Assessment of the extent implementing the Good Manufacturing Practices (GMPs) and Hazard Analysis Critical Control Point System (HACCP) in Sudan sugar industry factories

The present study was conducted in Sudan Sugar industry factories (Kenana, White Nile, Assalaya, Sennar, Guneid, and New Halfa) during the production season of 2017. The study aimed to evaluate the existing Assessment of the extent of implementing the Good Manufacturing Practices (GMPs) and Hazard Analysis Critical Control Point System (HACCP) by Sudanese sugar factories with reference to FSMS of the ISO 22000: 2005. The data were collected using ISO 22000 checklist and direct interviews. Likert Five-Point Scale was used in scoring the checklist statement and the arithmetic mean was obtained. The result showed that the Good Manufacturing Practices were varied between major deficiencies in White Nile, Assalaya, Sennar, and New Halfa due to score less than (3.6 points) and non-compliance in Kenana and Guneid due to score less than (2.6 points); the Sanitation Standard Operation Procedures (SSOP) assessed as major deficiencies in (Assalaya and Sennar) and minor deficiencies in (White Nile and New Halfa) due to score less than (5points). Moreover, the Hazard Analysis and Critical Control Points System revealed that it was varied between non-compliance in (Kenana, White Nile, and Guneid) and not applicable in (Assalaya, Sennar and New Halfa) due to score less than (1.8 points). Interestingly, the Sudanese sugar industries take all quality control characteristics from cane production to sugar production carefully, but unfortunately don’t care about any food safety systems. Lack of top management commitment and involvement and lack of government support represent the main constraints and Barriers of implementing food safety systems in Sudanese sugar companies. The study recommendations that the Sudanese Sugar Industry needs to establish proper quality assurance laboratories to help in monitoring the quality and safety of raw materials and end productions.

Reflections on almost a century of hydrological studies on Africa's largest lake

Lake Victoria is the largest lake in Africa and its outflows strongly influence flows in the White Nile, including the availability of water for hydropower generation, irrigation and water supply. Understanding the water balance is a major challenge since the lake is large enough to influence the local climate and its catchment spans several countries. Hydrometeorological monitoring networks are also sparse in some parts of the basin. In this paper, we consider the history of water balance estimates for the lake and how the science has developed as new information and techniques have become available, including in areas such as seasonal flow forecasting and estimating the potential impacts of dam operations and climate change. These findings are placed into a wider context including the challenges arising from a changing climate and evolving ideas from international research programmes, which lead to some suggestions for future research priorities for Lake Victoria and other sub-Saharan/Rift Valley lakes.

Transmission Dynamics of Schistosoma haematobium among School-Aged Children: A Cohort Study on Prevalence, Reinfection and Incidence after Mass Drug Administration in the White Nile State of Sudan

The reinfection rate of schistosomiasis after mass drug administration (MDA) has not been documented in Sudan. We aimed to explore the transmission dynamics of urogenital schistosomiasis after MDA, targeting school-aged children in the White Nile State of Sudan, assessing the prevalence, reinfection rate, and incidence. A single dose of praziquantel (40 mg/kg) was administered to 1951 students in five primary schools from January to February 2018 immediately after a baseline survey, and follow-up surveys were performed at 2 weeks and 6 months after treatment. We examined Schistosoma haematobium eggs by centrifugation methods. The overall reinfection rate at 6 months after treatment was 9.8% (95% confidence interval: 0.5–17.4%). By school, the reinfection rate was highest in the Al Hidaib school, whose prevalence was highest at baseline. The reinfection rate was significantly higher in high-infection areas than low-infection areas (p = 0.02). Of the prevalence at 6 months in high-infection areas, 41% of cases were due to reinfection. MDA interventions are decided upon and undertaken at the district level. A more targeted treatment strategy should be developed with a particular focus on tracking high-risk groups, even within a school or a community.

FISH COMMUNITY COMPOSITION INDICATES LOW IMPACT OF CAPTURE EFFORTS IN WAR-TORN SOUTH SUDAN

A survey conducted in Terekeka, Mongalla (=Mongalla) and Gemmaiza (= Gemeiza), payams of Central Equatoria in South Sudan using face-to-face interviews, structured questionnaire and focused group discussion provided information on income generating strategies of fishing communities. These included: full time or part time fishing, small-scale farming, cattle breeding and firewood collection. Stationary gill nets were the dominant type of fishing gear, followed by monofilament, hook and long line, cast nets, spears and harpoons. Fishing vessels included planked canoes, steel boats and fibreglass. The best fishing months were August, September, followed by May. Main species caught included large bodied potamodromous predators adapted to channel habitats, as well as floodplain migrants. Overall the fish community appeared to be at equilibrium, with no evidence of impacts due to excessive catch efforts. The good health of the White Nile fishery is related to the high resilience of South Sudanese aquatic ecosystems as well as to the low potential of fish capture in a country disrupted by war and lack of security.

Derived karyotypes in two elephantfish genera (Hyperopisus and Pollimyrus): lowest chromosome number in the family Mormyridae (Osteoglossiformes)

The African weakly electric elephantfish family Mormyridae comprises 22 genera and almost 230 species. Up-to-date cytogenetic information was available for 17 species representing 14 genera. Here we report chromosome number and morphology in Hyperopisus bebe (Lacepède, 1803) and Pollimyrus isidori (Valenciennes, 1847) collected from the White Nile system in southwestern Ethiopia. Both taxa displayed the diploid chromosome number 2n = 40, but they differed in fundamental numbers: FN = 66 in H. bebe and FN = 72 in P. isidori; previously the same diploid chromosome number 2n = 40 was reported in an undescribed species of Pollimyrus Taverne, 1971 (FN = 42) from the same region. Our results demonstrate that not only pericentric inversions, but fusions also played a substantial role in the evolution of the mormyrid karyotype structure. If the hypothesis that the karyotype structure with 2n = 50–52 and prevalence of the uni-armed chromosomes close to the ancestral condition for the family Mormyridae is correct, the most derived karyotype structures are found in the Mormyrus Linnaeus, 1758 species with 2n = 50 and the highest number of bi-armed elements in their compliments compared to all other mormyrids and in Pollimyrus isidori with the highest number of bi-armed elements among the mormyrids with 2n = 40.

Isolation and Identification of Dermatophytes from Environmental Specimens Comparing with Species Isolated from Clinical Specimens of Scalp Infection among Sudanese Basic School, Kosti, White Nile State, Sudan -2020

Background: Tinea capitis (TC) or scalp ringworm is common in pediatric population with reported rates of infection ranging from 4% to 15 % .T.rubrum is rarely reported in countries with a temperate climate . There is always hair loss with varying degrees of scaling and erythema [1-3]. Objectives: To identify the role of soil, plant & sewage in transmission of ringworm of scalp infection. This study was carried out on Kosti basic school students who suffering from ringworm of scalp (fungal infection) in White Nile state at Sudan in 2020. Methodology, Data Analyses and Results: Due to preservation of this fungal infection among school children in Kosti basic school students, a total of fifty specimens collected from different sources to determine the source of this infection in the area of study, twenty five students who suffering from ring worm of scalp and twenty five from soil, sewage, water and trees in the period between January – December -2020.The samples collected by scraping the scalp by surgical blade and removing the hair with needle and forceps from the peripheral lesion and gathered in filter paper and closed tightly,10% KOH was used to clarify and keratinized tissues. Trees samples were collected by washing the tree’s leaves and with all soil, sewage, water were collected into container. All samples were cultured on sabouroad dextrose agar medium for one week at room temperature. After growth, lactophenol cotton blue staining was used to identify depending on the colonial morphology under microscope and tolook for color, septate, aseptate hyphae, macro, micro conidia and spores. The results showed that there was 68% of isolates from soil, sewage, water and trees were matched to scalp isolates. The soil is significant one of these when Chi-square (X2) was used (P value = 0.027) that means, the source of infection among students may be due to soil transmission. Conclusion and Recommendation: Our results highlight the epidemiology of fungal infection of Kosti basic school students. Further studies are necessary to verify these findings considering the relatively high rate of fungal infection to cover all expected area with similar observation.

Quantitative Contributions of Climate Change and Human Activities to Vegetation Changes in the Upper White Nile River

Vegetation changes in the Upper White Nile River (UWNR) are of great significance to the maintenance of local livelihoods, the survival of wildlife, and the protection of species habitats. Based on the GIMMS NDVI3g and MODIS normalized difference vegetation index (NDVI) data, the temporal and spatial characteristics of vegetation changes in the UWNR from 1982 to 2020 were analyzed by a Theil-Sen median trend analysis and Mann-Kendall test. The future trend of vegetation was analyzed by the Hurst exponential method. A partial correlation analysis was used to analyze the relationship of the vegetation and climate factors, and a residual trend analysis was used to quantify the influence of climate change and human activities on vegetation change. The results indicated that the average NDVI value (0.75) of the UWNR from 1982 to 2020 was relatively high. The average coefficient of variation for the NDVI was 0.059, and the vegetation change was relatively stable. The vegetation in the UWNR increased 0.013/10 year on average, but the vegetation degradation in some areas was serious and mainly classified as agricultural land. The results of a future trend analysis showed that the vegetation in the UWNR is mainly negatively sustainable, and 62.54% of the vegetation will degrade in the future. The NDVI of the UWNR was more affected by temperature than by precipitation, especially on agricultural land and forestland, which were more negatively affected by warming. Climate change and human activities have an impact on vegetation changes, but the spatial distributions of the effects differ. The relative impact of human activities on vegetation change accounted for 64.5%, which was higher than that of climate change (35.5%). Human activities, such as the large proportion of agriculture, rapid population growth and the rapid development of urbanization were the main driving forces. Establishing a cross-border drought joint early warning mechanism, strengthening basic agricultural research, and changing traditional agricultural farming patterns may be effective measures to address food security and climate change and improve vegetation in the UWNR.
