Mpox disease is caused by a double-stranded DNA virus, genus Orthopoxvirus of the family Poxviridae. The incubation period is usually 6 to 13 days but can range from 5 to 21 days while symptoms and signs may persist for 2 to 5 weeks. Although, the clinical features are usually less severe when compared to the deadly smallpox, the disease can be fatal with case fatality rate between 1% and 10%. In Imo State, Nigeria, there has been a changing epidemiology of the disease in the last 6 years and the frequency and geographic distribution of cases have progressively increased. This study aims to conduct a review of the disease epidemiology between 2017 and 2023 and implications for surveillance in Imo State. Surveillance data from the Surveillance Outbreak Response and Management System (SORMAS) was extracted between January 2017 and December 2023 across the 27 Local Government Areas (LGAs) of Imo State. A line list of 231 suspected cases was downloaded into an excel template and analyzed using SPSS® version 20 software. Analysis was done using descriptive statistics and associations were tested using Fischer’s exact at 0.05 level of significance. Of the 231 suspected cases, 57.1% (132) were males, 42.9% (99) were females and the modal age group was between the ages of 0 - 4 (32.5%). Eight (8) LGAs (districts) accounted for 71% (n = 164) of all the suspected cases. 21.2% (49) were confirmed positive, 27 males (55.1%) and 22 females (44.9%) (p > 0.05). Modal age group was 20 - 24 (22.4%, n = 11), 18% (9) were children under 14 years, p > 0.05. Case fatality rate was 8% (n = 4). There was no significant association between mortality and age group. Five (5) LGAs accounted for about 60% (29) of all confirmed cases. These LGAs contribute only 20% to the total population in the State. Only 5.6% and 4% of suspected and confirmed cases, respectively, had knowledge of contact with an infectious source. The study described the epidemiology of Mpox outbreaks between 2017

文章研究了罗布麻茎叶粗提物对大肠杆菌、金黄色葡萄球菌和黄曲霉的抑菌活性和最小抑菌浓度,并定性分析了脱胶后的罗布麻纤维对上述类型微生物的抑制效果。结果表明,罗布麻茎叶粗提物对黄曲霉和金黄色葡萄球菌的抑制效果较为明显,对大肠杆菌抑制效果稍差,其中,罗布白麻和罗布红麻对黄曲霉菌的最小抑菌浓度分别为5、7.5 mg/mL,对金黄色葡萄球菌最小抑菌浓度均为7.5 mg/mL,而对大肠杆菌的最小抑菌浓度分别为10、15 mg/mL;定性分析发现,经脱胶后的罗布麻纤维仍对细菌类的金黄色葡萄球菌和大肠杆菌具有一定的抑制作用,但对霉菌类的黄曲霉无明显抑制作用。
