Aim: The aim of this study is to determine the efficacy of extracts of some selected plant materials in the control of Powdery Mildew of Okra plant. Study Design: Completely randomized design. Place of Study: This study was carried out in the Biology Laboratory of the Department of Plant Science and Biotechnology. Methodology: Three Okra farms showing symptoms of powdery mildew disease were surveyed, disease occurrence was recorded, and disease incidence was calculated. Leaves of okra (Abelmoschus esculentus) showing symptoms of powdery mildew were collected from the farms. The disease incidence was recorded and the samples of infected leaves were collected from the farms and taken to the laboratory for microscopic examination. The fungus associated with the disease was isolated and cultured to obtain a pure culture. Pathogenicity test was carried out on a healthy okra plant. Extraction of the two plants were done using methanol and it was then diluted to different concentrations. The antifungal susceptibility test on Golovinomyces cichoracearum was carried out using the agar diffusion method and recorded at various concentrations of 50 mg/ml, 25 mg/ml, 12.5 mg/ml, and 6.25 mg/ml under in-vitro conditions. The minimum inhibitory concentrations and antifungal activity were recorded at these concentrations. Results: Results of phytochemical analysis showed that Alkaloids, reducing sugars, carbohydrates, Flavanoids, Tannins and Resins were present in both Allium sativum (garlic) and Azadirachta indica (neem). These phytochemicals present are suspected to be responsible for the antifungal activity of the plants. Out of the two plants, neem leaf extract was found to be best in the inhibition of the fungus at 50 mg/ml with a significantly high inhibition of 26.77±0.50 after the treatment. At P<= 0.05 there was a significant difference in the antifungal activity of the extract of A. indica on Golovinomyces cichoracearum. Conclusion: The extracts of both Allium sativum (garlic) and Azadirachta indic (neem) possess antifungal properties, and may have the potential for the production of biopesticides, that can be used for the control of fungi.
目的:研究几种植物提取物对秋葵白粉病的防治效果。研究设计:完全随机设计。研究地点:本研究在植物科学与生物技术系生物实验室进行。方法:对3个有白粉病症状的秋葵养殖场进行调查,记录病害发生情况,计算病害发病率。从农场收集了有白粉病症状的秋葵叶。记录发病情况,并从农场采集感染叶片样本,带到实验室进行显微镜检查。分离培养与该病相关的真菌,获得纯培养物。在健康秋葵植株上进行了致病性试验。用甲醇提取两种植物,然后稀释到不同的浓度。采用琼脂扩散法对环心戈洛维菌进行了体外药敏试验,记录了50 mg/ml、25 mg/ml、12.5 mg/ml、6.25 mg/ml等不同浓度条件下对环心戈洛维菌的抑菌敏感性。在这些浓度下记录了最低抑菌浓度和抗真菌活性。结果:植物化学分析结果表明,大蒜和印楝中均含有生物碱、还原糖、碳水化合物、类黄酮、单宁和树脂。这些植物化学物质被怀疑是植物抗真菌活性的原因。在两种植物中,印楝叶提取物在50 mg/ml时对真菌的抑制效果最好,处理后的抑制率为26.77±0.50。在P<= 0.05的条件下,籼稻提取物对青黄菌的抑菌活性差异有统计学意义。结论:大蒜(Allium sativum)和印楝(Azadirachta indicc)提取物均具有抗真菌活性,具有生产生物农药的潜力,可用于真菌防治。

Plants are a source of first-line treatment for most humans, particularly in Africa and offer nutrition for most terrestrial ecosystems. The world's attention have been called repeatedly to the therapeutic marvels of plants, one of which is Garcinia kola. This study aims to determine the antisalmonella efficacy of several Garcinia kola leaf and seed extracts. Extracts of leaves, seeds, and seed/leaf were obtained using methanol and ethanol as extraction solvents. Inoculated Salmonella typhi were observed for 24 hours using the well diffusion method to determine zones of inhibition. All extracts were found to be effective against S. typhi. 100/50 mg/ml methanol leave extract produced a 14/12mm zone of inhibition, whereas 100/50 mg/ml methanol seed extract produced a 13/11mm zone of inhibition. 100/50 mg/ml ethanol leave extract showed a 17/10mm inhibition zone, while 100/50 mg/ml ethanol seed extract showed a 16/14mm inhibition zone. The inhibition zone of methanol seed/leaf extract of 100/50 mg/ml was 17/12mm, while the inhibition zone of ethanol seed/leaf extract was 19/14mm. While all concentrations of plant extracts were effective against S. typhi, greater concentrations created larger zones of inhibition and the plant extracts outperformed the control. Seed/leaf extracts outperformed seed extract and leaf extract in most cases. The results showed that ethanol was a better extraction liquid and that the leaf extracts were more potent; however, this is not true in all cases. To stimulate local mitigation of illnesses caused by Salmonella typhi, more research on the antisalmonella effectiveness of Garcinia kola seed and leaf extracts should be done.
植物是大多数人的一线治疗来源,特别是在非洲,并为大多数陆地生态系统提供营养。世界的注意力已经被反复呼吁到植物的治疗奇迹,其中一个是藤黄。本研究旨在测定几种藤黄叶和种子提取物的抗沙门氏菌效果。以甲醇和乙醇为提取溶剂,分别获得叶片、种子和种子/叶片的提取物。接种伤寒沙门菌后,用孔扩散法观察24小时,确定抑制区。所有提取物均对伤寒沙门氏菌有效。100/50 mg/ml甲醇叶提取物产生了14/12mm的抑制区,而100/50 mg/ml甲醇种子提取物产生了13/11mm的抑制区。100/50 mg/ml乙醇叶提取物的抑制带为17/10mm, 100/50 mg/ml乙醇种子提取物的抑制带为16/14mm。100/50 mg/ml甲醇种子/叶提取物的抑制带为17/12mm,乙醇种子/叶提取物的抑制带为19/14mm。虽然所有浓度的植物提取物对伤寒沙门氏菌都有效,但浓度越大,抑制区域越大,植物提取物的抑制效果优于对照。在大多数情况下,种子/叶提取物优于种子提取物和叶提取物。结果表明,乙醇是较好的提取液,叶提取物的提取效果较好;然而,并非在所有情况下都是如此。为了促进局部减轻伤寒沙门氏菌引起的疾病,应该对藤黄种子和叶子提取物的抗沙门氏菌效果进行更多的研究。

Introduction: Environmental health encompasses the assessment and control of the environmental factors that can potentially affect health and is targeted towards preventing diseases and creating health-supportive environment. Although, the environmental health indicators are made up of intermediate and impact indicators; these indicators are most routinely used for monitoring the three most common environmental health problems faced in developing countries, which includes Malaria, ARI (Acute Respiratory Infection) and Diarrhoea. This study shows the interrelationship between environmental health condition and WASH diseases (Cholera, Typhoid fever, and Diarrheal). Materials and Methods: A pre-test on analysis of Environmental Health condition in Obio-Akpo LGA, multi-stage sampling procedure was used in selecting a total of 50 respondent who were women, questionnaires were used to elicit data from the respondents and the data was analysed using descriptive statistics, prevalence and correlation. Results: The women in the study area indicated their willingness to participate in the survey when compared to the men, with the women having 50(100%) and the men 0(0%) participation. It was common among the respondents that 37(74%) wash their hands with soap and water while others 13(26%) wash their hands at times with soap and water, and at times they just rinse their hands with water. The diseases related to WASH that occurred in the past 12months among the respondents were 6(12%) had Cholera, Diarrhoea occurred in 10(20%) of the respondents, Typhoid malaria occurred in 13(26%) of the respondents, also Skin Infection and COVID-19 were 1(2%) each. While 19(38%) of the respondents had none of the diseases related to WASH in the past 12 months. The type of toilet facilities had a negative relationship to the prevalence of diseases with a 0.01 level of significance. Discussion: There was prevalence of WASH disease among the respondents and it was above average, it is recommended that the government and non-governmental organisations should provide water in homes and public spaces due to the strong correlation between hand washing and prevalence of diseases.
导言:环境卫生包括对可能影响健康的环境因素的评估和控制,目标是预防疾病和创造有利于健康的环境。虽然环境卫生指标由中间指标和影响指标组成;这些指标最常用于监测发展中国家面临的三种最常见的环境卫生问题,其中包括疟疾、急性呼吸道感染和腹泻。本研究显示环境卫生状况与WASH疾病(霍乱、伤寒和腹泻)之间的相互关系。材料与方法:采用奥比奥-阿克波地区环境健康状况分析的前测方法,采用多阶段抽样法抽取50名女性受访者,采用问卷调查法抽取受访者数据,采用描述性统计、流行率和相关性分析数据。结果:与男性相比,研究区域的女性表示愿意参与调查,女性参与率为50%(100%),男性参与率为0%(0%)。在受访者中,有37人(74%)用肥皂和水洗手,而其他13人(26%)有时用肥皂和水洗手,有时他们只是用水冲洗手。受访者在过去12个月内发生的与WASH有关的疾病为霍乱6例(12%),腹泻10例(20%),伤寒疟疾13例(26%),皮肤感染和COVID-19各1例(2%)。而19名(38%)受访者在过去12个月内没有患任何与WASH有关的疾病。厕所设施类型与疾病患病率呈负相关,显著性水平为0.01。讨论:受访者中存在WASH疾病的患病率,并且高于平均水平,建议政府和非政府组织在家庭和公共场所提供水,因为洗手与疾病患病率之间存在很强的相关性。

Many malaria endemic nations are pursuing malaria elimination and these technical challenges require the development of integrated approaches, among which safe and effective malaria vaccines could be a crucial tool.  Due to non-availability of malaria vaccine, the control efforts rely heavily on treatment with new antimalarial agents preferably acting on newer targets.  In this study, the protected serum proteomics after garlic and arteether combination treatment of P.berghei infected mice has been analyzed by western blotting. One of the identified host parasites specific proteins, peptidyl-prolyl-cis-trans isomerase A (PPIA) is known to catalyze the interconversion of the cis and trans and mediate certain protein folding events both in in vitro and in vivo conditions. This study hypothesizes that, overexpressed PPIA might lead to misfold of the parasite protein which are needed for parasite multiplication and in turn lead to the parasite death or in the protection of combination drug treated samples.
许多疟疾流行国家正在努力消除疟疾,这些技术挑战要求制定综合办法,其中安全有效的疟疾疫苗可能是一个关键工具。由于没有疟疾疫苗,控制工作在很大程度上依赖于使用新的抗疟药进行治疗,最好是针对较新的目标。本研究采用western blotting方法分析了大蒜和蒿醚联合治疗伯氏螺旋体感染小鼠后血清保护蛋白组学的变化。作为宿主寄生虫的特异性蛋白之一,肽酰脯氨酸顺式反式异构酶A (PPIA)在体外和体内均可催化顺式和反式的相互转化,并介导某些蛋白质折叠事件。本研究推测,过表达的PPIA可能导致寄生虫繁殖所需的寄生虫蛋白错误折叠,从而导致寄生虫死亡或对联合药物处理的样品有保护作用。

Aim: To determine the prevalent rates of Escherichia coli O157: H7 and non-O157 strains in of isolates from meat, human stool and abattoir waste water, collected from selected sources in Port Harcourt, Nigeria. Study Design: Case-controlled study. Place and Duration of Study: Selected places in Port Harcourt, Rivers State, Nigeria, between November, 2020 to November, 2021. Methodology: Three hundred and forty -nine (349) samples were analyzed, 80 meat and 63 waste waters from five abattoirs cited in the city, 46 meat samples from five selected sites sold by roadside butchers, 109 patient stool samples and 30 stool samples from food sellers, in addition to 20 stool samples from healthy subjects and 1 commercial bottled water which served as control samples. Tryptone soya broth (TSB) as an enrichment media, selective agar media namely; Eosin methylene blue agar, cefixime tellurite-sorbitol MacConkey agar (CT-SMAC), Chromagar STEC were used to isolate STEC from the samples and serology done with O157 latex agglutinating kit to confirm E. coli O157:H7 serogroup. Results: The results showed that Isolation rates obtained for E. coli O157:H7 and non O157 respectively were: abattoir meat 11(13.8%);13(16.3%), roadside meat 5(10.9%); 10(21.7%), clinical stool 7(6.4%); 27(24.7%), food sellers’ stool 4(13.3%);6(20%), waste abattoir water 2(3%); 14(22.2%). Food sellers and abattoir effluents were found to be potential sources of STEC dissemination in Port Harcourt. The data obtained were statistically analyzed using chi- square which showed that there was no significant difference (p < 0.05) in the rate of isolation of E. coli O157: H7 and non- O157 strain from the samples. Conclusion: The detection of E.coli O157:H7 and non-O157 strains in raw meat (food), environment and clinical samples in Port Harcourt may give rise to a potential widespread public health hazard if strict adherence to proper hygiene management are not place to regulate food processing in other to reduce contamination and foodborne infections.
目的:确定从尼日利亚哈科特港选定来源收集的肉类、人类粪便和屠宰场废水中分离出的大肠杆菌O157: H7和非O157菌株的流行率。研究设计:病例对照研究。学习地点和时间:2020年11月至2021年11月,在尼日利亚河流州哈科特港选择学习地点。方法:对349份样本进行了分析,其中包括来自该市5个屠宰场的80份肉类和63份废水,来自5个选定地点的路边屠夫出售的46份肉类样本,109份患者粪便样本和30份食品销售商的粪便样本,以及来自健康受试者的20份粪便样本和1份商业瓶装水作为对照样本。以色氨酸豆汤(TSB)为富集培养基,即选择性琼脂培养基;采用伊红亚甲基蓝琼脂、头孢克肟-山梨醇麦康基琼脂(CT-SMAC)、Chromagar产志贺大肠杆菌(STEC)分离样品,并用O157胶乳凝集试剂盒进行血清学检测,确定O157:H7血清组大肠杆菌。结果:大肠杆菌O157:H7和非O157分离率分别为:屠宰场肉11例(13.8%)、路边肉13例(16.3%)、路边肉5例(10.9%);10例(21.7%),临床大便7例(6.4%);食品商贩粪便27例(24.7%),4例(13.3%),6例(20%),屠宰场废水2例(3%);14(22.2%)。在哈考特港,食物小贩和屠宰场的污水是产志贺毒素大肠杆菌的潜在传播来源。采用卡方法对所得数据进行统计学分析,结果表明,样品中大肠杆菌O157: H7与非O157菌株的分离率差异无统计学意义(p < 0.05)。结论:在哈科特港的生肉(食品)、环境和临床样本中检测到的大肠杆菌O157:H7和非O157菌株,如果不严格遵守适当的卫生管理,以规范其他食品加工以减少污染和食源性感染,可能会产生潜在的广泛的公共卫生危害。

Background: Bacterial resistance is a more serious threat, and herbal medicines have been used as an alternative solution to this problem. Honey has been used to treat bacterial infections for decades. Methods: This is a prospective cross-sectional study conducted at the Microbiology Laboratory, Faculty of Laboratory Medicine, Shendi, Sudan between October 2021 and November 2021. In this study, 50 different clinical samples were collected from different microbiology laboratories in Shendi City, and different Gram-positive cocci bacteria were isolated and identified by Gram’s staining and biochemical tests. The susceptibility of Gram-positive bacteria to the bee honey was determined using agar well diffusion technique. Results: Out of a total of 50 clinical specimens cultured the most frequent isolated bacteria were Staphylococcus aureus (46%), Streptococcus epidermidis (36%), Streptococcus viridian's (10%), Staphylococcus saprophyticus (4%), while the least isolated bacteria was Enterococcus fecalis (4%). On the other hand, 100% (v/v) honey was more effective than the tested antibiotics, inhibiting 74% of clinical isolates, while 38% of microorganisms were inhibited by only 50% (v/v) honey and 14% of organisms inhibited by 25% (v/v) Honey. Bee honey showed a clear effect on the isolated bacteria. Conclusion: Based on these results, we can conclude that honey has broad activity against Gram-positive bacteria. Therefore, honey can be considered as a broad-spectrum antibacterial agent. The medicinal use of Sudanese honey and the assumption that the possibility of local production of bioactive honey requires additional investigation.
背景:细菌耐药性是一个更严重的威胁,草药已被用作解决这一问题的替代方案。几十年来,蜂蜜一直被用来治疗细菌感染。方法:这是一项前瞻性横断面研究,于2021年10月至2021年11月在苏丹申迪检验医学学院微生物实验室进行。本研究从沈迪市不同微生物实验室采集50份不同的临床标本,通过革兰氏染色和生化试验分离鉴定不同的革兰氏阳性球菌。采用琼脂孔扩散法测定革兰氏阳性菌对蜂蜜的敏感性。结果:在50份临床标本中,分离最多的细菌为金黄色葡萄球菌(46%)、表皮链球菌(36%)、绿质链球菌(10%)、腐生葡萄球菌(4%),分离最少的细菌为粪肠球菌(4%)。另一方面,100% (v/v)蜂蜜比测试的抗生素更有效,抑制74%的临床分离株,而38%的微生物仅被50% (v/v)蜂蜜抑制,14%的微生物被25% (v/v)蜂蜜抑制。蜜蜂蜂蜜对分离出来的细菌有明显的效果。结论:蜂蜜具有广泛的抗革兰氏阳性菌活性。因此,蜂蜜可以被认为是一种广谱抗菌剂。苏丹蜂蜜的药用用途和当地生产生物活性蜂蜜的可能性的假设需要进一步调查。

Background: Cryptosporidium is an etiologic agent of gastro-intestinal disorders and severe, profuse watery diarrhoea in immunocompromised patients, such as people living with HIV/AIDS. Aim: This study was carried out to determine the genotypic and phylogenetic characteristics of Cryptosporidium parvum among HIV patients who usually received antiretroviral therapy (ART) in four selected hospitals in Maiduguri Metropolis. Study Design: This is a clinical laboratory study of opportunistic pathogens in HIV/AIDS Patients. Place and Duration of Study: This was conducted at the Department of Medical Laboratory Science, the University of Maiduguri in collaboration with the Biological Sciences Department, ATBU Bauchi, Nigeria, between March 2021, and February 2022. Methods: A total of 400 faecal specimens were collected from confirmed HIV-positive patients and screened for Cryptosporidium-specific antigen by Enzyme Link Immunosorbent Assay (ELISA). Genomic DNA Extraction was done by Quick-DNATM Faecal Microbe Miniprep with PCR amplification and sequencing of 18s SSU rRNA gene using specific reference primers. Results: Out of the 70 HIV/AIDS and Cryptosporidium co-infected patients, 20 of the samples contained 18s SSU rRNA genes, with the highest frequency (45.0%) found in patients from the University Teaching Hospital. The results of phylogenetic analyses indicated that there is significant intra-species diversity in the genus Cryptosporidium. The four human C. parvum isolates differ from the bovine and the two avian isolates in three regions of the 18s rRNA gene. Conclusion: The human genotype (genotype I) found in this study is exclusively human and in a single non-human primate, in bovine genotype (genotype II) has proved to be anthroponotic and zoonotic to the livestock. The study, therefore, advocates further genotyping of Cryptosporidium from both HIV-infected patients and immunocompetent hosts from various regions together with surveillance of animal and environmental reservoirs is highly recommended.
背景:隐孢子虫是免疫功能低下患者(如艾滋病毒/艾滋病感染者)胃肠道疾病和严重、大量水样腹泻的病原。目的:研究在迈杜古里市选定的四家医院接受抗逆转录病毒治疗(ART)的HIV患者中细小隐孢子虫的基因型和系统发育特征。研究设计:这是一项HIV/AIDS患者机会致病菌的临床实验室研究。研究地点和时间:研究于2021年3月至2022年2月在迈杜古里大学医学实验室科学系与尼日利亚包奇大学生物科学系合作进行。方法:收集400例hiv确诊阳性患者粪便标本,采用酶联免疫吸附试验(ELISA)筛选隐孢子虫特异性抗原。基因组DNA提取采用Quick-DNATM粪便微生物Miniprep, PCR扩增,特异参考引物测序18s SSU rRNA基因。结果:在70例HIV/AIDS和隐孢子虫合并感染的患者中,有20例样本含有18s个SSU rRNA基因,其中以大学教学医院患者的频率最高(45.0%)。系统发育分析结果表明,隐孢子虫属具有明显的种内多样性。4个人分离的小孢子虫在18s rRNA基因的3个区域与牛分离的小孢子虫和2个禽分离的小孢子虫不同。结论:在本研究中发现的人类基因型(基因型I)完全是人类和单一的非人类灵长类动物,在牛基因型(基因型II)已被证明是人畜共患。因此,该研究提倡对来自不同地区的hiv感染患者和免疫能力强的宿主进行进一步的隐孢子虫基因分型,并强烈建议对动物和环境宿主进行监测。

Aim: This study is aimed at Isolating and Identifying the Toxigenic Aspergillus species Associated With Sorghum Grains and Locally Brewed Beer (Burkutu) in Bukuru Metropolis of Jos South Local Government Area, Nigeria. Methodology: Sorghum grains and locally brewed beer (Burkutu) were collected from three different locations; Gyel, Kugiya, and Doruwa Market of Bukuru Metropolis of Jos South Local Government Area, and Screened for their fungal and total aflatoxin level. The grains were blended for 30 seconds using a high-speed blender. 1 gram of the blended sorghum and 1ml of the Burkutu sample (local beer) were cultured into freshly prepared PDA supplemented with 0.5mg/ml of gentamycin and streptomycin to suppress bacterial growth. This was then incubated at a temperature of 37°C for 72 hours after which various fungi colonies were observed and counted with a colony counter. The fungi isolated were further sub-cultured to obtain pure cultures after which they were classified using conidial morphology as obtained from microscopy. Lactophenol cotton blue mount was also carried out to identify the exact fungi with reference to a mycological atlas. The colony-forming unit for each sample was determined, and the Aflatoxin test was carried out using a Mycotoxin kit (the Rida Quick Scan method) to determine the Total aflatoxin level. Results: The Aspergillus species found in both Sorghum grains and Burkuru (local beer) were: Aspergillus niger, Aspergillus flavus, and Aspergillus fumigatus. For sorghum grains, Aspergillus niger had the highest frequency of occurrence (42.86%) while Aspergillus flavus & Aspergillus fumigatus occurred equally with (28.57%) respectively. Aspergillus flavus had the highest frequency of occurrence in Burkutu (50%), followed by Aspergillus niger (33.33%) and the least was Aspergillus fumigatus (16.67%). The highest aflatoxin level for grains was detected in Kugiya which had (3.6 parts per billion) followed by the grain sample from Gyel which had (3.0 Ppb) and the least was Doruwa (2.8 Ppb). Burkutu had the highest total level of aflatoxin (3.1Ppb) in the sample from Gyel, followed by Burkutu from Doruwa (2.6 Ppb) and the least was from Kugiya (2.4 Ppb). Conclusion: Both the sorghum grains and Locally Brewed Beer (Burkutu) collected from the Bukuru Metropolis of Jos South Local Government Area, Nigeria were significantly contaminated by the toxigenic Aspergillus species. This indicates possible health hazards for humans and animals ingesting these substances. However, effective screening of these grains for aflatoxins is advocated to ensure the safety of both grains and their products.
目的:分离和鉴定尼日利亚乔斯南部地方政府区Bukuru大都市高粱谷物和当地酿造啤酒(Burkutu)相关的产毒曲霉。方法:从三个不同的地点收集高粱谷物和当地酿造的啤酒(Burkutu);Jos South地方政府区Bukuru Metropolis的Gyel, Kugiya和Doruwa市场,并筛选其真菌和总黄曲霉毒素水平。谷物用高速搅拌器搅拌30秒。将混合后的高粱1克和Burkutu样品(当地啤酒)1ml培养成新鲜配制的PDA,并添加0.5mg/ml庆大霉素和链霉素抑制细菌生长。然后在37°C的温度下孵育72小时,之后用菌落计数器观察和计数各种真菌菌落。分离的真菌进一步继代培养以获得纯培养物,然后使用显微镜下获得的分生孢子形态对其进行分类。乳酚棉蓝mount也进行了确定确切的真菌参考真菌学图谱。确定每个样品的菌落形成单位,并使用霉菌毒素试剂盒(Rida快速扫描法)进行黄曲霉毒素检测,以确定总黄曲霉毒素水平。结果:在高粱谷物和Burkuru啤酒中发现的曲霉种类有:黑曲霉、黄曲霉和烟曲霉。高粱籽粒中,黑曲霉的发生频率最高(42.86%),黄曲霉和烟曲霉的发生频率相同(28.57%)。Burkutu地区黄曲霉的出现频率最高(50%),黑曲霉次之(33.33%),烟曲霉最少(16.67%)。谷谷县的谷物中黄曲霉毒素含量最高,为3.6 Ppb,其次是吉尔县,为3.0 Ppb,多鲁瓦县最低,为2.8 Ppb。来自Gyel的样品中Burkutu的黄曲霉毒素总含量最高(3.1Ppb),其次是来自Doruwa的Burkutu (2.6 Ppb),来自Kugiya的Burkutu最低(2.4 Ppb)。结论:在尼日利亚乔斯南部地方政府区Bukuru大都市采集的高粱籽粒和当地酿造的啤酒(Burkutu)均受到产毒曲霉的严重污染。这表明摄入这些物质可能对人类和动物的健康造成危害。然而,人们提倡对这些谷物进行有效的黄曲霉毒素筛选,以确保谷物及其产品的安全。

Different parts of the plant such as leaves, roots, latex, seeds, fruits and other parts have been reported to have different compounds which have interesting bioactivities and antiviral properties. \u0000Conclusion: The present mini-review can therefore help inform future scientific research towards the development of anti-Hepatitis B virus and antiCovid-19 herbal drugs of relevance as well as nutraceuticals from J. curcas for the improvement of human health and wellbeing using reverse pharmacology approach. Molecular docking of some naturally occurring isolate compounds against anti-Hepatitis B virus protease is in progress.","PeriodicalId":129993,"journal":{"name":"International Journal of Pathogen Research","volume":"517 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123693416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
