能是有效抗氧化原理的潜在来源。

The Management of Pain In Animals on The Clinic Floor 临床动物疼痛的管理
Pub Date : 2019-02-01 DOI: 10.36108/jvbs/9102.20.0172
J. Omamegbe, F. Nwinyi
Most animals presented for veterinary care are suffering or will suffer from some pain during restraint, clinical examination, samples collection, diagnostic imaging, parenteral drug administration or clinical procedures et cetera. The Veterinarian is ethically, morally and professionally enjoined to recognize and alleviate such pain. Although most studies on animal pain have been focused on mostly post surgical pain in dogs and cats, animals afflicted with most common external or internal, infectious and non-infectious disease conditions also suffer from pain. Identifying animals in pain alone is difficult except if a Veterinarian with a penchant for the management of pain in animals actively looks out for it in patients. The measurement of pain in animals poses even more difficulties for the Veterinarian than its identification mainly because animals are unable to communicate the locations, the temporal occurance and the severities of the pain they feel just as they don’t of other clinical manifestations. Therefore, animals in pain rely on their owners, handlers or keepers et cetera who actually don’t know how or where it hurts them to provide such details to the Veterinaruan. To complicate matters, the use of validated pain assessment scales in animals is fraught with serious limitations except to some less extent, for the visual analog and the simple descriptive scales which seem applicable in real clinic situations. A multi-modal mode of management in which opioids, non-steroidal anti-inflammatory drugs, local anesthetics, α 2 – adrenergic agonists, NDMA receptor antagonists and ketamine delivered through a variety of routes, at varied dosages and regimens, is advocated for pain management in animals. The need to regularly review the state of the patient vis-à-vis the need to modify the treatment module and regimen cannot be over emphasized when and if a clinical case is under consideration. This may involve the change of medications, the addition of more medications, the reduction in the number of medication, changes in dosages and the regimen in use from time to time. This discuss is aimed at the general Veterinary practitioner who is presented daily with different species and breeds of animals suffering from varieties of clinical conditions or which will undergo a variety of clinical procedures capable of causing pain in the course of veterinary health care delivery in diverse clinic settings.
大多数接受兽医护理的动物在约束、临床检查、样本采集、诊断成像、肠外药物管理或临床程序等过程中都遭受或将遭受一些疼痛。兽医在伦理上、道德上和专业上都被要求承认并减轻这种痛苦。虽然大多数关于动物疼痛的研究主要集中在狗和猫的手术后疼痛,但患有最常见的外部或内部,感染性和非感染性疾病的动物也会遭受疼痛。单独识别动物疼痛是很困难的,除非有一个对动物疼痛管理有兴趣的兽医积极地寻找病人。对兽医来说,测量动物的疼痛比识别疼痛更困难,主要是因为动物无法交流疼痛的位置、发生的时间和严重程度,就像它们无法交流其他临床表现一样。因此,疼痛的动物依赖于它们的主人,训导员或饲养员等等,他们实际上不知道它们是如何或在哪里受伤的,向兽医提供这些细节。更复杂的是,在动物身上使用经过验证的疼痛评估量表,除了在某种程度上存在严重的局限性,因为视觉模拟和简单的描述性量表似乎适用于真实的临床情况。阿片类药物、非甾体抗炎药、局部麻醉剂、α 2 -肾上腺素能激动剂、NDMA受体拮抗剂和氯胺酮通过多种途径、以不同剂量和方案递送的多模式管理模式,被提倡用于动物疼痛管理。在考虑临床病例时,需要定期审查患者的状态(参见-à-vis),需要修改治疗模块和方案,这一点再怎么强调也不为过。这可能涉及药物的变化,增加更多的药物,减少药物的数量,改变剂量和使用的方案不时。本讨论针对的是普通兽医从业人员,他们每天都要面对不同种类和品种的动物,这些动物患有各种各样的临床疾病,或者在不同的临床环境中,在兽医卫生保健提供过程中,将经历各种各样的临床程序,这些程序可能会引起疼痛。

A 5-year-old Sokoto Gudali bull was presented with complaint of recurrent soft and flocculent swelling beneath the tongue. Careful clinical assessment led to a diagnosis of sublingual sialocele. A sialocele is a subcutaneous cavity containing saliva which is surrounded by tissue reaction to saliva. An aspirate of the fluid revealed a clear viscid content with neutrophils, lymphocytes and monocytes. The case was managed surgically by marsupialization. Recovery was “uneventful” and was found to be normal 2 months post-surgery. It was concluded that marsupialization technique may be a permanent remedy for recurring sublingual sialocele in cattle.

This study was carried out to determine the gastrointestinal parasites in local and exotic breed of turkeys reared in Gwagwalada, Guinea savannah Zone of Nigeria. It was conducted between May and September, 2017. One hundred [100] faecal samples were collected from local and exotic breeds of turkeys in Gwagwalada Area Council and examined for the presence of gastrointestinal parasites eggs and oocysts using flotation and sedimentation methods. The following parasites eggs/oocysts were identified in the study; Ascaridia spp [47%], Strongyloides spp [32%], Cappilaria spp [26%], Heterakis spp [25%], Tetrameres spp [24%], Spirurid spp [15%], Raillientina spp[13%], Davainea spp [10%], Subulura spp [6%], Oxyuris spp [6%], Cyathostoma spp [5%], Syngamus spp [5%]. The Oocysts identified belonged to Eimeria spp [41%], Cryptosporidium spp [34%], Sarcocystis spp [6%], Trichomonas spp [4%]. A total of 95% of the turkeys were infected, with majority of the birds having mixed infection. Interestingly, none of the turkeys examined was infected with trematodes. There was no statistically significant difference in prevalence [p>0.05] among the Turkeys. There was difference [p<0.05] in the prevalence of infected male and female turkeys. The females had higher Infestation with the parasites than the males. There was no significant difference [p>0.05] among the age groups. The prevalence of gastrointestinal parasites in this study shows a higher occurrence in exotic breed of turkeys 58.9% when compared to the local breed 41.1%. The domestic turkeys raised are hosts of a great number of gastrointestinal parasites which is attributed to the production system to which they belong. Therefore, Turkeys raised in free range condition of breeding should have a boundary and food served to them to reduce their search for food which exposes them to intermediate hosts of parasites.
本研究对尼日利亚几内亚大草原地区瓜瓦拉达饲养的本地和外来火鸡的胃肠道寄生虫进行了研究。调查于2017年5月至9月进行。从Gwagwalada地区委员会的本地和外来火鸡品种收集了100[100]份粪便样本,并使用浮选和沉淀法检查了胃肠道寄生虫卵和卵囊的存在。在研究中发现了以下寄生虫卵/卵囊:蛔虫属[47%]、圆线虫属[32%]、毛线虫属[26%]、异线虫属[25%]、四分体属[24%]、螺旋体属[15%]、铁线虫属[13%]、Davainea属[10%]、亚种属[6%]、Oxyuris属[6%]、Cyathostoma属[5%]、Syngamus属[5%]。所鉴定卵囊属艾美耳球虫属(41%)、隐孢子虫属(34%)、肉囊虫属(6%)、毛滴虫属(4%)。共有95%的火鸡被感染,其中大多数是混合性感染。有趣的是,被检查的火鸡中没有一只感染了吸虫。火鸡的患病率差异无统计学意义[p>0.05]。各年龄组间差异有统计学意义[p0.05]。在本研究中,胃肠道寄生虫的患病率在外来品种火鸡中为58.9%,高于本地品种的41.1%。饲养的家养火鸡是大量胃肠道寄生虫的宿主,这归因于它们所属的生产系统。因此,在自由放养条件下饲养的火鸡应该有一个边界,并为它们提供食物,以减少它们寻找食物,从而使它们暴露于寄生虫的中间宿主。

Turmeric (curcuma longa) is a rhizomatous herbaceous perennial plant of the ginger family and the order Zingerberales. It is widely cultivated and used in the treatment of various ailments. In this study, the effect of aqueous extract of C. longa on isolated rabbit jejunum was investigated in vitro using Physiograph (Meditech, India). The rhizome of Curcumin was extracted using Soxhlet extraction method and distilled water was used as a solvent. The elemental analysis was determined using AAS and the result revealed the presence of Potassium, Magnesium, Iron and Nitrogen. The percentage concentrations of trace elements in the aqueous Curcumin rhizome were within the WHO standard limit. The aqueous extract at concentration tested (100 mg/ml) significantly decreased (p<0.05) jejunum smooth muscle contraction. Addition of Atropine (1mM) or Propranolol (1mM) further decreased the amplitude of jejunum smooth muscle contraction. Curcumin rhizome (100 mg/ml) blocked contraction induced by Ach (0.001μg/ml). The result of this work has shown that rhizome of C. longa produced jejunum smooth muscle relaxation, plant extract with antispasmodic activity may reduce gastrointestinal motility thereby delay gastric emptying and may be important in treatment of disease ailments like diarrhoea and colic.
姜黄(curcuma longa)是姜科多年生根茎草本植物。它被广泛种植并用于治疗各种疾病。在本研究中,利用Physiograph (Meditech, India)研究了长藤水提物对离体家兔空肠的影响。采用索氏提取法,以蒸馏水为溶剂提取姜黄素。原子吸收光谱法测定了样品的元素,发现样品中存在钾、镁、铁和氮。姜黄素水溶液中微量元素含量均在WHO标准范围内。试验浓度(100 mg/ml)显著降低空肠平滑肌收缩(p<0.05)。添加阿托品(1mM)或心得安(1mM)可进一步降低空肠平滑肌收缩幅度。姜黄素(100 mg/ml)阻断乙酰胆碱(0.001μg/ml)诱导的收缩。本研究结果表明,长藤根茎可使空肠平滑肌松弛,具有抗痉挛活性的植物提取物可减少胃肠运动,从而延缓胃排空,可能对治疗腹泻和绞痛等疾病有重要作用。

Growth and survival of Clarias gariepinus in different water qualities were investigated. Initially, water of equal quality was used for the experiment, later the quality of water varies due to period of water change, (daily-T4, weekly-T3, bi-weekly-T2 and monthly-T1). Physico-chemical parameters were analyzed. Two hundred and forty (240) seven weeks old fingerlings of C. gariepinus were randomly distributed into 12 plastic tanks. Poor growth of C. gariepinus was observed in the treatment tanks (T1, T2 and T3), compared with growth of fish in the control (T4) which was progressive as indicated by the higher value of condition factor. Treatment tanks had significantly (P < 0.05) higher EC, TDS, Turbidity, Ammonia, Nitrate and Nitrite and significantly (P < 0.05) lower DO than culture water in control container. Slight growth was recorded for fish in T1 and T2 until the second week when drop in fish weight was observed. This study has shown that poor water quality can reduce growth rate and survival of C. gariepinus.
研究了不同水质条件下加里平Clarias gariepinus的生长和存活情况。实验初期采用等质水,后期根据换水周期(每日- t4、每周- t3、双周- t2、每月- t1),水质发生变化。分析了理化参数。将240尾7周龄的加里滨棘鱼鱼种随机分配到12个塑料池中。试验池(T1、T2和T3)中加里滨沙鱼生长较差,而对照组(T4)中生长呈进行性,条件因子值较高。处理池的EC、TDS、浊度、氨氮、硝酸盐和亚硝酸盐显著(P < 0.05)高于对照组,DO显著(P < 0.05)低于对照组。在第1周和第2周,鱼体略有生长,直到第2周,鱼体体重下降。本研究表明,水质差会降低加里滨棘鱼的生长速度和成活率。
